The post TPU vs. TPE: Engineering Applications, Properties & Selection Guide appeared first on First Mold.

Basic Principles of GAIM

Operators introduce precise amounts of gas into the mold cavity through gas-assisted injection molding. The molten plastic process occurs before the completion of gas mounting. The gas produces a hollow central area within the existing part. The core allows manufacturing processes to reduce both the materials and weight requirements. The method maintains the structural quality and integrity of the system.

Injection of Material

The gas-assisted injection molding starts standard injection molding. There is the placement of injection molten plastic in the high-pressure and mold cavity. Under strong force, the plastic is put in the mold to create an accurate part form. The products from GAIM are superior to those from standard injection molding.

Gas Injection Stage

Nitrogen gas passes through a well-craft nozzle upon filling the core. The gas passes through the gas channels through the plastic material. It develops pressure that adjusts the molten plastics in the core. The process minimizes the amount of material applicable, thin outer walls, and gas bins.

Cooling Stage

The third phase of the gas-assisted injection molding process is the cooling phase. The cooling phase requires time as the product’s shape is already in place. The cooling phase precedes the gas injection phase. The objective is to solidify the plastic material on the gas bubble. The process follows gas navigation to a cross-section of a gas channel. The approach is generally semi-circular. The solidification as a process ensures the hollow section does not collapse. Additionally, it is responsible for maintaining a uniform cooling rate for gas. This cooling process is vital in helping plastics solidify effectively.

Ejection Molding

The final stage is mold ejection. It entails opening the mold to release the finished part. Entering the mold should happen before the designated period expires. The gas plays an essential role when the mold opens to escape through the air gap. The hollow cavity inside the mold part completes the remaining segment. After mold formation, the part exits through the open mold section.

Key Proponents of the GAIM

A proper structure of essential components remains critical for gas-assisted injection molding.

• Gas Injection System: Masters of gas injection systems facilitate the gas-assisted injection molding operation. The system contains nitrogen supply pressure regulation and a control valve that controls the gas flow. The nozzle uses its design to transport existing gas to the mold cavity.
• Injection molding machine: Special valves and controls for gas flow management significantly alter standard injection machines through their gas injection system integration. Manufacturers implement the updated manufacturing equipment to perform simultaneous manufacturing of standard pieces as well as gas-assisted molding from a single installation. It lowers manufacturers’ production expenses.

模具设计

The designed molds contain gas-assisted features for proper airflow which generates hollow elements within molded components. Assembling the appropriate mold design remains essential to achieve proper gas distribution. The gas travels through specific fractures along the lines of weakness to form an essential section. The injection molds must contain features which allow gas to enter the mold space.

Comparison with Standard Injection Molding

The Materials in Gas-Assisted Injection Molding require performance enhancement due to this method’s efficiency factor. Past and old-age injection molding demands complete cavity material for part formation. The impact is the high amount of material used, especially for thick and large parts. On the other hand, the gas creates a hollow center. The effect is the low amount of material used to maintain strength and durability.

Reduction of Weight: Limited material usage offers an advantage in weight reduction. The gas-assisted molding process develops hollow sections at the center of the part, resulting in less weight and increased strength. Standard injection Molding requires a fill in the cavity, which incurs extra weight costs. The fill is, therefore, a waste compared to gas-assisted molding.

Surface Finish and Quality: Gas-assisted injection molding can offer more surface finishes than parts from standard injection molding. The pressure from the gas injection helps remove the material flow, air, and imperfections.

Cycle Timeframe: Gas-assisted molding processes need more time than standard injection molding to execute a cycle. The entire process needs longer durations than cooling time during gas injection. The cycle time sometimes completes its execution within a short period. Standard injection molding technology faces challenges when processing short-timers, which become difficult in complex shapes and lightweight applications.

Flexibility of Part Design: GAIM excels when part creation requires complex geometries. It also leads to thin walls and technical internal structures. Creating hollow cores in product designs proves difficult or unachievable with standard injection molding processes.

When to Use Gas-Assisted Injection Molding

Industries that need premium surface finish quality find gas-assisted injection molding an essential technology. The gas pressure helps eliminate errors and defects from air traps. It also allows flow lines and sink marks, typical for standard-assisted processes that produce thick walls. The smoother surface finish minimizes the demand for post-processing.

Significant Parts and Weight Reduction

Machine defects lead to most of the reported accidents throughout industrial facilities. Determining these three key elements is essential for engineers when they design machines. Plastic prototypes are necessary tools when used in such applications.

Plastic materials enable testing and defining the operation of industrial equipment, which functions best under severe thermal heat and intense friction conditions. The employment of refinement methods during component design allows improved assembly mechanics and lower friction, resulting in enhanced mechanical output. FEA analysis enables industries to locate the regions where products can fail before their expected useful life.

Steps to Create a Plastic Prototype

步骤 1：确定目标和要求

The proper goal is an essential element of engineering design. While creating the plastic prototypes, engineers must start by defining their goal. The goal can be linked to the requirements of the prototype. The goal originates from the problem the prototype needs to solve. The examination capabilities of prototypes for testing depend heavily on how well their mechanical properties align with the ones expected in the final manufactured product. The main aim of visual demonstration prototypes is to achieve high surface quality and precise component details. User feedback prototypes require improved ergonomics and appearance—efficient design results from determining the primary purpose initially.

Project financial limitations determine which materials will be used, production techniques, and equipment expenses. The choice between 3D printing and CNC machining depends on prototype volume requirements, but injection molding has become essential for high-volume manufacturing. The selection of affordable manufacturing methods that do not affect product quality leads to economic sustainability. The following is the equation for determining the total cost of creating the prototype.

C_总计=C_m+C_p+C_pp

C_总计 is the total cost, C_m is the cost of raw materials, C_p is the processing cost, and C_pp is the post-processing expense.

A timeline designed for realism helps maintain project progress. The project must define time constraints for all development phases, from design through manufacturing to testing. The entire manufacturing timetable depends on lead times for material acquisition, machining operations, and post-processing activities. The total time for the project is given as:

T_总计=T_d+T_m+T_t

T_总计 is the design time, T_m is the manufacturing time, and T_t is the testing time. 

步骤 2：三维设计和建模

The precision level of a 3D model establishes all critical quality standards needed to produce successful plastic prototypes. The software program Computer-Aid Design (CAD) allows engineers to create improved prototype designs using the application’s tools. A design that has undergone proper optimization enables products to be manufactured efficiently while delivering outstanding performance at a reasonable price.

Choose the Right CAD Software

Good prototype production depends on advanced CAD programs that enable engineers to design precise 3D models.

SolidWorks gives its users strong parametric modeling capabilities for mechanical and industrial designs, yet Fusion 360 shines best when used for surface models requiring cloud collaboration. The software features the best capabilities for 2D drafting and simple 3D modeling applications. The two programs, CATIA and NX, serve high-precision industrial and automotive applications because of their powerful capabilities. Using feature-based modeling within design enables developers to establish geometric constraints, set tolerances, and define design intent, thereby creating solid and producible plastic prototypes.

Optimize for Manufacturability

Creating a manufacturable plastic prototype decreases manufacturing problems along with production expenses. The main factor to consider during design involves reducing unsupported structures and overhangs. Any angled overhang beyond 45 degrees in 3D printed parts needs support structures that cause elevated material waste and post-printing procedure time. The acceptable limit for overhang angles reaches a maximum at:

θ_max≈45°

Self-supporting angles or design fillets should be integrated whenever overhangs become inevitable to minimize the need for support. Correctly examining wall thickness gains fundamental importance since walls of low quality eventually warp or break when they experience stress. During manufacturing processes, maintain minimum requirements for material circumference specifications.

Achieving balanced cooling and lower stress development becomes possible by maintaining uniform wall thicknesses. You should correctly utilize rib reinforcements to counteract thin section weakness without producing unnecessary material weight. The formation of acute internal corners leads to localized stress buildup, heightening the chance of material failure. Fillets agree to spread out stress distribution throughout the material. The calculation for Stress Concentration Factor (SCF) appears as follows:

K_t​=1+2(r/d)

Residents require this fillet radius to be r and section thickness to be d. The recommended minimum fillet radius for injection-molded parts amounts to 0.5× wall thickness to improve component durability alongside failure risk reduction.

Ensure Strength, Aesthetics, and Functionality

Engineers involved in plastic prototype manufacturing should establish structural integrity methods while building aesthetics and functional testing capabilities. Finite Element Analysis (FEA) permits the simulation of fundamental forces, enabling researchers to assess Von Mises Stress distributions throughout the system.

σ_v​=√[(σ₁​−σ_2​)²+(σ_2​-σ₃​)²+(σ₃​−σ₁​)²​​]/2

地点 σ₁, σ_2​和 σ₃ are principal stresses. Material fails only if stress remains below its yield strength (σ_yield).

Surface textures applied to parts diminish imperfections in injection molded components, and together with matter finishes, they resolve glare issues and fingerprint smudges. Visual prototypes need finishing treatments, including coating or polishing procedures, to achieve advanced quality.

Step 3: Choose a Prototyping Method

Multiple techniques exist to match plastic prototyping processes’ speed, accuracy, and cost-effectiveness. The three-dimensional printing methods FDM SLA and SLS provide manufacturing techniques to build plastic parts.

These techniques produce complex shapes together with accelerated development cycles. The quick and budget-friendly solution works perfectly for making a few items simultaneously. CNC machining is the prime method for producing high-precision prototypes since it delivers excellent durability and precision with repeatability capabilities, making it ideal for functional testing and mechanical validation.

Companies, including First Mold, benefit from the rapid tooling injections as a form of production of plastic prototypes. This technology enhances the development of high-quality mass outputs. Organizations enjoy competitive price benefits for production requirements. For manufacturing small batches, the vacuum casting process generates outstanding results because it duplicates the specifications of injection molding while offering various flexible material choices.

步骤 4：材料选择

The selection of appropriate plastics determines the success of obtaining the required mechanical traits, thermal behavior, and aesthetic qualities in plastic prototypes. Consumer electronics and automotive parts utilize Acrylonitrile Butadiene Styrene (ABS) as their material of choice because it offers exceptional strength and strong impact resistance.

Step 5: DIY vs. Outsourcing

Choosing whether to manufacture the plastic prototype within the organization’s production line or to outsource it from other manufacturers depends on numerous factors. While Fastmold engages in the production of these products, some of the different parts are outsourced. As an engineer, one must assess the factors of production, including the availability of the materials, the production time, and the product’s urgency.

For instance, with a well-defined production line and machinery, First Mold mainly considers DIY rather than outsourcing. The initial stages of development and fast design modifications show the best performance for the DIY prototyping method. You can use your available 3D printers or CNC machines to do prototyping inside your organization, which offers better control and quicker results at a similar budget level. DIY techniques show weaknesses in producing components with high precision, tight tolerances, and advanced material performance.

Professional manufacturers should be selected to produce plastic prototypes that require high accuracy, complex geometrical features, and manufacturer-grade quality. Specialized vendors outperform internal equipment by providing high-precision CNC machining, injection molding, and industrial-grade 3D printing capabilities. Expert manufacturers enable customers to access numerous materials alongside diverse finishing options and post-processing methods through outsourcing. The planning process for outsourcing needs attention because different providers have different lead times and cost structures.

Acquiring vendors for outsourcing requires an assessment focused on price elements, building timeframes and production abilities, and consumer testimonies. Verify that the manufacturer operates according to industry standards while offering consistent delivery throughout your predetermined time frame.

Step 6: Testing and Iteration

Plastic prototype manufacturing reaches a crucial point with testing. Testing demonstrates whether the design fulfills its functional demands. Testing also ensures that the product meets mechanical requirements and aesthetic standards. The evaluation of key elements through functional testing uses simulations that reproduce actual conditions to detect weaknesses before product release. Engineers deploy finite element analysis (FEA) to forecast how stress will distribute itself and how objects will deform throughout their structures. Physical testing enables manufacturers to check product integrity through drop testing load-bearing examinations and thermal stress resistance evaluations of chosen materials.

Customer opinions about product functions are fundamental in developing a better prototype. Laboratory testing with end-users, engineers, and stakeholders demonstrates the valuable capability of identifying system-related issues that affect usability while detecting user-friendly changes to physical appearance. Mobility element testing should address functional efficiency, ease of assembly, and tactile perception to meet product requirements. The prototype benefits from multiple performance upgrades through direct input from real-world applications, which results in enhanced usability among end-users.

The first step of the design enhancement strategy involves collecting data from received feedback. Engineers modify the CAD model before generating the new version by changing tolerances, improving geometries, and implementing design modifications. Iterative product refining ensures that manufacturers meet the required properties. This process eliminates possible errors in meeting customers’ demands.

Cost Saving in Plastic Prototyping

Cost-effective materials should be selected first as an expense-reduction approach for plastic prototypes while aligning with prototype goals. Concept models stay budget-friendly at the initial design stages by applying PLA and ABS materials since they deliver excellent performance with lowered expenses. When selecting functional prototype materials, choosing materials that exhibit both strength characteristics and minimum expense and durability factors is crucial.

Experts use written design optimization techniques to reduce materials during production and speed up machining operations, thus lowering manufacturing costs. Engineers perform these objectives through simplified support elements, uniform wall dimensions, and eliminating every hardware component.

To minimize expenses, selecting proper prototyping technologies must match the production quantity and design complexity level. Low-volume technical designs benefit from 3D printing, and complex high-precision production uses CNC machining. When industrial production outsources to plastic prototype manufacturers, it receives specialized expertise at bulk discount prices through access to advanced production equipment. Suppliers should be evaluated through these factors to achieve the best solutions, combining cost-effectiveness with excellent quality and fast delivery.

Case Studies & Tools

Using plastic prototyping techniques significantly saves industrial production according to practical industry applications. The manufacturing costs of a consumer electronics startup decreased by 40% through the utilization of 3D-printed plastic prototypes in the early testing phase. Through FDM and SLA printing iterations, the company detected problematic design flaws, preventing related to expensive injection molding tooling. The early implementation of this approach saved manufacturing expenses and avoided unnecessary tool and rework expenses, simplifying mass production readiness.

SolidWorks and Fusion 360, along with ANSYS, drive efficiency through their roles in CAD modeling simulations and structural analysis. Design validity material optimization and stress testing of designs become possible through these tools during the production period before physical manufacturing begins. The manufacturing cost estimation software aids engineers in comparing product expenses between materials and production methods alongside suppliers to find the most economical prototyping solution.

结论

Before committing to mass production, businesses must design plastic prototypes that confirm functionality and product design through testing while enhancing manufacturing process efficiency. Companies achieve their prototype requirements by defining goals, selecting appropriate materials, and using proper plastic manufacturing methods for prototype creation.

Repeated testing and improvement cycles can improve product performance and cost efficiency. Appropriate prototyping of plastic methods with internal resources or external manufacturers helps speed up innovation speed and risk reduction for a smooth transition from ideas to mass production.

创建金属原型的步骤

开发金属原型需要特定的步骤，这些步骤有助于在实现可制造性的同时，获得精确的尺寸和操作能力。工程师的首要任务是确定如何将原型用于机械评估、目视检查或操作测试。

原型开发从 CAD 软件建模开始，然后选择适当的制造方法，包括数控加工、金属 3D 打印和熔模铸造。

材料的选择仍然至关重要，因为金属具有不同的强度等级，同时在热性能和腐蚀能力方面也各不相同。阳极氧化、电抛光和粉末喷涂等表面处理操作可提高制成品的耐用性和外观。

原型必须通过应力、温度和配合质量参数的三个测试阶段，才能获准批量生产。

步骤 1：确定目标和要求

金属原型制作流程始于准确的目标定义，以实现卓越的性能、可制造性和经济价值。工程团队应根据产品要求和使用规范确定精确的目标，以便在金属原型制作中取得成功。

原型目的和设计参数

工程师的基本步骤首先是决定金属原型的具体用途。这一决定设定了指导材料、生产方法和质量控制程序的参数。

机械和热测试方法

对结构原型进行严格的机械测试可确定其承载性能、耐用性和失效特性。通过有限元分析（FEA），工程师可以对应力模式和变形预测进行模拟，然后进行设计优化，从而获得更好的物理测试结果。

为了验证理论预测，使用万能试验机、应变仪和数字图像相关系统对原型进行了测试。对热循环设计原型的工程评估包括使用热机械分析仪（TMA）和激光闪光分析仪（LFA）测量其热膨胀率、传导性和抗疲劳性评估。

美学与功能验证

美观的原型既需要精确的表面质量，也需要精确的产品尺寸。工程师们使用精细的光学轮廓仪来评估产品的表面质量，主要用于满足美观要求的消费品和汽车零部件。通过坐标测量机 (CMM) 和激光扫描技术的评估，可以满足 GD&T 和公差标准的要求。

原型的功能要求精确模拟机械动作的实际性能以及热调节和电气功能。要评估环境试验箱中的极端环境条件，工程师需要使用示波器和频谱分析仪来执行基于信号完整性和传导性评估的电气测试。原型机的测试计划取决于其设计目的，以验证是否达到预期性能以及可靠性和可制造性标准。

结合使用 CAD 建模、模拟分析和精密验证，可制造出达到最佳强度、实用制造标准和运行性能结果的金属原型。

步骤 3：选择金属原型制作方法

决定采用哪种方法制作功能性金属原型，决定了能否成功地将材料规格与精确度和经济效益结合起来。工程师的评估过程包括检查公差需求、表面光洁度规格、机械阻抗能力和生产可扩展性等方面的考虑因素。

制作精密原型的首选方法是使用数控加工，因为它可以加工多种金属，公差严格控制在 ±0.01 毫米以内。钣金加工最适合薄壁组件和外壳，因为它能提供更快的周转时间并降低成本，但在加工复杂几何形状时能力有限。选择性激光熔融（SLM）和直接金属激光烧结（DMLS）金属三维打印技术可实现非凡的几何形状，但其成本要高得多。

高精细的小型部件和出色的表面光洁度可以成功地要求将熔模铸造作为其生产方法。制造商将这种工艺广泛应用于航空航天和医疗技术领域，因为它生产的零件废料少、尺寸精确。由于模具准备和金属凝固需要大量时间，因此该工艺需要十四到二十一个工作日。

使用快速模具进行压铸，可制造出保持稳定质量规格的可扩展部件，因此可从试生产试验中获益。模具生产的主要缺点是价格昂贵，不适合小规模生产。工程师必须根据产品生产水平和扩展的经济性能检查来决定采用哪种方法。

不同金属原型制作方法的重要因素比较见下表。

最佳方法取决于不同的工程目的，需要进行复杂的设计评估、产量分析和机械性能要求。ANSYS、COMSOL 和 SolidWorks 仿真工具可帮助工程师在确定金属原型生产技术之前，确定热膨胀影响以及残余应力和变形威胁。

步骤 4：材料选择

选择制作金属原型的材料是开发项目中至关重要的一步。不同的材料具有不同的特性，因此适合其他应用。在选择材料时，一些考虑因素包括耐用性、机械质量和功能性。腐蚀、热应力和负载应力等环境因素决定了不同材料的选择。

步骤 5：表面处理

表面处理的选择取决于材料特性以及产品的机械和环境暴露需求。通过电化学形成坚硬的氧化层，在保持原有尺寸的同时增强材料强度。通过静电聚合物粉末在加热条件下固化形成的粉末涂层，可形成一层耐用的保护层。涂层采用先进的电化学处理工艺，提高了抗划痕和耐化学性，因此适用于需要大量磨损的汽车和工业部件应用。

电解抛光是一种精加工工艺，适用于需要精确尺寸和光滑表面的应用。电化学溶解可以消除微小的表面缺陷，形成光滑的镜面，从而提高耐腐蚀性。不锈钢医疗植入物以及航空航天部件和精密工程零件都能从电解抛光中受益，因为电解抛光能去除毛刺，使表面更加光滑。不锈钢表面经过钝化处理，通过去除游离铁和表面污染物来提高耐腐蚀性。通过这种工艺形成的氧化铬保护层可使部件在要求苛刻的海洋和化学加工应用中寿命更长。

步骤 6：测试和改进

如何测试金属原型的抗疲劳性？

测试至关重要，因为它可以验证金属原型的所有机械、热和功能方面，为全面制造做好准备。原型必须经过静态和动态力测试，以确定其承载能力、抗拉强度和抗疲劳性。有限元分析模拟可帮助工程师确定应力在结构元件中的分布情况，并发现潜在的失效位置，同时验证工作应力的设计能力。使用万能试验机（UTM）进行单轴拉伸试验，以验证材料在物理条件下的实际性能。

在高温条件下测试部件至关重要，因为这会影响到汽车发动机、航空航天结构和工业机械等部件。工程师要对原型进行热循环和耐热性评估，以分析材料的膨胀情况（CTE），同时确定散热水平并检查极端温度下的结构稳定性。

配合测试程序通过确认原型与其他装配组件的顺利整合来检验原型的性能。工程师根据 CAD 设计检查产品时，使用坐标测量机和 3D 激光扫描仪确定尺寸的真实性和形状的符合性。在 CAD 软件中对参数进行软件调整后，可对设计进行改进，然后再进行其他开发周期，生产出新的原型。工程师可以通过数控机床操作、金属三维打印和快速铸造方法快速更改设计，从而在基于测试的修改后快速实现原型。通过对原型的反复改进，制造商可以减少缺陷，提高材料效率，从而优化生产效果，确保在产品发布前准确遵守性能和行业标准。

案例研究：利用金属样机提高性能

自行车行业通过一个真实案例展示了 Specialized Bicycle Components 如何应用金属原型技术提高产品性能。作为一家领先的高性能自行车公司，Specialized Bicycle Components 使用钛三维打印技术（选择性激光熔融技术 - SLM）制造 S-Works Power with Mirror 车座的结构框架。Specialized Bicycle Components 在对铝合金和碳纤维原型进行研究后发现，他们的产品需要更耐用、更轻便的特性。该产品通过采用 3D 打印钛来替代以前的材料，从而提高了性能和舒适度。
