Reviews from Automotive Industry Clients
Regarding our automotive industry clients, there’s always been one aspect we take particular pride in. Many of the auto industry clients who partnered with us at the company’s inception still maintain a close collaborative relationship with us to this day.
When we first started working with First Mold on the new car seat adjustment parts project, we were initially quite concerned. However, once they received the order, their professionalism in mold manufacturing quickly became apparent. They carefully improved the design for the complex undercut areas, avoiding the problem of difficult mold release. During injection molding, they were precise in material control, producing parts with excellent surface quality and strength. Although there were minor equipment issues, they fixed them quickly without affecting the timeline. A small number of metal connectors were CNC-machined with high precision, fitting perfectly, and the delivery was on time, making the vehicle assembly smooth. We would definitely work with them again.
Previously, we entrusted First Mold with the production of a car dashboard shell, which had a complex design and high demands on appearance and precision. They optimized the mold structure through simulation analysis to prevent cooling defects. The on-site processing was meticulous, with fine polishing. During injection molding, they repeatedly adjusted parameters and tested materials to meet standards for light resistance and texture, overcoming issues like color variation and brittleness. The CNC-machined metal frame was exquisite, and although the timeline was slightly delayed due to logistics issues, they actively coordinated and the final result exceeded our expectations. They are very reliable.
For the development of a new car model’s headlamp cover, we chose First Mold. In the mold, they reinforced thin-walled areas to prevent damage. They used special optical plastic for the injection molding, overcoming difficulties with forming and ensuring the transparency was up to standard, so the light refraction was correct. The metal clips that accompanied the part were precisely CNC-machined, and assembly went smoothly. Although there were delays in material supply, they proactively found alternatives and rechecked quality, delivering on time. The product greatly enhanced the headlamp's performance, and we were satisfied with the cooperation.
We handed over our car wiper bracket production project to First Mold, and at first, we had some doubts about manufacturing the bracket, which had complex curves and high strength requirements. In the injection molding process, they carefully selected durable, weather-resistant materials to address issues like rapid material aging and brittleness, producing a bracket with excellent toughness. There was a brief equipment glitch, but their maintenance team responded quickly and fixed the problem. The accompanying metal connecting shaft was CNC-machined with high precision, ensuring a perfect fit. The final delivery was on time, helping us launch our product as scheduled. We found them very reliable.
The design had to be aesthetically pleasing and in line with our brand style, while also being impact-resistant and corrosion-resistant. In the injection molding process, they experimented with several eco-friendly material combinations, successfully balancing both appearance and performance. The resulting hub covers had a long-lasting, bright color and were tough in texture. The CNC-machined metal clips were finely crafted and ensured secure installation. During the project, there were some delays in material supply due to environmental inspections, but First Mold actively found compliant sources and adjusted the production schedule. Although the delivery was slightly delayed, the product quality was excellent, and we will definitely continue working with them in the future.
