What is family molding?

Family molding is an efficient and common injection molding process. It is a strategy for producing multiple related plastic products in the same injection molding cycle. The core of this process lies in the utilization of family mold. Family mold is a kind of mold that can set up cavities for multiple different parts in the same set of molds. During the family molding process, through this special family mold, the plastic melt fills into the cavities of various parts simultaneously according to the pre-designed runner system.

For example, in the manufacturing of automotive interior parts, a family mold used for producing multiple components such as handles and storage boxes on the door interior panel enables these components to be injection molded under the same process conditions (such as the same temperature, pressure, injection speed, etc.) during family molding.

Design Concept and Precision Machining of Family Mold

In the Family Molding process, the family mold is as crucial as the cornerstone. Its quality and precision are directly related to the success or failure of the entire injection molding process. A high-quality family mold is the core element to ensure the efficient and precise operation of Family Molding.

Design Concept of Family Mold

Multi-cavity Adaptive Layout: According to the matching requirements of products, the cavities of parts with different shapes and sizes are skillfully arranged.

Optimized Runner Design: The runner is planned based on the characteristics of plastic materials. For plastics with weak fluidity, the main runner is widened; and the gate is selected according to the shrinkage rate. For example, a pinpoint gate is used for high-precision plastic parts to ensure molding accuracy.

Precision Machining of Family Mold

Ensuring Accuracy through CNC Precision Milling: High-precision CNC milling is adopted, and complex cavities are processed with five-axis linkage to create a smooth surface with micron-level accuracy

Enhancing Performance through Strengthening Treatments: Heat treatments such as quenching and tempering are carried out to adjust the hardness and toughness according to the force on the mold;
