What is family molding?
The concept of family molding is derived from the family mold. A family mold is a multi-cavity mold with a common mold plate shared across the cavities. It is designed to produce multiple parts with different cavity configurations in a single shot.
A standard multi-cavity mold produces several identical parts in one cycle, such as four identical buttons, to maximize output for a single component.
A family mold produces several different parts of an assembly in one cycle, such as one top enclosure, one bottom base, and two side buttons, so you can make all assembly components in a single shot.
Why Choose It?
Group related parts into one mold. Skip extra mold bases, cooling, and setups—cut NPI tooling costs by up to 50%.
Molded together from the same resin batch and barrel temperature, so color and texture stay consistent.
Every shot makes a full assembly set, so you never end up with 5,000 left shells and only 4,800 right.
One mold to machine, sample, and validate is often faster than juggling three.
Your Family Molding Supplier
This is a common one-stop solution for multi-component injection molding needs, which can help you reduce costs and ensure precision.
High-precision Molding
Advanced mold design and precise process control ensure the dimensional accuracy of each part, reaching the industry-leading standards.
Efficient Production
Family Molding reduces the running times of injection molding machines and the frequency of mold replacement, significantly improving production efficiency and saving time and costs.
The technological advantages of family mold help to boost orders
Mold Design
Mold designers are proficient in unique algorithms for optimizing the layout of cavities. This ensures that the plastic melt fills each cavity evenly and avoids defects like short shots and flash.
Process Control
With a reasonable department structure and good collaboration, we make use of advanced equipment control systems to monitor and accurately adjust parameters like temperature, pressure and speed in real time.
Quality Inspection
From the inspection of raw materials to the random inspection of finished products, we use a variety of professional testing equipment, such as high-precision coordinate measuring machines and material property testers.
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;
