Mold Making – The Core Carrier for Precise Replication, a Bridge Between Design and Finished Products

If silicone rubber compounding is regarded as laying the foundation, mold making is all about defining the shape. As the core carrier connecting product design and mass production, the precision and durability of molds directly determine the dimensional accuracy, surface finish and production efficiency of finished products. A high-quality mold can precisely replicate design details and reduce the rejection rate, whereas a poor-quality mold not only causes defects in end products but also breaks down frequently, delaying production schedules and increasing manufacturing costs.

Mold making follows the principle of precision replication per drawings and accurate matching. First, designs are optimized and adjusted based on product blueprints, with key structures such as draft angles, feed ports and discharge ports properly reserved. Appropriate materials are then selected according to the characteristics of raw materials: aluminum alloy and stainless steel are commonly used for silicone product molds, prioritizing thermal conductivity and wear resistance; high-strength alloy steel is adopted for metal stamping molds to withstand high-frequency stamping pressure. Design optimization and material selection are the two essential prerequisites for ensuring mold quality, neither of which can be overlooked.

The core process consists of four stages: design, raw material processing, precision engraving, and assembly & commissioning. Designers use professional software to create mold drawings, which undergo strict review. Blanks are then produced through cutting and grinding, followed by engraving of details such as mold cavities and cooling systems using precision equipment. Finally, all components are assembled, and trial molding and commissioning are carried out. A qualified commission mold can be reused thousands of times, satisfying the filling requirements of compounded silicone rubber while providing precise positioning for subsequent dispensing and stamping processes.
