Based on the shape, size, and functional requirements of the product, 3D modeling design is carried out. The initial mold plan is confirmed, including the mold structure, mold specifications, number of cavities, etc. The design must consider draft angles, parting lines, and vent hole placement.

Mold Materials: Commonly used materials include P20 steel, 718 steel, NAK80 steel, S50-S55 steel, 738 steel, and 738H steel. For example, P20 steel is suitable for standard silicone molds, while 718 and NAK80 are preferred for high-precision and long-lifetime applications. Choosing the appropriate steel grade improves mold processing efficiency, reduces defect rates, and extends mold lifespan.

Food-grade silicone is selected, ensuring it meets food safety standards such as FDA and LFGB.

Additives: Color masterbatches (for color), curing agents, and other auxiliary materials are added as required.

The silicone, curing agent, and color masterbatch are mixed in the required proportions. The mixing mill is started, and the roller temperature is adjusted (usually below 40°C to prevent burning or loss of volatile curing agents). The raw silicone is wrapped around the front roller for a mill roll operation.

Through the refining process, the effect of poor dispersion of compounded materials is improved, ensuring even distribution of additives. During the refining process, cutting, folding, and other operations are carried out to ensure uniformity. The mixing temperature and time are adjusted according to the characteristics of the silicone and additives to ensure thorough mixing. The mixing time is usually 20 to 40 minutes. After mixing, samples are taken from different directions of the rubber compound for inspection to ensure the material quality meets the required standards.

Silicone cutting usually takes place after the compounding step, where the material is cut into the desired shape. This process mainly uses die-cutting, where pressure machinery, punches, and dies are employed to cut silicone sheets or strips to the dimensions and weight defined by the product design.

During the cutting process, it's important to ensure the accuracy and stability of the cutting equipment to guarantee precise dimensions and smooth edges of the silicone products. Attention must also be given to safety during operation.

The prepared silicone molds are cleaned to ensure there are no impurities on the mold surface, and to ensure mold sealing and stability, allowing for smooth demolding. This ensures that the silicone can evenly fill every corner of the mold, avoiding product damage.

The cut silicone material is placed into the mold. Under a specific temperature and pressure, a vulcanization reaction occurs, forming the desired shape. The compression and curing time and temperature are adjusted based on the properties of the silicone and the product structure.

Silicone products produced often have excess material at the edges or seams that need to be trimmed. After trimming, a full inspection is carried out, and the products are turned into finished goods. The trimmed finished products are then sent to the quality control department for further inspection, focusing on the trimming quality and ensuring no defective products are present. If any non-compliant products are found, they are reworked to ensure all products meet the required quality standards.

Product dimensions are measured to ensure they are within the customer's quality requirements. The secondary vulcanization process is carried out to ensure the products pass third-party certifications (such as FDA, LFGB, RoHS), ensuring they are non-toxic and safe for use.

Finished products are packaged and shipped as per customer specifications.

The factory is equipped with a mold storage warehouse, a finished product warehouse, and an ERP production management system to ensure the quality of customer products.
