Accurate raw material preparation
High-quality silicone raw materials are the prerequisite for ensuring product performance. Raw materials with appropriate hardness, transparency, and environmental certification level (such as FDA, LFGB) must be selected according to the product use.
Formulation and rubber mixing technology
The scientific nature of the formula determines the functional performance of the product. Add vulcanizers, masterbatches, functional powders (such as luminous powder, conductive particles), etc. according to customer needs. The mixing time, temperature and ratio must be strictly controlled to ensure uniform mixing.
Standardized cutting
Use automatic cutting or precise molds to cut silicone into rubber materials with consistent specifications, ensuring the standardization of thickness, length and width, providing a good foundation for molding.
Wake-up material management
The cut rubber material should be left to stand in a clean environment for more than 8 hours to release its internal tension and improve its stability and dimensional consistency during subsequent hot pressing.
Compression molding control
The mold temperature, pressure and time settings must be accurate to avoid incomplete or over-curing of the silicone. At the same time, the mold should be cleaned regularly to avoid dirty marks.
Trimming and appearance treatment
The edge removal process must be delicate to prevent scratches on the product. Subsequent spraying, silk screen printing, laser engraving, etc. can enhance the aesthetics and functionality of the product, and require special process flow and ink formula.
Quality Inspection
A quality inspection step should be set up after each process, including appearance, size, elasticity testing, etc., to ensure that defective products do not flow into the next process.
Packaging and logistics control
Qualified products must be packed and labeled according to customer specifications, and desiccant and buffer materials must be added when necessary to ensure transportation safety and showcase the brand image.
Summarize
Behind the high-quality silicone products are the eight major links of control and process optimization. Through standardized production processes and detail management, the factory can effectively reduce the defect rate and improve customer satisfaction and repurchase rate.
