Material selection for Silicone Rubber Molded Parts

In terms of material selection, we have a wide range of silicone rubber products. Universal solid silicone rubber (HTV) has good processing performance and mechanical strength, and is suitable for manufacturing conventional components such as sealing rings and buttons; Liquid silicone rubber (LSR) has good fluidity and high molding accuracy, making it particularly suitable for the production of precision medical catheters, baby pacifiers, and other products that require high hygiene and precision. In addition, we also provide functional silicone rubber materials with added special additives, such as conductive silicone rubber for electromagnetic shielding components, flame-retardant silicone rubber to meet the fire safety requirements of electronic appliances, as well as food grade and medical grade silicone rubber to ensure that products meet strict safety standards and provide precise material solutions for different application scenarios.

Production process of Silicone Rubber Molded Parts

Our production process is rigorous and specialized. Firstly, mold design and manufacturing. Based on the product shape and size requirements, CAD/CAM technology is used for 3D modeling of the mold. High precision machining equipment is used to manufacture the mold, ensuring accurate cavity dimensions and smooth surfaces. For solid silicone rubber components, the raw rubber is mixed evenly with additives such as vulcanizing agents through a mixer, and then pressed into a suitable shape by a pre molding machine before being placed into the mold cavity and vulcanized under high temperature and high pressure to form; The production of liquid silicone rubber components adopts a two-component injection molding process, in which A and B components of liquid silicone rubber are mixed in proportion and injected into the mold cavity through a precision metering pump for rapid vulcanization at lower temperatures. After molding, the components undergo post-processing steps such as deburring and cleaning, and if necessary, secondary vulcanization is also performed to improve product performance and stability.

Silicone Rubber Molded Parts Surface Treatment

To optimize the performance and appearance of Silicone Rubber Molded Parts, we offer a variety of surface treatment solutions. For components that need to improve surface smoothness and reduce friction coefficient, coating treatment can be carried out, such as coating with organic silicon lubricant or fluorosilicon coating; To enhance surface hardness and wear resistance, plasma treatment or chemical coating technology is used. In terms of appearance decoration, identification, patterns, and colors are added to components through processes such as screen printing, transfer printing, and heat transfer printing; For medical or food contact products, special surface cleaning and sterilization treatment can be carried out to ensure that the products meet hygiene standards and meet the functional and aesthetic needs of different customers.

Silicone Rubber Molded Parts Dimensional Inspection

We strictly control the size detection process, using advanced detection equipment and scientific detection methods. Using high-precision coordinate measuring instruments and image measuring instruments, precise measurement of key dimensions of silicone rubber components, especially for complex shapes and precision parts, is carried out to ensure that tolerances are controlled within a very small range. At the same time, the physical properties of the product are tested using equipment such as hardness testers and tensile testing machines. In the production process, we implement multi-stage inspection, from the first piece full inspection in the mold debugging stage to the scheduled sampling and finished product full inspection in batch production. Once size or performance deviations are found, the reasons are immediately analyzed, and corrective measures such as adjusting mold parameters and optimizing vulcanization processes are taken to ensure the consistency and stability of product quality.
