The processing of liquid silicone rubber can be regarded as a perfect combination of materials science and engineering technology. The molding process begins with the precise mixing of two-component liquid raw materials, which are crosslinked and cured through a platinum catalytic system at room temperature or heating conditions. This feature allows LSR to use injection molding technology to complete the transition from liquid to solid state within seconds, with a production cycle much shorter than traditional rubber.

Precision manufacturing is the core advantage of liquid silicone rubber. The high-pressure injection system of the injection molding machine can inject materials into small mold cavities, achieving 0.1 millimeter level detail reproduction, which is crucial for high-precision products such as medical catheters and optical lens stents. Meanwhile, the low shrinkage rate of LSR (usually less than 0.1%) ensures the stability of finished product dimensions and reduces post-processing requirements.

Technological challenges also exist. Uneven mixing can lead to incomplete curing, and improper mold design may cause burrs or bubbles. To this end, manufacturers have developed vacuum defoaming technology and dynamic mixing heads, which can increase the yield rate to over 99% by eliminating gases in the raw materials and optimizing the flow channel design. A more advanced closed-loop control system can monitor injection pressure and temperature in real time, ensuring consistent physical performance of each product.

With the integration of 3D printing technology, the manufacturing boundary of liquid silicone rubber is further expanded. The photopolymerization LSR printing technology has been able to manufacture complex hollow structures, opening up new paths for customized medical implants and microfluidic devices. This technological revolution proves that when material properties are deeply integrated with engineering technology, soft silicone rubber can also create the hard core strength of industrial manufacturing.
