In recent years, the molding process technologies for liquid silicone rubber (LSR) have undergone continuous iteration and upgrading. New processes such as low-viscosity rapid curing and high-precision injection molding are gradually becoming widespread, helping downstream manufacturers significantly improve production efficiency and reduce material waste during production.

Traditional silicone rubber products have mostly been produced using compression molding, which involves long production cycles and requires extensive manual deflashing and post-processing, resulting in relatively low efficiency. In contrast, the new generation of LSR molding processes employs two-component room-temperature or medium-temperature rapid-curing systems. After mixing, the raw materials can be directly injected into molds and complete curing within minutes, eliminating the need for prolonged high-temperature vulcanization and significantly shortening production cycles. At the same time, LSR exhibits excellent flowability, allowing it to naturally fill fine gaps in molds. The resulting products have higher dimensional accuracy and smoother surfaces, requiring little to no post-processing, thereby greatly reducing manual labor.

For different application scenarios—such as coating, potting, and mold making—the industry has also developed corresponding specialized processes. In electronic coating applications, automated spraying processes allow LSR to be uniformly applied onto circuit board surfaces, forming an ultra-thin protective layer with uniform thickness, at production speeds several times faster than traditional manual brushing. In potting applications, vacuum potting processes thoroughly remove bubbles from the compound, preventing voids inside potted components and ensuring consistent protective performance. In mold-making applications, silicone is directly poured after vacuum degassing, producing molds free from bubble defects and significantly extending their service life.

During our product formulation design phase, we fully consider the actual production process requirements of downstream customers, optimizing parameters such as viscosity, curing speed, and working time for different scenarios, so that products can be better adapted to automated production equipment. Going forward, we will continue to collaborate with downstream customers on process co-optimization, helping them further improve production efficiency and reduce overall production costs.
