Silicon Rubber Extruders and Injection molding Screw barrel are optimized for the production of best quality silicone products.
silicone rubber can be found in a wide variety of products, including: voltage line insulators, automotive applications; cooking, baking, and food storage products; apparel such as undergarments, sportswear, and footwear; electronics; medical devices and implants; and in home repair and hardware with products such as silicone sealants.
Liquid Injection Molded Silicone (LIM), Liquid Silicone Rubber (LSR) Molding.
Moulded parts made from liquid silicone (LSR) or solid silicone (HTV) are extremely elastic, odourless and tasteless, chemical, UV, ageing and temperature resistant. Numerous fields of application are opened up for those who have mastered the processing methods. Our systems solutions offer you the best possible basis.
LSR & LIM
Single And Twin Screw available for this product
At Raj engineering works we offer a complete injections crew barrel solution for liquid silicone rubber (LSR) molding that meets the special mixing and metering requirements of low-viscosity thermoset ingredients. Our screw barrel can be retrofitted on standard injection molding machines. Our service includes a specially designed screw, barrel, seal, valve, and nozzle, along with other components where needed, such as a feed-pipe adapter.
Our Highly precised zero tolerance (0.1) and fair price policy make us the most reliable screw barrel manufacturer for silicone processing industry.
