LSR Plunger Seal by Silicone Injection Molding
LSR Plunger Seal is made of liquid silicone rubber ( LSR ), Medical Grade Silicone and FDA Grade Liquid Silicone Rubber by Silicone Injection Molding.
LSR Plunger Seal have better sealing performance, life span compared with other rubber plungers seal, which are mainly made of NBR or PU rubber.
Liquid Silicone Rubber Plunger & Lip Seal is mainly made by LSR injection molding ( LIM ) with middle mold plates, which will have good parting line and small rubber flashing or the product.
Silicone Plunger Seal 's margin & edge should not have silicone rubber flashing ( burrs ) because it will rotate when device is working. For sealing function, silicone plunger seal 's design and sizes telorance have higher demands, especially for seal edge.
Middle mold plates are chamfer processed by cutting tool, which will wear out with processing. In aim for deserved silicone plunger seal 's designs and sizes, the cutting tool needs to be changed frequently after a short-time processing.
LSR Injection molding problems occurs during production. To stop production to fix problems and retooling is timing consuming and very expensive. Xiamen Better Silicone can optimize the tool design and identify potential problems before cutting the steel and can help reduce some of these problems.
