Product Introduction
Silicone Plunger is also called Rubber Piston, Silicone Lip Seal or Silicone Rotary Seal, which is used in cylinder products or reciprocating seal devices and will rotate when device working. Rubber Plunger Seal cross section seems Y shaped, which is for sealing, rotating and pressure working.
Product Specifications
Silicone Plunger & Lip Seal is used in reciprocating seal devices, which has a longer life span than Silicone Rubber O ring.
Silicone Plunger & Lip Seal Working speed ranges vary in different materials
| Working pressure | < 25 MPa |
| Working temperature | -40~+120℃ |
| Medium | hydraulic oil, water, air |
| NBR | 0.01~0.6 m/s |
| FKM | 0.05~0.3 m/s |
| PU rubber | 0.01~1 m/s |
Lip ring made of PU rubber is better in sealing, life span and working pressure limit without retain ring. |
Product Pictures
Silicone Plunger is made from high grade silicone, liquid silicone rubber ( LSR ) because it is better in sealing, life span and working pressure limit without retain ring compared with other rubber plungers seal, which are mainly made of NBR or PU rubber.
Silicone Plunger & Lip Seal is mainly made by silicone rubber compression mold tooling or LSR injection molding ( LIM ) with middle mold plates.
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.
Silicone Plunger & Lip Seal properties:
Excellent sealing
Less friction and smooth movement
Good pressure resistance and wide applicable pressure range
Simple structure and low cost
Easy installation
Our Company
Xiamen Juguangli Import and Export Co.,Ltd, not only can make rubber compression tooling & plastic injection molding, produce silicone rubber compression parts & products, but also can make liquid silicone rubber injection mold and produce liquid silicone products.
Four production plants: Mold-Making Plants, Silicone Rubber Compression Plant, Plastic Injection Plant, Liquid Silicone Rubber Injection Plant
At the beginning, our company only have basic and good CNC, EDM, Grinder, Milling machines etc. For better mold quality, we also have one imported precisely high speed CNC, two mirror EDM, one precision Grinder and related test device now.
Compression silicon rubber molded parts tolerance, can up to +/- 0.02mm, like for medical device, smart cell phone, electronic and so on.
Our company not only can produce normal precision liquid silicone rubber products, but also can make metal + liquid silicone & plastic + liquid silicone rubber over-molding products.
Our Quality Speaks for Us
Different from counterparts, our company prefer to produce and offer qualified product at reasonable price, rather than produced by second-class materials and save deserved mold-making process, even at the expense of loss orders.
Please believe: What Price, What Goods.
We are a professional silicone product manufacturing factory, with more than 15 years of experience in silicone rubber production, advanced equipment, process specifications, can customize a variety of silicone products for you, such as silicone rubber buttons, sealing rings, gaskets, ring, etc., welcome to contact us for inquiry at any time.
