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.
