Rubber Washer, known as silicone rubber seal, silicone rubber
gasket, silicone rubber sheet etc, which can be categories into
rubber plate washer, rubber O ring washer, rubber belleville
washer, rubber spherical washer, rubber shoulder washer etc, and
made of elastomeric silicone rubber like neoprene, VMQ, EPDM,
Viton, Liquid silicone rubber etc. Washer is also made of plastic,
metal, copper. Some washers made of rubber plastic overmolding
washer, rubber metal overmolding washers, liquid silicone rubber
overmolding washer, rubber backed adhesive washer etc.
Rubber Backed Adhesive washer is also called 3M backed adhesive
tape + silicone rubber washer
Silicone Rubber 3M Tape Adhesive Backed Washer
Silicone 3M Tape Gasket is in aim to improve the water-proof and
dust proof function of electronic products. Generally using IPxx
code to identify the waterproof grade and anti-dust grade. Such as
IP 55, IP56, IP57, IP 65, IP66, IP67 etc.

Silicone 3M Tape Gasket Main Applications
The application of Silicone 3M Tape Gasket is rapidly growing in
the industrial manufacturing market. Such as Smart Phone products,
Electronic Products, Medical Products, etc.
Silicone 3M Tape Gasket Technological Processes
1. Making Mold Tooling first
2. After finishing mold, producing silicone rubber samples (about
5-10 molds) for test.
Test each cavity silicone rubber sample by 3D projectors if
dimensions are within tolerances. Some precision samples need to
cut (cutting cross section) which is easy to test the sizes and
designs.
3. If dimensions are ok, sending the whole piece of silicone
products to factory for dealing with silicone glue.
Notes:
1. If big silicone rubber products, burring firstly, and then deal
with silicone glue.
If small silicone rubber parts, generally dealing with silicone
glue firstly, and then choose fixture tooling (cutting/punching
die) to burring. Or removing the big barbs, and then deal with the
silicone glue, finally fixture tooling (cutting/punching die) to
burring.
Silicone 3M Tape Process
1. Paste double sided silicone 3m tape with the anti-adhesive sides
of anti-adhesive paper;
2. Cutting the inner round holes by cutting die;
3. Silicone products are coated with silica gel treatment agent;
(Notes: silica gel treatment agent should be even/
well-distributed; and should not coat on the surface of
silicone products)
4. Rightly placed stick double sides silicone 3m tape, the surface
of 3m tepe should be even. (Notes: should not be a little off; and
should not have bubble.)
5. Next Die Cutting for burring
6. After finishing die cutting, check if have less materials or not
clear cutting.
7. Test the finished products by 3D projects and amplification
instrument
8. Before packaging, check the silicone glue one by one.
