conductive PU coatings Back Lighting industrial instrumentation and communications equipment molding processes custom made silicone button

for gun sights and accessories

keypads are used in a wide range of applications including medical, industrial, instrumentation and communications equipment.

The Application Guide includes:

• Material and Processes
• Mechanical Tolerances
• Design Recommendations

Silicone material is supplied to the keypad industry in two forms, liquid and gumstock. Liquid silicone is a two part system mixed as it is used; gumstock is a one part system that has a shelf life. Both are heat cured. Liquid 

silicone has the consistency of vaseline while gumstock is more like putty or clay. Silicone is measured for 

hardness in a shore A scale. The lower the number, the more silicone there is in the product and the softer it feels.

 The higher the numbers the less silicone and the more filler there is in the product and the harder it feels. 

Fillers can reduce elongation, compression set, tear and tensile strength.

There are less than a half dozen manufacturers of silicone. Anconn uses Dow and GE materials because 

of their UL listing, six sigma quality rating for consistency and traceability of material batch runs.

Molding silicone rubber varies by process. The tools themselves are very similar and are usually made 

from P20 steel or 6061 aluminum. 

The types of molding processes are liquid, compression, transfer and extruding. Liquid molding is a closed 

loop system and molded under pressure using computer controlled repeatable equipment.

What we can do

Shenzhen Anconn Rubber & Plastic Industrial Limited, is a reliable silicone, rubber, and plastic manufacturer in China, Specialized in silicone/rubber stoppers, silicone/rubber tubes, rubber feet, silicone keypads, rubber handles, suction cups, grommets, seals, O rings, protective covers, rubber mounts, rubber foam items, EVA foam items , plastic parts and other various items, in our company you can find the products to satisfy your various demands.

Since establishment in 2014(we have in this field for 15 years), we devoted ourselves to produce high quality rubber and plastic products, which was realized by adopting best raw materials (meet SGS, Rohs, FDA and Reach standards), strict production processes, and continuous R & D investment.

When other companies are doing trade business, we don’t follow, we have our own factory to produce molds and products, we don’t produce molds and products by third parties. We are factory, which direct to customers, this is our advantages. We also have an engineer team which can support our customers who can not offer 2D or 3D drawings. We offer fast services and more advantage prices to support and help your customers.

What is our consistent adherence ?

“ Quality first & considerate service” is never a decorative slogan in Anconn, this is the conduct code throughout every aspect of each Anconn staff’s daily work. We focus on what customers really concern.

May be you have some questions

1)Where is the rubber comes from ?
rubber comes from a milky white juice which some trees and plants have instead of sap. This liquid, called latex, can be found in the roots, stems, branches, bark, leaves, and fruit of over 400 different plants. Most latex, however, comes from the inner bark of the hevea, or rubber tree
To get the latex, workers cut narrow slits in the bark of the rubber tree at daybreak, for the latex flows easily when the air is still cool. The latex is then allowed to drip into cups attached to the tree for three hours.

The latex, which is 2/3 water, is then taken to a rubber factory quickly, for it spoils easily. There, it is heated and mixed with acid. This process causes the latex to coagulate, or form solid curds. These curds are crude rubber.

2)What are the colors your factory can make ?
We can make any colors on the pantone cards, what’s you should do is telling me the color numbers you want, then our factory will match the colors for you according to your requirements.

3)How can you make sure the dimensions are correct of the products ?
We have thickness gauges, hardness testers, callipers, tension testers and other instruments to make sure each parts of your products are correct, also we use our CNC machines to produce molds, the precision can reach to 0.01 mm.

4)Can your factory delivery goods on time ?

Yes, we have a very big mold factory, we have 30 Machines and 20 technical staffs to make molds, So we can finish your mold within 5 days after receiving your deposit.

We have 50 general workers to produce products after molds are ready, they work 3 shifts, it is never stop to produce products, so we are confident to finish any order on time.

5) Types and properties of rubber

There are many types of rubber, each with special properties: 
Neoprene Rubber - Good weatherability and resistance to abrasion.

Buna-N Rubber - Resists oil and solvents. Not as weather resistant. Also called nitrile, acrylonitrile, and NBR.

Silicone Rubber - Good flexibility and resistance to ozone, sunlight, and oxidation. Very good electrical insulator. Also called polysiloxane.

EPDM Rubber - Excellent for outdoor use.

Natural Gum Rubber - Superior resilience, tensile strength, elasticity, and abrasion resistance.

Fluoro rubber - Resists corrosive environments, with exceptional resistance to heat, aging, weather, ozone, oxygen, and sunlight, plus fuels, solvents, and chemicals. Good flame resistance. Also called FKM.

Natural Latex Rubber - Ultra-elastic has excellent strength and stretchability. Has exceptional tear resistance.

SBR Rubber - Has good abrasion and wear resistance. Also called styrene butadiene.

Vinyl Rubber - Good resistance to water, chemicals, and weathering. Also called polyvinyl chloride (PVC).

Santoprene Rubber - Combines the characteristics of rubber and plastic to produce a material that offers excellent weatherability and chemical resistance.

ECH Rubber - Excellent resistance to fuel, oil, and ozone. Also called epichlorohydrin.

Butyl Rubber - Nearly air and gas tight. Has good weatherability, oxidation resistance, and electrical resistance. Excellent resistance to alkalies and acids. Often used for inner tubes. Also called isobutylene isoprene.

Latex-Free TPE Rubber - Transparent elastomer with gel-like consistency to absorb vibration and conform to irregular surfaces. Super stretchy. Has great tensile strength. This type of rubber is nontoxic and nonallergenic.

Hypalon Rubber - Superior weatherability and resistance to ozone, chemicals, and oil even at high temperatures. Resists flex cracking and abrasion from weather, heat, and chemical exposure. Low water absorption. Also called chlorosulfonated polyethylene.
