Tight Tolerance Rubber Sheet

Tolerances because of the nature of rubber and other flexible materials tolerances need to be looser than sheet metal tolerances.

Tight tolerance rubber sheet.

With thousands of sheet rubber formulations you can order the materials you need for any environment or application including products that meet dod and military ams astm nse nsf fda and many more. Tight tolerance hardened multipurpose 4140 alloy steel sheets and bars. These sheets and bars are hardened for increased abrasion and impact resistance. That s because rubber is more sensitive to environmental conditions such as heat cold and humidity.

Tight tolerances custom widths thicknesses and lengths 031 and thinner 010 032 to 061 012 062 to 124 016 125 to 186 020 187 to 374 031 375 to 500 047 501 to 750 094 751 and thicker 10 sheet rubber thickness tolerance. Fabric reinforced high temperaturesilicone rubber sheets and strips. However very tight tolerances can also be met. All of our rubber sheeting products meet rma standard specifications.

One layer of fiberglass cloth is inserted between two layers of silicone rubber to give these sheets and strips the strength to stand up to high stress and flex. Rubber tolerances rubber tolerances all the good stuff about rubber its flexibility elasticity its malleability and fact that the material can flow into complex unusual shapes during moulding also means that it is inevitably more difficult to control than other materials. Relatively new liquid silicone rubber sheet lsr is cast and cured into thin gauge continuous rolls from 010 to 032 thick in 36 widths. It is available with a base plate or strip gauge to cut strips with a tight tolerance.

The most commonly available lsr sheet materials are provided in 10 to 40 durometer shore a. Because metal parts support tight tolerances it s assumed incorrectly that rubber also supports a high degree of precision. Rubber has many useful properties but it can t match metal s tolerances. These are helpful when designing and producing a part.

The rubber slitter is designed to cut very dense rubber and plastic sheeting. Also known as flat stock the thickness on these sheets and bars is held to a tight tolerance. Lsr compounds have a platinum cure system which decreases out gassing and makes these silicone products more friendly to electronic medical and optical applications. Hardened multipurpose 4140 alloy steel bars.

Model rs2 is equipped with a high torque motor and is designed with a very low knife speed to keep friction and heat build up to a minimum. The rubber manufacturers association rma has developed tolerance tables with ranges to provide communication between user and provider across a wide range of industries. Parts requiring extremely tight tolerances may need class a hardened steel tooling or water jet cutting vs.
