Forming Rubber

Forming Rubber

Mosites #651 is specially compounded for optimum performance in forming rubber applications.  These operations include but are not limited to bladder hydro-forming, hydro-presses, fluid forming, diaphragm forming, bulge forming, drop hammer and metal spinning.

Compounded with ingredients that give it exceptional forming characteristics and slickness for good release, #651 is equally suited for hot and cold forming.  It is cream colored so it will not mark parts.  It performs just as well as a throw sheet as it does as a platen rubber.  It is available in a variety of hardnesses to accommodate all types and thicknesses of metal.

Mosites #651 Wear Pads are an industry standard when it comes to forming operations.  Available in hardness of 50 durometer to 90 durometer and numerous diameter and shaped pad sizes.  A large number of stock sizes are available.  Custom molded sizes available on request.

Mosites #651 Tray Pads were developed to serve as a protective bladder or diaphragm in hydraulic fluid presses.  It is typically sold in roll sheet .5” to .625” thick  by 48” wide by 120” to 160”.  Available with wedge shaped inserts installed at one end to facilitate winding the sheet on a carriage drum.  Its primary function is to protect the main bladder from the possibility of punctures from sharp tool edges.

Mosites #796 Drop Hammer Rubber is a semi-cured rubber sheet used in drop hammer applications.  This compound flows uniformly under pressure to prevent chatter marks on the metal blank.  It has just enough resilience to return to its original shape for reuse.
