Lathe cut rubber can produce high quality seals, gaskets, washers, spacers and hose at an affordable price. Once the proper rubber has been selected it is then milled and extruded into the basic rough shape. The material is then loaded onto a sized mandrel and wrapped which applies even pressure to the rubber over the mandrel. From here the whole unit is placed inside an auto-clave for curing. After being removed from the oven the roll or tube is stripped of the wrapping material and removed from the mandrel. The tube is then loaded onto another sized mandrel and placed into a lathe or grinder this process reduces the material down to the correct depth or wall and also establishes the desired finish. The tube is again removed from the mandrel, placed onto a cutting mandrel and loaded into a cutter.
The cutter is set to produce the precise individual parts. These parts can be cut square with flat edges or can be angle cut to become a chamfer, angular or V-groove seal. The rubber can also be thin square cut for use as a gasket, or cut to length as a rubber tube or hose. This process is very precise to allow for tight tolerances and easily reproducible for large runs. We also accommodate short part runs so be sure and contact us today, or click through to our quote request page.
