Rubber Molded Parts
Rubber molding is a molding process that is characterized by forcing hot rubber material under pressure into a mold cavity. The mold cavity is created using two steel dies, which have been machined into shape. Depending on the material and geometry of the finished part, a compression or injection process can be used. We also offer rubber molded parts with metal or plastic inserts.
In insert molding, a metal part is “inserted” into the mold before the rubber or metal injection molding process. This produces a finished rubber and metal part with higher strength than a 100% rubber part. The metal insert part is typically produced by machining, powder metal, or the casting process.
Understanding the Benefits
A primary advantage of the rubber molding process is the ability to inexpensively produce flexible parts for sealing, vibration dampening and control, diaphragm, and general fluid control applications. The tools are reusable so that molding can produce economical part prices for low and high volume programs.
