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 with metal or plastic inserts.
In Insert molding, a metal part is ‘inserted’ into the mold prior to injections of rubber. This produces a finished rubber + 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 & control, diaphragm and general fluid control applications. The tools are reusable so molding can produce economical part prices for low and high volume programs.
