Automatic Molding

Our automatic molding department provides 60 - 80% of the feedstock to the rest of the facility.  This department provides molded tube stock to the CNC and automatic slicing departments.  Through the automatic molding process we are able to produce sleeve stock of exacting size with virgin PTFE and all the various common and exotic filled compounds which are utilized within our industry.

To achieve optimum efficiency and accuracy, our automatic presses are custom built to Prolon's specifications.  They range in size from one to twenty tons and can produce up to 7.5" diameter pre-forms.

Once molded, the pre-forms head to our sintering department where the microporcessor controlled ovens are programmed to cure our products with extreme accuracy.  This produces a stress relieved pre-form which is now ready for either the maching or auto- cutting departments.
