Inter-mold^® technology

Implementation

Material Specifications

The inter-mold^® technology is intended for injection molded parts and can be used with a wide range of plastic resins such as:

• Polypropylene (PP)
• Polyethylene (HDPE and LDPE)
• Polyacetal (POM)
• Nylon (PA6 and PA6.6)
• Thermoplastic elastomers

Technical overview

The inter-mold® process is not an insert molding process. It is the process to mold hooks during a standard injection cycle (one-shot) so that they are integrally part of a product - similar to a rib.

This is made possible by using a specifically designed insert that is mounted into the injection mold. Hook shapes are pre-machined in the insert to enable hook formation. During the ejection process the hooks temporarily straighten in order to be demolded. After demolding, the hooks take their original shape.

Implementation

• Molds are modified to contain proprietary inserts.
• Slides and retractable inserts are available for draft angles beyond 45°.

Current projects show that the inter-mold® technology is reliable for the production of millions of parts without specific maintenance!
