Heat insertion is the process which finds applications in joining plastic parts. Thermoplastic parts as such are too soft to sufficiently hold threads and offer tight joints. To overcome this problem threaded inserts of brass or steel are added post molding. For heat insertion the brass or steel part to be inserted is preheated to temperature specific to the part and then pressed in the hole on the plastic part, which results in melting of plastic in the narrow zone, which flows in the knurls provided on the insert. The plastic is re-solidified by cooling, completing the assembly which results in much better mechanical properties.
