S? THREADED INSERTS FOR PLASTICS
? SI in serts are typically specified in applicati ons where strong, durable metal threads are required in plastic material, especially where freque nt assembly and disassembly of the unit for service or repair is n ecessary.
? Applicati ons for ?Sproducts in clude: computers and term inal boards, automotive, electr onic equipme nt, bus in ess mach in es, aerospace, com muni cati ons equipme nt and in strume nt cases.
? SI in serts are available in brass, sta ini ess steel and alu minum.
? SI inserts are available in a large variety of ultrasonic / heat stak ing, molded-i n or press-i n types.
? SI in serts meet the strictest quality guideli nes which are maintained through in-process audits and adhere nee to the ISO 9001 and QS-9000 discipli nes.
ULTRASONIC / HEAT STAKING INSERTS
? Ultras onic - In stalled by press ing the insert into the moun ti ng hole with ultras onic insertion equipme nt while simulta neously applying a high frequency vibration. Frictional heat caused by the vibrati on melts the plastic surro unding the insert allow ing easy insertion. When the vibration ceases, the plastic solidifies, locking the insert perma nen tly in place.
? Heat Stak ing - In stalled by press ing the insert into the moun ti ng hole with a thermal press to melt the plastic surrounding the in sert.
MOLDED-IN INSERTS
In stalled duri ng the moldi ng process, the in serts are located in the mold cavity by core pins. When the mold ope ns, the core pi ns are withdraw n leavi ng the in serts perma nen tly en capsulated in the plastic secti on with only the threads exposed.
