Thread-lockers keep fasteners from loosening due to vibration. Here are insights into how, why and when to use fasteners with preapplied thread-lockers.
American Stove Parts (Temecula, CA) manufactures components for gas cook stoves, including fil-ters, tube assemblies, injection molded components, valves, fittings, door gaskets and burner knobs.
Molten zinc alloy is not commonly considered as
an instant curing “glue,” nor as an alternative to instant-cure adhesives for
bonding small components. But it has been used for more than 60 years in
FisherTech’s Injected Metal Assembly (IMA) process to join components in much
the same way as adhesives. While zinc alloy can’t replace adhesives in all
applications, it can do so in many assemblies without the problems of peeling
and thermal degradation inherent with conventional adhesives, and without the
need for special surface preparation.
There are many critical plastic-part assembly
applications where the long-term integrity of the joint is absolutely
essential, such as when the assembly must contain a liquid. Examples include
various small household appliances, oral hygiene appliances, or parts for major
appliances, such as a dishwasher arm or clothes washer pump assembly.
Combining materials of choice is important for the appliance industry where “form follows function” is archetypal. Appearance, performance, cost, and assembly ease constantly dog the engineering community in this industry. This is particularly true when joining dissimilar materials, such as metals and plastics, into one unit or subassembly.
When an application requires two thin metal sheets to be joined permanently face-to-face, designers routinely have turned to rivets, welding, or adhesives and tapes. But tradeoffs loom with each of these methods. An innovative fastener design using clinch technology provides a more practical and less complicated joining method that is able to perform multiple functions and expand design possibilities.
