Advancements in polymers in recent years are expanding the capacities of cooking appliances. Lightweight, tough plastics are catching up to the dishwasher durability and surface integrity of glass, but are consumers ready to pay more for it?
Cost modeling is the practice of understanding the cost structure of the products purchased or manufactured for the purpose of optimizing a design or supply chain. The cost modeling process is focused on supporting three business areas: target costing, procurement, and competitive analysis.
Aerospace and automotive manufacturers have been incorporating hybrid joining into their production for years now. This joining method, however, has been largely ignored by appliance manufacturers. A novel approach to assembly construction, the method is surely applicable within the appliance industry - and stands to benefit both appliance manufacturers and end users.
Residential gas water heaters have long been considered safe when properly used. Yet the potential dangers resulting from the improper use and storage of gasoline and other flammable materials in the vicinity of the water heater have continued to be a concern among manufacturers of residential gas water heaters.
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.
