How glass transition temperature defines the upper thermal limit of injection molded plastics — and why it matters for material selection, mold design, and part performance. Glass transition temperature (Tg) is the temperature at which an amorphous thermoplastic transitions from a hard, glassy state to a soft, rubbery one. Below Tg, the polymer chains are […]

What V-0, V-1, V-2, HB, and 5V mean for injection molded plastic parts — and how to specify the right rating for your application. UL 94 is the standard for flammability testing of plastic materials for parts in devices and appliances, published by Underwriters Laboratories. It classifies plastics by how they respond to a standardized

Material selection is the most consequential design decision in injection molding, whether you are producing consumer products or precision industrial parts. The wrong material produces a part that fails in service, absorbs moisture and loses its dimensions, cracks under chemical exposure, or costs twice what was budgeted. The right material does the opposite: it makes

Metal injection molding (MIM) is a manufacturing process that combines the geometric freedom of plastic injection molding with the material properties of metal. In this specialized molding process, fine metal powder is mixed with a thermoplastic binder to create a feedstock that processes through standard injection molding equipment. The molded part — called a green

Material properties, processing requirements, design guidelines, and applications for ABS injection molding — one of the most common injection molding plastics. ABS (acrylonitrile butadiene styrene) is the most widely used engineering thermoplastic in injection molding. It is not a single material but a versatile terpolymer whose three components each contribute distinct properties: acrylonitrile adds chemical

A practical guide for engineers, product teams, and purchasing professionals specifying polycarbonate injection molded parts. Polycarbonate, often abbreviated as PC, is one of the most widely used engineering thermoplastics in injection molding. It is valued for a combination of properties that few plastics match at the same time: exceptional impact strength, high optical clarity, dimensional

How the overmolding process works, which material combinations bond, and the design rules that determine whether your overmolded part succeeds or fails. Overmolding is an injection molding process that produces a single part from two different materials by molding the second material directly over the first. The result is a multi-material part — a rigid

A practical guide for engineers and product teams. Rapid injection molding delivers real injection molded plastic parts in days to weeks, often making molded parts available earlier than full production steel tooling. It uses the same injection molding process and the same thermoplastic materials as production molding, but the tooling is made faster — typically
