Often our clients bring us projects that involve combining a variety of plastic and metal components. Traditionally, this was achieved through additional secondary services or more complex assemblies. But with the advent of insert molding and its counterpart, overmolding, it is now easier, faster, and cheaper to create complex finished projects. What is Insert Molding?
Thermoplastic resins are a popular choice for most injection molding projects. Unlike thermoset resins, thermoplastics do not create permanent bonds as they cool. This means they can be reheated and reprocessed multiple times before their properties begin to degrade. Thermoplastic resins are still durable, elastic, highly flexible and versatile, but they can easily be recycled… Read More ➝
ABS (Acrylonitrile Butadiene Styrene) is one of the most widely used polymers in injection molding. The styrene content gives it a shiny, impervious surface, and the polybutadiene provides excellent toughness, even at low temperatures. The chemical structure of ABS also allows it to be modified to improve certain characteristics depending on the application at hand…. Read More ➝
“What is the difference between plastic injection molding thermoplastic and thermoset polymers?” This is a question our customers often ask, so today we are taking a closer look at the subject. As the prefix “thermo” suggests, the differences in these polymers lie in how they react when exposed to heat. While both thermoset and thermoplastic… Read More ➝
At Proto-Cast, LLC, some of our most long-standing clients are in the aerospace industry. From turbine blades and housings to panels and chassis components, we can accommodate the low volume injection moldingnecessitated by these highly customized parts. Sometimes referred to as “bridge manufacturing,” low volume injection molding covers quantities from 50 to 100,000. When used… Read More ➝
