With industrial injection molding, Proto-Cast LLC can help you solve part problems, from weight reduction to elemental resistance. We have been helping companies create unique, durable parts for over 50 years. Today we will look at 3 examples of how industrial injection molding created successful parts. Case Study #1: Smooth Sailing A manufacturer came to… Read More ➝
There are three main ways to join plastic parts: mechanical, adhesives, and welding. Mechanical processes – such as screws, rivets and snap-fit – are perfect for products that will need to be disassembled during their lifetime or for low-volume runs. Adhesives – such as glue – form a more permanent bond and are great at… Read More ➝
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 ➝
“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 ➝
