What goes into injection molding cooling time?

Part design, material selection, mold design and processing all play a role when it comes to injection molding cooling time. Jeremy Williams, RJG Here’s a value that probably sticks out in your mind if you’ve been to an RJG training event: 80%. That’s how much of the molding cycle is spent cooling the plastic part

Overmolding: 2 types to know

MTD Micromolding Some micro projects require specialty micro injection molding processes, such as overmolding. Overmolding involves two or more materials molded together to become one part. Examples include molding plastic over plastic or molding plastic over a preformed part, such as a metal insert. (See examples of common polymers and substrates below.) MTD specializes in

5 things you need to know about rapid injection molding

Here are five things you should consider when deciding to use rapid injection molding as part of your development process. Roger Spurrell, Vaupell Rapid Solutions A every custom injection molder will tell you, “There’s no such thing as an easy part.” When you add in the need for speed the trade-offs start to multiply, because

Expanding design horizons with gas-assist molding

Gas-assist molding, the process of using nitrogen gas pressure to fully form a part, increases design and manufacturing options for injection molded components. Scott Rishell, Mack Molding Traditional plastic processing brings design and manufacturing benefits through repeatable, high-volume and high-quality part production coupled with cost reductions, but its versatility can be expanded in certain scenarios

What is micromolding?

Micromolding is a very specialized art form. It is the tiny-scale molding form of injection molding that entails building a cavity to match the shape of the part you want to make, sort of like the plastic molding that makes Lego bricks. Very small, high precision plastic molding goes into micromolding for medical devices, according
