Why 3ERP is your best option for plastic injection molding

Overmolding uses injection molding to create a part from multiple materials. This process adds an injection-molded layer of material over an existing injection-molded workpiece. The overmolding process produces chemically bonded parts made using multiple materials.

Overmolding

Overmolding uses injection molding to create a part from multiple materials. This process adds an injection-molded layer of material over an existing injection-molded workpiece. The overmolding process produces chemically bonded parts made using multiple materials.
The overmolding method is often cheaper and more effective than other manufacturing approaches that require creating and assembling component material parts separately. The process can also be used to build layered parts from scratch or to add a resistant outer layer to existing plastic parts and tools, providing a more rugged exterior. Toothbrushes consisting of a solid plastic body and rubberized grip are a common example of an overmolded product.

Insert Molding

Insert molding is similar to overmolding, but the substrate is not necessarily plastic and does not have to be produced via injection molding. For example, insert molding can be used to add a plastic coating to a pre-fabricated metal part.
Common parts made by insert molding include sharp handheld tools, such as scalpels, which consist of a metal blade partially housed within a plastic handle. Insert molding is also frequently used to create products that incorporate bushings, clips, and fasteners

From industrial gaskets to the soles of your shoes, elastomeric parts are both ubiquitous and unique. Made from elastomers, a group of rubber-like polymers, these flexible, stretchy, and shock-absorbing components are easy to make — and can be produced in several ways.

One of the ways to produce elastomeric parts is injection molding. Not the injection molding of thermoplastics, but the injection molding of thermosets like liquid silicone rubber: this material is injected in its liquid state then cured to make it solid. But today there’s a great alternative to liquid silicone injection molding, and that’s the 3D printing of flexible materials like TPE and TPU. No longer specialty materials, TPE and TPU can now be 3D printed on low-cost FDM printers.

This article looks at the basics of elastomeric parts: their properties, their applications, and whether you should opt for injection molding or 3D printing.

What is an elastomer?

An elastomer is defined as a polymer with a low Young’s modulus, a high failure strain, and viscoelasticity — a combination of viscosity and elasticity. Sometimes referred to simply as rubbers, elastomers are actually a broader category that includes non-vulcanized materials.

In layman’s terms, elastomers (elastic polymers) are materials that are, to various extents, elastic, stretchy, flexible, or deformable at room temperature. This is due to their weak intermolecular bonds. All of this makes elastomers incredibly useful. Since they can be bent and stretched without breaking, they are used in many applications where a more rigid material would fail in its purpose.
