As mentioned earlier, TPE is an ideal material for creating a soft, non-slip grip. This is especially useful for products requiring tactile sensitivity, such as medical products, surgical instruments, and other handheld devices.

Increasingly popular with manufacturers of consumer products, medical devices, and portable devices, plastic overmolding improves functionality, performance, and aesthetics.

The plastic overmolding process may be a great option for your next project after you consider the significant advantages it provides.

For over twenty years Custom Plastics & Innovations Inc. (CPI) has worked with many industries and sectoral groups including the automotive, electronics, medical, bio-tech, consumer products, business machines and industrial products. We are a single-source supplier of molds and plastic parts to the manufacturing sector.

It typically includes a rigid, plastic-base component overlaid with a thin, pliable, rubber-like thermoplastic elastomer (TPE) exterior layer or other materials using either a single-shot (insert molding) or two-shot (multiple-shot molding) technique.

Fiberglass molding is a method for forming complex and intricate parts using fiberglass resin. Though there are several reasons for producing parts and components from fiberglass, the most pressing reasons are the...

Overmolding plastic also lowers production costs as it improves product viability and customer satisfaction. It’s easy to see why manufacturers are so drawn to overmolding.

Plastic coating is the application of liquid polymers or plastic onto the surface of a workpiece through dipping/immersion. The result is a thick plastic finish for protective and decorative purposes. This gives the material additional...

Polyurethane molding is the process of fabricating or manufacturing plastic parts by introducing a urethane polymer system into a tool or mold and allowing it to cure. Like any other type of plastic, the excellent processability...

Overmolding plastic is appropriate for so many applications. Yet, several factors must be considered before determining if it’s the best solution for your project:

Blow molding is a type of plastic forming process for creating hollow plastic products made from thermoplastic materials. The process involves heating and inflating a plastic tube known as a parison or preform. The parison is placed between two dies that contain the desired shape of the product...

Thermoforming is the process of heating thin plastic sheets to its forming temperature and stretching it over a mold which takes its shape. After cooling and setting of the molded plastic sheet, each part will be separated from its batch to form a single unit or product...

Partnering with an experienced custom injection molder — especially one with scientific molding expertise, such as Kaysun — helps you navigate the pros and cons of using overmolding on your project. The right partner collaboratively guides you to the best decision for your application and bottom line.

Plus, a TPE surface acts as an environmental barrier, protecting a product and extending its life by reducing shock, vibration, and noise — all key benefits of the overmolding process.

Overmolding is a unique custom injection molding process that results in a seamless combination of multiple materials into a single part or product.

Plastic fabrication is the process of designing, manufacturing, and assembling a product made out of plastic material or composites that contain plastic. There are numerous plastic fabrication methods known today, considering the...

Overmolding is a rare process that adds advantages in several ways (see list above) and also lowers production costs. How? Overmolding reduces the number of manufacturing steps needed.

Overmolding helps a product stand out from the competition. TPE not only creates a visually attractive surface, it comes in a wide range of colors and can be engineered for different finishes.

Closed cell foam is a type of foam where the “cells” are tightly pressed together and enclosed. It contrasts open cell foam, such as polyurethane, with interconnected open cells. With closed-cell foam, because none of the cells...

Plastic injection molding, or commonly referred to as injection molding, is a manufacturing process used in the mass fabrication of plastic parts. It involves an injection of molten plastic material into the mold where it cools and...

Imagine a clear TPE surface carrying a corporate logo, message, or operation instructions. These can also be overmolded on patterned or customized substrates.

Rotational molding, commonly referred to as "rotomolding", is a plastic casting technique used to produce hollow, seamless, and double-walled parts. It uses a hollow mold tool wherein the thermoplastic powdered resin is heated while being rotated and cooled to solidify...

In the automotive market, for example, overmolding eliminates the need for injection molding and assembly for components (such as gaskets or bumpers), as well as secondary finishing operations (priming, painting, or coating).

From selecting materials to handling high volumes to producing high-quality parts, the overmolding process requires special skills and experience.
