Injection molding materials

Below are some of the most popular injection molding materials:

Polyethylene

It’s commonly used to make plastic bags for consumer goods, including milk, detergent, and medicine bottles. Polyethylene is a popular molding material because it’s lightweight, chemical resistant, strong, and for its electrically insulating properties.

Polycarbonate

Used to produce clear or transparent plastic parts. It’s ideal if you require a stronger injection molding resin than acrylic.

Acrylic

It’s a clear injection molding material used to manufacture transparent parts like view screens, windows, and lighting components due to its remarkable optical properties. It has replaced glass because it provides strength and is resistant to harsh weather.

Nylon (PA)

Commonly used to produce automotive components like bearings, bushings, and gears because it’s lightweight, tough, and cheaper than metal. However, nylon can absorb water, so it may not be suitable for marine uses.

Polyoxymethylene (POM)

It’s an injection molding resin used to create mechanical components manufactured using metal. That includes parts like ball bearings, fasteners, knife handles, and gears.

Insert molding

A manufacturing process of molding thermoplastic materials around an insert to produce parts that incorporate multiple materials. The inserts are usually metal components intended to strengthen the mechanical properties of the plastic part.

Injection molding process

The cycle consists of the following four phases:

Clamping

A hydraulically powered clamping unit exerts enough force to keep the mold halves closed before the injection step.

Injection

The raw plastic pellets are delivered to the mold. In this stage, the material is melted through heating and high pressure.

Cooling

The coolant system cools the molten plastic in the mold, and it solidifies into the desired part.

Ejection

The cooled part is ejected from the mold cavities facilitated by the ejection system.

Advantages of injection molding

Here are some advantages of injection molded plastic parts:

Produced in large volumes

With injection molding, you can scale up production and manufacture large volumes. Fortunately, the overall cost of production reduces as the molding company makes more parts. Also, high volume production ensures consistency.

Low-cost production

High production output rate makes injection molding cost-effective.

Flexibility

You can choose the suitable material, design, and color to create your parts. And through custom plastic injection molding, we can craft excellent parts to suit your mold design.
