What is Plastic Injection Molding?

Plastic injection molding refers to the process where molten material is injected within a pre-designed mold. Using thermoplastic and thermosetting plastic materials, this process melts the materials until they are soft enough to be injected into the mold which allows us to create the custom parts you need on a large-scale in a timely manner. No matter what your needs may be, the dedicated team at Wilbert Plastic Services will work hard to produce products that will fit your goals.

Advantages of Using Plastic Injection Molding


Once the mold has been created to the customer’s specifications, the plastic injection molding process itself is very quick.

Detailed and Complex Part Designs

Since injection molds can withstand high amounts of pressure, the plastic within this mold is pressed harder and more accurately into intricate designs than with other molding processes. Once the design is created, the molding process will go by just as quickly as with a basic design.

Enhanced Strength

Depending on the type of product being produced, the customer will need to inform the manufacturer of how flexible or rigid they’d like the outcome to be. Plastic injection molding allows for variations in durability and can be adjusted to fit your product needs.

Flexibility with Materials and Colors

Plastic injection molding allows for the use of many different types of plastic simultaneously. You also can choose between colors depending on what the desired outcome is. To determine which resin is best for your project, you must keep in mind elasticity, impact & tensile strength, heat deflection, and water absorption.


In the injection molding process, excess plastic is produced. We can melt this excess back down to reuse in another project to cut back on waste.

Decreased Labor Costs

The ability to produce parts at a high level and high output rate requires less labor. A majority of the process is computerized and manufactured in an assembly-like system. This can help reduce labor costs associated with plastic injection molding.
