Injection Molding

Injection molding has been around since the mid-1960s and now dominates the rubber component marketplace. This process delivers inexpensive rubber components during mass production runs.

Injection molding is a process where a rubber compound is forced, or “injected” into a mold, where it cools down and hardens into the shape of the mold.

Injection molding is best when large quantities of the same part are needed. It is also useful if you require very low tolerances in the parts that are produced. The defect rate for injection molded products is extremely low.

The advantages of injection molding are compelling:

• The elimination of pre-forms (a labor intensive step that could negatively affect tolerances in the final product)
• The injection screw pre-heats material before forcing it into cavities, which leads to decreased cure times and more rapid filling to the form cavity).
• Reduced cycle time
• Flashless tooling
• Minimal material waste

The molds used for injection molding can also be quite intricate. This means we can produce pieces that are designed in very fine detail.

Injection molds are designed using 3D modeling software, ensuring that engineers have complete control over every dimension of the finished product.
