    3 Axis CNC Milling

    Injection molding stands as the predominant approach for mass-producing plastic goods. This method involves melting plastic, injecting it into molds, ejecting the finalized product, and then repeating the cycle.

    4 Axis CNC Milling

    Insert molding proves to be a highly practical injection molding technique that enhances the strength or other properties of the final part by integrating additional materials.

    5 Axis CNC Milling

    Overmolding is a process where various materials are layered to create a composite article. Typically, this method entails injecting a base material over one or more pre-existing parts to integrate them into a unified whole.
