Tooling & Injection Molding

Tooling & Molding

Using injection molding technology we are able to create pre-production, short-run and mass-production parts in a wide range of plastic and elastomeric materials.

Our capabilities include CAD design, CAM, CNC machining, single & multi-cavity tools, Moldflow®, insert & over-molding and finishing.

Our experienced Melbourne-based team will walk you through the entire process from:

  • Picking the right type of injection tooling for your project
  • Select the right plastics
  • Design validation
  • Final product quality assessment

Working closely with you we’re able to provide a service that is cost-effective, timely and reliable.

From Conception to Completion

At GoProto, we’re able to work with you from prototype to production, reducing lag time in communication between multiple suppliers, and eliminating the “Blame Game” often played when working with multiple companies.

Injection Molding

Injection molding is the process of injecting molten plastic into a steel tool to form your parts. We have access to a wide range of plastic and elastomeric (rubber) materials and can use filled materials. We also manufacture two-shot and insert-moulded parts.

Injection Tooling

Plastic injection moulding tools are integral to modern manufacturing. We specialise in both low volume and high-volume quantities.  Our team will assist you throughout the tooling design process, including:

  • Parting lines, gate locations, ejector pins
  • Drafting
  • Moldflow analysis

With a huge range of production plastic and elastomeric materials, we utilise traditional technologies such as machining and EDM directly from your CAD files to quickly create tool inserts.  These parts can have complex geometry, undercuts, threads, etc.
