Injection Molding Service

  • Custom molded prototypes and production parts with fast lead times

About Injection Molding

  • We deliver high-quality, on-demand injection molded parts. Injection molding is the most cost-effective way to make a plastic part at scale and offers consistent quality for low-to-high volume manufacturing.
  • Molding also has the highest variety of materials, colors, and configurations when compared to CNC machining or even 3D printing. Beyond materials, injection molded parts can have custom cosmetics, polishes, or surface textures.

The Advantages of Injection Molding
Fast production
  • Injection molding can produce a huge amount of parts per hour, depending on how many impressions are in tool, but you’re looking at something between 15-30 seconds for each cycle time.
Material and Color Flexibility
  • When you have, your tool made, you can change the material and color of the part that you’re producing.
Labor Costs Low
  • A self-grating, automatic tool runs on an injection molding machine without very much difficulty at all. Your parts can be readied with little or no labor on top of the production.
Design Flexibility
  • Injection molded parts have an almost limitless amount of flexibility, you just need to be able to design around certain restrictions outlines below.
Low Waste
  • The majority of plastics recycle – the plastic waste is usually grinded up and reused.
Injection Molding Processes
Thermoplastic Injection Molding
  • We deliver top quality plastic injection molded parts in as little as 10 business days. Our Manufacturing Partner Network can help you design and manufacture tools, dies, and molds for rapid tooling for prototyping to advanced mold making for production runs. Full injection molding capabilities including insert molding, overmolding, unlimited undercuts, and internal/external threads are available.
Mold Making
  • Our vetted network of partners allow us to quickly convert your 3D part data into a high-quality injection mold at top speed. We offer services from design and manufacturing for tools, dies, and molds for prototyping and production runs. Plastic blow molds, aluminum and steel tooling, 2-shot and 3-shot molding are also available.  you own your own tools, so our partner network also offers mold maintenance services.
  • Our network is skilled at overmolding. With overmolding, one material, usually a thermoplastic elastomer (TPE/TPV), is molded onto a second material, which is often a rigid plastic. Think about your toothbrush handle where the single piece has both rigid and rubbery components. It’s a great way to make plastic parts perform and look better.
Insert Molding
  • We now also offers insert molding as part of its injection molding capabilities. We can even use our CNC machining services to produce custom metal and plastic inserts to integrate into the part. For a free insert molding design review and quote, upload your CAD files. Our expert team of injection molders will get back to you within 24 hours.

Applications for Injection Molding
Rapid Prototyping
End-Use Production
ough molding is best suited for medium to high volumes, the use of low cost tooling allows molded parts to be produced very rapidly and cost effectively. In almost every case, a molded part will outperform the same 3D printed or machined part from the same material. And depending on the part geometries and the material selected, low cost tooling can last for many tens of thousands of parts. Molding is best known for producing production parts in the many thousands or even millions. With the advent of newer higher strength materials and fillers such as glass and carbon fiber, parts previously made out of metal are being replaced wit molded parts to save weight and fight corrosion.
