Injection Molding Applications

Rapid Prototyping

Although injection molding is best suited for medium to high volumes, the use of low cost tooling allows injected molded parts to be produced very rapidly and cost effectively. In almost every case, an injection 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.

End-Use Production

Injection 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 with injection molded parts to save weight and fight corrosion.

Injection Molding Advantages

Rapid Turnaround

Using our vetted Partner Network, Xometry is able to produce top quality Injection Molded parts in as little as 10 business days.


Injection Molding can be the ideal process for production runs of 250-25,000+ parts.


Injection Molded parts will generally perform better than the same part CNC Machined from the same material. Careful selection of the resins allow for a wide range of corrosion resistance and chemical and solvent compatibility.


Injection molds are CNC machined to high precision, high tolerances and are able to produce thousands of identical parts with very small and intricate details.


In higher volumes, injection molding produces significantly less waste than other manufacturing processes.

Part Production

Piece price is significantly lower with Injection Molding vs other processes, particularly as production quantities increase into the thousands.

Injection Molding Processes

Thermoplastic Injection Molding

We are able to deliver top quality plastic injection molded parts in as little as 10 business days. Xometry's 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 for applications in automotive, aerospace, consumer products, industrial / energy, and medical / pharmaceutical industries.

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. And with Xometry, you own your own tools, so our partner network also offers mold maintenance services.
