Xometry can assemble and label injection molded parts. Discuss your needs with your Xometry representative.

Injection molding is used across a wide range of industries including aerospace, medical devices, consumer goods, energy, electronics, automotive, robotics, toys, and more.

With the molding process, plastic or metal parts are created inside a mold. They are then removed from the mold as fully-formed parts. 3D printing, on the other hand, is an additive manufacturing process, meaning that the part is built layer-by-layer using processes like deposition or sintering.

After receiving the order, the statement of work is reviewed by one of our manufacturing engineers. A case manager is assigned, and an appropriate manufacturing supplier is identified. A comprehensive DFM/PEG report is created and provided for approval. Upon approval, tooling and mold production is commenced. T1 samples are produced and shipped for approval. Upon approval, the remaining parts are made.

At Xometry, our customers own their injection mold tools! After a run is complete, the tool will remain at our facilities. Tools can be shipped to you upon request; however, you will be responsible for any associated shipping and packaging costs. Our engineers will work with you regarding tool compatibility with your equipment if you're unsure.

Yes, multiple colors can be run even on the same order! When running multiple colors on the same order, a purge charge will be added.
