Injection Moulding Services

Injection moulding is the most cost-effective way to make a plastic part at scale and offers consistent quality for low-to-high-volume manufacturing. Xometry UK offers a vast number of rigid plastics and resins that meet the required structural and cosmetic characteristics. Beyond materials, injection moulded parts can have custom finishing, polishes, or surface textures. Xometry UK offers both high-precision tool manufacturing and injection moulding services.

Xometry Injection Moulding Capabilities


Injection Moulding, Insert Moulding, Overmoulding

Lead Time

Starts at 10 business days


Rapid Tooling: recommended for 100-10,000 parts / Production Tooling: recommended for over 10,000 parts


Plastics and resins

Machines Available

Single, multi-cavity, and family moulds; 50 to 1,100+ press tonnage; side actions including hand-loaded cores

Mould Cavity Tolerances

± 0.1 mm when machining the mold and an additional ± 0.05 mm when calculating for shrink rate

Part to Part Repeatability

±0.1 mm or less

Critical Feature Tolerances

Tighter tolerances can be requested and may increase the cost of tooling because of additional sampling and grooming. Xometry will mill to a steel-safe condition on critical features.

Available Mould Types

Steel (tool steel, carbon steel) and aluminum; Production grades range from Class 105, a prototype mold, to Class 101, an extremely high production mould.
