Custom Plastic Injection Moulding Services
Find custom plastic injection moulding services on Towobo — PP, HDPE, ABS, PC, and engineering resin injection moulding for consumer goods, industrial components, packaging, household products, and OEM parts manufacturing. Injection moulding is the dominant process for high-volume plastic part production globally, serving buyers from household goods importers to automotive tier suppliers and medical device manufacturers.
Injection moulding process capabilities — what to specify
Injection moulding uses a heated barrel to melt plastic resin, which is injected under pressure into a precision steel or aluminium mould. When specifying injection moulding services, buyers should clarify: Part dimensions and weight: larger, heavier parts require larger machines (higher clamping force, typically measured in tonnes). Shot weight in grams determines the machine size needed. Material capability: most custom moulders process standard thermoplastics (PP, HDPE, LDPE, ABS, PS, PC). Engineering resins (nylon PA6/PA66, POM, PBT, PPS, PEEK) require machines with higher barrel temperatures and specialised tooling. Confirm the manufacturer processes your required material before requesting a quote. Tolerance requirements: standard injection moulding tolerances are ±0.1–0.2mm for consumer goods; precision parts require tighter tolerances down to ±0.02–0.05mm, which requires higher-precision tooling and slower cycle times. Surface finish: texture (SPI or VDI finish standards), gloss, or specific appearance requirements must be specified in the mould design. Secondary operations: painting, pad printing, assembly, ultrasonic welding, insert moulding, and packaging can be offered by full-service moulders.
