Injection molding is a manufacturing process that consists of filling a metal mold cavity with liquid plastic resin, which then cools and forms a plastic part.

It’s most often used for the manufacturing plastic parts at scale due to its low material waste and low cost per part. It’s an ideal manufacturing process for industries like medical devices, consumer products, and automotive.

Plastic Molding Capabilities

Our basic guidelines for plastic injection molding include important design considerations to help improve part moldability, enhance cosmetic appearance, and reduce overall production time. 

	US	Metric
Size	18.9 in. x 29.6 in. x 8 in.	480mm x 751mm x 203mm

Tolerances: Typically, Protolabs can maintain a machining tolerance of +/- 0.003 in. (0.08mm) with an included resin tolerance that can be greater than but no less than +/- 0.002 in./in. (0.002mm/mm).

Plastic injection moulding and mould production

General information

We are specialists in the injection moulding of small series.

We use moulding materials such as epoxy and polyester, which are filled with metal, quartz sand and other fillers. We also use low/medium melting point alloys to produce simple structural moulds. This type of mould has a simple manufacturing process, a short cycle and a low price. This is ideal for small and medium batches. Quantities from 500 to 5,000 parts can be produced with single or multiple cavities. We also offer polishing and texturing for the surface of the moulds.

For large batches, we use the standard mould process.

Materials for injection moulding

Here you will find a list of our standard materials for injection moulding. If you require customised information, please contact us.

POM, PC-ABS, ABS, PET, PA66, PMMA, PA-GF, PPS, HDPE, PP, LDPE, PS, PBT, PS-PPE, PC, TPE, PC-GF, TPV

Component finishing

• Polishing
  Polishing is used to reduce the surface roughness and to obtain a smooth, mirror-like surface.
• Laser engraving
  A surface treatment process based on optical principles.
• Texturing
  Is a surface treatment of moulds which improves the beauty and strength of the surface.
• Pad printing
  A printing process in which text, graphics and images are applied to irregularly shaped surfaces.
• Individual colour coating
  The use of an air pressure gun enables the colourant to be applied evenly and efficiently to the surface to be treated.
• Screen printing
  The screen printing process is the method of choice in advertising technology and labelling, in textile and ceramic printing, for high-quality effect finishes and in industrial printing.
• Heat treatment
  Heat treatment results in a change in the chemical composition and structure in the solid state.
