Clean Room Moulding

Clean room moulding is used in situations where contamination of parts during the production process could be hazardous - for example, the production of certain medical devices or aerospace components. The moulding process must therefore take place in a clean room - a sterile room which is especially designed to reduce the possibility of contamination by dust or other pollutants.

In the interest of reducing the introduction of contaminants, operators entering a clean room environment are generally covered with gowns, shoe covers and masks. The equipment used is also electronic rather than hydraulic, which results in less contaminants in the air.

Clean room moulding generally uses injection moulding, although other moulding methods can be utilised. Due to the care and attention taken to avoid contamination, clean room moulding is usually more expensive than conventional moulding, although depending on the end application, it is sometimes essential.

Used to produce

Moulded parts that are free from contaminants.


The material will depend on the moulding method used. However, as clean room moulding generally uses injection moulding methods, common materials are acrylic, polycarbonate, ABS, PEEK, and polypropylene.


Parts produced via clean room moulding will have much lower levels of contamination than parts produced via conventional moulding methods.


Due to the extra care and attention taken to avoid contamination, clean room moulding is usually more expensive than conventional moulding.

What is the best method for suppliers to contact you?

We will be putting suppliers in contact with you directly so they can quote your project. Some suppliers may have questions so they can quote you correctly. Additionally, most suppliers usually like to follow up to see how they got on and all we ask is that you provide them with feedback, whether they have won the project or not. With this in mind what is the best method to reach you on (you can choose both)?
