Dust-free injection moulding refers to the injection moulding process that takes place in a clean environment. Dust-free moulding is carried out in a clean room, which is an environment with strict air purity controls, usually through air filtration systems to minimise particles and contaminants. Cleanrooms are classified according to different levels of cleanliness, such as ISO 5, ISO 6, ISO 7, etc. Dust-free injection moulding is usually carried out in an ISO 7 or higher class environment to ensure that the product is not contaminated during the production process.

Established in 2014,Kaierwo dust-free injection moulding workshop has a class 10K dust-free injection moulding workshop and assembly workshop, with the waste, loading and mixing workshops completely separated to prevent mutual influences between different production processes. The raw materials used are also stored and handled in a clean environment to prevent contamination during the injection moulding process.

The equipment used in Kaierwo dust-free injection moulding service, including injection moulding machines, moulds, and peripheral equipment, meets the standards for use in clean rooms to reduce static electricity and particles generated by friction. Operators are required to wear dust-free garments for strict cleanliness control to prevent contaminants such as dust and dander generated by the human body from entering the production environment.

Throughout the production process, a variety of online and offline testing methods are typically used to monitor product quality and ensure that the finished product meets cleanliness and functionality requirements. These include optical testing, air tightness testing, surface quality testing, etc.

The Class 100,000 cleanroom provides a controlled environment suitable for industries that require a certain level of cleanliness but do not need to meet extreme cleanliness requirements. Examples include electronics manufacturing, semiconductor packaging, printed circuit board assembly (PCBA), optical equipment, optical fibre manufacturing, pharmaceutical manufacturing, medical equipment, spacecraft components, biotechnology equipment, etc.
