#component cleaning

[advancetechnology]

Shot blasting of components is a surface treatment in which abrasive materials called shots are blasted at great velocity onto the surface of a component. The process cleans, strengthens, and prepares such surfaces for further manufacturing processes such as welding, painting, or coating. It is a surface treatment that does away with rust, scale, and other unwanted materials, leaving a smooth, uniform surface finish on the component, while also increasing the durability and working life of the component.

Enhancing safety, cost-effectiveness in high precision component cleaning

Hymatic Engineering Coy Ltd, part of Honeywell Aerospace, based in Redditch in the UK, specialises in the design, development and manufacture of cryogenic and fluid control systems, sub-systems, and precision engineered products for aerospace and defence applications.

A key part of Hymatic’s production process is the cleaning of manufactured component parts using solvent-based vapour degreasing. Up until April 2016, the company had used trichloroethylene (TCE) as the solvent, but the EU now classifies TCE as potentially carcinogenic and has banned its use in degreasers. As a result, Hymatic contacted Honeywell to investigate alternative and safer solvent options capable of providing equivalent cleaning performance.

The Needs

Hymatic needed an alternative solvent to TCE to meet exacting cleaning standards required for small electronic components destined for aerospace and defence applications.

The solvent needed to be easy to handle with low levels of waste

Hymatic required a solvent with minimal impact on the environment both in usage and in disposal

The solvent needed to present a low risk to operative health
