Surface Engineering

Sandwell UK Ltd is a highly professional company focused on specialist surface engineering solutions for top level clients. Specialist skills with excellent product knowledge in Shot Peening technologies and Surface Engineering are key to the company’s success. We are always pushing surface finishing boundaries with new innovative techniques, whilst always meeting our customers needs and expectations.

Bead Blasting

Bead blasting is the surface engineering process of either glass bead blasting or ceramic bead blasting at a surface to improve its general surface finish or to remove surface contaminates.

Benefits and Features
  • Improves surface finish post manufacture
  • Can be used to decontaminate surfaces
  • Option of glass or ceramic bead
  • Refines surface post Shot Peening

Satinising

Our satinising surface engineering process employs a range of in-house media processes to produce the surface finish you require. Typically the process of gently blasting the surface with a glass bead media will enhance the finish of machined parts and produce a bright, non-glare and finely textured subtle surface finish.

Benefits and Features
  • A non glare surface finish
  • Consistent decorative finish for industrial and domestic products
  • Used on range of electrical and digital equipment
  • Aluminium parts can be anodized to enhance finish

Chemi Blacking

The Chemi Blacking surface engineering process is most effective on most low and high alloy steels with the exception of high chrome austenitic and martensitic stainless steels. It produces a lustre finish dependent on base material condition that doesn’t significantly affect frictional properties.

Benefits and Features
  • Cosmetic cold blacking process
  • Can be used on most steels
  • Used on fasteners & small fabrications
  • Minimal surface build up

Superfinishing

Our superfinishing surface engineering process is designed to refine and polish surfaces to enhance component performance. This is an engineered finish with the benefit of producing a low friction surface that reduces rolling resistance.

Benefits and Features
  • Produces fine low friction surface
  • Increases power efficiency
  • Reduces contact stress
  • Reduced operating temperatures

Advanced Superfinishing

Our superfinishing surface engineering process is designed to refine and polish surfaces to enhance component performance. This is an engineered finish with the benefit of producing a low friction surface that reduces rolling resistance.

Benefits and Features
  • Used to reduce stress concentration
  • Able to achieve high quality surfaces finish on internal profiles
  • Used to locally finish radii-undercuts-splines-holes
  • Improves local finish on all metals
