BJS operates and maintains precision machining in parallel with accurate measuring equipment to ensure all parts are made repeatedly to within tolerance.

Physical checks are made to all industrial components to ensure consistency and that they meet the customers’ requirement.

BJS operates a Mitutoyo Coordinate Measuring Machine (CMM) in its Quality Assurance Department. 

Electroplating and electroforming solutions are maintained using both wet analysis and AAS analysis of the metallic content.

BJS also operates an X-ray Fluorescence (XRF) Analyser which can accurately measure the thickness of a plated metal layer by exposing a sample to be measured to a beam of X-rays.  The atoms of the sample absorb energy from the X-rays, become temporarily excited and then emit secondary X-rays.  Each chemical element emits x-rays at a unique energy and by measuring the intensity and characteristic energy of the emitted X-rays, the XRF analyser can provide qualitative and quantitative analysis regarding the composition and thickness of the plated material being tested. 

It can also analyse the amount of metal contained within electroplating and electroforming solutions and therefore acts as a backup and comparison to our AAS.

Class 7 Cleanroom

BJS Operates a Class 7 Cleanroom which is annually audited independently and certificated to ensure strict compliance to BS EN ISO 14644 Part 1 (Cleanrooms and associated controlled environments – Classification of Air Cleanliness) and BS EN ISO 14644 Part 2 (Cleanrooms and associated controlled environments – Specification for testing and monitoring to prove continued compliance with ISO14644 Part 1).

We offer therefore the cleaning and packaging of electroplated parts to ensure they are suitable for aerospace, space and scientific applications where absolute cleanliness is essential.
