Bollhoff quality

We don't leave good quality to chance - at Bollhoff Armstrong it is systematically planned.
Interdisciplinary teams working in close collaboration with our customers pre-plan quality into all new processes and products.


Outstanding quality management system

AS9100 REV C

Bollhoff Armstrong is a quality-oriented service provider and partner to innovative industries. We serve the aerospace industries, automotive, engineering, power and electrical engineering companies. Customers define their own technical specifications. Where requested, our application experts will provide assistance with defining specifications and their feasibility in production. Our customers benefit from Bollhoff Armstrong quality by avoiding unnecessary costs and through maximum process reliability. Once a quality specification has been decided we make sure it is implemented to the letter. It comes as no surprise that we are A-class suppliers to many companies and have been awarded Gold Star Supplier to a major UK aero distribution group.

Qualified suppliers

Qualified suppliers and controls on incoming materials

Incoming inspection

incoming inspection

The first important step for ensuring the highest quality specifications is selecting suitable suppliers for raw materials, semi-finished products and fasteners. Long-term partnerships with suppliers is our guarantee of safety and reliability. In clearly defined audits, we regularly check that all processes are being adhered to on site at our suppliers.
Our suppliers must undergo a multi-stage qualification procedure before they are authorised to supply. Site visits to supplier facilities play an important part in this process. We like to inspect manufacturing processes, quality management, process reliability and test equipment in person, on site.
If first impressions are positive we then perform tests and controls on various trial deliveries. Only when all trial deliveries have passed our technical incoming goods inspection without any deviations, will the supplier be approved and incorporated into our QEM rating system.
Not only does this reduce quality control costs for our customers, it also accelerates the internal flow of goods.

Reliable production

Reliable production thanks to preventive quality management planning of processes and products

CASQ-it 9000 – The modular approach

CASQ-it 9000
The modular approach

Before the start of production an inter-departmental team plans and specifies all the production, assembly and test processes which could have an effect on the quality of manufactured components or environmental factors.
We implement the following processes here:

  • Failure mode and effect analysis (FMEA)
  • Initial environmental assessment
  • Preparation of detailed production and work plans
  • Preparation of quality management and test plans
  • Machine capability studies
  • Process capability studies
  • Preventative maintenance

Specially trained employees check day-to-day production at SPC measuring stations using detailed inspection and test specifications. At the customer's request we then perform 100% checks using state-of-the-art digital technology.
