quality assurance

We are aware that quality is one of the top priorities of our customers.

Here at Difa, we are committed to consistently achieve the highest standards of quality throughout the business operations of the entire company, with the purpose of manufacturing defect-free products, respecting and achieving prearranged tolerances, and becoming the first and best supplier in the industry while consistently respecting the principle of information security and minimising our impact on the environment.

We strive to continuously improve all our processes which are strictly controlled at all levels, in order to allow us to meet the applicable standards.

We guarantee quality assurance through:

  • Q DAS
  • APIS


Some of the methods that we use:

  • FMEA
  • SPC
  • MSA
  • Statistical methods


Our cutting-edge laboratory is one of the cornerstones for providing the highest level of quality.

We develop products and services which are completely adapted to the wishes and needs of our customers. Guaranteeing the quality of these products according to required standards requires precise measurements, analyses and various tests in the process development phase, as well as in the process manufacturing phase. Using various measurement devices and processes in our laboratory, our highly skilled experts monitor product quality and tolerance.

Based on in-depth analyses and testing, we transfer our solutions from the laboratory to the manufacturing department where we adjust our processes according to plans.
