Quality Control

Our commitment to quality is paramount. As a result we've invested heavily in effective quality management and monotoring processes that can be relied upon for high quality products.

At the heart of our quality regime is our proprietary Statistical Process Control (SPC) system. Every part of our production process is recorded on SPC allowing complex computer models to monitor and maintain high production standards, which ensures a constant high quality across every finished product.

Samples are analyzed at all stages of production and the results are kept on computer record for a period of seven years. This ensures full traceability on every extruded, molded or skived product or machined component - from raw material to the finished article.

This quality system was first approved by the Aeronautical Inspectorate Directorate (AID) in 1956. Today, Dalau operates a 'TQM' Total Quality Management system that forms the basis of day-to-day production processes. We meet the exacting standards of:

  • AS 9100:2016 Rev D Aerospace and BS EN ISO 9001:2015 Approval (Certificate N°. Q05588)
  • UL (Underwriters Laboratories) certification. Dalcon 001 E135533
  • WRAS BS6920 Approval
  • Drug Master File: Listing N°. 20720

Control and support facilities

Specific facilities include ‘in-house’ blending technology and the introduction of a clean climate controlled production facility. A clean room system particularly for use in high specifications applications (aerospace and pharmaceutical etc) is available.

Precision product testing control

Precision product testing and control

As well as standard batch testing for quality, including tensile, stress and compression testing we also subject all semi-finished products to our unique Differential Scanning Calorimeter (DSC) testing. This ‘thermal fingerprinting’ provides important information about the material’s thermal behaviour and checks that the material has been fully sintered. Through its exact calibration DSC enables the recording of melting temperatures and molecular weight.

Complex temperature programs for all product samples provide effective data to quality control, minimizing operational inconsistencies. The result, higher integrity products for our customers.

Competition requires that products be of the highest quality. One's quality reputation depends on the quality of the measurements made. The video measurement technology of the OGP SmartScope CNC 250 can improve measurement throughput and accuracy.


Our CMM (Co-ordinate Measuring Machine) uses the latest technology to generate the highest measuring performance on complex, large components.

Hexagon Inspection Arm

Hexagon Inspection Arm

We have recently invested in this state-of-the-art, portable counter balanced CMM measuring arm.  It allows us to conduct our final inspection whilst the component is still in position on the machine.
