Testing Facilities
Our partners provide a fully manual quality testing procedure as this is more reliable than machine-based testing. This has been designed to complement the powder coating process by testing the thickness and adhesion of the powder to the finished product. This is to ensure that the powder coating process has been completed successfully in accordance with our strict quality procedure. The powder coating plant accepts items up to 4000 mm long by 12000mm heights by 700mm deep, however, bigger sizes could be accommodated. This plant has a seven stage pre-treatment system. The main powder coating plant accepts items up to 7000mm long x 3000 height x 1000mm deep. Additionally, in exceptional cases, it will accommodate items up to 12000mm long where the track can be converted into a box oven. This plant has an online pre-treatment system. The six stage pre-treatment process consists of the following:
- Combined degreasing for all materials It is very important to prepare the metal object for further procedures by removing any dirt, oil, welding scales and more. Decreasing is the first part of pre-treatment system before powder coating application
