Aluminum extrusion profile
Aluminum Alloy Check
This verifies that the right type of aluminum billets are used for your extrusions. Some of the alloys specified by the International Alloy Designation System used for aluminum extrusions are 6063, 6463, 6005A, and 6061. Donrex covers all aluminum alloy standards recognized in various countries.
Visual Defects Check
Black specks, surface and internal cracking, surface lines, warps, uneven wall thickness, lumps, sharp edges, and uneven coatings are just some of the critical areas to be checked on this protocol. It is important that these are established by the buyer to serve as guide for both supplier and inspector. If you are not completely sure which defects to include, it may help if your supplier could provide samples as basis in establishing the pass and fail criteria for this process.
Color and Glossiness Check
There are various ways in order to verify color and glossiness of extruded profiles. The most common is by comparing finished products with approved samples or with agreed values on the Pantone color chart. If your requirement is more stringent, Donrex may use a spectrophotometer and a glossmeter. Checking of color and glossiness is done under simulated lighting conditions for accuracy.
The above-mentioned are just very few of the extrusions inspection processes that Donrex covers. If you are interested to know more of the inspection protocols applicable to your type of extrusion product, please do not hesitate to contact us for more information.
