Established guidelines on quality control inspection of extruded aluminium profiles and flat stock, pre-worked panels and sheet materials.
EXTRUDED ALUMINIUM PROFILES: (Goods / Materials Received):
QC Inspection procedures are applied to all extruded aluminium profiles, upon notice from Planning Department of the receipt of unloaded profiles.
Q. C. PROCEDURES:
Ensures all delivered materials are as per purchased orders (furnished to QC by Sales upon ordering of materials), an actual physical count is conducted. Profile configurations are also checked against approved die drawings. General material descriptions are noted in this stage. Suppliers are advised of any shortfalls.
Visual Check (Quality):
This ensures acceptable limits of good surface finish. The following are checked in each and every profile bar:
1. Scratches: scratches are not acceptable on all visible surfaces and are subject to rejection if noted.
2. Marks & Die Lines: permanent marks caused by ropes, tapes, water stains are not acceptable. Jigs marks are acceptable only when confined within the 50 mm waste cut at each end of the profile; bar.
3. Mechanical Damage: dents and other deformities caused during handling, transport, etc. are not acceptable and are subject to rejection.
Any defects noted by Quality Inspectors are clearly marked on subject profiles. Instrument Check: Precision instruments are used to measure and / or check quality and specifications such as anodic coating thickness and colour range limits.
