JMA aluminum Company has a complete set of production processes and mechanical equipment from
aluminum profile research and development, casting, extrusion, mold design and manufacturing, surface treatment (oxidation, electrophoresis, powder spraying, fluorocarbon spray painting), thermal insulation profile processing, door and window curtain wall deep processing, etc.
High-quality products rely on strict quality control, and strict quality control can create high-quality aluminum profiles. Quality control must be carried out throughout the pre-production preparation stage and all aspects of production and processing, including individual self-inspection to random inspection of each product, and even full inspection for complex products.
Before production, the drawing requirements must be fully and carefully checked, and the parts that are prone to errors must be marked and kept in mind. During the processing and production process, you must concentrate on the product, handle it with care, and accurately measure each dimension to ensure precision processing. After each profile is processed, it must be checked again to see if it is correct.
The responsibility of the industrial aluminum profile assembly department is to carry out self-inspection and inspection based on the drawings, comprehensively control every detail and processing requirement in the assembly process, and assemble strictly in accordance with the requirements of the drawings without any slackness. A comprehensive self-inspection should be carried out on the well-organized industrial aluminum profile products to check whether there are omissions or negligence. The quality control department conducts comprehensive random inspections and careful inspections on products with special requirements.
When all inspections are normal, qualified industrial aluminum products will be sent to the packaging department, where surface cleaning, finishing and packaging are carried out to prepare for shipment.
JMA Aluminum implements 100% online quality inspection and conducts final inspection before shipment. Before shipment, customers can either send a dedicated person to our company for quality inspection or entrust a third party to perform the inspection. We solemnly promise that the product will have no scratches, deformation, or bruises within one meter, and the color uniformity of the surface treatment is based on the sample. 100% quality inspection before shipment is only to give customers peace of mind.
