The current high-gloss black grid manufacturing process is achieved by spraying high-gloss black lacquer. The parts obtained by painting are good in appearance and stable in performance, but the process requirements are high, the painting technology is limited to paint dead angles, and orange peel is easy to appear. The defects in the appearance of paints such as pockmarks are reduced, the defective rate of parts is 20%-30%, and it can not be recycled and reused. For these shortcomings of high gloss black paint, it is cost-effective, easy to operate and energy-saving. Under the demand, in the past two years, the products and processes of the spray-free high-gloss grid appeared, which changed the process of painting before the injection molding, and directly molded the bright black grid.
1) Raw material inspection;
2) Part visual inspection & dimension inspection;
3) Mold inspection before T1 trial;
4) Mold CMM inspection;
5) Mold disassembly to inspect cooling system, injection system, ejection system before shipment, etc.
The mould stared to pack with wooden case after the final sample confirmed,then the mould will be sent to port and waiting for shipping.
