Frequently Asked Questions
What are the primary advantages of the aluminum cover?
The cover offers exceptional durability, superior strength, and high corrosion resistance due to its high-quality aluminum construction. Its strong thermal conductivity also provides excellent heat control to prevent base station overheating.
What materials and machinery are used in the die casting stage?
We utilize an 800T aluminum die casting machine and ADC12 material. The furnace temperature is controlled at 670°±20° with a material handle of 20±2 mm. Secondary materials are strictly not utilized.
What measures are taken during CNC processing to ensure surface quality?
During CNC processing, we verify that the machined surface finish meets Ra0.8. We perform deburring, chamfering of sharp corners, and polishing of non-machined ejector pins. Go and stop gauges are used to check limits, and product flatness is strictly verified.
How is the quality of the powder spraying process tested?
The regional and organizational powder spraying is tested using specialized equipment including a colorimeter, film thickness meter, salt spray tester, hundred grid tester, alcohol resistance test, and pencil test to ensure color consistency and no surface defects.
What precautions are implemented during packaging and shipping?
We inspect the goods against samples for dents or scratches. The tooth profile must pass inspection. Products are packed with dividers, bubble wrap, and desiccant, then wrapped in flat cardboard. Before shipping, quantities are matched, outer boxes are labeled/stamped, and measuring instruments are verified to be within calibration.
