Production Process
1. After the order is confirmed, we will purchase bars, wires, plates, raw materials from professional raw material manufacturers. After the incoming inspection is qualified, arrange for warehousing.
2.Our senior engineer will debug the machine according to the drawings, write the program, and then start the machine to make several samples to check whether the size is in compliance.
3.Different products will have different process steps. All departments of the factory will cooperate in processing. There will be quality inspection between each step to check the size.
4. After the product is finished, we will deliver it to a professional surface treatment factory for surface processing, and then return to the factory to check the tolerance.
5.Our packing department will carry out the final packing according to the requirements of customers and do a drop test.
Quality Control
-We will use plug gauge, pass gauge and caliper to test parts for general tolerance.
--For products with high customer requirements and strict tolerances, we will use Vision measurements to ensure that the tolerances are within the allowable range.
--If the customer has requirements for hardness and corrosion resistance, we will also issue a corresponding report to the customer for inspection.
