Control and flow of C-type iron core process
Some high-end products come from strict process control. Our company is very strict with every process link, in order to make all technical indicators higher than international indicators and other companies. Next, I will introduce to you the control and flow of the C-type iron core process.
First of all, in the selection of materials, we are very targeted. For the order requirements of different customers, we will personally select the corresponding materials, and each material will have a certificate of conformity and a test report provided by the merchant, as well as IQC review test data. . The second step is slitting. We use selected slitting equipment and hard and straight alloy knives. The production capacity of each machine is very strong, which can reach 2T/day. The third step is winding, using high-precision dual-axis driven automatic iron core winding equipment. Its production capacity reaches 11 tons per day. Although our coefficients vary for different materials, the control force is very good. Generally, for new materials with a thickness of 0.23--0.25mm, the lamination coefficient is 0.97 or 0.98; for new materials with a thickness of 0.1--0.2mm, the value of the lamination coefficient for new materials; for new materials with a thickness of 0.05--0.08 The value is 0.90 or 0.91. Next is shaping. The company strictly requires that the end face must be flat. In addition, 4 steel belts are used to fix the shaping in order to increase the accuracy of size and shape control. The fourth step is annealing. In this step, 12 nitrogen-filled mesh belts and a high-vacuum annealing furnace are used. The nitrogen generator can provide 250m3/hour of high-purity nitrogen with high quality. Then vacuum pressure impregnation paint is automatically dried after demoulding. Imported ring resin paint is used. After grinding and polishing. Ultrasonic cleaning is used to clean, and a special water-based anti-rust liquid is added to wash the rust. Finally, the finished product is packed in anti-shock packaging, which is vacuumed and anti-rust with vapor phase anti-rust paper.
