The cooperation with aluminum die-casting housing customers began with preliminary demand research. We communicated with customers many times to understand their technical requirements and expectations in detail, including material composition, dimensional tolerances, surface treatment and functional requirements. Based on this information, we developed a preliminary production plan.
After confirming the project requirements, we started the proofing phase. Our engineers made samples based on the customer's design drawings and conducted preliminary functional tests. After completion, the samples were sent to the customer for confirmation. After receiving the samples, the customer made a preliminary evaluation of their appearance and size and provided feedback on areas that needed improvement. In response to the customer's feedback, we immediately arranged a meeting for in-depth communication with the customer. We discussed the problems in the samples, including technical details such as the passivation time not meeting the standard, the surface treatment sequence and the tightness of the screw threads. The customer made specific requirements for certain details, and we responded quickly and developed a corresponding mold modification plan.
Through a series of adjustments and optimizations, we solved the problems in the original sample. Adjust the passivation solution concentration and extend the immersion time to improve corrosion resistance. The optimization order is sandblasting first and then anodizing to ensure surface finish. Set standard torque values and implement strict torque tests. Confirm the seal position during the mold design stage to ensure accuracy.
After confirming the improvement plan for the sample, the customer decided to come to China for an on-site inspection in person. They were very interested in the changes and mold modification process we made. On site, the customer conducted a comprehensive evaluation of the sample, focusing on the size, appearance and overall quality. Our team showed the customer the improved sample and explained in detail the reasons and expected effects of each change. After the customer's on-site confirmation, the two parties reached an agreement and the sample was finally approved. We then entered the mass production stage. During the production process, we strictly followed the optimized process to ensure that every link can meet the customer's standards. By using high-precision equipment and strict quality control, we ensured the stability and consistency of the product.
The mass production was completed smoothly, and the customer was very satisfied with the quality and delivery time of the final product. The customer reported that the appearance and functionality of the product met their expectations and expressed the hope to establish a long-term cooperative relationship with us. This not only strengthens the trust between us and our customers, but also lays the foundation for more cooperation in the future.
