Precision Manufacturing Solutions for Automotive Components
Blog Article
As a worker at Junying, I have the privilege of being part of a team that specializes in precision manufacturing for the automotive industry. Our recent project for a new energy vehicle (NEV) supplier was particularly challenging and rewarding. The client needed a highly precise and lightweight component for an integrated on-board charger connector housing. This project required not only high strength and conductivity but also precision interfaces for installation. Let me walk you through the entire process and how we managed to deliver a product that met the highest standards.
The Challenge of Precision Manufacturing
The automotive industry, especially the segment of new energy vehicles, demands components that are not only lightweight but also highly precise. Traditional manufacturing methods often fall short when it comes to complex geometries and tight tolerances. Our client's requirement for a ±0.01mm tolerance was a tall order, but our expertise in zinc die casting and CNC machining services made it possible.
The Zinc Die Casting Process
The first step in manufacturing the charger connector housing was to use zinc die casting. Zinc alloy is ideal for this application due to its low melting point and excellent mechanical properties. We used high-pressure die casting to form the complex cavity structure, including the heat dissipation fins and snap-fit structures. The surface roughness was controlled to within Ra1.6, ensuring a smooth finish right out of the mold.
Precision CNC Machining
After the initial die casting, the component required further precision machining. We utilized a five-axis CNC machining center to mill the installation holes and conductive contact surfaces. The use of an automatic tool setting system allowed us to achieve a precision of ±0.005mm, well within the client's specifications.
Quality Assurance and Testing
Ensuring the quality of our products is paramount. The final component underwent rigorous testing, including a 96-hour salt spray test to check for corrosion resistance. Additionally, we used a coordinate measuring machine (CMM) to verify that the dimensions met the IATF 16949 quality standards. The results were outstanding, and the client was extremely satisfied.
Project Timeline and Benefits
One of the most significant achievements of this project was the reduction in the development cycle. By integrating zinc die casting with precision CNC machining, we managed to cut the development time by 30%. This not only saved the client time but also reduced costs significantly.
