High-Precision LED Structural Components: Integrated Die Casting + CNC Solution
Customer Requirements:
A large listed LED display manufacturer in China requires high product precision, especially flatness and verticality within 0.1 mm. Stringent surface salt spray resistance requirements must also be satisfied.
Solution:
The components are integrally formed by aluminum alloy die-casting, combined with one-time 4-axis CNC machining to ensure stable product precision fully meeting drawing specifications. Black electrophoretic coating is adopted for surface treatment in accordance with the customer’s application requirements.
Results & Feedback:
Delivery: Custom aluminum alloy die-cast LED display structural parts, CNC precision machined components, as well as complete salt spray test reports and dimensional inspection reports were delivered on schedule, with 100% compliance with acceptance standards.
Customer Evaluation: "The process of integrated aluminum alloy die-casting plus 4-axis CNC machining perfectly achieves flatness and verticality at the 0.1 mm level. The black electrophoretic finish has also passed our salt spray tests, providing reliable assurance for the outdoor stability of the product."
Follow-up Cooperation: After six months of online operation, the products exhibited no structural deformation or surface corrosion. We have designated this supplier as a core strategic partner and placed additional long-term orders for a full range of display structural parts.
