Custom OEM Aluminum Die Cast End Cap – Precision CNC Machined for Industrial Applications

PRODUCT OVERVIEW

Our custom aluminum die-cast end caps are engineered for superior performance in demanding industrial environments. Manufactured using high-pressure die casting (HPDC) and finished with precision CNC machining, these components deliver exceptional dimensional accuracy, corrosion resistance, and lightweight durability for OEM applications.

KEY FEATURES & BENEFITS

✔ Premium Aluminum Alloys – A380, ADC12, or custom blends for optimal strength-to-weight ratio
✔ Precision Tolerances – CNC machined to ±0.05mm for leak-proof sealing surfaces
✔ Complex Geometries – Die casting enables intricate shapes with internal threads/knurls
✔ Surface Finishes – Anodized (Type II/III), powder-coated, or chromate conversion coated
✔ Rapid Prototyping – Supports low-volume batches to full production runs

FAQ:

1,What tolerances can you achieve with CNC machining?

Our CNC machining ensures tight tolerances of ±0.05mm (±0.002") for critical sealing surfaces. For ultra-precision applications, we can achieve ±0.02mm with post-machining processes.
