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.
