What we do
Our Manufacturing Capabilities
Integrated processes built to support aluminum parts from tooling and manufacturing through finishing, inspection and delivery.
DIE CASTING
High-pressure die casting (HPDC) with 200T–2000T machines for complex, high-precision components with smooth surface finishes.
ANODIC OXIDATION
Aluminum anodizing creates a hard protective oxide layer with corrosion resistance and a choice of attractive colors.
