We manufacture rotational components, structural parts, complex multi-axis parts, thin-wall precision components, and fully custom parts based on CAD drawings.
Description
Machining Capabilities
Rotational Precision Components
· Sleeves & bushings (precision-fit rotational interfaces)
· Threaded mechanical parts (internal/external threads with controlled pitch accuracy)
· Rotary connectors & cylindrical components (used in motion systems and assemblies)
Structural & Load-Bearing Components
· Brackets & mounting plates (structural support in assemblies)
· Frames & mechanical housings (machine structural systems)
· Enclosures & protective casings (equipment protection and integration)
· Gearbox housings & support bases (power transmission structures)
Complex Geometry Components
· Multi-axis components (3/4/5-axis machining for complex geometry)
· Irregular structural parts (non-standard engineering shapes)
· Aerospace-grade brackets & connectors (high-precision structural interfaces)
·Integrated functional assemblies (multi-feature single-component design)
Thin-Wall & High-Precision Components
· Thin-wall housings & shells (structural stability under low thickness)
· Instrument & sensor mounting parts (precision alignment structures)
· Optical components (high-accuracy positioning surfaces)
· Lightweight precision structures (weight-optimized engineering parts)
OEM & Custom Drawing-Based Parts
· OEM replacement parts (reverse engineering or direct replacement)
· Prototype validation components (design verification before mass production)
· Small batch production parts (low-volume engineering supply)
· Fully customized engineering components (non-standard industrial parts)
