What is
Precision CNC Machining

Precision CNC machining utilizes computer-numerical-control systems to manufacture components with micron-level accuracy for mission-critical applications in aerospace, medical instruments, and industrial automation. By executing digital designs with extreme consistency, it achieves dimensional tolerances as tight as ±0.005mm on complex geometries like hydraulic valve bodies, surgical tooling, and optical alignment fixtures – surpassing conventional machining capabilities.

With 5-axis simultaneous machining and real-time quality monitoring, this process ensures near-zero defect rates from prototype validation to mass production. Components such as precision gears, sensor housings, and fluidic connectors maintain strict compliance with functional specifications under ISO 9001:2015 certified quality systems.

CastMold specializes in automotive-grade precision machining with 10+ years of Tier-1 supplier experience, delivering components that withstand extreme temperature cycles and vibration loads in modern vehicle systems.

CNC Turning Services

CNC Turning is a computer-controlled machining process that rotates a workpiece while a stationary tool removes material to create cylindrical or conical parts. It delivers high precision (±0.01mm), repeatability, and complex geometries for components like shafts or bushings in industries such as automotive and aerospace. Compatible with metals, plastics, or composites, it supports rapid prototyping and mass production.

Gear Hobbing Services

Gear Hobbing is a machining method using a rotating hob to cut gears, splines, or sprockets. The hob and workpiece synchronize rotation, generating precise involute profiles. Efficient for high-volume production of spur, helical, or worm gears, it works with metals and plastics. Widely used in automotive and aerospace, CNC hobbing enables multi-axis automation for speed and accuracy.

Wire EDM Services

Wire EDM uses a charged wire (e.g., brass) to cut conductive materials via CNC-controlled spark discharge. Ideal for hard metals (titanium, tool steel), complex contours, and micro-features with no mechanical stress. Applied in tool/die, aerospace, and medical industries; supports multi-axis machining and automation.

Mirror EDM Services

Mirror EDM achieves extremely low surface roughness (Ra < 0.1μm) with near-mirror finish through ultra-fine discharge parameters and precision electrodes (e.g., graphite, copper). Ideal for high-gloss molds (plastic injection, die-casting), optical components, and applications requiring minimal post-processing polishing. It enables intricate curved surface machining but demands high-precision CNC control and multiple discharge finishing passes to refine details.
