The robotics industry requires components that balance low weight with structural strength, dimensional accuracy, and long service life. We provide integrated custom die casting and precision CNC machining services for robotic parts, serving industrial clients across manufacturing, healthcare, and logistics sectors. Our capabilities cover the entire production cycle from mold design to finished component delivery, supporting both prototype development and high-volume manufacturing.
We use high-pressure die casting to produce near-net-shape robotic components. Molten metal alloys are injected into precision steel molds at pressures ranging from 100 to 1000 bar. This process creates complex geometries with consistent wall thicknesses and minimal material waste. Standard die casting tolerances are ±0.05mm for most dimensions.
All die cast blanks undergo secondary CNC machining to meet strict application requirements. We offer 5-axis CNC machining, wire EDM machining, drilling, tapping, and deburring services. CNC finishing achieves tolerances as tight as ±0.02mm for critical features such as gear meshing surfaces and bearing bores.
Aluminum Alloys (A380, A356, ADC12): Density of 2.7 g/cm³, tensile strength of 260 MPa for A380. Used for robotic arm links, motor housings, and structural frames.
Magnesium Alloys (AZ91D, AM60B): 35% lighter than aluminum, with vibration damping capacity of 20% higher than A380. Suitable for cobot joints and wearable exoskeleton components.
Zinc Alloys (Zamak 3, Zamak 5, ZA-8): Dimensional stability of ±0.03mm per 100mm, with inherent EMI shielding properties. Used for gearbox housings and sensor mounts.
Weight-Strength Balance: Magnesium die castings reduce component weight by up to 50% compared to steel while maintaining equivalent structural integrity.
Dimensional Consistency: Die casting produces parts with repeatable dimensions across production runs of 100 to 100,000+ pieces.
Integrated Design Capability: Multiple components can be combined into a single casting, reducing assembly time and part count.
Thermal Management: Aluminum castings provide thermal conductivity of 96 W/(m·K), supporting integrated cooling channels for motor and drive systems.
Production Efficiency: The combined die casting and CNC process reduces total manufacturing time by 30-50% compared to fully machined parts.
