Strength-to-Weight Ratio That Robots Demand
Aluminum die castings offer 1/3 the weight of steel with comparable strength essential for robot agility, speed, and energy efficiency. Every gram saved in a robot arm directly improves cycle time and payload capacity.
Complex Geometries, Net-Shape Precision
Complex Geometries, Net-Shape Precision High-pressure die casting produces complex, near-net-shape robotic components in a single operation reducing secondary machining, cutting lead times, and improving consistency across production runs.
Thermal & EMI Management Built In
Aluminum's natural thermal conductivity and EMI shielding properties protect sensitive electronics in motor housings, encoder enclosures, and control system components from heat and interference.
Scale From Prototype to Mass Production
We support robot manufacturers at every stage from initial DFM analysis and rapid prototyping through full-rate high-volume production without requiring a supplier change
One-Stop Shop: Cast, Machine, Finish, Deliver
Casting, CNC machining, anodizing, powder coating, and assembly all under one roof. No multi-supplier coordination, no quality accountability gaps, no delays.
Alloys for Every Robotic Application
We cast aluminum and zinc alloys selected for their specific performance advantages in robotics
ADC12
Aluminum Alloy
Thin-Wall
ADC12 excels at thin-wall, lightweight casting critical for humanoid and collaborative robots where minimizing mass directly impacts agility, energy use, and battery life. Superior flowability enables intricate, detailed geometries.
- Outstanding thin-wall casting capability
- Excellent dimensional stability
- Low density maximum weight reduction
- High surface quality
- Humanoid frames, cobot links, wrist joints
A380
Aluminum Alloy
Most Used
The workhorse of robotic die casting. A380 delivers robust mechanical properties, excellent castability, and dimensional stability ideal for structural robot components and motor housings requiring reliable performance under cyclic load.
- High tensile strength and durability
- Excellent castability for complex shapes
- Good thermal conductivity
- Corrosion resistant
- Robot arms, motor housings, base frames
Zamak
Zinc Alloy (Z3/Z5)
High Precision
Zinc alloys offer tighter tolerances and finer detail than aluminum making Zamak the preferred choice for small, intricate robotic parts like gears, sensors, and encoder housings where dimensional accuracy is paramount.
- Tightest tolerances of any cast alloy
- Superior surface finish minimal post finishing
- Excellent for thin walls and fine detail
- Lower tooling costs, faster turnaround
- Encoder housings, gears, sensor mounts
Robotic Applications We Support
From industrial automation to humanoid robots, we produce the die cast components that keep robotic systems operating precisely, reliably, and efficiently.
Automotive, aerospace, and electronics manufacturers rely on six-axis industrial robots for welding, assembly, and material handling. We supply die cast aluminum arm housings, gearbox covers, base plates, and controller enclosures that are engineered for the duty cycles and payload ratings that industrial robot programs demand.
- Arm Housings
- Gearbox Covers
- Base Plates
- Controller Enclosures
- Wrist Joints
Cobots operate alongside human workers, making weight reduction and smooth exterior form critical. Our thin-wall aluminum die castings produce lightweight cobot link housings, shoulder and elbow joints, and integrated motor casings that improve agility without sacrificing strength.
- Link Housings
- Joint Covers
- Motor Casings
- End Effector Bodies
- Sensor Brackets
Humanoid robots are the fastest-growing segment of the robotics market. Every limb, joint, and structural element demands lightweight, strong, precisely cast aluminum components. We work with humanoid robot OEMs on torso frames, leg link housings, dexterous hand components, and foot structures using ADC12 and A380 for optimal strength-to-weight performance.
- Torso Frames
- Leg Housings
- Hand Components
- Foot Structures
- Actuator Mounts
Warehouse AMRs and logistics robots operate continuously in demanding environments. Our die cast aluminum chassis components, drive unit housings, sensor mounts, and electronics enclosures are engineered for the durability and dimensional stability that 24/7 autonomous operation demands.
