Dawang Precision
Our custom aluminum structural frame is designed to maximize rigidity while minimizing weight. Using advanced finite element analysis, we optimize the internal rib structure to reduce material usage without compromising structural integrity. This results in components that are up to 35% lighter than traditional cast aluminum parts, enabling faster operating speeds, improved energy efficiency, and easier handling during assembly and maintenance.
Every 5-axis CNC structural housing is manufactured in a single piece using 5-axis CNC milling technology, eliminating the deformation and fatigue issues associated with welded structures. Critical positioning holes are controlled within ±0.01mm tolerance, ensuring perfect coaxial alignment between motors, reducers, and sensors. This precision translates to improved positioning accuracy, reduced vibration, and longer equipment lifespan.
We understand the importance of fast product development cycles for industrial equipment manufacturers. Our streamlined production process delivers high-quality samples in just 7-10 days from CAD drawings, allowing you to quickly test and validate your designs. We support production volumes from 100 to 10,000 units, with consistent quality across every batch.
Whether you are a robot integrator, laser equipment manufacturer, or automation equipment OEM, we offer one-stop custom aluminum structural frame solutions:
7–10 days from CAD drawings to samples
Mass production support for 100–10,000 units
Surface treatments (anodizing, hard anodizing, sandblasting) available
Complete quality documentation (CMM reports, material certificates) provided with every shipment
We help customers overcome the challenges of “heavy weight, poor precision, and long lead times,” making your equipment lighter, faster, and more reliable.

With 26 years of experience and ISO 9001, ISO 14001, IATF 16949, and ISO 13485 certifications, you can trust Dawang Precision to deliver high-quality, reliable components that meet your exact specifications. Our customized packaging and logistics solutions ensure timely delivery to your facility, anywhere in the world.
A renowned European manufacturer of industrial collaborative robots and intelligent automation equipment faced significant technical challenges during the development of their next-generation 6-axis robotic arm. They required a lightweight, high-rigidity housing to mount core motors, reducers, and sensor systems. Traditional cast aluminum parts were too heavy and lacked the required precision, while welded structures suffered from deformation and fatigue issues, resulting in limited operating speed and unstable positioning accuracy.
Dawang Precision developed a custom high rigidity aluminum structural part using 7075-T6 aluminum alloy. Our 5-axis CNC machining technology allowed us to integrate complex 3D surfaces, large-diameter precision bores, and optimized internal ribs into a single, seamless component. We also applied hard anodizing surface treatment to enhance wear resistance and corrosion protection.
The implementation delivered exceptional performance improvements:
Single part weight reduced by approximately 1.8kg (35% lighter than the previous solution)
Robot end-effector repeatability improved from ±0.025mm to ±0.008mm
Vibration reduced by 28% during high-speed operation
Maximum operating speed increased by 18%
Successfully passed 72-hour continuous high-load fatigue test with zero deformation
The client has now adopted our lightweight aluminum robot frame as the standard configuration for their entire next-generation collaborative robot line, significantly reducing their development time and improving product performance.
Our precision CNC machined aluminum structural housing is ideal for applications where weight reduction and high precision are essential:
Robotics and automation: Robotic arm bases, housing frames, and end-effector mounts
Optical and laser equipment: Precision instrument mounts and lens mounting frames
Industrial machinery: Equipment structural components and motor mounting housings
Medical and diagnostic equipment: Frames for high-end imaging and diagnostic systems
New energy equipment: Lightweight structural support components for solar and wind systems
Aerospace and defense: Precision components for unmanned aerial vehicles and ground systems
