An experienced master craftsman
Advanced CNC machining center
We have targeted and solved the four major assembly problems: deviation of aluminum bracket holes, thin-walled deformation, and size compensation during anodization. We can provide customized machining solutions for robot joint components, liquid cooling cavities, and structural components of automated equipment.
Specialized in solving four major assembly problems: the accuracy of aluminum bracket hole positions, thin-wall deformation, anodization, and size compensation. Suitable for custom processing of robot joint parts, liquid cooling cavities, and automated structural components.
Through digital programming, automated high-precision processing is achieved, ensuring that the size accuracy and surface finish of batch products are stable and uniform. The product tolerance can be strictly controlled within an extremely narrow range of ±0.02mm.

Comparing the advantages of traditional powder metallurgy
An integrated and formed complex structure reduces the assembly gaps of multiple parts, enhances the strength and durability of the components, and offers a more favorable cost advantage for mass production.
The value-added services provided by this factory
After forming, it can undergo a complete set of post-processing such as CNC secondary fine processing, deburring, anodizing, passivation, and electroplating. The fastest time for drawing review and quotation is 5 hours. It also supports sample production and batch customization.
MIM core equipment
Injection Molding Machine
Specialized MIM feeding injection molding equipment, which mixes metal powder with binder as raw materials and injects them under high pressure into the mold to form near-net-shape complex part blanks. It can match customer's customized special structure drawings.
Debinding Furnace
The environmentally friendly degreasing process removes the binder from the interior of the blank before sintering, preventing the product from cracking or deforming, and serving as a pre-treatment step for the sintering process.
Vacuum Sintering Furnace
Sintering the degreased preforms in a high-temperature vacuum environment makes the parts denser. The finished product's density can reach over 97% of the theoretical density of the material, and the mechanical strength and dimensional accuracy are significantly improved.






Overcoming four assembly bottlenecks
Regarding the dimensional stability of the aluminum brackets in the automated equipment, we focus on the processing details that directly affect the performance of the product.
Bore position accuracy control
Anodic oxidation size compensation
Control of thin-walled deformation
Through precise CNC processing and three-coordinate measuring instrument inspection, the tolerance of the control hole position is controlled within ±0.02mm, eliminating the deviation in automated assembly.
Pre-calculate a 0.02mm surface treatment increase in thickness, and apply the machining allowance during the cutting process to ensure a perfect fit between the thread and the shaft hole when the product is manufactured.
Optimize the tool path and the support of the dedicated fixture to eliminate the residual stress from cutting, ensuring that the thin-walled bracket maintains a high degree of flatness in a vibrating environment.
Bore position accuracy control
By optimizing the fixtures and managing the sequential assembly process, the deformation caused by clamping during the processing stage can be reduced, thereby enhancing the stability of mass production.
Assembly stress control

Strict pre-production engineering review
Before the tools and materials came into contact, we had already conducted digital simulations and process reviews to avoid all potential assembly and tolerance risks.

design.Analyze the STEP drawings, estimate the dimensional changes caused by the process, and output feedback on manufacturability design.
Special tooling fixtures were designed for the thin-walled structure, and customized anti-deformation cutting paths were created. Then, precise CNC processing was carried out.
