Hansheng Automation (Dongguan) Co., Ltd. is one of the most experienced manufacturers and suppliers of cnc milled prototypes and production parts in China. If you're going to wholesale bulk cost-effective cnc milled prototypes and production parts made in China, welcome to get pricelist and quotation from our factory. Also, customized service and OEM&ODM service are available.
In the world of product development, the gap between a CAD model and a physical part is defined by precision. We bridge that gap. We offer premier CNC Milled Prototypes and Production Parts services, catering to industries where "good enough" is never an option-such as robotics, aerospace, tobacco machinery , medical devices, and high-end automation.
Unlike standard machine shops, our facility is built upon a foundation of manufacturing ultra-precision harmonic drives and planetary gearboxes. Whether you need a single complex aluminum prototype for a fit-check or 5,000 stainless steel structural parts for mass production, we apply the same rigorous quality control and high-speed machining strategies to ensure your parts meet the strictest geometric tolerances.
Core Milling Capabilities
We specialize in subtractive manufacturing. By combining advanced 3-axis and 4-axis milling with specialized post-processing, we deliver parts that match your exact specifications.
High-Precision CNC Milling
Standard Milling Accuracy: We routinely hold ±0.01mm on complex geometric features.
Complex Geometries: utilizing advanced CAM software, we can machine intricate manifolds, housings with deep pockets, and non-prismatic shapes.
Ultra-Precision & Mirror Finishing
For parts requiring optical-grade flatness or air-tight sealing surfaces, standard milling isn't enough. We integrate Precision Grinding and Super-Finishing processes into our workflow.
Achievable Tolerance: Down to ±0.002mm.
Surface Finish: Capable of achieving Mirror Finishes (Ra < 0.1µm), ideal for semiconductor equipment and medical optics.
Large Format Machining
Size is often a limitation for precision shops-but not for us. Our facility is equipped with heavy-duty Horizontal Machining Centers.
Maximum Capacity: We can machine large plates, frames, and machine bases up to 2100mm x 1060mm.
Benefit: This allows us to produce monolithic parts for automotive chassis prototypes or large industrial equipment without the need for welding or assembly.
Equipment Highlights
Our shop floor is a blend of high-speed efficiency and heavy-duty stability. We utilize top-tier machinery to ensure consistency from the first cut to the final pass.
Taesin CNC Milling Machines
Known for their rigidity, these machines allow us to mill hard metals (like Tool Steel and Titanium) with minimal vibration, ensuring superior surface finishes.
Large Horizontal Machining Centers (HMC)
With a work envelope of 2100mm x 1060mm, these machines are the workhorses for your largest projects, offering faster chip evacuation and higher stability than vertical mills.
Seibu Wire Electric Discharge Machine (WEDM) M50B
Milling cutters cannot create perfectly square internal corners or cut through hardened steel with zero stress. Our Seibu WEDM complements our milling capabilities, allowing for the creation of intricate internal profiles and tight-radius features that traditional milling cannot reach.
Kashifuji Gear Skiving Machine (KPS30)
If your milled part requires integrated splines or gear teeth, we can machine them in-house to ISO Grade 5 standards, eliminating the need for you to send parts to a secondary gear supplier.
Our Advantages
Why should you trust us with your CNC projects? Because we treat every milled part with the same care as a high-precision robot joint.
Strict quality control: We utilize inspection equipment designed for measuring backlash in arc-seconds. Such as gear measuring centers, level gauges, etc.This means measuring linear dimensions on a milled block is well within our comfort zone.
One-Stop Fabrication: From Casting (Sand, Gravity, Lost Foam) to CNC Milling and final Surface Treatment, we manage the entire lifecycle. You get a finished product, not just a raw machined part.
Material Versatility: We are experts in machining a wide range of materials.
Metals: Aluminum (6061, 7075), Stainless Steel (303, 304, 316L), Carbon Steel, Brass, Copper, and Titanium.
Plastics: POM (Delrin), PEEK, Nylon, ABS, and Polycarbonate.
Scalability: We are agile enough to deliver CNC prototypes in 3-7 days, yet robust enough to ramp up to thousands of units using our automated machining setups.
Quality Management
Quality is not an inspection step; it is a manufacturing parameter. Our QA department is equipped with state-of-the-art metrology tools to verify every dimension, position, and surface requirement.
Verification
CMM (Coordinate Measuring Machine) verification for 3D geometries.
Documentation
We provide First Article Inspection (FAI) reports, Material Certifications, and Heat Treatment reports upon request.
Standards
Our process adheres to ISO standards, ensuring that the part you receive matches your CAD file exactly.
Don't let manufacturing limitations hold back your design. whether you need a single "Golden Sample" or a batch of 500 precision housings, we are ready to execute.
Upload your CAD files (STEP/IGES/XT) and PDF drawings today. Let our engineers review your design for manufacturability (DFM) and provide you with a competitive proposal.
FAQ
Q: What is the tightest tolerance you can achieve for milled parts?
A: For standard CNC milling, we hold ±0.01mm. However, for critical features, we can utilize our precision grinding and honing capabilities to achieve tolerances as tight as ±0.002mm and ultra-flat mirror finishes.
Q: Can you handle large CNC machined parts?
A: Yes. With a maximum processing size of 2100mm x 1060mm on our Horizontal Machining Centers.
Q: Do you offer surface finishes for milled parts?
A: Absolutely. We offer standard "as-milled" finishes, as well as bead blasting, anodizing (Type II and Type III), powder coating, nickel plating, and electropolishing.
Q: Can you machine parts from castings?
A: Yes, this is one of our core strengths. We can provide the casting service (Sand, Gravity, or Lost Foam) and then perform the precision CNC milling on the cast parts to ensure critical dimensions are met.
Q: My part has an integrated gear tooth. Can you make it?
A: Yes. Unlike most job shops, we have in-house Gear Skiving and Hobbing capabilities. We can machine parts with integrated gear features to ISO/DIN Level 5 accuracy without outsourcing.
