Precision CNC Machined PU Part Per Drawing from China

CNC Machined Polyurethane Components

Our CNC machining centers produce machined PU components with tight tolerances and smooth surface finishes. We work with solid PU billets, sheets, and custom-cast blanks to manufacture complex geometries, including grooves, undercuts, threaded holes, and precision bore features.

Custom PU Parts Per Drawing

Every machined PU part in China is produced strictly according to your 2D drawings, 3D CAD files, or physical samples. We accept DXF, STEP, IGES, and PDF formats, and our engineering team reviews every design for manufacturability before production begins.

Prototype to Mass Production

From one-off machined PU part development to full-scale serial production, we support every order volume. Single-piece prototypes, small-batch runs, and large-scale manufacturing are all handled with the same level of precision and quality control.

Material & Hardness Flexibility

We machine PU parts across a full shore hardness range, from soft 30A elastomers to rigid 95A polyurethane and TPU materials. Custom formulations are available for oil resistance, hydrolysis resistance, high-temperature performance, and food-contact compatibility.

Our CNC Machining Process for Polyurethane

Every machined PU component in China follows a controlled production workflow designed to ensure dimensional accuracy and consistent material properties. The process begins with a thorough review of your drawing and material requirements.

We select appropriate PU or TPU stock material based on hardness, chemical resistance, and operating temperature. Raw material is then fixtured on our CNC machines, and programmed toolpaths are executed to mill, turn, drill, and finish the part to exact drawing specifications.

Secondary operations such as deburring, polishing, surface grinding, and assembly are performed as required. Each part undergoes dimensional inspection before shipment, with full inspection reports available upon request.

We produce custom PU parts per drawing for both standard and highly specialized applications, with lead times optimized for both prototype and production quantities.

Why Choose Our CNC Machined Polyurethane Components

CNC machining offers superior dimensional accuracy compared to molded PU parts, making it ideal for tight-tolerance sealing components, precision rollers, custom gaskets, and mechanical wear parts. Machining also eliminates tooling costs for low-volume orders.

Our machined PU parts exhibit excellent abrasion resistance, high tear strength, and reliable performance across a wide temperature range. Polyurethane outperforms rubber in many industrial applications, offering longer service life and better load-bearing capacity.

As a China-based manufacturer specializing in machined PU part production, we offer competitive pricing, flexible production scheduling, and direct engineering support. We work directly with OEMs, distributors, and engineering companies worldwide.

Whether you need a single machined PU component for testing or thousands of parts for assembly, we deliver consistent quality and on-time production.

Available PU & TPU Materials

We machine polyurethane components from a wide range of thermoset PU and thermoplastic TPU materials, each formulated for specific performance requirements.

Shore hardness options range from 30A to 95A for elastomeric grades, and up to 75D for rigid polyurethane materials. We also offer specialty grades including oil-resistant PU, hydrolysis-resistant PU, flame-retardant PU, and FDA-compliant polyurethane.

Our machined PU parts are available in standard colors including black, natural amber, blue, red, and green. Custom color matching is available for larger production orders.

All materials are selected based on your application requirements, operating environment, and performance specifications outlined in your drawing.

Industries & Applications

CNC machined polyurethane components are used across a broad range of industries where wear resistance, sealing performance, and mechanical durability are critical.

Common applications include hydraulic and pneumatic seals, piston rings, rod wipers, custom gaskets, wear pads, rollers, bumpers, vibration dampeners, conveyor components, and custom mechanical parts for automation equipment.

We supply machined PU parts to the hydraulic industry, automotive sector, packaging machinery, material handling systems, medical equipment, marine applications, and general industrial manufacturing.

Every custom PU part per drawing is engineered to meet the specific functional requirements of its intended application, with material selection and machining processes optimized accordingly.

Order Volume

From single prototype pieces and small batch runs to high-volume mass production. We support quantities from 1 piece to 100,000+ pieces per order.

Dimensional Tolerance

Standard machining tolerance of ±0.05mm, with tighter tolerances down to ±0.01mm available for precision applications. All tolerances verified by inspection.

Part Size Range

We machine PU parts from miniature components under 10mm to large-format parts up to 500mm in diameter, with custom sizes available upon request.

Machining Processes

CNC milling, CNC turning, drilling, tapping, boring, surface grinding, contour cutting, and custom secondary finishing operations.

Quality Assurance Process

Every machined PU component in China passes through multiple inspection stages throughout production. In-process checks verify critical dimensions, and final inspection confirms all drawing specifications are met.

Our inspection equipment includes coordinate measuring machines (CMM), 2D optical projectors, digital calipers, micrometers, hardness testers, and surface roughness gauges. We maintain detailed inspection records for every production batch.

Material traceability is maintained from raw material receipt through final shipment. We verify material hardness, dimensional accuracy, surface finish, and visual quality for every order.

First Article Inspection (FAI) reports are available for new part introductions, and full dimensional inspection reports can be provided upon request for production orders.

How to Submit Your Drawing

To produce custom PU parts per drawing, we require complete technical specifications including all dimensions, tolerances, material requirements, hardness, surface finish, and any special notes.

Accepted file formats include STEP, IGES, DXF, DWG, and PDF drawings. 3D CAD files are preferred for complex geometries. If you only have a physical sample, we can reverse-engineer the part and create a production drawing.

Our engineering team will review your drawing and provide feedback on manufacturability, material recommendations, and any design considerations that may affect cost or lead time.

We work with customers worldwide to produce precision CNC machined PU parts from China, with clear communication throughout the quoting and production process.
