Reduce unit costs and scale production with reliable high-volume CNC machining. TENGHUI operates 50+ CNC machines to support repeat production of custom metal and plastic parts, with consistent quality, scheduled deliveries, and monthly volumes exceeding 5,000 pieces for suitable projects.
Optimized machine toolpaths, dedicated multi-part fixturing, and bar-fed continuous operations configured for repeatable quality and minimum unit cost.
Supports repeat production of brackets, housings, enclosures, frames, plates, heat sinks, fixtures, and other prismatic components.
Suitable for custom shafts, pins, bushings, spacers, fluid fittings, sleeves, threaded connectors, and other rotational parts.
Actual capacity and tolerance capability depend on the part size, material, geometry, machining time, surface finish, and inspection requirements.
A systematic 6-stage engineering workflow designed for maximum repeatability, strict quality control, and on-time batch delivery.
We review your 3D CAD models, 2D drawings, materials, tolerances, quantities, and inspection requirements. Our engineers identify potential manufacturing risks and optimize toolpaths to reduce machining time and part cost.
We select suitable machines, cutting tools, workholding methods, and machining sequences. Custom multi-part fixtures and dedicated setups are engineered to ensure high production efficiency and setup repeatability.
Initial sample parts are manufactured and fully inspected before releasing full batch production. Critical dimensions, materials, surface finishes, and appearance are verified strictly against agreed specifications.
Following first-article sign-off, production proceeds using documented setups, automated bar feeding, and controlled cutting parameters. Tool condition and critical tolerances are monitored at scheduled intervals.
Components undergo deburring, ultrasonic cleaning, secondary surface treatments (anodizing, plating, heat treatment), and final metrology. Full CMM inspection reports and certificates are provided upon request.
Parts are securely packaged with protective separation tailored to finish requirements. Single consolidated shipments or scheduled recurring batch deliveries can be scheduled according to project timelines.
Our standard CNC machining tolerance is typically ±0.05 mm. Precision tolerances down to ±0.01 mm can be achieved for selected critical features after detailed engineering review.
Avoid specifying extremely tight tolerances on non-critical dimensions. Unnecessary tight limits significantly increase machining cycles, inspection overhead, scrap risk, and overall production unit costs.
Practical engineering recommendations to shorten machining cycles, minimize tooling wear, and achieve the lowest unit cost for batch orders.
Standard material grades, plate thicknesses, and bar diameters are easier to source, reduce procurement lead times, and lower raw stock unit costs for repeat production.
Designing components so critical features can be accessed in fewer part orientations reduces handling, fixture changes, setup time, and accumulated positional errors.
Deep pockets require long-reach tools and slower feed rates. Limiting cavity depth or increasing internal corner radii extends tool life, prevents tool chatter, and shortens cycle times.
Specify tight tolerances only where critical for function, fit, or mating interfaces. Applying standard commercial tolerances to non-critical dimensions drastically lowers cycle times and QA inspection costs.
Using standard drill sizes and common metric or imperial thread pitches eliminates custom tool grinding, speeds up machine setups, and streamlines threaded gauge inspection.
Provide fully dimensioned 2D PDF drawings showing datums, critical tolerances, specific thread classes, cosmetic surface finishes, and CMM inspection requirements prior to quoting.
Scalable manufacturing capacity, rigorous metrology controls, and end-to-end production support from pilot runs to multi-thousand monthly deliveries.
Successful high-volume CNC machining requires more than machine capacity. It depends on stable workholding, repeatable programs, controlled tooling life, and dedicated quality metrology.
CAM programming, machine setup, custom fixtures, and first-article inspections represent fixed upfront manufacturing investments. As production volume increases, these costs are distributed across larger lot sizes, substantially reducing the final cost per unit.
For suitable parts, we engineer multi-part workholding fixtures, standard tooling libraries, optimized high-efficiency toolpaths, and nested stock layouts to shorten cycles and eliminate raw material waste.
High-Volume Impeller Production & Scale Economics
Continuous Lathe Operations & Automated Feeders
Our fleet of 50+ CNC machines allows flexible equipment allocation tailored strictly to part geometry and scheduled volume demand. Automatic bar feeders, pneumatic chucks, and standardized multi-part setups maximize continuous production speed.
Monthly production capacity and machine hours are confirmed upon detailed review of your part drawing, material grade, cycle time, tolerance bands, and finishing requirements.
Validated CNC programs, rigid workholding, active tool-wear monitoring, and routine in-process dimensional measurements ensure identical geometrical and cosmetic consistency from the first component to the ten-thousandth.
First-Article Inspection (FAI), calibrated Coordinate Measuring Machine (CMM) reports, raw material mill certificates, and surface-treatment certifications are systematically verified and provided upon delivery.
Batch Array Alignment & Strict Repeatability
There is no single quantity that applies to every component. Several hundred pieces may be considered high volume for a large or complex part, while smaller components may be produced in batches of several thousand.
The appropriate production method depends on part geometry, material, machining time, tolerance, finishing, and delivery requirements.
Yes. Monthly volumes exceeding 5,000 parts are achievable for suitable projects. Actual capacity depends on the component size, complexity, cycle time, material, surface finish, and inspection requirements.
Send us your drawings and expected monthly demand so that we can evaluate production capacity accurately.
We use approved machining programs, stable fixtures, controlled machining parameters, tool-life monitoring, in-process inspection, and final batch inspection.
Critical dimensions can also be verified using go/no-go gauges, optical measuring equipment, or CMM inspection according to project requirements.
Yes. Initial parts can be manufactured and inspected before full-scale production. Batch production begins strictly after the required dimensions, materials, surface finishes, and appearance standards have been approved.
Yes. We can arrange partial shipments or scheduled batch deliveries based on the confirmed purchase order, production forecast, material availability, and agreed delivery schedule.
Our general machining tolerance is typically ±0.05 mm. Tolerances down to ±0.01 mm may be available for selected critical features after engineering review.
Achievable tolerances depend on material, part geometry, feature size, surface finish, and inspection requirements.
Use standard materials and stock sizes, reduce the number of machining setups, avoid unnecessarily deep pockets, increase internal corner radii, and apply tight tolerances only to critical features.
