Send us your CAD and get a manufacturable part. We review the design, machine the prototype, and hold the same tolerance when the order reaches 10,000 units.
Most of these show up after tooling is cut or after the first production run ships.
A wall thickness or draft angle that looked fine in CAD becomes a weld line or a short shot in the mold. Rework means new inserts, new lead time, and a schedule that slips by weeks. DFM feedback before cutting metal is cheaper than DFM feedback after.
A one-off part can be hand-fitted until it works. If the drawing does not carry real datums and tolerance, the production lot will not assemble the same way. The gap usually surfaces at the pilot build, not at the prototype.
Prototype shop, die caster, and finisher each read the drawing differently. Thread callouts, surface finish, and heat-treat condition get reinterpreted. You end up inspecting parts against a spec nobody agreed on.
Switching from 6061 to 7075 after first articles changes machinability, anodize color, and sometimes the process itself. The cost is not the material. It is re-quoting, re-cutting, and re-validating the parts already made.
Design review, machining, finishing, and inspection under one roof in Dongguan.
Upload a STEP file and we return a quotation plus a free DFM analysis within 12 hours. The review covers wall thickness, corner radii, thread depth, datum strategy, and which features need a 5-axis setup versus a 3-axis one. If a feature is cheaper to redesign, we say so before quoting.
The point is to catch manufacturing limits while the design is still soft. Moving a hole 3 mm, opening a pocket corner to match a standard cutter, or changing a tolerance that no process can hold are all cheap changes at this stage.
A prototype run of one part and a production run of 10,000 use the same machines, the same inspection routine, and the same material certificates. There is no minimum order quantity. We machine one piece to prove the geometry, then use the proven program for the larger batch.
For parts that will eventually be die cast or injection molded, we machine the bridge quantity first so the assembly can be tested. The machined parts give you functional test data months before tooling is ready.
Pick by geometry and quantity, not by habit.
| Stage | Process | Why |
|---|---|---|
| Concept, 1–20 parts | 3-axis or 5-axis CNC | No tooling cost, design can still change |
| Pilot, 20–500 parts | CNC or vacuum casting | Functional testing before hard tooling |
| Bridge to volume | CNC or die casting | Keeps assembly builds running during tooling |
| Volume, 10,000+ | Die casting, then CNC finishing | Lower piece cost on complex housings |
| Thin sheet parts | Sheet metal fabrication | Brackets, panels, and enclosures |
| Complex internal channels | Custom 3D printing | Geometry a cutter cannot reach |
Six services that cover most hardware programs.
16 simultaneous 5-axis centers for contoured surfaces, angled holes, and parts that need one setup. Good for aerospace brackets, impellers, and robot joints.
27 three-axis machines, 12 four-axis mills, and 16 mill-turn centers. Shafts, housings, and turned parts with cross features in a single cycle.
Machined prototypes from a STEP file. Fits and function tested before tooling. Ships in 3–5 days with no minimum order quantity.
Aluminum and zinc die casting for housings and frames at volume, with CNC finishing on critical faces after casting.
Silicone tooling for 20–500 urethane parts. Useful for pilot builds when the final material is not yet locked.
Anodizing, plating, powder coating, bead blasting, and laser marking. Laser marked characters hold a minimum height of 1.5 mm.
Travel figures are the actual working envelope, not the machine footprint.
| Machine type | Travel or size | Typical parts |
|---|---|---|
| Large 5-axis | 4,000 × 400 × 150 mm | Long structural rails and beams |
| Medium 5-axis | 750 × 1,150 × 550 mm | Housings and mid-size frames |
| Compact 5-axis | 500 × 500 × 450 mm | Brackets, plates, small joints |
| 4-axis mill with rotary | Ø400 mm rotary table | Cylindrical parts with cross holes |
| Mill-turn | Ø400 mm and up | Shafts with milled flats and slots |
| Maximum part size | 4,000 mm | Anything longer needs a split design |
These are the figures we hold ourselves to.
15 years of metal cutting across 3 wholly-owned plants covering 7,600 m². The process knowledge comes from parts that failed, not from a brochure.
That is ±0.0002 in on critical dimensions. We tell you when a dimension does not need to be that tight, because tight tolerance costs cycle time.
Quotation plus free DFM analysis inside 12 hours. Production can start within 24 hours of a released order and confirmed material.
Raw material check, in-process monitoring, and final inspection on every lot. Inspection reports issued on request.
ISO 9001:2015, IATF 16949:2016, ISO 13485:2016, and ISO 27001:2022. Medical and automotive programs are covered by the same system.
One prototype or 10,000 production parts. No setup fee to reach a minimum batch size, and no penalty for ordering one piece.
Joint housings and actuator brackets need stiffness without mass, held across a production run.
Battery enclosures, busbars, and drivetrain brackets must meet IATF 16949 documentation.
Instrument housings and fixtures need a clean finish and traceable material lots.
Structural brackets and fittings need contoured surfaces machined in one setup for alignment.
A STEP or IGES file plus a 2D drawing for tolerances and finish. If the drawing is not ready, send the 3D model and tell us which dimensions are critical. We quote from the model and flag dimensions that need a tolerance call.
PDF drawings are fine. We do not require a specific CAD package.
±0.005 mm on critical dimensions, which is ±0.0002 in. That figure applies to features we can reach in a stable setup, usually on a 5-axis or mill-turn machine.
Long thin parts, deep pockets, and unsupported walls move under cutting force. Those features get a realistic tolerance call in the DFM review rather than a number on a drawing that cannot be met.
Use 5-axis when a part has angled faces, contoured surfaces, or features on several sides that would otherwise need multiple setups. Fewer setups means fewer datum shifts and better alignment between features.
Stay with 3-axis for flat plates, simple pockets, and prismatic parts. It is faster and cheaper, and there is no accuracy benefit to 5-axis on a part that only has one working face.
Yes, and it is a common path. We machine the bridge parts so the assembly can be tested while the die is being cut. The machined geometry and the cast geometry are not identical, so we review draft angles and wall thickness before the die design is frozen.
Plan the gate and ejector locations early. Moving them after the die exists means welding and re-cutting the tool.
As-machined is Ra 1.6–3.2 μm. Bead blasting and tumbling bring it to Ra 0.8–1.6 μm. Fine finishing reaches Ra 0.2–0.8 μm on sealing faces and sliding surfaces.
Specify the finish only where it does something: a seal face, a sliding bore, a visible cosmetic surface. Applying a fine finish to the whole part adds cost with no functional gain.
Uploads are secure and confidential. We sign an NDA on request before files are shared, and access to customer data is limited to the people quoting and machining the part.
Our information security management system is certified to ISO 27001:2022.
There is no minimum. One prototype and a 10,000-part run go through the same shop. The reason is simple: most programs need one part to prove the design, then a larger batch once it is validated.
Shipping is typically 3–5 days after production starts, with production able to begin within 24 hours of a released order.
Every lot is inspected 100% before shipment, with raw material check, in-process monitoring, and final inspection. Dimensional reports are available on request.
For high-volume runs we agree on a control plan up front so the inspection method matches the feature being checked.
