ENGINEERING & TECHNICAL SUPPORT
Free DFM Review Before Steel Is Cut
We are a machine shop first — our engineers review your part for machining, EDM, grinding and inspection feasibility before any steel is cut. Free DFM feedback within 24 hours, with a process plan matched to our own equipment.
What Our DFM Review Covers
Machining Feasibility & Tool Reach
Deep cavities, thin walls and 5-axis collision avoidance verified against our CNC, wire EDM and jig grinding capabilities before programming starts.
Tolerance & Datum Strategy
Critical dimensions flagged, the datum scheme confirmed and CMM inspection points planned so ±0.005 mm features stay measurable and repeatable through the run.
Steel Selection & Heat Treatment
Cavity steel, hardness and coating matched to wear, corrosion and mirror-finish needs — NAK80, S136, SKD61, H13 and more, with in-house vacuum heat treatment up to HRC 62.
EDM & Grinding Process Plan
Wire EDM at ±0.002 mm, mirror sinker EDM at Ra 0.02 µm and Waida jig grinding at 0.0005 mm applied where each process earns its cost.
Seamless 6-Step Project Execution

FREQUENTLY ASKED QUESTIONS
How to Order from Our Capability Floor & Frequently Asked Questions
Common questions about machining tolerances, lead times, steel selection, trials and documentation.
No MOQ for prototyping — we support 1-piece samples and scale to full production runs of 10,000+ pieces. Whether you need a single replacement component or bulk batch production, all order volumes are accommodated.
Standard machining at ±0.005 mm and critical features at ±0.002 mm. Waida jig grinding holds 0.0005 mm roundness, wire EDM cuts to ±0.002 mm, mirror EDM reaches Ra 0.02 µm, and Toshiba SPDT diamond turning resolves to 0.0001 mm.
Typical lead time is 2–4 weeks from approved design, depending on complexity. Prototype tooling can be fast-tracked — T1 samples in as fast as 15 days, because machining never leaves our own floor.
Every batch is verified with a spectrometer and shipped with original Mill Test Certificates (EN 10204 3.1). Vacuum heat treatment logs with HRC hardness testing are provided on request.
Yes — stepped profiles, D-cuts, square heads, micro-EDM cavities and internal/spiral water cooling channels per CAD spec, machined entirely in-house on our CNC, EDM and jig grinding floor.
Yes. Every injection mold is trialed on our in-house presses (50–800 T) through T0–Tf milestones, and samples are CMM-verified and approved against your drawing before shipment.
