One Contact In China For Your Machined Parts
Send us your drawing and we handle the rest in China. Drawing review, production coordination, inspection, packing, and delivery to your door.
You talk to one person. We line up the machining processes, the production resources, the quality requirements, and the secondary operations your parts need.
Precision Manufacturing Without The Sourcing Complexity
One team stays responsible for your project from start to finish. Drawing review, production coordination, inspection, secondary processes, packing, and shipment all sit with the same people.
Your parts rarely need one process. Milling, turning, wire EDM, grinding, heat treatment, surface finishing, and precision inspection get arranged around the material, geometry, tolerance, and quantity of each part, instead of forcing every job through one workshop.
- Process route chosen per part, not per workshop
- Tolerance, material, and finish confirmed before production
- One point of contact from drawing to shipment
What We Machine For You
Four core process groups cover most of the parts we quote. Send the drawing and we route it to the process that fits the geometry, tolerance, and quantity.
CNC Milling
Precision milled components, housings, plates, blocks, and complex machined parts in aluminum, steel, and stainless.
CNC Turning
Shafts, sleeves, connectors, threaded parts, and other rotational components, turned and milled in one setup where possible.
Wire EDM
Precision profiles, narrow slots, hardened components, and parts that need tight dimensional control after heat treatment.
Jigs And Fixtures
Custom machining fixtures, assembly fixtures, inspection fixtures, and production tooling built around your own parts.
One Project, One Point Of Responsibility
A machined part often needs more than one process. Milling, turning, wire EDM, grinding, heat treatment, finishing, and inspection can sit with different manufacturing resources.
You do not coordinate any of that. We run the project from drawing review through production, inspection, and shipment, with one contact keeping requirements, revisions, and production stages aligned.
Drawing And Requirement Review
Before production is arranged, we go through the drawing, material, tolerances, critical dimensions, surface finish, quantity, and any special inspection requirements.
If a feature, a tolerance, or a manufacturing requirement needs clarification, you hear about it before the job moves into production, not after the first batch.
Manufacturing Resource Matching
Production is arranged around the actual requirements of your part instead of pushing every project through the same workshop.
Machining process, material, part size, tolerance level, batch quantity, equipment, and any secondary operations all decide where the job runs.
Production And Process Coordination
We follow the project through machining and every secondary process it needs, including grinding, heat treatment, anodizing, plating, and other finishing operations.
Drawing revisions, production status, critical dimensions, and process handoffs stay inside one project, so responsibility never gets split between suppliers.
Inspection, Packing And Delivery
Before shipment the finished parts are checked against your drawing and the inspection requirements agreed at the start.
Inspection records, packing, export documents, and international shipping run through the same contact, so you receive finished parts without managing several manufacturing parties yourself.

A Drawing, A Material, And A Quantity Is Enough To Start
STEP, IGES, or PDF all work. Tell us the material, the quantity, and the tolerances that matter, and you get a quote with manufacturability feedback within 24 hours on business days. If a feature adds cost or needs a second setup, you hear about it before production, not after the first batch.
Checked Against Your Drawing Before It Ships
First article on every new setup, in-process checks on the features that decide assembly, and a final inspection record with the batch. The full process, the equipment and the reports are on the Quality Control page.
