Manufacturing Capabilities

From drawing to mass production — a one-stop partner for tube parts and industrial supply

How We Work

A standard five-step process with full traceability at every stage.

01

Send your drawing

Upload a 2D drawing or 3D file, or send a sample, with material, quantity and target date.

02

Engineering review & quote

Our engineers confirm manufacturability, material and tolerance, and return price and options within one business day.

03

Sample & approval

Receive samples for approval; adjust dimensions, surface treatment and packaging as needed.

04

Mass production & QC

Production, full inspection and dimensional report, shipped with material certificates and test files.

05

Export delivery & support

Shipped on FOB / CIF / EXW / DDP terms with continuous follow-up and after-sales support.

Drawing-based tube part machining

Send us a 2D drawing, 3D file or a physical sample. Our engineers review manufacturability, confirm material and tolerance, then quote — usually within one business day. We work with carbon steel, stainless steel (304/316L/TP321), aluminium alloy, copper and special alloys.

Process capability

  • CNC turning and milling for tube fittings and flanges
  • Bending, drilling, riveting, stamping and welding
  • Multi-axis machining for complex special-shaped parts
  • Surface treatment: zinc plating, passivation, anodising, powder coating, sand blasting
  • Assembly of complete sub-assemblies per customer BOM

Quality control

Incoming material inspection, in-process checks and final dimensional reports with CMM support. Material certificates (EN 10204 3.1/3.2), salt spray, hardness, tensile and torque tests available on request.

One-stop supply

Beyond machined parts, we source and consolidate the consumables your production line needs — abrasives, cutting tools, bearings, motors, valves, electrical materials, PPE and MRO items — so you receive one consolidated shipment and one commercial contact.

Commercial terms

  • Low MOQ accepted for trial orders
  • FOB, CIF, EXW and DDP terms
  • Export-standard cartons, steel pallets and custom branding
  • Sample orders, pilot batches and annual framework agreements
