Metal Parts Sourcing
from China
CNC machined components, fabricated assemblies, sheet metal, castings and stamped parts — sourced, inspected and delivered to the UK. Manufacturing support from engineering drawings through to inspection and UK delivery.
A UK sourcing agent that understands engineering
Sauce Asia has been sourcing metal parts from China for UK businesses since 1999. We work directly from engineering drawings, CAD files and specifications — not from product descriptions or samples alone.
Our team includes engineers and quality inspectors based in China. We identify manufacturers capable of meeting your tolerances and finish requirements, manage production and carry out inspection before any shipment leaves the factory.
We work with UK engineering companies, manufacturers, distributors and OEMs. Projects range from prototype quantities and small production runs through to high-volume container shipments.
Metal parts we source from China
We work across all major metal manufacturing processes. If your parts require a combination of processes, we identify manufacturers with the right capabilities under one roof.
CNC Machined Parts
Turned and milled components from engineering drawings. Required tolerances are assessed against the customer's drawing and the selected manufacturer's verified capability. Materials including steel, aluminium, brass and engineering plastics.
Metal Fabrication
Welded assemblies, structural frames, brackets and enclosures. MIG, TIG and spot welding. Powder coat, zinc plate and paint finishes.
Sheet Metal Components
Laser cutting, punching, bending and forming. Mild steel, stainless and aluminium. Prototypes through to production volumes.
Castings & Forgings
Die casting, investment casting and sand casting. Steel and aluminium forgings. Machining and finishing in-house at the same facility.
Stamped & Pressed Parts
Progressive die stamping, deep drawing and fine blanking. High-volume runs with consistent dimensional accuracy.
Assemblies & Sub-Assemblies
Multi-component assemblies combining machined, fabricated and bought-in parts. Tested and packed to your specification.

Quotation & Review
We obtain competitive quotations and review them with you. We highlight any technical concerns before you commit.
Production & Inspection
We monitor production and carry out inspection before shipment. Dimensional checks, visual inspection and functional testing as required.
Shipping & Delivery
Sea freight, air freight or express courier. We handle documentation, customs clearance and UK delivery.
Inspection before every shipment
We can arrange appropriate in-process and pre-shipment inspections for metal-parts orders, based on the product, risk and agreed inspection scope.
We provide a written inspection report with photographs. If parts fail inspection, we manage the rework or replacement process with the manufacturer — before the shipment leaves China.
