About WenCNC
An engineering-first machining partner for product teams
WenCNC is set up as one workshop rather than a chain of subcontractors: machining, sheet metal, finishing and inspection are planned together, and one engineer stays with the part from the first review to the delivery document.
That matters most on the parts that are hard to make — thin walls, tight datums, cosmetic surfaces and finishes that have to match across shipments.
- Engineering review before quoting, not after the order
- Prototype and production parts made on the same process
- Finishing and inspection handled inside the same order
Why WenCNC
Why customers keep their parts with us
Most projects fail on communication, not on machines. We keep engineering close to the shop floor so design questions are answered before the chips are made.
Engineering review before machining
Every RFQ is reviewed by an engineer for manufacturability, tolerance cost and material alternatives, so you know where the cost is before you commit.
Prototype to production continuity
The same process, fixtures and inspection plan scale from 1 piece to low-volume runs, so the part that passes validation is the part that ships.
Tight tolerance control
Parallel-machined fixtures and in-process inspection on 3, 4 and 5-axis centres hold accurate datums across the batch.
Wide material availability
Aluminium, stainless steel, carbon steel, brass, copper, titanium and engineering plastics are sourced against your specification, with certificates on request.
Finishing in the same supply chain
Anodizing, powder coating, plating, polishing and painting are managed together with machining, so colour and appearance stay consistent between batches.
Clear communication
One English-speaking contact for quoting, engineering questions, production status and shipping documents — with proactive updates when something changes.
How it works
From RFQ to delivery in five steps
Upload a drawing or 3D model and we will come back with a quotation, lead time and any engineering questions.
