Your drawing, our workshop
Many manufacturers prefer not to keep every process in-house. We take over the production of metal parts and welded assemblies to your drawings and deliver them in the quantities you need — as a single batch or as recurring orders.
Because we build complete concrete batching plants, our workshop is used to reading complex drawings and keeping parts consistent from one piece to the next.
From sample to repeat production
We review the drawing and material, agree the batch size and schedule, and can make a first sample for your approval. Once it is approved, each batch is produced to the same drawing and checked before it leaves the workshop.
What to send for a quote
The drawing or CAD file, the material, the quantity per batch, the expected yearly volume if the order repeats, and your delivery schedule.
