A drawing is only the starting point. The real risk comes when design details, fabrication, welding, finishing and packing are handled separately. See how Yishang coordinates the steps that turn your drawing into a finished metal product ready for delivery.
We review critical dimensions, holes, mounting points, weld areas, visible surfaces and assembly interfaces before production begins.
Cutting, forming, welding, machining and finishing are coordinated around the same drawing and product requirements to reduce handoff errors and rework.
Quality is controlled through IQC, IPQC and OQC, with 100% final inspection of critical dimensions, fit, appearance, quantity and packing before shipment.
