Metalworking processes

CNC machining

CNC machining removes material with computer-controlled mills, lathes and machining centres to produce highly accurate parts. It is fundamental in metalworking because it combines repeatability, tight tolerances and flexibility, from prototypes to serial production.

Select “CNC machining” when creating the RFQ, then add the material, quantity, tolerances and technical drawing.

Metal fabrication

Metal fabrication turns sections, tubes and plates into frames, supports, guards and complete structures through cutting, forming, welding and assembly. It is essential because it connects individual metal components into robust, production-ready equipment and constructions.

Select “Metal fabrication” when creating the RFQ and describe the structure, materials, dimensions, welds, finishes and required certifications.

Sheet metal

Sheet-metal processing uses laser or plasma cutting, punching, bending and rolling to transform flat sheets into precise parts and enclosures. It is central to metalworking because it enables lightweight, repeatable and cost-effective components across machinery, automotive and industrial products.

Select “Sheet metal” when creating the RFQ and specify sheet grade and thickness, quantities, cutting method, bends, holes and surface finish.

Stamping & dies

Metal stamping forms or cuts sheet with presses and dedicated dies through blanking, drawing, bending and progressive operations. It is fundamental for high-volume production because it delivers fast cycle times, consistent geometry and a low unit cost once tooling is in place.

Select “Stamping & dies” when creating the RFQ and include the part drawing, material, sheet thickness, annual volumes and whether a new die is required.

Castings

Casting pours molten metal into a mould to create shapes that would be difficult or expensive to machine from solid stock. Sand, investment and die casting are vital to metalworking because they make complex geometries, large parts and efficient series production possible.

Select “Castings” when creating the RFQ and state the alloy, casting process if known, expected volumes, machining allowances and quality requirements.

Surface treatments

Surface treatments such as zinc plating, anodising, painting, nickel plating and blackening modify or protect the outer layer of a component. They are fundamental because they improve corrosion resistance, wear behaviour, appearance and service life without redesigning the part.

Select “Surface treatments” when creating the RFQ and identify the base material, treatment or required performance, dimensions, appearance and applicable standard.

Assembly & welding

Assembly and welding permanently or mechanically join fabricated and purchased components into subassemblies or finished products. They are indispensable in metalworking because final quality depends on alignment, joint strength, process control and reliable integration of every part.

Select “Assembly & welding” when creating the RFQ and provide the bill of materials, drawings, weld specifications, inspection criteria and required assembly level.
