Meco Forging Parts Process
Meco’s forging expertise includes both hot forging and cold forging, enabling us to deliver components with unmatched strength, precision, and durability.
Hot Forging
Performed above recrystallization temperature. Ideal for larger parts and intricate designs requiring maximum formability.
- Materials: Carbon/Alloy Steel, Aluminum, Brass
- Best For: Structural parts (axles, shafts)
- Industries: Automotive, Aerospace, Oil & Gas
Cold Forging
Performed near room temperature. Increases hardness via work hardening for tighter tolerances and superior finish.
- Materials: Carbon/Alloy Steel, Aluminum
- Best For: Fasteners, pins, small gears
- Benefits: High precision, surface finish
Forging FAQ
What is the main advantage of forging over casting?
The primary advantage is superior mechanical strength. The forging process refines the metal’s grain structure and aligns it with the part’s shape, eliminating the porosity and potential defects found in castings. This results in parts with significantly higher tensile strength and fatigue resistance.
Which is better: hot forging or cold forging?
It depends on the application. Hot forging is ideal for creating larger, more complex parts. Cold forging is better for smaller parts where dimensional accuracy, a smooth surface finish, and increased hardness are the primary goals. Our engineers will help you choose the best method.
What tolerances can forging achieve?
As-forged tolerances vary by process (cold forging is tighter than hot forging). However, MECO’s turnkey advantage is our in-house CNC machining. We use the forging process to create a strong, near-net-shape blank, then machine critical features to tolerances as tight as ±0.01 mm.
What materials can Meco forge?
We forge a wide range of metals, including various grades of carbon and alloy steels, stainless steels, aluminum alloys, brass, and copper to meet your specific application requirements.
How to Get Started
Upload your 3D CAD models (STEP/IGES) and specify material, quantity, tolerances, and any surface finish or inspection requirements.
Engineering reviews your design for forgeability, optimizing die design and process parameters to balance cost, cycle time, and dimensional accuracy before issuing a quote.
Custom dies, preform shapes, and process parameters are prepared, and the forging workflow (heating, forming, trimming) is validated for consistent quality.
Parts are forged, heat-treated, and machined to final specifications, with dimensional inspections and material traceability provided before packaging and shipment.
