Cold Forging of Steel – Durable, High-Precision Components
Steel is the foundation of many essential components. But only cold forging unlocks its full potential: precise, resilient, and chip-free parts, formed directly at room temperature. No material waste, no laborious reworking – instead, maximum dimensional accuracy and repeat precision. Whether for machine construction, drive technology, or medical technology: Walter Schneider shapes your steel – economically, durably, and at series level.
Why Cold Forging Is Ideal for Steel
Maximum Strength through Work Hardening
During cold forging, the material is plastically deformed under pressure without disrupting the grain structure. Especially with steel, this leads to an additional hardening of the structure – the components are not only shaped but also become more stable and durable. Ideal for safety-relevant or highly stressed components.
Tight Tolerances and High Repeatability
Even with millions of pieces, the dimensions remain exactly reproducible. The closed tooling produces dimensionally stable components with the closest tolerances – if necessary in the hundredths range. This is a major advantage, especially for press-fit, sealing, or bearing connections.
Full Material Utilization
Unlike milling or turning, no material is removed during forging. This means: no cuttings, no waste, 100% of the raw material is utilized. Especially with high-priced noble or automatic steels, this results in a significant economic advantage.
Less processing, Shorter Process Chain
Extruded steel parts often come out of the machine in ‘near-net-shape’ – almost in final form. Complex rework or machining is often unnecessary or limited to simple calibration. This saves time, energy, and production costs.
Suitable for Complex and Asymmetrical Geometries
With multi-stage forming processes, even complex geometries, transverse holes, or varying wall thicknesses can be achieved – without additional welding, drilling, or joining. Non-rotationally symmetrical or functionally integrated parts are also possible.
Your Advantages With Cold Forging of Steel
-
Maximum Strength & Durability
Cold-formed steel parts are significantly stronger and more durable than machined parts – due to continuous fiber flow and material densification. -
High Dimensional Accuracy and Repeat Precision
Even in high-volume production, form and tolerances remain consistent – ideal for assembly or safety parts. -
Less Processing – Lower Costs
Many parts come nearly finished from the tooling – turning, milling, or grinding are unnecessary. -
Process Stability & Economically Viable for Large Series
Our presses produce with high automation – ideal from about 50,000 pieces/year. This reduces unit costs and accelerates delivery times.

Typical Concerns About Cold Forging of Steel – and Why They’re Unfounded
"But steel is too hard to cold form!"
Answer: Only with the right technique. Walter Schneider uses high-performance presses, specially developed tools, and matched lubrication strategies to reliably press even high-strength steels.
"It requires extremely high forming forces – isn’t that expensive?"
Answer: Tooling costs are incurred once. After that, series production runs fully automated, stable, and with low unit costs – significantly cheaper than machining or casting.
"We have very tight tolerances – that’s only possible with milling."
Answer: Cold extrusion achieves tenth to hundredth tolerances – and with a significantly shorter production path and higher repeatability.
"Our geometry is too complex for flow forming."
Answer: We combine forward, backward, and cross extrusion in multiple stages – even asymmetrical shapes or function integration are possible.
