Press Forging
Press forging applies slow, continuous squeeze rather than repeated impact. The deformation reaches the core of the section instead of concentrating at the surface, which matters enormously on thick parts where hammer blows alone leave an unworked centre.

Through-Section Deformation
A press stroke of controlled speed keeps the metal plastic for longer, so strain penetrates fully through heavy sections. On flange and hub-type parts above 60 mm thickness this is the difference between uniform properties and a soft, coarse-grained core.
Repeatability You Can Put on a Control Plan
Stroke is mechanically fixed, so every piece receives the same reduction. Weight variation typically stays inside ±2%, cavity fill is consistent, and Cpk on critical forged dimensions holds above 1.33 — the reason automotive customers prefer presses for PPAP parts.
- Fixed stroke, repeatable reduction
- Weight variation within ±2%
- Cpk above 1.33 on forged features
- Automated part handling
Quieter, Safer, Better for Die Life
Presses transmit far less shock into the foundation and the tooling. Die life on press-forged production commonly runs two to three times longer than the equivalent hammer die, and the working environment is markedly quieter.
Squeeze Versus Impact: What Changes Inside the Part
A press applies force over a stroke rather than delivering energy in an instant. The metal stays plastic for longer, so strain penetrates the full section instead of concentrating near the surface. On parts thicker than roughly 60 mm — hubs, heavy flanges, crankshaft webs — this is the difference between uniform properties throughout and a coarse, lightly worked core that no external inspection would reveal.
- Deformation reaches the core of heavy sections
- Mechanically fixed stroke gives repeatable reduction
- Weight variation typically within ±2%
- Far less shock transmitted into tooling and foundations
Repeatability You Can Put on a Control Plan
Because the stroke is mechanically fixed, every piece receives the same reduction. That produces the statistical behaviour automotive customers require: consistent forged weight, consistent cavity fill and process capability above Cpk 1.33 on forged characteristics. It also extends die life, commonly two to three times that of an equivalent hammer die, because the tooling is not absorbing repeated impact. See Cpk and what is PPAP.

People also ask
Why does press forging give better properties on thick parts?
A press stroke keeps metal plastic for longer, so strain penetrates fully through heavy sections instead of concentrating near the surface as hammer energy does.
What weight consistency does press forging achieve?
Within ±2% forged weight, with process capability above Cpk 1.33 on forged characteristics.

Questions Answered
Press forging or drop forging — which should I choose?
+
Choose press forging for thick sections, tight weight control and automotive volume work. Choose drop forging for mixed-model batches, generous geometry and lower die investment.
Does press forging give better mechanical properties?
+
On heavy sections, yes, because strain reaches the core. On thin parts the two routes give comparable properties.
What press capacity do you operate?
+
Our friction screw and hydraulic presses cover the range needed for components up to 75 kg finished weight.
Can you run PPAP-level documentation?
+
Yes. PPAP, control plans, PFMEA and dimensional layouts are prepared for IATF 16949 customers as standard.
