What is Hot Forming ?

Hot Forming is a process that enables the production of titanium parts, simple or complex, in a fast, cost-effective, and industrial manner. This technology combines dimensional precision, high mechanical performance, and production rates adapted to the requirements of cutting-edge industries.

The Process Principle

The metal sheet is heated to 700°C and then positioned between a punch and a refractory steel die. The punch descends progressively and applies force of several tens to hundreds of tons to shape the part. Controlled pressure holding, locks the geometry by releasing internal stresses: the part retains its shape after cooling, with minimal springback.

Key technical point: elongation and thickness reduction are limited in this process. In practical terms, the material does not become excessively thin and local elongation remains controlled. Result: more uniform thicknesses, no areas weakened by excessive thinning, and parts that retain high mechanical properties (fatigue resistance, mechanical strength).

Industrial Advantages

High productivity: short cycles from 10 minutes to 1 hour depending on geometry and material
Simultaneous production: multiple parts formed in the same tooling
Excellent repeatability: guaranteed quality consistency for industrialization
Cost reduction: approximately 50% savings compared to SPF
Energy efficiency: reduced energy consumption

Hot Forming equipment and technologies

Hot Forming machines: configuration and capabilities

Hot Forming presses are specialized equipment designed to operate under extreme thermal and mechanical constraints. They may integrate several critical systems:

Heating systems: sheet preheating furnaces with fine thermal regulation to guarantee temperature homogeneity and material properties.
Hydraulic or mechanical presses: capacities ranging from a few tens to several hundreds tons of force, with precise control of punch descent speed and pressure holding.
Refractory tooling: dies and punches in special steels resistant to high temperatures and repeated thermal cycles, custom-designed for each part geometry.
Controlled cooling systems: to control cooling rate and optimize final metallurgical properties.

Numerical simulation: guaranteeing conformity from design

Finite element simulation plays a crucial role in hot forming optimization. It enables prediction of:

Stress and strain distribution
Stress concentration zones
Final thicknesses after forming
Springback
Optimal process parameters (temperature, speed, pressure)

This numerical approach significantly reduces physical iterations and accelerates new tooling development.

Superplastic Forming: principle and characteristics

Superplastic Forming (SPF) exploits the ability of some metal alloys to undergo extreme deformations (up to several hundred percent elongation) without rupture, when heated to specific temperatures and deformed very slowly.

How does the superplastic process work?

SPF relies on a deformation mechanism at the scale of metal grains: at high temperature (generally between 850°C and 950°C for titanium alloys) and under low strain rate, the grains slide relative to each other rather than deforming plastically. This phenomenon enables exceptional elongations reaching 500% to 1000%.

The process typically uses inert gas pressure (argon) to progressively press the sheet against a die. The strain rate is extremely slow – the complete cycle can take several hours – but allows the creation of very complex geometries with deep drawing depths.
