What is Hot Stretch Forming

Hot Stretch Forming (HSF®) is an innovative forming process developed by Cyril Bath in collaboration with Aerospace leading OEMs (Original Equipment Manufacturers) that combines closed loop-controlled heating with traditional force and position-controlled Stretch Forming to straighten and form contoured titanium profiles into complex aerostructures. This patented technology utilizes extrusion, rolled shape and bar raw materials, in a variety of cases as an alternative to “traditional” manufacturing raw materials such as plate or forging and was strategically developed as an overall means to reduce total part cost via titanium consumption, subsequently reducing milling and assembly costs. It is also proven that there is a direct cost reduction in logistic flows.

Materials

The process is primarily used for titanium, and nickel-based alloys.

Industries

Our formed parts meet the high standards of the aerospace and defense industries, where performance, reliability, and precision are essential.
Our expertise can also be applied to other cutting-edge sectors that require contoured profiles.

Applications in the aerospace industry

Shaping the Future of Aircraft Structures
Production cost improvement: The buy to fly ratio

Shaping the Future of Aircraft Structures

Thanks to our patented HSF® technology and decades of expertise, we manufacture aerospace structural parts that meet the most stringent requirements. Our industrial capabilities enable us to mass-produce transversal and longitudinal fuselage and nacelle parts. With more than 20 years of proven production and process compliance with Boeing specification BAC5300 and Airbus specification AIPS & AIPI 03-10-011, we’ve produced over 100,000 flying parts.
The main applications of HSF® are:
Replacement of machined parts nested in plates by HSF® pre-forms

Replacement of a forging by an HSF® pre-form
Replacement of an assembly of several parts machined from forged or plate by one HSF® pre-form
Production of several different PNs from one HSF® pre-form
Production of several identical PNs from one HSF® pre-form

Production cost improvement: The buy to fly ratio

The buy to fly (BTF) ratio is a term used primarily in the aerospace industry to describe the efficiency of material usage in manufacturing. It is defined as the weight of the raw material divided by the weight of the final component. A lower BTF ratio indicates more efficient use of material, as less waste is generated during the manufacturing process. With the cost of Titanium, a decrease in overall raw material usage can be extremely valuable from a cost standpoint.
The main benefits of the HSF process:
Significant improvement of the “Buy to Fly” ratio typically improving from 8:1 with plate and forgings to 3:1 with the HSF pre-forms and forming process.
Significant reduction of milling time: Average reductions are more than 50%
Increased overall cost reductions: 20 to 50% lower
Potential collateral improvement: Assembly time reduction, flying weight reduction, reduced number of parts, etc.
