Pressing
The division has one of the largest pressing facilities in India spread across 15 locations. The facility has more than 400 Tandem manual and semi-automated presses ranging from 63T to 2000T presses for highly specialised metal forming operations of varied sizes. All these presses are procured from globally renowned manufacturers.
This robust infrastructure in the pressing facility is used for performing a comprehensive range of sheet metal forming operations including:
- Deep drawing
- Fine blanking
- Blanking
- Impact extrusion
- Piercing
- Embossing
- Ironing and forming from solid, etc.
We also have some special purpose presses equipped with manipulators enabling us to process the material for a wide range of most challenging applications. Intending to take the pressing facility a step ahead, we are already in the process of installing another press line with a capacity of 4000 T.
TWB Facility
We have state-of-the-art Tailor Welded Blanks (TWB) facility that has 2 lines (OYABE SEIKI make) with Welding Length up to 1800 mm. With these capabilities, we create extremely flexible part designs while making sure that the right material is used in the right place.
Coil Blanking Lines
Coil Blanking Line, the heart of the manufacturing operations, produces tight tolerance blanks for manual-fed and robotic-fed downstream operations, including stamping, roll-forming, punching and notching, wing bending, or a combination of these operations. Blanking lines offer the complete manufacturing process – from the coil to the blank stack – from a single source.
These lines automatically manufacture simultaneously from the coil to the blank stack: inserting materials according to mould types, adjusting product length and width, and stacking sheets with oscillating shear.

High Tensile Sheet Metal Stamping Technology
With increasing environmental and legislative demands for higher levels of fuel emission standards, performance standards, and versatility, automobile manufacturers are increasingly focusing on structural and body inners in high tensile materials (ferrous alloys and also nonferrous alloys) in thinner sections. Auto majors in India are now actively focusing on this technology to meet and sustain legislative demands (Euro V / equivalents and other regulatory standards), getting enforced from 2018-19 and more stringent regulations on Vehicle Safety (especially in Passenger Car segments).
Models of Passenger Vehicles launched in India, from 2016-17 have an increasingly greater content of members in higher tensile steels (UTS >/= 590MPa). Forming on High tensile ferrous alloys (Steel) is more complex due to their inherent high yield points and low formability. At Caparo, this is undertaken in both hot stamping and cold forming (stamping) methods.
The world over, forming on higher tensile Steels (up to ~ 980 MPa Tensile strength) is undertaken by Cold Forming. However, Tool Development for such Tools involves much higher levels of Structural Design and Manufacturing Technology.
- Operation on such Dies requires a greater level of process technology.
- The current level technology at Caparo Stamping Units is adaptive to manufacture stamped panels to UTS 590 MPa.
- Steels with higher Tensile Strengths (UTS > 1000 MPa) are generally processed by Hot Forming.
