# Cold-forming lubrication

Graphite coating for cold stamping, deep drawing, and bending: it forms an even lubricating film between die and sheet.

Family: Lubrication applications

## Description
Cold drawing and bending fail because of friction: the sheet scores, marks, or tears when it does not slide evenly against the die. A dry graphite film spreads the sliding across the whole contact area and leaves the part clean, without the oily residue that later has to be degreased.

## Selection and application

Sheet thickness and forming severity set the dilution and whether to coat the die, the blank, or both. Apply by brush, roller, or spray onto a clean surface. ESGRAF supplies GRAFOPLATE for cold stamping, drawing, and bending of metals.

## Processes
- Stamping
- Deep drawing
- Bending
- Cold forming

## Challenges
- Sheet scoring and marking
- Sticking to the die
- Tearing from excess friction
- Residue that forces degreasing

## Advantages
- Dry drip-free film
- Reduces friction and marking
- Non-flammable water-based version
- Eases part release

## Limitations
- Does not replace stamping oils in severe operations
- Requires a clean surface
- May stain light-colored surfaces
