Improving heading processes
27 September 2016
Among a wide range of lubricants dedicated to the requirements of cold heading machinery, CONDAT will present new solutions to provide high duty lubrication with optimum safety at Fastener Fair Italy.
The weight reduction in automotive and aeronautic markets has pushed the fastening industry to use new materials. Titanium, inconel, stainless and high strength steel are now commonly used but their forming properties are weak. To reach high productivity, it is necessary to warm the wire before the heading process from 250°C up to 900°C.
For technical parts, with forming ratio higher than 70% and massive parts with wire diameter bigger than 20mm, the internal temperature can easily reach 250°C due to significant material flow. In both cases, the lubricants must be designed to work at very high temperature. From 250°C to 900°C, CONDAT offers solutions to improve processes:
- For temperature up to 250°C – EXTRUGLISS warm green oils avoid degreasing issues due to sticky and burned residues which occur at such temperature.
- For preheated wire up to 500°C – EXTRUDEX warm forming lubricants benefit from high thermal stability, which enhance lubricity performances. They are safe for the workshop environment as they reduce smokes and mist.
- For preheated wire up to 900°C – EXTRUDEX hot forming oils are specifically designed for the aerospace market to work on titanium and nickel alloys. They allow a homogeneous coating on the parts for optimum surface finish and no deposits on dies and punch. These safe lubricants present a very high flash point to reduce the risk of fire.
- For lubrication of the cold forming machinery – GLISS warm green lubricants are specifically formulated to reduce cross contamination issues and keep the long-term performances of CONDAT’s heading oils. Available now from 68cst – 220cst viscosity.
