Warm/hot forming lubricants

The weight reduction in automotive and aeronautic markets have 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. The lubricants must be designed to work at very high temperature. From 250°C to 900°C, Condat offers solutions to improve the process. For temperature until 250°C, EXTRUGLISS Warm Green oils avoid degreasing issues due to sticky and burned residues which occurred at such temperature. This range, based on renewable chemistry, can be used also for lubrication of press. For preheated wire until 500°C, EXTRUDEX warm forming lubricants benefit from high thermal stability which enhance lubricity performances. Friendly for operators and safe for the workshop environment as they reduce smokes and mist. For preheated wire until 900°C, EXTRUDEX hot forming oils are specifically designed for 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 68 to 220 cst viscosity.

New lubricants for steel tubes

condatAt Tube Düsseldorf, Condat will present its new lubricants developments for tube processing. One of those are the reactive soaps COLLUBE range. These soaps combine with the phosphate layer deposited on the tube in order to create a chemically bonded lubricant film. It therefore allows deformation under optimum conditions, increases reduction possibilities, and results in a perfect surface finish even under severe conditions (heavy reduction, high drawing speed…. CONDATUB TFH is perfectly suited for direct drawing on bare or pre coated metal surfaces. Due to their optimum formulation (high performance based oil + extreme pressure additives), they perform in high duty drawing operations whilst minimizing tool wear. Different viscosity levels are available to respond to different deformation requirements, allowing optimal surface finish and cleaning ability (some formulations are designed to vanish during heat treatment operations. Promoting an eco-responsible policy, Condat’s R&D department accommodates the latest regulations and focuses on developing safer products for both people and the environment, without compromising on performance. Several production sites, all ISO 9001 certified, enable Condat to deliver top quality products everywhere in the world through its distribution & service network.
