High Performance Special Forming Fluids

High Performance Special Forming Fluids

Extreme surface pressures and specific frictional forces are critical aspects that effect tool and work piece in a metal forming process. Knowledge of distribution of contact stresses and friction coefficients over the die surface is critical in formulating the right lubricant that has perform under demanding conditions.

BECHEM is a leading worldwide producer of high performance special forming fluids and release agents for various forming processes. Apart from high quality wire drawing fluids, BECHEM also develops forming fluids for forging process, tube drawing process as well deep drawing and punching processes.

Collaborating with end users machine and tool manufacturers, BECHEM has developed the next generation metal working fluids for the entire spectrum of metal working processes.

The wire drawing lubricants of BECHEM Unopol and Berudraw series belong to the leading global brands in wire production and processing.

Through continuous research and development BECHEM ensure the highest level of quality and productivity for all applications in the demanding field of wire production.

Extreme surface pressure between tool and work piece require high performance parting agents which are able to build up pressure resistant layers during the cold forming process such as punching and blanking in order to prevent premature wear, fretting or even breakage of the tools.

With extensive experience in developing speciality lubricants, BECHEM has developed high performance lubricants for the severe operation of tube drawing process.

Greases are made by mixing a solid material, called a thickener, with a base oil and property enhancing additives; but it’s the oil that forms the lubrication film. For better understanding, grease thickener can be thought of as a sponge saturated with oil. Moving parts squeeze the oil out of the sponge like thickener for forming the lubrication film. Typically, the base oil constitutes the largest proportion of grease weight at about 80-90%, followed by thickener at 10 to 20% and additives under 10%.

Dropping point of a lubricating grease is an indicator of the heat resistance of the grease. and is the temperature at which the grease is no more a thickened lubricating medium. The dropping point indicates the upper temperature limit at which a grease retains its structure, not the maximum temperature at which a grease may be used.

Few greases have the ability to regain their original structure after cooling down from the dropping point.

The most important feature of a grease is its consistency. A grease that is too stiff may not get pumped into areas requiring lubrication. While a grease that is too fluid may leak out. Grease consistency depends on the type and amount of thickener used and the viscosity of its base oil. A grease consistency is its resistance to deformation by an applied force.

The measure of consistency is called penetration. Penetration depends on whether the consistency has been altered by working. Standard test procedures established by American Society for Testing and Materials International (ASTM) and accepted by industry are ASTM D 217 and D 1403, measure penetration of unworked and worked greases.

The NLGI has established consistency numbers ranging from 000 to 6, corresponding to specified ranges of penetration distance of the standard cone into the test grease. Table below lists the NLGI grease classifications along with a description of the consistency of each classification.

Viscosity: It is a measure of resistance to flow of a lubricating oil.

Viscosity index: It is defined as rate of change of viscosity with respect to temperature.


  • It is the most important property which determines the performance of lubricating oils under the influence of temperature
  • A lubricating oil should have sufficient viscosity to retain a lubricating film on the surface
  • On machine part moving at slow speeds under high pressures, a high viscous oil should be used as it better resists being squeezed out from between the rubbing parts.  Light oils can be used for lower pressures and high speeds.
  • It is not possible to maintain a liquid oil film between two moving or sliding surfaces if the viscosity is too low and hence excessive wear will occur.

The pour point of an oil is the minimum temperature at which the oil turns into semi solid and almost losses its flow characteristic. At low temperatures, the viscosity of the oil will be very high, causing the oil to resist flow. This is important in equipment that operates in a cold environment or handles cold fluids.
