Stretching oil selection

  • (1) Since silicon steel plate is a material that is relatively easy to stretch, low-viscosity stamping oil will be used on the premise of preventing scratches for the easy cleaning of the finished workpiece.
  • (2) When selecting drawing oil for carbon steel plates, the best viscosity should be determined according to the process difficulty and degreasing conditions.
  • (3) Because of the chemical reaction with chlorine-based additives, when choosing drawing oil for galvanized steel sheets, attention should be paid to the problem of white rust that may occur with chlorine-type drawing oil, and the use of sulfur-type drawing oil can avoid the problem of rust.
  • (4) Stainless steel is a material that is prone to hardening, and it is required to use drawing oil with high oil film strength and good sintering resistance. Generally use sulfur-chlorine compound

    The stretching oil of the combined type additive can avoid problems such as burrs and cracks on the workpiece while ensuring the extreme pressure performance.
