(1) Due to the fact that silicon steel plate is a material that is relatively easy to stretch, low viscosity stamping oil is chosen to ensure easy cleaning of the finished workpiece while preventing scratches.
(2) When selecting stretching oil for carbon steel plates, the optimal viscosity should be determined based on the process difficulty and degreasing conditions.
(3) Due to the chemical reaction with chlorine based additives, attention should be paid to the possibility of white rust when using chlorine based stretching oil for galvanized steel plates, while using sulfur based stretching oil can avoid rusting.
(4) Stainless steel is a material that is prone to hardening, requiring the use of tensile oil with high oil film strength and good sintering resistance. Generally, stretching oil containing sulfur chlorine composite additives is used to ensure extreme pressure performance while avoiding problems such as burrs and fractures in the workpiece.
