LO-402 / 409 Stamping Oil: Heavy-Duty Solution for Steel & Stainless Steel – Comprehensive Mold Protection
In medium-thickness carbon steel and stainless steel (Inox) forming processes, the pressure exerted on the die surface and workpiece is very high. Using stamping oil with insufficient lubrication levels will lead to die burning or surface scratching of the part. Heavy duty stamping oil LO-402 / 409 from the brand TP Oil is a technical solution that thoroughly addresses these challenges.
1. Specialized Extreme Pressure (EP) Technology for Hard Materials
Unlike light-duty processing oils, LO-402 / 409 is fortified with a high content of extreme pressure (EP) additives and anti-wear agents. When the stamping punch impacts the INOX workpiece – which has high hardness and ductility – the oil film of LO-402 / 409 maintains its tough and resilient strength, preventing direct metal-to-metal contact and ensuring a smooth deformation process.
2. Outstanding Advantages of TP LO-402 / 409 Stamping Oil
This product is an invaluable assistant for progressive stamping lines:
-
Excellent medium load-carrying capacity: Effectively protects punches and dies in blanking and shallow drawing operations on iron and stainless steel workpieces of moderate thickness.
-
Anti-sticking and anti-scratch: Eliminates the phenomenon of Inox workpiece sticking to the die surface (galling), ensuring finished parts have a smooth, glossy surface with sharp contours.
-
Extended tool life: Reduces thermal friction and mechanical wear, allowing expensive die sets to have a longer operational lifespan and lowering maintenance costs.
-
Fast heat dissipation: Helps lower the temperature in the processing area, preventing thermal deformation of the part and protecting the material structure.
-
High stability: The oil has low volatility, does not produce unpleasant odors, and provides temporary rust protection for the product after processing.
