Die Casting Lubricants
Die casting product quality and productivity improvement
Die casting is a casting method where molten metal is poured into a mold at high pressure and hardened. “GRAPHACE” is the die casting lubricant necessary for the separation of the heated metal from the mold. It is used on die casting machines used to cast aluminum automotive parts and magnesium parts and it contributes to the improvement of productivity and the environment.
Water-soluble minimum quantity spray type lubricant
This product is not diluted, so it is extremely stable. Only a very small amount is applied, so the waste liquid is reduced and the longer mold life achieved means that it has the effect of reducing production costs. The air blowing time can also be reduced, so it contributes greatly to the improvement of the cycle time.

Water-soluble diluted type (High releasing properties)
These products can form a good mold release film even if the mold temperature is high, so they have the greatest ability to prevent the adhesion of the product to the mold surface. They can be used to improve productivity in a variety of ways, including by reducing the machine cycle and by only applying a small amount.
