Due to the complexities of the die casting production process, proper die lubricant selection can be a laborious task.
Cutting and grinding coolants, diluted for use, are mostly water (95% water at a typical concentration). Water plays an important role in coolant performance. We need to understand how water affects metalworking coolants. This “Skill Builder” makes water crystal clear.
Quaker manufactures and sells fire resistant hydraulic fluids (FRHFs) under the brand name QUINTOLUBRIC®. Routine analysis of these fluids is sent to Quaker laboratories in Conshohocken, PA to the Q-TRAK lab. This lab assesses the FRHFs in a number of areas as detailed in this “Skill Builder.”
One of the most important process variables in die casting is the dilution ratio. The dilution ratio is the ratio at which a die lubricant is diluted in water prior to being sprayed onto the die. Unfortunately, there is no one optimal dilution ratio, as this is something that must be established based on each unique application and die cast machine.
