CASE STUDY – DIE CASTING
An automotive parts manufacturer was looking to replace the water glycol (HFC) fire-resistant hydraulic fluids being used to operate their die casting equipment. The fluid being used:
- Had the typical lubricating properties of water glycol fluids
- Pump wear and pump lifetime were unacceptable to this manufacturer
To help improve operations, the manufacturer tested QUINTOLUBRIC® 888 polyol ester (HFD) fluids as a potential replacement.
First, Quaker helped the manufacturer to understand the advantages of changing from water glycol (HFC) fluids to polyol ester (HFD-U) fluids. These advantages include:
- Superior lubrication properties
- Easier waste treatment/waste disposal/reclamation
- Lower vapor pressure
- Reduced fluid maintenance
- Inherent fire propagation resistance
- Environmentally friendly
- Improved corrosion protection
Although HFD-U fluids can cost up to 1.5 – 2 times the cost of HFC fluids, the reduction in pump wear and waste treatment costs that a manufacturer can experience with HFD-U fluids more than makes up for the initial cost difference. HFD-U fluids are lighter than water, which allows them to be removed from waste water streams by skimming. HFD-U fluids are much easier to remove during waste treatment processes than HFC fluids, which significantly reduces a manufacturer’s cost and waste.
