Die Release Agents and Plunger Lubricants
Die release agents and plunger lubrication beads for HPDC
Overview
What it is and where it works
Die release agents sprayed on the die between shots to release the casting and protect the die surface, and plunger lubrication beads that protect the tip and shot sleeve in cold chamber machines. These two are the industry standard: release agents are mostly water-based dilutable emulsions, and beads are wax carrying graphite or white pigments. We source by alloy, machine and dosing system.
- Die release
- Water-based dilutable or water-free grades for aluminium, magnesium and zinc
- Plunger beads
- High-melting synthetic wax with graphite or white pigments, bead sizes from about 0.2 to 3 mm
- Plunger operation
- The plunger should run about 20 °C above the wax congealing point for beads to spread

Frequently Asked Questions
Why plunger beads?
Beads dose dry with little residue and can be dispensed automatically, which is why they are the industry standard for plunger lubrication.
Can plunger lubrication affect tip life?
Yes. If the lubricant breaks down at higher metal temperatures, aluminium can enter the tip-to-sleeve gap and erode the tip.
