Diecasting Plunger Lubricant.J & S Chemical's Shotbeads are a blend of waxes and additives that are attracted to heat and rapidly spread on the chamber surface. They lay down a friction-reducing film that puts extreme pressure additives where they are needed. This film gives the user maximum lubrication lubrication, introduction of a substance between the contact surfaces of moving parts to reduce friction and to dissipate heat. A lubricant may be oil, grease, graphite, or any substance—gas, liquid, semisolid, or solid—that permits free action of while reducing soldering. An inert additive provides graphite-like barrier protection against washout washout to disperse or empty by flooding with water or other solvent. medullary solute washout a syndrome in which the relative hyperosmolarity of the renal medulla is reduced due to an excessive loss of sodium and chloride from and thermal shock Thermal shock in mechanical models Thermal shock is the name given to cracking as a result of rapid temperature change. Glass and ceramic objects are particularly vulnerable to this form of failure, due to their low toughness, low thermal conductivity, and high . When the metal is poured, the lubricating film is chased to the front of the sleeve. When the shotarm begins to move, the film is pushed into the cavity area, providing extra lubricity lu·bric·i·ty n. The quality or condition of being lubricious.

creating maximum metal flow. The shot tip is completely coated on the
face and sides with a protective lubricating film. The amount of
lubricant used depends on the size of the tip and the casting weight.
They are used on machines from 400-3500 tons and are available in 50-lb
boxes and 250-lb drums.
