Water-Passage Descaler
Routine Use of Lime Buster Keeps Molds Running at Peak Performance!
Lime Buster™, the original water passage descaler, dissolves and
flushes lime, scale and rust from molds, heat exchangers and water
lines to restore peak cooling efficiency and slash maintenance time.
Safe for All Mold Types!
The Problem
Water circulators provide mold temperature control, but water can leave deposits that insulate the mold from the circulating water; as little as 1∕64″ can reduce heat transfer 40%. Full temperature change takes longer. Cycle times and electricity use go up as part quality goes down.
The Solution
The IMS Lime Buster circulates a mild acid through your mold water passages, dissolving mineral deposits and flushing them away. Circulating water can then have direct contact with the metal in the mold, restoring heat transfer. You’ll see shorter cycles and better parts.

Minerals in passages block heat transfer causing loss in temperature control & cycle time.

Why Descale?
Descaling mold water passages (channels within the mold through which coolant flows to control the temperature during the molding process) is an essential aspect of mold maintenance in injection molding.
