Purging compound, specifically commercial purging compound, is a product formulated specifically to clean thermoplastics molding machines and extruders. Purging compound is also used for color and material changes, removal of color and carbon deposits as well as cleaning hot runner mold.

A mould in which the runners are kept at a temperature that is higher than the solidification temperature of the material.

CONT

Hot runner molds. Thermoplastic runners are reground and reused. A logical extension of the three-plate mold overcomes this and is called a hot runner mold. This mold has a hot runner plate, which is a block of steel heated with electric cartridges, thermostatically controlled. This keeps the plastic fluid. The material is received from the injection cylinder and is forced through the hot runner blocks into the cavities. It is a more difficult mold to build and operate than a three-plate mold, but produces parts less expensively on longer-running jobs.

CONT

Parts made from partially crystalline engineering polymers should preferably not be made by hot runner injection moulding if a perfect surface finish is essential. It is advisable to make use of a subsidiary runner, which thermally isolates the nozzle from the moulded part, thereby reducing the risk of surface defects.

OBS

Runners can be classified into two types, namely the cold runner and the hot runner. The mold temperature for the cold runner is similar to the mold temperature for the cavity. The material in the cold runner will eventually solidify, and be ejected with each cycle. The hot runner maintains the polymer at a melt temperature, either by insulation or by heating. This keeps the material fluid. Hot runners are not ejected with each cycle.

CONT

Insulated runner molds. A combination between a hot runner mold and a three-plate mold is called an insulated runner mold. The gating system is very similar to that of a three-plate mold except that the runners are very thick, at least 1 3/4in.(45mm) in diameter. There is no runner plate, and the backup plate and A plate are held together by latches. After the material is injected, the outside of the runner freezes but insulates the center, permitting the core to remain fluid at molding temperatures and act as a hot runner.
