The supply water temperature is continuously rising and falling over a few moulding cycles.

Improved cooling will result in shorter moulding cycle times, increased productivity and improved part quality.

The sequence of events during the injection mould of a plastic part is called the injection moulding cycle.

Consequently, they have a superior injection moulded finish, and the moulding cycle produces consistent bottles time after time.

In order to maximise shrinkage during the moulding cycle the following rules should be followed: Increase mould temperature to force crystallisation almost to completion during moulding.

SPS also permits reduced wall thickness with longer flow lengths and consequently smaller runners/ reduced scrap, shorter moulding cycles and lower injection pressures.

Multiple-cavity Mould: A mould with two or more mould impressions; that is, a mould which produces more than one moulding per moulding cycle.

Two-shot or multi-shot moulds are designed to "overmould" within a single moulding cycle and must be processed on specialized injection moulding machines with two or more injection units.

It also slows down the moulding cycle times because it is necessary to wait for the moulding, or part of the mould in the hottest part of the mould to cool down to it's ejection temperature before the mould can be opened.

These include faster molding cycles, fewer production steps and a potential for reduction in energy usage.

In the majority of cases within tolerance parts can be coming off the press within 3-6 molding cycles.

Typical molding cycles are 60 minutes.

A mold-set cavity is typically filled in a few seconds but a typical full molding cycle is 20 to 45 seconds.

XL-IM is an injection molding technique that uses crosslinking polymerization during molding cycle.

Thermosetting resins such as Bakelite required heat and pressure during the molding cycle, but could be removed from the molding process without being cooled, again making the molding process faster.
