These foaming plants are designed for two different types of cabinet:
- Vertical refrigerators or vertical display cabinets for shops, supermarkets, merchandisers with single or multiple doors, also called reach-in coolers and Glass Door Freezers.
- Horizontal display cabinets for shops, supermarkets, icecream parlours, medical and research laboratories.
The production needs for this application is not very high in terms of capacity by with a lot of different model configuration. For this reason, the equipment/plants are based on stationary jigs/fixtures which can be foreseen for the “door-up” or “door-down”injection.
- Stationary Jigs – Single Plug
These are fixtures with a single plug which can be foreseen for “door-down” or “door-up” injection. For a model change, it is necessary to replace or adjust the plug according to the design of the internal liner of the new refrigerator model to be foamed and it is also necessary to adjust the supporting side walls and top-bottom supporting walls according to the external dimensions of the new refrigerator cabinet to be foamed. - Stationary Jigs – Multiple Plug
This equipment is suitable for the injection of the cabinets in the “door up” position. It has basically the same technical features of the “single plug fixture” but in addition it is equipped with the “multiple plug system” which can have 2-3 or 4 plugs fixed to an upper rotating structure called Rotoplug®. - Shuttling-Plug Fixtures
This type of fixture is used for injection of cabinets used for large vertical refrigerators or horizontal display cabinets which are very difficult to transport/handle in horizontal position on conveyors.
