Heat Shield Coats type WSM (rigid) and WSMF (flexible)
General Information
Heat shield coats are primarily designed to reduce heat loss and, consequently, energy costs when heating machines, cylinders and tools. This results in electricity savings of between 20 and 50%. Furthermore, occupational safety is improved thanks to significantly lower surface temperatures in the areas where the heaters are operated and maintained. The heating-up time of the machine or tool is also reduced by up to approximately 50%.
Heat shield coats are always manufactured to fit the specific application. This is the only way to ensure that electrical connections, sensor inputs, drill holes and recesses are taken into account. It also ensures optimum efficiency and minimises any thermal bridges.
The payback period is usually less than a year. This is a significant factor given the continuing rise in electricity prices.
Typical applications in the plastics industry include:
Cylinders of injection moulding and blow moulding machines, flanges and moulds
Preheaters, feed hoppers and dryers
Connecting pipes between extruders and blow moulding heads
Moulds and moulded parts
Heat transfer oil systems
Insulation is not recommended for machines that generate high friction (e.g. worm gearboxes), produce significant internal heat or require cooling during operation. This can lead to heat build-up, overheating or the operating temperature being exceeded.
Type WSM
Type WSM heat shield coats consist of a sturdy metal shell with integrated insulation mats. Rigid metal shells also have an aesthetic appeal and give the machine an attractive appearance, which is why they are primarily used by machine manufacturers. Operating temperatures of 700 °C should not be exceeded.
Type WSMF
The flexible WSMF heat shield coats have been developed to reduce energy costs in injection moulding machines, heated moulds and, in some cases, extrusion lines. They are primarily used on existing machinery, as it is generally easier to install them in such systems. The operating temperatures of the WSMF should not exceed 500 °C. The energy consumption of the corresponding machine heating can be reduced by up to 35%. The surface temperature of the heat shield coats can be reduced to approx. 60 °C. Heat shield coats are manufactured from high-quality materials, which ensures a long service life.
Assembly Instructions
Type WSM
The solid thermal insulation jacket is secured to the cylinder using clamping bolts, clamping straps or clamping brackets. Installation can be carried out by your own specialist staff.
Type WSMF
The flexible thermal insulation jacket is secured using Velcro fasteners, hooks, eyelets, swivels or buckles. Installation can be carried out by your own specialist staff.
Care must be taken to ensure that the heaters on which the WSMF is mounted are started up in a cycled manner (start-up sequence).
