Supacool

A significant step change in production capabilities for rotational moulding.

Supacool is an internal water cooling unit that has been designed to bolt onto the outside of vent holes. It connects to a compressed air line which then activates an injector that delivers up to three litres of fine water mist inside the part during the cooling process. This contacts the plastic directly causing rapid and efficient cooling from what has traditionally been the most inaccessible part of the rotational moulding cycle.

As the misted water vapourises to steam, large amounts of heat energy are absorbed within the mould dramatically reducing the temperature and the subsequent cooling times usually required. Excess steam produced is then vented back through the unit. This incredibly valuable accessory reduces warping and cycle times significantly.

Best of all, Supacool works with all your existing moulds bolting easily onto the outside of the mould over an existing vent hole.

 

Why supacool?

  • Cools your parts both internally and externally

  • Faster cooling times increase production

  • Higher quality parts and uniformity

  • Can be used with existing systems

  • Reduces warping and cycle times

  • Produces better quality parts more quickly

  • Improves surface quality and finish

Don't wait any longer take control of your cooling process and reap the benefits of Supacool immediately. You won't just save time, you'll make better quality parts and serve your customers better.

Fitting Requirements

The Supacool unit is easily bolted to the outside of the mould and fits inside a tube 280mm (11”) in diameter and 280mm (11”) long.

Depending on the size and shape of the mould, a solid vent tube extension 44.5mm (1 3/4”) may also be required. Otherwise a standard 25mm (1”) Smartvent is sufficient. Please note if Supacool is to be used against the line of draw a quick release procedure should be incorporated to facilitate mould servicing. Please contact us for further details.

Please be sure to read the manual prior to using this product.

Benefits

  • Cooling with water is faster - the cooling cycle is usually around 50% of the total cycle time. The use of internal water cooling typically allows for the reduction of the cooling cycle by over 50%.

 

FAQ

1. How much water will Supacool deliver to the part?

It depends on how much water Supacool is 'pre-charged' with. Supacool has a maximum capacity of 3 litres. The pre charge will depend on the size of the mould . The larger the mould, the greater the volume of water, the smaller the mould, the smaller the volume. If the volume is too large for the size of the mould, the water droplets may condense.

2. Will Supacool work with our existing setup or will I need to modify the mould?

The base plate that Supacool is mounted onto needs to be bolted onto the outside of the mould in which it will be used – usually over an existing vent hole (depending on the location of that hole). If the same unit is to be used on multiple moulds, additional mounting plates need to be purchased to enable it to be swapped between them.

3. Where can I buy Supacool from?

Supacool can be purchased from any one of our distributors?

4. What impact does water have inside of the plastic part?

Explanation of what happens when water is dripped onto hot plastic rather than steam.....

a) Liquid water dropped onto molten plastic will leave a small crater defect in the plastic. A drop of water hitting molten (hot) plastic will vapourise and the expansion involved in this process, causes the crater.

b) Therefore, water droplets of a larger size are undesirable because of this effect. If any of the injector junctions are leaking or a nozzles ceases misting effectively (generally through a partial blockage – often scale build up from water impurities), larger sized droplets may contact the plastic causing a stippled look.

c) This will be more of an issue on smaller parts and is generally not a problem if the directions are followed. In bigger parts, larger water droplets are likely to still be vapourised before they contact the molten plastic because of the increased time and distance to contact

5. What sort of moulds would Supacool be most useful in?

Supacool will be useful in moulds where you want to reduce the cooling time significantly. It will be more useful in larger, thicker walled moulds where the cooling cycle time is prolonged. For smaller, thinner or double walled moulds, especially with tight 'kiss-offs', internal air cooling via Technovent would be a better choice.
