Plastics cap cooling machine speeds
output
Shorter cycle times for moulding plastics enclosures are putting pressure on cap cooling, for which a cap cooling machine is offered to solve the problem.
Reduced cycle time and increased productivity are the keys to increased profitability for companies manufacturing plastic caps and closures Sandretto UK supplier Greenbox has just introduced to the market a system called the Cap Cooler, which, according to Chris Whitlam, Sandretto UK National Sales manager, automation and ancillaries: "Has cap manufacturers across Europe queuing up for this product." Whitlam noted that: "With modern production, much larger number of closures are produced in a much shorter time and, as a result, problems related to the cooling of caps and closures after moulding have become much more dramatic"

Designed for all types of multi-component technology, a multi shot injection moulding machine uses a high-response hydraulic system.
Mould temperature controllers heat up quickly
Easy-to-maintain mould temperature controllers have fast and accurate heat-up time and can accurately maintain programmed temperatures.
"In fact, most closures typically emerge from the mould at a temperature of 90-95 deg C and then keep on releasing their heat once inside the collecting box." The solution to the problem is the Cap Cooler - a compact machine; easy to install and easy to operate.
It is formed of a rotating drilled drum and of a high flow and high pressure fan.
Two inverters control the drum rotation speed and the air flow, which must be adjusted in such a way that the closures slightly fluctuate inside the drum.
The rotation of the drum when combined with the fluctuation in the air grant a perfect uniform cooling of the closures.
The new Cap Cooler unit is especially designed for cooling the caps before they are discharged into the collecting box.
The caps are conveyed into the unit direct from the moulding machine: Once in the cap cooler they are suspended in air and can cool the cap down to within 3 deg C higher than the ambient temperature.
"One of the main benefits of the Cap Cooler," said Whitlam, "Is that not only are the caps cooled enough to be discharged directly into the box, the machine also produces a uniform cooling of the complete cap.
The Cap Cooler thus helps guarantee regular shrinkage and constant quality of the products.
Typical faults in cap production such as ovalization and deformation are therefore really reduced to a minimum." Many special versions of the Cap Cooler are available through Sandretto UK, including the following.
* For ambient temperature higher than 38 deg C.
* With absolute filters.
* For wide mouth closures.
And within a short space of time a new model of Cap Cooler - suitable for a production up to 90,000 closures/h will be introduced to the market.
