Plastic Industry
Why plastic process chiller?
Process cooling in plastic processing is necessary as considerable amounts of heat have to be removed from the material, mold or machine, such as plastic injection, plastic extruding (sheet extrusion or profile extrusion), bottle blowing and film blowing etc.
Before shaping, thermoplastic materials such as polypropylene, nylon and PET etc.
Thermoplastic must be heated to their molten temperature. When molten, they can then be manipulated (injection molded, extruded etc.) to a new shape. Finally they must be solidified them via cooling.
what plastic process chiller do?
· cool the hot plastic that is injected, blown, extruded or stamped to maximize productivity and improve the quality.
· cool down the plastic process equipment that is used to produce plastic products, such as hydraulics of the molding machine, gear box and barrel of the extrusion machine, to save energy and extend lifetime of the machine.
We are professional to design any independent water chiller as per you cooling requirement, for any types of plastic pressing machine, such as
plastic injection machine, sheet extrusion machine, profile extrusion machine, bottle blowing machine, film flowing machine, etc.
Moulding Process
Water chillers are used for cooling mould to improve the smooth finish of plastic products and reduce the internal stress. It is easy to demould plastic products and the output has been raised. Water chillers are also used for cooling all kinds of lubricating oil and hydraulic transmission oil to control the oil temperature accurately and improve the processing accuracy.
INJECTION MOLDING
The injection molding of thermoplastic materials is the most widely used technology in plastics processing.
Production includes pieces of different shape and size with weight ranging from a few grams to several kilograms. The cooling of both the oil and the moulds circuit is an important and essential step into the process. Dry Chill offers several solutions, many of them aimed at reducing energy consumption, depending on the application and the quantity of material to be processed.
FAST MOULDING
The production of molded parts such as medical equipment, food products and plastic bottle caps drew the interest of many IMP manufacturers.
The products must have characteristics of absolute quality in terms of repeatability and aesthetic aspects as the dimensional tolerances accepted by these productions are really tight. In the long run, the manufacture of product with poor quality content would be in fact an economic loss, since some products offer a limited margin that can be justified only with large production volumes. In the so-called fast molding it is then preferred the use of 48/64 multi-cavity molds, able to ensure, thanks to the fast molding cycles, a high production rate.
