Application :                                              
Water chillers in plastic            
and plastic industries: according to different uses of equipment, they are divided into injection chillers,extrusion chillers, suction chillers, bottle-blowing chillers, compression chillers, film-blowing chillers, film-spraying chillers, calendering film chillers, casting film chillers, boiling water chillers, PU shoe chillers, leather press. Flower chiller, etc.
The application of water chiller in the cooling of plastic processing machine forming die can greatly improve the surface smoothness of plastic products, reduce the surface markings and internal stress of plastic products, make the products not shrink and deform, facilitate the demoulding of plastic products, accelerate the product finalization, thus greatly improving the product quality and production efficiency.
Plastic particles are melted by heating and injected into the mould. After solidification, the plastic parts are ejected from the mould. In the continuous production process, the mould needs to be cooled to shorten the plastic solidification time, improve the dimensional accuracy of the workpiece, the forming quality and the surface quality.
If plastic containers, bottles and packaging films are not cooled and shaped in time during production, the containers produced will not be full, uneven wall thickness, unclear color or even can not be shaped, resulting in lower product quality. The use of water chillers can not only greatly improve product quality but also improve production efficiency.
Water-cooled standard chiller
1. International well-known compressors: the use of international well-known brand fully enclosed high-efficiency flexible scroll compressor, simple compression components without wear, small moment change, high balance, energy-saving, efficient, stable and reliable, easy to operate and easy to achieve automation control;
2. Shell-and-tube condenser: using high-efficiency external threaded copper tubes, using the latest CAD/CAM design and processing technology, with CNC processing center production, corresponding to heat dissipation, water flow rate, scaling coefficient, calculating the effective heat transfer area, leaving 5-10% surplus; both end caps are easy to disassemble, easy to maintain;
3. Evaporator: Using steel-plastic composite shell-and-coil heat exchanger, heat exchanger tube is a high-efficiency internal threaded tube, which is a high-tech small channel product developed from international heat transfer enhancement technology. The special pipe arrangement makes the heat transfer coefficient reach the leading level in the field of heat exchanger at present, and can maximize the operation efficiency of the unit. The shell is steel-plastic composite, and the water surface is sealed engineering plastic. It has strong corrosion resistance and long service life. After many freezing tests, no internal and external cracks were found in the special designed structure, and the frost resistance was excellent. The shell is removable and easy to maintain and clean.
4. Control system: Industrial-level centralized control system, all-Chinese operation interface, menu prompt easy to operate, can view the operation status of the unit at any time, adjust the working mode, accurately control the matching of refrigeration capacity and cooling load, ensure the unit to operate with the best efficiency and reduce operating costs. Internal integration of water flow, low temperature, high and low pressure, anti-freezing, reverse phase, delay start, overload, over-temperature, oil pressure difference and other security protection functions. Accurate control can control the temperature in the range of (+1). It is easy to operate, safe and reliable.
5. Electrostatic spraying shell, fully enclosed box structure, beautiful and generous shape.
