It is reported that in the alloy die-casting injection mold production needs to use a temperature control equipment, it is die-casting mold temperature machine. Die casting mold temperature is a die-casting mold temperature machine, the mold temperature will lead to unreasonable size instability in the production process, the top castings deformation, resulting in thermal stress, sticky mold, surface depression, shrinkage and thermal bubble defects . Die casting mold size is much larger than the injection mold, the need for heating and cooling load; In the production of die-casting, the alloy solution temperature up to five or six hundred degrees, while the mold temperature to be stabilized at 100 degrees to 300 degrees, while die-casting mold Of the hot runner is relatively long, the use of high temperature, so need to die-casting mold temperature control, but most of the oil temperature machine, high temperature, high pressure hot oil circulating pump heat transfer oil in the die-casting mold and mold temperature cycle.
Die casting mold temperature machine in the mechanical design is mainly to achieve the work of die-casting metal products, less heat loss of functional effects. Die-casting mold heat exchangers unique design, heating and cooling unit is the form of components into the tube, and special ceramic fiber for leather protection, the advantage of flexible installation. The HTF flows at a rate of 3 meters per second on the barrel flute and the heater is in the center of the tube, so that the heating effect is uniform and does not overheat the local temperature due to other hot-dip or side-thermal designs. mold injection

Heat transfer oil to the injection mold to control the mold temperature. If the temperature is lower than the set value, the control system turns on the heating element to heat the HTF; if the temperature is higher than the set value, the control system turns on the cooling element, and the cooling heat conduction oil. The equipment adopts the automatic control mode, which can play a very good temperature control effect, improve the inherent and surface quality of the alloy die-casting parts and prolong the service life of the die.
In addition to injection molding, extrusion, blow molding machines and other hosts, the plastics processing industry is also extensive use of various auxiliary equipment. For the modern plastics processing industry, the performance of auxiliary machinery also has a significant impact on product quality and the productivity of the business. A wide range of plastic auxiliary machines, are widely used in various fields of plastic processing industry, plastic auxiliary machines are essential equipment, and sometimes an integral part of the entire production line. One of the mold temperature machine is a very important part of plastic auxiliary.
Die-casting machine in the die-casting industry there is also a lot of room for use, especially in magnesium alloy, aluminum alloy manufacturing, uneven or improper injection mold temperature will lead to instability casting size, the top of the casting deformation in the production process, Produce thermal stress, sticky mold, surface depression, shrinkage and hot bubble and other defects. The production cycle also has an impact, such as filling time, cooling time and spray time are unstable variables. Die life will also be affected by overheating and overheating of the impact of expensive steel hot cracking, to accelerate its aging.
Currently on the market there are two kinds of mold temperature machine: water mold temperature machine, oil mold temperature machine is different, its working principle is the same, just use the media according to the actual have different choices Ord mechanical production mold temperature machine excellent quality , Good reputation, is widely used in plastic molding, light guide, pressure casting, rubber tire, roller, chemical industry, reactor, adhesive, mixer and all walks of life.
In the modern factories, the business strategy of saving manpower, improving quality and reducing costs in response to market competition is urgent. With the use of mold temperature machines, mold preheating time can be reduced, surface quality of finished products can be improved, and production can be fully automated. Improve the life of the mold is necessary to improve productivity.
In the use of die-casting industry also has a lot of space, especially in the magnesium alloy, aluminum alloy does not mean that or improper injection mold temperature can lead to instability in the size of the casting, injection molding in the production process deformation, thermal stress, sticky Hysteresis mode, surface depression, shrinkage and hot bubbles and other defects. With the production cycle and the impact, such as filling time, cooling time and spray time instability change. In addition, the service life of the injection mold can also be affected by the overheating and overheating of expensive steel hot cracks, accelerated aging.

Engineering plastics and specialty plastics for automotive applications Increasingly large parts directly lead to the Plastic Mould must be large-scale
