The heating and cooling device of plastic formwork productio

The plastic template production line is widely used and is generally welcomed in current use. In addition, heating and cooling are necessary for plastic extrusion. Do you know this heating and cooling device? The following article details the heating and cooling devices for the device. Let's study together.

(1) the current plastic sheet equipment usually adopts electric heating, which is divided into resistance heating and induction heating. The heating plate is installed in various parts of the body, the neck and the head. The heating unit heats the plastic inside the cylinder from the outside to achieve the required temperature for process operation.

(2) the setting of the cooling device ensures that the plastics are within the temperature range required by the process. Specifically, it is to eliminate the excess heat generated by the shear friction caused by the rotation of the screw, so as to avoid the plastic decomposition, burning or solidification difficulties caused by excessive temperature. Barrel cooling can be divided into water cooling and air cooling. a

       Generally speaking, air cooling is more suitable for small and medium-sized plastic sheet equipment, while water cooling or a combination of the two is more suitable for large plastic sheet equipment. Screw cooling mainly USES central water cooling, the purpose is to improve the material solid delivery speed, stable glue output, improve product quality. However, the cooling at the hopper is intended to prevent

       Strengthen the conveying function of solid materials, prevent the plastic particles from sticking and blocking the material ports due to the rising temperature, and ensure the normal operation of the transmission parts.

       Heating and cooling devices for plastic sheet equipment are important equipment for good operation. This article explains the installation reason of the equipment and the working principle of the equipment in detail. We  can have a general understanding of it, which can be referred to in future practical operations.
