The extrusion moulding temperature of Air Cooler Mould(FURNITUREMOULD) parts is the most critical function in the injection moulding process-no matter what kind of plastic is blown, it is important to ensure that moisture is generated on the surface foundation of the air cooler mould. A hot air cooler mould surface keeps the plastic surface liquid for a long time to generate water pressure in the mould cavity. If the cavity is paved and soft plastic can be pressed on the alloy by the cavity water pressure before the frozen and clean skin is hardened, the copy of the surface layer of the cavity is high. At the same time, if the plastic entering the cavity under the bottom pressure is stopped, no matter how short the time is, the slight contact between the plastic and the alloy will cause stains, which are occasionally called gate stains. For this kind of plastic and plastic parts, there is a limit of the ambient temperature of the air cooler mould, beyond which this or a large number of negative effects (e.g. parts can overflow burrs) will occur. Die parts, extrusion die parts higher extrusion temperature means less travelling pressure. On many plastic machines, this ecology means passing through the gate and cavity rapidly. Since the common blow moulding travelling pressure regulating valve may not correct this change, the rapid filling will cause higher reasonable water pressure in the gate and cavity. Will cause flash burr. Because hotter modelling does not necessarily freeze and clean the plastic that enters the overflow edge area before high pressure is generated, the melt can overflow burrs around the injection rod and overflow into the gap of the dividing line. This shows that there must be excellent injection speed control, and some intelligent swimming control programmer can indeed ensure that in fact. In general, the increase of the mould temperature of the air cooler will reduce the cold suspect layer of the plastic in the mould cavity, making the melted material easier to move around in the mould cavity, thus obtaining larger net weight of parts and stronger technological performance. The increase in the temperature of the air cooler mould will also increase the strength of the supporting force of the parts.
