The plastic molding machine is otherwise known as the plastic forming machine. It was first developed by under the basis of rubber machinery and metal die-casting machine.The polymer molding machine and molding equipment since in the year 1870’s in an industry.Till 1930 it had a rapid development with the gradual commercialization with plastic molding equipment, injection molding and extrusion molding has became most common in the industrial processing method. one of the molding method is blow moulding, extrusion blow moulding.the blow molding is the third largest plastic molding method. Extrusion blow molding is the very fastest development of the plastic molding method.There are different types of plastic molding .They are plastic injection mouding,plastic blow moulding,plastic extrusion molding methods.The plastic extrusion is the high volume of manufacturing the raw plastic material is melted and formed into a continuous profile.extrusion material application are pipe/tubeing, weather stripping,fence,deck railing, window framing, thermoplastic sheet, and wire insulation etc.The plastic molding machine is a device which melts the plastic and materials made from the other polymer and then it is injected into moulds.It is most offen used for the recycle plastic,uaually which supports the primary device which produce plastic material at the first time of the plastic object.
It plastic molding method has a different variety of method, but they all include an injection and clamping unit.Injection unit is mainly responsible for the melting the plastic and injected and forced to enter into the mold by using ram or screw, eventually the screw method is very more common. The hopper dryer is characterized by the temperature controlling system generally used for the purpose of drying efficiency. In the meanwhile there are many different types of methods they are hot-air dryer models and desiccant dehumidifying model all of liable and confident models for the both local and foreign plastic materials.
There may be many merit such as simplified operation, saving on manpower, effect on ultra dying and decreased cycle time. The dried air is thoroughly dehumidifying the plastic granules to extensively and widely improve the efficiency of the engineering resins. The hopper dryer is the most essential way of drying plastic materials. Directly drying of the plastic material at the throat of the machine which eliminates the contamination and re-absorption of the moisture content of the plastic material which transporting from the central drying position to the machine hopper. All model include rapid heating for about 24 hour timer,7 hour timer and 99 hour timer. The some basic features of the hopper are ,The best performance of hot air distributing device to dry plastic material at most common and at even temperature. Specially designed curved heating pipe to avoid the plastic resin, which cause resin burning. Smooth and softer pipe to avoid the plastic dust. Inner parts of the hopper are made of stainless steel. It also has the eclectic temperature controller. It is provided with the P.I.D temperature controller ant the LED display.
