Sheet machine and the characteristics of thermoplastics

Sheet machine and molding machine is main production equipment in the production of plastic products, which generally in thermoplastic plastics processing machinery production, so why will be the plastic cup machine, molding machine main material, here is to introduce the characteristics of the plastic. Thermoplastic qualitative light, density of 0. 83g/cm3~2. 20g/cm3； Good electrical insulation, non-conductive and arc resistance, etc. Good chemical stability, general acid, alkali, salt and organic solvents, have good wear resistance and lubricity, higher than strength. Glass fiber and carbon fiber reinforced plastic, in particular, can achieve more than than the strength of steel. Good pigmentation, spraying, hot pressing method such as printing and printing can be used for a variety of color appearance of plastic parts, and this method of thermoplastic plastics can be used in a variety of molding processing, high production efficiency, it is lunch box machine, plastic machinery to the cause of the material for raw materials. Main drawback is the difference in heat resistance, thermal expansion coefficient is big, poor dimensional stability. Under the load, aging, etc. , but you can improve and enhance through various methods. Because of the source of the synthetic thermoplastic is widespread, mature technology, so the plastic production in the world today, three-quarters of thermoplastic plastics, but also will continue to grow.
