Processing method of PP sheet production line equipment

PP (polypropylene) hot forming sheet is a kind of plastic sheet widely used in positive pressure hot forming in China. Even in all the thermoforming plastic plate family, but also early latecomer, and PVC, PS raw materials use almost equal. At this stage of the market can often see the "disposable" plastic crystal jelly cups, drinking water with sanitary cups, soy milk cups, soy product boxes and almost 100% PP plastic sheet hot forming production and processing; In China's "disposable" plastic yogurt cup sales market, PP raw materials also occupy half of the country; Daily life on the "disposable" plastic lunch boxes, take-out boxes, cold food cups and other goods with PP plastic sheet thermal forming production and processing of more can not be counted. Plastic packaging products with PP plastic sheet thermal forming production and processing products in the pharmaceutical industry, light industry, small toys, food, vacation tourism and other aspects of the use is really commonplace. The key reason depends on the PP raw material is one of the lighter plastic types, the relative density is only 0.89 -- 0.91g/cm³, low cost of raw materials; Second is the relative price of raw materials cost-effective, sales market available, very easy to buy; In addition, the production process is easy to grasp, simple seasoning, very easy production and processing; It is important to produce equipment that is cost-effective and very easy to cross horses.

With the old and new plastic sheet production line in China, the introduction of foreign enterprises and large equipment, and the use of new raw material procurement, hot forming field shows a trend of continuous development. Hot forming sheet production and processing technology is also accompanied by differences in equipment, raw materials and main uses. The increasingly perfect production and processing technology of plastic sheet slowly got rid of the standard basic theory of the old era. Today, even in the same plastic plate production line, you can also use different processing technology to produce different main uses, different specifications and models, different materials of the standard plastic plate; The same specifications and models of the main use of plastic sheet can also be used in different machines and equipment, processing technology production and processing out. "No way" brings great convenience to manufacturing.
