Q:The processing of plastic bottles
4, blow moldingBlow molding is also called hollow blow molding or hollow molding. Blow molding is a method of expanding a hot resin parison that is closed in the mold by means of the pressure of the compressed air to blow it into hollow products. Blow molding includes blow molding, film and blow molding, two methods. Blow molding can be used to produce film products, bottles, casks, pots, containers, and children's toys.5, calenderingCalendering is resin close by various additives expected (kneading and filtering) through the calender of two or more in favor of the opposing calender roll gap is processed into a film or sheet, then from the calender roller peeling off, and then by a molding method for cooling and shaping. Calendering is mainly used in the molding process of PVC resin. It can make films, sheets, plates, artificial leather, floor tiles and other products.6, foaming moldingFoaming materials (PVC, PE and PS etc.) incorporate proper foaming agents to produce microcellular structures. Almost all thermosetting and thermoplastic plastics can be made into styrofoam bottles. According to the pore structure is divided into open celled foams (feel most connected with each other and closed cell foam pores) (most pores are separated from each other), which is mainly composed of manufacturing methods (including chemical foaming, physical foaming and foaming machine) decision.
Q:What are the processes and machines used in the manufacture of plastic products?,
In recent years, the proportion of plastic products is increasing rapidly in many fields, such as household appliances, instruments and meters, building materials, automobile industry, daily hardware and so on. The requirement of high precision and high performance of plastic products increases with each passing day, which makes the precision forming technology progress constantly. Injection molding is one of the most important plastic forming methods, and many factors affect the precision injection molding. 1. in the early stage of the design of plastic products, injection molding materials should be selected according to their application environment. 2. precision molds, rational design of precision injection mold is the basis and necessary prerequisite for precision products. Precision molds are indispensable to produce precision products. The precision of the die is usually affected by the temperature control of the die, the precise manufacture of the die and the choice of the plastic shrinkage when the die is designed. 2.1 control of the mold temperature due to the effect of mold temperature on shrinkage molding, but also directly affects the mechanical properties of plastic products, can also cause various defects of product surface flooding, so must keep mold in the specified temperature range, but also to make the mold temperature changes over time. In the injection molding of general precision parts, the temperature of the die is controlled mainly to increase productivity. But the impact of temperature control of mold for injection molding is great, it affects parts of the shrinkage, shape, crystallization, internal stress, so the design of mold hot loop temperature distribution at the request reasonable precise control accuracy, the best use of mold temperature machine and cold water machine control.
Q:The next 5 to 10 years, small workshops waste plastics processing prospects for development?
Reference to prospective Industries Research InstituteAnalysis of production demand and investment forecast of modified plastics industry in China in 2015-2020The plastic machinery industry is the machinery manufacturing industry which provides important technical equipment for the plastic raw material industry and the plastic products processing industry. It is the floorboard of all kinds of machinery and equipment used in the plastics processing industry. After years of development, China's plastic machinery industry has initially formed a relatively centralized production cluster. Mainly distributed in Bohai, the Yangtze River Delta and the Pearl River Delta three regions.Since twenty-first Century, China's plastic machinery industry has been sustained and rapid development, is one of the fastest growing industries in the country, the main economic indicators among the forefront of the national machinery industry. With the development of chemical, mechanical, electronic and other related technologies, the status of plastics and plastic machinery in human economic life will be further improved. Plastic machinery enters our country to develop industry with advantages. China's plastic machinery industry has gone through years of entrepreneurship and development. Production enterprises are mainly located in the coastal areas of Southern China and East China, employing tens of thousands of technical level to improve rapidly, and achieved good sales performance in the international and domestic markets. The main products of the plastic machine industry overall upward market image. Industrial output value, sales and profits and taxes have been increasing at the same pace. Overall, plastic machinery has entered the ranks of China's dominant development industry.
Q:Build a small plastic bag processing workshop need what equipment and raw materials,
I just do this, the raw material is used PE, equipment, there are mainly blowing machine, punching machine, if you want to print, then also the printing press, there are other stirring what ah!
Q:What plastics products are used in daily plastic products?
What do you want to see the plastic products, such as water pipes, electric wire slot need is extruder; plastic film, plastic bags and other needs is the film blowing machine; plastic bottle blowing machine; like most plastic stool, pots, barrels, and other appliances to the injection molding machine shell.
Q:What machine is used for polishing plastic products?
Some plastic products come out very smooth, not in plastic polishing, polishing on the mold
Q:PC and PC alloy plastic surface effect which better, which good processing, and what are the other differences?
Compared to PC and PC plastic alloy surface, the effect of course is a good PC, PC water on the surface of the mirror effect, and the processing is good.
Q:The difference between plasticization and processability of plastics in extrusion process
I. Introduction of extruderIn the screw extruder is under the action of the molten plastic extrusion through fixed shape extrusion, water cooling after cutting in the traction machine under the same section is mainly used for a variety of products. A large number of continuous production, such as tube, rod, profile, also can be used for plastic modification and granulation. The basic mechanism of extrusion is very simple a screw in the cylinder to rotate and move forward the plastic. The screw is actually a ramp or slope that is wound around the center layer. The aim is to increase the pressure to overcome the greater resistance. Is an extruder, there are 3 kinds of resistance to overcome: solid particles (feed) on the cylinder wall friction and screw rotation before laps (feed) the mutual friction between them; melt in the cylinder wall adhesion; melt pushed forward when the resistance of the internal logistics.
Q:Plastic processing process
The purpose is to beautify the surface of plastic products, usually including: mechanical modification, namely with filing, grinding and polishing process, the removal of parts on edges, burrs, and fixed size; finishing, including coating surface parts, the use of a solvent to surface brightening, covered with patterned thin film surface; colour. Including painting, printing and printing; metal plating, including vacuum coating, electroplating and chemical plating method etc.. Among them, the hot stamping is heated, under pressure, the hot film on the color of aluminum foil (or other pattern film) transferred to the workpiece. Many household appliances and building products, daily necessities and so on use this method to obtain the metal luster or the wood grain and so on the pattern.
Q:What machines do we need to process Plastic semi-finished products?
Low profits, hard death, can not make a few money
