Plastic products are widely used in daily life. In agriculture, packaging, transportation, electrical, food, daily necessities and other industries, due to their excellent cost performance advantages and quality parameters in all industries, they can win public praise. More customers are invested in the plastic products industry. As a small series of hollow blow molding machine company must be for you do not understand the plastic industry popular science, plastic blow molding machine production process.
Here mainly asks you to introduce the content of plastic products production equipment, production and processing procedures, comprehensive introduction of plastic knowledge for you to help you quickly understand the production process.
I. Introduction of plastic processing technology
Plastic production technology, has been become the main purpose of the plastic molding process is made into the synthetic resin industry all kinds of plastic products, is a common in the plastic processing industry production process, machining process generally includes plastic ingredients, molding, mechanical processing, joint, modification, such as process, mechanical processing, joint, plastic modification process in the semi-solid state, also known as secondary processing.
Production of plastic processing products are common equipment blow molding machine, injection molding machine, extruder three, the production process is roughly the same, the difference is the process of reproduction in the discharge way is different, this article to blow molding machine as an example to introduce the production process. Blow molding machine is also equipped with a large number of auxiliary machines, good drying hopper, grinder, mixer, air compressor, chiller.
Plastic products are produced using plastic synthetic polymer materials polyethylene, polypropylene, polyvinyl chloride, polystyrene, poly methyl methacrylate, polyformaldehyde, polycarbonate, are now often indispensable to life of the three major synthetic materials. To be precise, plastic is natural or synthetic resin as the main component, add a variety of additives, under certain conditions such as temperature and pressure can be molded into a certain shape, at room temperature to maintain the same shape of the material.
II. Plastic products production process
The processing process can be divided into five parts, batching, forming, mechanical processing, joint, modification, we introduce one by one.
1, plastic products processing raw materials, in addition to the polymer will add a variety of stabilizers, plasticizers, colorants, lubricants, enhancers and fillers and other plastic additives to improve the performance of molding process and products or reduce the cost of products. After mixing with the polymer, the additive can be evenly dispersed into powder, also known as dry mixture. Sometimes the powder also needs to be processed by plasticizing granular materials. The powder and granule are collectively known as compound materials or molding plastics.
2, molding processing, processing is an important link of plastic manufacturing equipment, will be all kinds of powder, granule, solution or dispersed plastic, made, molding processing methods are very kind, choose which process depends on plastic products are thermoplastic or thermosetting, initial shape and product shape and size, Processing thermoplastic common methods have extrusion, injection molding, calendering, blow molding and hot molding and other processing methods, heating solid plastic generally will have molding, transfer molding, also can use injection molding. If it is liquid and polymer as raw materials with extrusion and injection molding more.
3, joint, plastic parts joint method has welding and bonding, welding using hot air welding, high frequency welding, friction welding, induction welding, ultrasonic welding method to joint products. Bonding more use of flux, resin solution, hot melt adhesive as adhesive bonding products.
4, modification, with bonding, welding and mechanical connection methods, so that the plastic parts made into complete products. For example: plastic profiles, through sawing, welding, drilling and other steps assembled into plastic window frames and plastic doors.
The above is about plastic products detailed processing process introduction of the whole content, I hope the small series of articles to help you.
