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, they can win high praise from the public. More customers invest in the plastic products industry. As a small editor of the hollow blow molding machine company, we must popularize the production process of the plastic blow molding machine for you who do not know the plastic industry.
This article mainly asks you to introduce the content of plastic products production equipment introduction, production and processing process and other aspects, a comprehensive introduction of plastic knowledge to help you quickly understand the production process.
I Plastic processing technology introduction
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.
The production of plastic processing products are common equipment blowing machine, injection molding machine, extruder three kinds, the production process is roughly the same, the different is the reproduction process of the material is different, this article Xiaobian 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, water chiller.
Plastic products are used in the production of plastic synthetic polymer materials are plastic, polypropylene, polyvinyl chloride, polystyrene, polymethyl methacrylate, polyformaldehyde, polycarbonate, are now common life indispensable three synthetic materials. Say ACCURATELY, PLASTIC IS WITH NATURAL OR SYNTHETIC RESIN IS MAIN COMPONENT, ADD ALL SORTS OF ADDITIVE, CAN MODEL MAKE CERTAIN SHAPE BELOW CERTAIN TEMPERATURE AND PRESSURE AND SO ON CONDITION, THE MATERIAL THAT MAINTAINS SHAPE INVARIABLE BELOW NORMAL TEMPERATURE.
II Plastic products production process
The processing process can be divided into 5 plates, batching, molding, mechanical processing, joint, modification, let's introduce one by one.
1, plastic products processing raw materials, in addition to the polymer will also add a variety of stabilizer, plasticizer, colorant, lubricant, enhancer and filler plastic additives to improve the molding process and product performance or reduce the cost of products. Additive and polymer by mixing, can be evenly dispersed into powder, also known as dry mixture. Sometimes the powder also needs to be processed into granular material by plastic refining. This kind of powder and granule are collectively referred to as compound or mold plastics.
2, molding processing, processing link is an important part of plastic manufacturing equipment, all kinds of powder, granule, solution or dispersion of plastic, made, molding processing method has a lot of, choose which process depends on plastic products is thermoplastic or thermosetting, initial form and product appearance and size, Thermoplastic processing common methods are extrusion, injection molding, calendering, blow molding and thermoforming and other processing methods, heating solid plastic generally will have molding, transfer molding, but also injection molding. If it is liquid and polymer as raw materials with extrusion and injection molding more.
3, joint, plastic parts joint method welding and bonding, welding using hot air welding, high frequency welding, friction welding, induction welding, ultrasonic welding method to achieve joint products. The use of flux, resin solution, hot melt adhesive as adhesive bonding products.
4, modification, bonding, welding and mechanical connection methods, so that made of plastic parts assembled into a complete product operation. For example, plastic profiles are assembled into plastic window frames and plastic doors after sawing, welding, drilling and other steps.
The above is all the content about the detailed processing process of plastic products. I hope the article will be helpful to you.
