I would like to produce some plastic products, and ask for help. How much is the equipment?
- It's good for you to understand these words when I don't understand them. Starting with raw materials, recycled plastics and so on.s
What are the processes and machines used in the manufacture of plastic products?,
- Processing methods are: injection molding, extrusion, blow molding, blister and so on. Injection molding can be used to produce more complex shapes, such as TV housings. It is the plastic particles in the pre heating tube, and then through the screw under pressure, the melting of raw materials into the mold, cooling molding, the product has been made. Is prepared by continuous extrusion screw drive, which in the feed pipe (commonly known as the barrel) heating plasticization, and then squeeze the stereotypes in the mold, the desired shape, such as plastic buckle, pipes etc.. Blow molding and extrusion are somewhat similar, except that they are placed in compressed air to obtain shapes, such as plastic films, plastic bottles, etc.. Blister is relatively simple, it first made of plastic sheets, baking oven, and then placed in the mold, through the negative pressure to the sheet and mold close to the shape. The price of the equipment varies greatly according to the model and specifications, so it can be checked directly to the manufacturer.s
I plant mainly produces plastic products,
- Can be deducted from the value-added tax invoices on value-added tax deductible, in addition to the purchase of equipment costs, if there are qualified transport documents, you can also by freight * 7% deduction of input taxs
What mechanical products do you use to make this plastic product?! The more detailed, the better!
- I'm not sure about the mold design. You can find a device and ask for advice. Generally, they will be responsible for design and trainings
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.s
I want to open a small factory dealing with plastic bags.
- The first said equipment 1 blowing machine 2 printing machine 3 bag making machine 4 mill material if want to make your own words also need about 27000 granulating machine, film blowing machine, printing machine if printing a color around 10 thousand,s
I would like to do plastic crushing processing,
- Different kinds of waste plastics have different characteristics. As far as impurity content is concerned, waste materials in the middle and outer corners of the factory produce impuritiesThe content of less than 0.1%, piled up scrap for a period of time and other products used for% impurity content 0.1 ~0.5%, mixed with aluminum, cloth and paper composite plastic waste impurities are often more than 10%. For used waste plastics,According to different use conditions, will include ultraviolet radiation, heat, oxygen aging effect, pollutants.Ring. For different shapes of waste plastics, the volume density of materials after crushing is very different, film, sheet, flatThe volume density of the crushing material is smaller, which is a problem that must be considered in the process of waste plastics recycling and granulation.Two. Pretreatment of waste plasticsFrom discarded packages, such as bags, shopping bags, bottles, cans, boxes and waste agricultural film waste plastics, inPretreatment prior to granulation. The pretreatment process mainly includes classification, cleaning, crushing and drying.Classification work is the classification of miscellaneous waste plastics products according to the type of raw materials and product shapes classification. By raw materialsClass sorting requires operators to have a good knowledge of identifying plastic varieties, and the purpose of sorting is to avoid different speciesThe resulting polymers are incompatible with recycled materials and have poor performance. They are classified according to the shape of the product to facilitate the use of waste plasticsThe crushing process can be carried out smoothly, because the film, flat and fabric used in crushing equipment with some thick and hard wareThe crushing equipment often can not replace each other.s
Where plastic processing plant is more, better?
- What other plastic pot instead of well, to know a few thousands of large plastic mold, many tens of thousands of large; if you need a lot of, clear their own requirements, I think there are many manufacturers are willing to do, your preferred OK.s
