FAQ
- 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.
- this month bought a 180 thousand of the equipment and issued a value-added tax invoices, this sum of money can be deducted? How much deduction?Previously fixed assets are not deductible? Is this a policy that has just been changed this year? What's the tax rate? Thank you！
- 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 tax
- Which kind of engineering plastics can be machined on machine tools?
- General raw materials market is available, you can also contact the internet.
- My home is the county seat, want to open a waste plastic recycling, and then processed into plastic particles factory, do not know how the market? If there is cooperation between manufacturers, the best production, processing can also be.
- There are many kinds of plastics, even if they are recycled and processed into granules. Different materials also have different machines. High temperature materials can not be used by ordinary machines, and technology is needed. Otherwise, they may become garbage.
- Environmental impact of foam plastics reprocessing
- When people are exposed to vinyl chloride, there will be a wrist, finger edema, skin sclerosis and other symptoms may also occur splenomegaly and liver injury disease. In our country, the ultra-thin plastic bags we use almost all come from the reuse of waste plastics. They are produced by small businesses or family workshops. The raw materials used in these factories are waste plastic barrels, pots, disposable syringes, etc.. Production, first used machinery to crush the raw material of plastic particles, plastic particles and then placed in a pool cleaning (called disinfection), check out the sun, and then the mechanical pressure it film, made of a variety of plastic bags. Every meal, many people use plastic bags of food, they do not know this behavior, not only harmful to the environment, but also harm their own bodies.Make the soil environment worse, and seriously affect the growth of crops. The degradation time of plastic products used in China usually takes at least 200 years. Waste plastic, plastic bags in the field long residue in Tanaka, will affect the absorption of water and nutrient of crops, inhibit the growth and development of crops, resulting in crop production. If the animal eats plastic film, it can cause the digestive tract disease and even death of the livestock.
- tooling mold design, processing, whether the need for quality certification system?
- Management system certification is basically looking at the enterprise's own needs, nor is it mandatory, but if you are here, if useful in the car, you have to do TS certification
- Processing method of PPS plastic
- 3, the automobile industry: PPS for automobile industry accounted for about 45%, mainly used in automotive functional parts; ignition, heater, vaporizer, clutch, gearbox, gear box, bearing bracket, lamp, bumper, fan, exhaust system and mirror and lamp seat parts. The utility model can be used for producing an exhaust cylinder, a circulation valve, a water pump impeller, a pneumatic signal adjuster, etc. in place of the metal. 4, household appliances: hot air dryer, hair curler, hair dryer, hair curler, microwave ovens, coffee pots, clothes dryers, electric irons, rice cookers and other protective coatings and parts. 5 、 chemical industry: PPS has good adhesion and corrosion resistance, it is very suitable for chemical equipment lining.Four. Material drying processTemperature: 100~105 DEG CTime: 3hr2 、 injection molding process1) die temperature: 60-80 DEG C2) material barrel temperature: front section: 220~260 centigrade middle section: 290~310 DEG C, rear section: 300~320 DEG CNozzle: 290~300 DEG C3) injection molding pressure: 60~70Mpa4) injection speed: medium speed5) injection molding time: according to the size of the workpiece to determine, in order to fill the mold, and the surface of the basic cooling is preferred
- Would like to ask a few questions?1, waste plastics need to go through a few devices or steps to become plastic particles2, how much would it cost for the whole set of plastic particles? (I want to get a small wire first)3, if the equipment, plastic material can be any processing?4, is there any pollution in the whole process?.5, how about this prospect this year?Please have experienced predecessors to give some experience
- The question you ask is too wide. There are too many plastic parts. First of all, you have to decide what kind of plastic you want to make. We usually have PET PP, PVC, PMMA, ABS, PEAnswer the questions you ask first: 1, the most basic, you should have a crusher, washing machine, particle machine2: I'm looking for in our local welders do, that not what technical content, you will not give them to talk about the price, almost tens of thousands of dollars.
