FAQ

I'd like to open a waste plastics processing plant. What should I pay attention to? What machines are greener? Can you find 5T every day?
Raw material blowing factory is estimated to have a lot of it. You can go to Tongcheng to see, plastic town ah...
PPO plastic mold commonly used steel processing?
Application range6 polyphenylene ether is high strength engineering plastics development 60s of this century, it has high mechanical strength and creep resistance; excellent electrical properties, high temperature to 120 DEG C, and in a wide temperature range, stable size, mechanical properties and electrical properties change little; absorption of water vapor is very small. Cooking. Widely used in electronic, electrical components, medical equipment, cameras and office equipment, and so onCommon problem7 injection molding process characteristics and process parameters of modified polyphenylene oxidePolyphenylene oxide (also known as: polyphenylene oxide) [PPO] has good chemical stability, low creep, aging resistance, and it is not easy to burn. Because of its good water resistance, polyphenylene oxide is widely used as an engineering plastic.The major disadvantages of polyphenylene oxide are: poor flowability of melt, difficulty in forming process, tendency of cross linking, expensive price, easy stress cracking and unstable impact strength.
I am going to work as a worker in a plastics factory. I wonder if the work inside it is very polluting. Is there any harm to the health?
Plastic products factory work on the human body will be a number of pollution, direct pollution, there are indirect pollution, but still depends on what material and what post.Plastic products generally include plastic batching, molding, machining, bonding, finishing and assembly. The latter four processes are carried out after the plastic has been molded into products or semi-finished products. It is also called plastic two times processing.Plastics burn easily and produce poisonous gases when they burn. For example, toluene combustion produces a small amount of polystyrene, this substance can cause blindness, vomiting and other symptoms of inhalation, PVC combustion will produce toxic gases, hydrogen chloride in combustion, is a high temperature environment, will lead to plastic decomposition of toxic components, such as benzene etc..In December 31, 2007, the general office of the State Council issued a notice on limiting the production, sale and use of plastic shopping bags, which was called "plastic restriction order" by the masses". The reason is that plastic shopping bags, while providing convenience to consumers, have caused serious waste of energy, resources and environmental pollution due to excessive use and recycling. As we all know, coupled with the large volume of waste plastic foam, garbage recycling channels are not smooth and other reasons, the pollution problems can not be underestimated. But because of the low cost of plastic foam and easy to use, some well-known online shopping shops still continue to use.
What are the standard tolerances for engineering plastic products machined (e.g. lathes, milling machines)?
No, look at the drawings, requirements, no note tolerances, drawings should be marked, and if there is no mark, then there is a problem with drawings. Drawing requires that all elements be annotated.
Method for producing plastic product
Plastic products generally include plastic batching, molding, machining, bonding, finishing and assembly. The latter four processes are carried out after the plastic has been molded into products or semi-finished products. It is also called plastic two times processing. Key links in plastic processing of plastic products. The various forms of plastic (powder, granular, solution or dispersion) made products or blank of desired shape. As many as 30 kinds of molding method. Its choice is mainly determined by the type of plastic (thermoplastic or thermosetting), the starting form, and the shape and size of the product. Plastic processing thermoplastics commonly used methods are extrusion, injection molding, calendering, blow molding and thermoforming, etc., plastics processing thermosetting plastics generally use molding, transfer molding, injection molding. Lamination, molding and thermoforming are the processes of forming plastics on a flat surface.
What kind of equipment do you need for the food market? How much would you like to invest? What about the profit?
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,
What plastic products are made out of machines? Is it an injection molding machine?
According to the process, there are many kinds of processing equipment, not only the injection molding machine, as well as extruder.
One hundredUrgently!!!Find a kind of plastic that can be used for machining. The better the machining performance, the cheaper the better.Used for the principle model, in the past, when the school practice, used a milky white opaque material, feel good, but I do not know what the name.Copy paste party, do not come to a great God level, experienced best. Kneel thanks!Can PVC be used for machining? As long as you can get on the lathe. If there is a better buy channels.To pipe, diameter 20,40, 65mm 1 each. The lengths are 450450335mm.Can PMMA (acrylic) stick be machined? The supervisor told me that nylon rods do not work and that moisture size is not guaranteed.Then suggest I use this... Which is better than PVC? Thank you
PSU plastic, this plastic can be machined. The factory where I practiced has used detailed parameters. You can check it online
