Q: Types of plastic machinery: There are many kinds of plastic machinery. According to the processing process is divided into extruder, injection molding machine and blow molding machine three major categories. In 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 pipe, rod profiles, also can be used for plastic modification and granulation.The basic mechanism of extrusion is simple - a screw rotates in the barrel and pushes the plastic forward. 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.It is divided into single screw extruder and twin screw extruder. The injection molding machine is injecting molten plastic into the mold, cooling after the product. The use is very extensive, according to the different use of plastic, where is different. The injection molding machine is used in processing machinery and plastic processing industry the largest amount, not only a large number of productsCan direct production of injection molding machine, and it is composed of injection stretch blow moulding equipment key.

Q: What are the methods of forming plastic products introduced in this course?: 6 、 heating moldingHeat - forming thermoplastics are used to heat the plastic sheet into an elastic state and then press it to form a mold attached to the mold. Production of dishware, disc type products.7, foaming moldingThe foaming molding adds the foaming agent to the foam, then the foam is injected into the mold and is solidified into a product. The utility model is used for making cushioning packages for precise instruments and meters.8, moldingMolding for thermosetting plastics. This is a powder, flake or granular thermosetting resins and additives, directly close mold in mold, heating, pressurizing, plastic and liquefaction, chemical reaction and curing, cooling after the products. Producing plates and electrical appliances, machinery parts,9, casting jade moldingCast molding for thermosetting plastics. The molding powder into the barrel heating to heat plasticizing, pressed into the mold, and the product complete solidification under pressure. Complex products production needs to block metal objects.10, casting moldingCast molding is used to heat resistant plastics. It is a thermosetting plastic that is plasticized and injected into the mold. It is cured at atmospheric pressure, cooled and released

Q: Plastic POM POM generally used for the production of what plastic products?: Polyacetal (POM)It is crystalline thermoplastic plastic. It has a melting point of 165~175 degrees centigrade and is close to metal in nature. It is generally referred to as plastic steelAdvantages 1, with high mechanical strength and rigidity2, the highest fatigue strength3, environmental resistance, organic solvent resistance is good4 、 resistance to repeated impact5, widely used temperature range (-40, ~120 Celsius)6, good electrical properties7. Good recovery8. It has good lubricity and good wear resistance9, size stability excellentDisadvantages 1, if the processing process for a long time under high temperature, easy to thermal decomposition2, no self extinguishing3, acid resistance is poor4, forming shrinkage is bigUse electronic appliances: washing machine, juice machine parts, timer componentsCar: handlebar parts, power window partsIndustrial parts: mechanical parts, gears, handles, toys, screws

Q: What is the function of adding filler in the processing of plastic products?: 1., increase the strength: with glass fiber, can greatly increase the mechanical properties of plastics, tensile strength, bending strength, impact strength2., reduce costs: without reducing the strength of plastic, the addition of some fillers, such as talc, calcium carbonate, etc., can reduce the cost of plastics, but also increase the strength of the role.3., flame retardant effect: add flame retardant can be made into refractory plastic products.4. anti-aging: the addition of antioxidants can increase the anti-aging properties of plastics.5. lignite wax: to improve the flow of plastic, improve injection molding effect.

Q: What machines do you need? Where can I get the raw material? Thank you: Now online can buy, of course, the machine on the spot to look goodCup making machine, bowl making machine, printing press, drawing machine, almost

Q: 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 is basically non-toxic, but there are several special raw materials, heating will produce toxic gases, but little harm.

Q: I found that the plastic bags and food bags used in the county town of my work are from abroad. I would like to open a plastic bag processing plant. What kind of machines do I need?. How much is it (cheaper, smaller per day)?. Where does the raw material go in?. The main market for vegetables; small bags for small food. Who will answer in detail?. Thank you: Recommended Xiangxi inspection, old plastic easy to do, but have no production, proposed to do environmental protection cloth generation.

Q: How much do you need for it? How about the raw material?: The production of plastic sandals is the use of injection molding machine, injection molding machine in general to choose 500g-1000g, matching plastic crusher, drying machine, injection molding machine that usually adopts water cooling mold, also need cooling water system.

Q: What equipment? How much money do not.. at first. There are several sets of injection molding machine can be about 2... Mainly plastic injection molding. The ABS PA PE PP PVC... Etc. in this area. Please know that a friend told Kazakhstan. Thank you.: 3. cooling tower or water cooler {if cooling pool is small, buy}The production material crushing and recycling of the 4. mill {}5. mould temperature machine {product on mold temperature requirements higher, buy}6. oven {dry on the material, it is recommended to buy directly installed on the machine, drying faster, floor type, because there are several kinds of materials, while drying, the temperature is not good control.7. blender {material color or when adding material}8., the mold should be loaded big gourd, small mold can buy a lifting trolley, a set of mold tools.

Q: When the engineering plastics in the processing, because it is not often around breaking chip, tool and workpiece, not only affects the working efficiency, but also the workpiece surface galling, do not know can not think of a way from the cutting tool and cutting amount? Who can give me some good advice? Please.: Angle of feed, generally use 60 degrees bevel angle, the amount of cutting does not exceed 1MM. Also, adjust the cutting speed.
