Q:What are the main plastic forming processes?

Plastic processing is a complex process, generally divided into the following processing methods:In order to improve the quality of the product and improve the molding efficiency, the pre pressing is used to press the powder or fibrous molding material into a certain shape in advance.Preheating, in order to improve the processing performance and shorten the molding cycle of molding plastics, the molding plastics are heated prior to molding.Molding in the mold to add the required amount of plastic, closed mold and exhaust, at the mold temperature and pressure to maintain a period of time, and then release mold cleaning operations

According to the product form, it can be divided into pillow type packaging machine, vertical packaging machine, vacuum packaging machine, sealing machine and so on

Q:Whether you can press paper plastic molding after PET

Sure；Note cards must be coated with plastic oil;Can use blister sealing machine or high frequency plastic welding machine hot pressing;

Q:What does that mean when the composite material is pressed and molded? What are pressing forming? What are the characteristics of press molding equipment? Its development

Different conceptsCompression molding refers to hot forming: mainly for thermoplastic materials (sheet), the use of hot forming machine, Blister molding, I think it should also be considered as a branch of hot stamping, vacuum or high-pressure gas will be used to assist. Hot pressing sheet forming a relatively small depth, relatively simple structure, low precision products, such as packaging materials, plastic pallets, plates in the dishes and so on. There are also forming plate pressing molding (lamination)

Q:The role of food packaging machinery

3) to achieve manual packaging can not achieve the operation, some packaging operations, such as vacuum packaging, inflatable packaging, body packing, isobaric filling, etc., are manual packaging can not be achieved, can only be achieved by mechanical packaging.(4) can reduce labor intensity, improve the working conditions of the labor intensity of manual packaging, such as volume, weight heavy manual packaging products, both the consumption of physical strength, and safety; and for small and light products, due to high frequency, easy to make the action monotonous, worker occupation disease. Carton folding machine(5) in favor of labor protection for some serious impact on health products, such as serious dust, toxic products, irritating, radioactive products, manual packaging is a health hazard, and packaging machinery can be avoided, and can effectively protect the environment from being polluted.(6) it can reduce the cost of packing and save the storage and transportation expenses. It can reduce the volume and reduce the packing cost by compressing and packing the loose products, such as cotton, tobacco leaf, silk and hemp. At the same time, due to the reduction of large volume, in order to save storage capacity, reduce storage costs, is conducive to the transport.(7) ensure product health of certain products, such as food and drug packaging, according to the health law is not allowed to use manual packaging, because it will pollute the products and packaging machinery to avoid direct contact with the staff of food and medicine, to ensure the quality of health.

Q:A & B two sets of packaging machines, at the same time packaging quality of 500 kilograms of goods

(3) large variance, indicating that this group of data volatility, variance is small, volatility is relatively stableAnswer: (1) a = x (501+500+503+506+504+506+500+498+497+495), 10=501,B = x (503+504+502+498+499+501+505+497+502+499), 10=501;(2) S2, =1/n[(501-501) 2+ (500-501) 2+... + (495-501) 2]=12.6,S2 B, =1/n[(503-501) 2+ (504-501) 2+... + (499-501) 2]=6.4;(3) a b > S2 dreams S2,The quality of R B packaging machine 10 bags of sweets is relatively stable.Comments on the subject, mainly on the average number, variance calculation, and their significance, the correct memory formula is the key to solving problems
