Q:What are the main plastic forming processes?

The main equipment used for molding compression is to press and mold. The most used hydraulic press is self support hydraulic press. The tonnage varies from tens to hundreds of tons. There is a lower press and an upper press. The die used for compression molding is called pressing die. It is divided into three kinds: overflow mould, half overflow mould, no overflow mold.The main advantage of compression molding is that it can be molded into larger flat products and can be produced in large quantities. Its disadvantage is long production cycle and low efficiency.2. lamination forming. A method of combining two or more layers of material of the same or different material by heating and pressurizing with or without a binder.A layer of floating hot pressing plate is arranged between the movable plate and the fixed plate of the press.The reinforcing materials used in laminated forming are cotton cloth, glass cloth, paper and asbestos cloth. The resins are phenolic, epoxy, unsaturated polyester, and some thermoplastic resins.

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.
