Q:What are the main plastic forming processes?

3. cold pressing molding. Cold pressing molding is also called cold pressing sintering molding. The difference between the cold press molding and the ordinary compression molding is that the material is pressurized and molded at room temperature. The mold after release can be heated or cured by chemical action. This method is used in the forming of polytetrafluoroethylene and some high temperature resistant plastics (such as polyimide, etc.). The general process is three steps of billet sintering cooling.4. transfer molding. Transfer molding is a molding process for thermosetting plastics. When molding, the mold is heated and softened in the heating chamber and then pressed into the mold cavity where it has been heated. According to the different types of transfer molding equipment form: trap type; the tank; the piston.The requirement of plastic molding for transfer molding is that the plastic should have a greater fluidity before reaching the curing temperature, and the curing rate must be faster at the curing temperature. Phenol, melamine, formaldehyde and epoxy resins can meet this requirement.Transfer molding has the following advantages: less waste edge products, can reduce the processing quantity; second molding with fine or brittle insert and perforation of the products, and can keep the insert and the hole position is correct; the product performance is uniform, accurate size, high quality; the mould wear small. The disadvantage is that the manufacturing cost is high compression mold die; the plastic loss; the fiber reinforced plastics for fiber orientation and anisotropy; and around the insert around the plastic, sometimes due to melting is not strong and make the products according to the strength reduction.

Q:What is the working principle of the pillow packing machine?

In fact, the special machine is often better than the packaging of the compatible machine. A packing machine should be packed in no more than 3-5 varieties. What's more, the products with the larger size and the difference in size should be packed separately as much as possible.

Q:Packaging machine knife cut out of the mouth is uneven, always inclined, so adjust, now tune not come back, or is unable to cut off, or die!

Change a new one, in fact, the knife is very simple, and the ordinary knife is very cheap.If you don't understand, you can ask me

Q:What are the packing machines?

Glass glue category of automatic and manual soft packing machine, chemical, I do not know what you are talking about? You can go and have a look.

Q:What does the mechanical equipment include?

Hydraulic lifting track machineHydraulic tamping machine, rail sawing machine, rail machine

Q:What kind of reducer is commonly used in packaging machinery?

Generally speaking, gear reducer, planetary gear reducer, and the most common one, these equipment power is relatively small, and some need to take the brakes of the motor reducer

Q:Predecessors please point out: what is the future of packaging machinery industry?

Hello, in recent years, Chinese packaging industry, although the annual growth rate ranked in the traditional industry for the first time, but in line with the international market, to accelerate the development of packaging technology, make its development to the economic, efficient, multi-functional direction. According to the development plan of Chinese national economy and to realize well-off life level, this year a few years for the packaging industry, the food industry to provide equipment for 100 billion yuan to 200 billion yuan, 80 billion yuan to 100 billion yuan to provide equipment for the "vegetable basket", this is a good opportunity for development of enterprises. At the same time, I learned from the relevant ministries, "95" period, will invest 10 billion yuan in the packaging industry to support and transform large and medium-sized packaging enterprises.

Q:The role of food packaging machinery

(8) can promote the development of packaging machinery related industry is a comprehensive science which is related to many subjects, materials, process and equipment, electronics, electrical appliances, automatic control and other related disciplines, requires the simultaneous and coordinated development, the overall performance of any discipline problems will affect the packaging machinery. Therefore, the development of packaging machinery will effectively promote the progress of related disciplines. In addition, in order to meet the needs of high-speed packaging machinery packaging, the relevant front and rear processes are bound to adapt, and also promote the simultaneous development of related processes.Fig. 3 is a flow chart of liquid filling. With empty bottles of boxes stacked on pallets, by the conveyor belt to depalletizers, will remove the tray one by one, the box with the conveyor belt to the machine, remove the empty bottles from the box, empty by the conveying belt to the washing machine, after cleaning, and transported to the packing machine next to filled with beverage bottles into them. The empty bottles removed from the unloading machine are sent into the bottle washing machine by another conveyor belt for disinfection and cleaning. They are tested by the bottle inspection machine and conform to the cleaning standard and then enter the filling machine and capping machine. The beverage is bottled from a filling machine. Packed beverage bottle capping machine with the sealed and transported to the labeling machine labeling, (see pictures) with various beverage bottle filling line of the process is similar. But because of the different nature of beverage, the filling machine and capping machine are also different.

Q:What is a packaging machine?

Packaging machinery refers to the machinery that can complete all or part of the product and commodity packaging process. The packaging process includes filling, wrapping, sealing and other main processes

Q:Three dimensional packaging machine, transparent film packaging machine, transparent film three-dimensional packaging machine industry standards
