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:The role of packaging equipment in packaging equipment

(4) it can reduce labor intensity and improve working conditionsThe 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.(5) labor protection for workersFor 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 packing cost and save the storage and transportation expensesFor loose products, such as cotton, tobacco, silk and hemp, the compression packing machine can reduce the volume and reduce the packing cost. 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.

Q:Where is secondhand corrugated paper packaging machinery available?

Carton factory and general production enterprise is different,General business is to face direct consumers, the need for their own sales network, sales staff, sales means......And carton factory as long as accurate manufacturers, show their means, get business.Maybe you walked into a food factory, an electrical factory, a furniture factory, a toy factory...... Can be your client.With business, but also to choose their own plant.Cartons are flammable and afraid of water. This is the disadvantage of cartons. If handled properly, there will be no problem.Site is best to avoid low-lying and rainy lots of water, the cardboard should not be piled directly on the ground, the bracket is a good choice.No smoking in the factory area, no open fire, and good fire fighting equipment, so as to ensure the safety of production.The size of the initial plant is best to be 500 square meters, or larger, smaller.
