Q:What are the main functions of packaging machinery?

Eight main functions of packaging machinery and equipmentPacking is a necessary condition for products to enter the circulation field

Q:What is the delay time of the packer's cross sealing?

The sealing time is how long the delay is when the sealing dies are joined together.

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:How does the pulp solidify? What additives do you need? Curing agents? Or what do you need as binders?

Urea formaldehyde resinUre-aformaldehyde resinsUrea formaldehyde polymer. Also called urea formaldehyde resin. The cross-linking English abbreviation UF. molding, the product is insoluble and infusible thermosetting resin, urea formaldehyde resin cured phenolic resin than the color of light, translucent resistance, weak acid and weak alkali, good insulation properties, excellent wear resistance, low price but, in case of strong acid and strong alkali decomposition, weather resistance is poor. The name Beetle. urea and 37% formaldehyde aqueous solution can be obtained by the polycondensation of linear urea formaldehyde oligomer in catalytic acid or alkali industry, with alkali as catalyst, reaction temperature of about 95, the molar ratio of formaldehyde to urea as 1.2.0, to ensure that the resin curing reaction. The first step to generate and dimethylol urea, then hydroxymethyl amino and soluble resin by further condensation, if by acid catalysis, easy to cause the product to be stored to gel. In neutral condition. The linear UF resin for ammonium chloride Curing agent can be cured at room temperature. The molding powder at 130 to 160 DEG C heat curing accelerators such as zinc sulfate, trimethyl phosphate, two oxalic acid ethyl ester can accelerate the curing process. The urea formaldehyde resin is mainly used in the manufacture of molded plastic manufacturing, daily life products and appliance parts, also can be used as adhesive, paper and fabric sheet the pulp, plywood, decorative board and so on. Because of its light color and easy coloring, products often colorful and magnificent.

Q:Which friend is an expert in mechanical equipment or a better understanding of sealing machines? Tell me how to identify the equipment

There are PLC control ah, if it is fully automatic, then ask the quality of sealing ah, it is best to let manufacturers give you a live demonstration, the soft power depends on the size of the factory, ah, after-sales service ah!

Q:How much is the tableware wrapping machine?What's the price of the tableware wrapping machine?

Tableware packaging machine machine standard price of about 38000, excluding tax, tableware packaging machine is designed for tableware (e.g., chopsticks, bowls, dishes and so on) a modern packaging machinery packaging, this machine is mainly composed of conveyor, packaging machine, output machine, shrink machine, composed of four parts.

Q:What does the mechanical equipment include?

Q:What is a packaging machine?

Meet the needs of mass production and meet the requirements of clean sanitationUsually some non-standard equipment, the common is pneumatic and simple combination of electrical components, to meet the requirements of factory automation

Q:What is the price of a small jujube packing machine?

Mainly see what some requirements, automatic metering packaging or vacuum packaging machine, after understanding can determine the price.

Q:Working principle of packing machine

Then, by heating the sealing part of the bag bottom sealing, again is material, the material into the packaging machine, and then sealing, finally cut off, a complete package came out, this is the working principle of small vertical packaging machine.
