Q:What are the main plastic forming processes?

5. low pressure molding. A touch or laminating method using a molding pressure equal to or less than 1.4 mpa.Low pressure molding is used to make reinforced plastic products. Reinforced materials such as glass fiber, textiles, asbestos, paper, carbon fibers, etc.. Most resins used are thermosetting, such as phenolic, epoxy, amino, unsaturated polyester, silicone and other resins.Low pressure molding includes bag pressing and spraying.(1) bag pressing forming. A method of forming a workpiece by applying fluid pressure to an elastomeric plastic between a rigid mold and an elastic bag by means of an elastic bag (or other flexible diaphragms). According to the different methods caused by fluid pressure, can generally be divided into pressure bag molding, vacuum bag molding and autoclave molding etc..(2) spray forming. When molding reinforced plastic products, a method of spraying a short cut of fibers and resins simultaneously onto a mold and solidifying them into an article by means of an airbrush is described.

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

Urea formaldehyde resin is a water-soluble resin, easily cured, the cured resin colorless, non-toxic, good light resistance, long-term use does not change color, heat molding will not change color, can add various colorants to prepare various brightly colored products.Urea formaldehyde resin is hard, scratch resistant, weak acid, weak base and grease. It is cheap and has certain toughness, but it is easy to absorb water, so it has poor water resistance and electrical properties, and its heat resistance is not highThe use of urea formaldehyde resin is widely used in plastic, mold, laminated plastic, foam, also can be used for the production of water-soluble adhesive, the adhesive for wood; fabric shrinkproof and crepe treatment agent; used as a varnish of paper, in order to improve the wet strength of paper. The following is a simple Shaoxing on it the application of the plastic.

Q:What are the packaging machines that use temperature control watches?

A lot of heating machines have to use thermostat

Q:What are the packing machines?

Heat shrink packaging machine, mask packaging machine, pillow type packaging machine, food packaging machine, I suggest you can go to see

Q:The role of packaging equipment in packaging equipment

Some 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.(8) it can promote the development of related industriesPackaging machinery 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, any discipline problems will affect the overall performance of 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.

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:The difference between wrapping and bagging is explained from the packaging method, and the difference of the working principle of the packaging machine is analyzed

Wrapping machinery should have rolling, holding, brushing, packaging machinery, bagging, weighing, sealing.

Q:What is the design basis of automated packaging?! Just for today!

Increase productivity and reduce process costGerman packaging machinery, especially beverages, beer filling machinery and food packaging machinery, with high speed, complete sets, high degree of automation and good reliability and so on. Beverage filling speed up to 1200 bottles / D, when the cigarette packaging 12000 / min.. Increasing the speed of the machine is a complex problem. The faster the piece production cost is, the higher the use area of the workshop is. In addition, the speed of the motor is limited, so do not think how fast, how fast. In general, the speed increase by 15%, 20%, will lead to a series of complex problems. In addition to increasing the speed, the productivity can be solved from other channels:1. continuous or long work. Packaging machinery works a batch type and continuous type, design, design should strive for continuous work, also can improve the productivity; one device may also have multiple production lines, the production of the same product or several different products, but must improve the reliability.2. reduce scrap rate and provide fault analysis system. The loss of waste to production is enormous, not only product loss, but also material loss. So try to force to reduce the rejection rate; packaging machinery sale should also provide maintenance services for the fault analysis system, the modal analysis is carried out to find fault, or through the Inter network for remote diagnosis, the maximum to meet customer needs. In the future, the packaging machinery will be further intelligent, that is, the equipment itself to find fault, to solve their own failure, to reduce waste rate and failure rate, so that the normal productivity can be improved.

Q:Ask a mechanical problem, the waste film recycling in the packaging machinery is a new film packaging, after cutting, then use the roller to recycle the waste film. Encounter a

It is recommended not to check the cursor, if the speed is stable, with the amount of speed (recommended to detect the angular speed of the drum) to detect, a closer speed will be smaller, you can do the implementation of the operation. If the speed is unstable, you can only use the scale. But the 2 one is marked out. The beginning and the end. A colleague detects the difference in velocity between the 2 displacements. The difference in speed means that the film is stretched and the excessive velocity is stopped directly, which means that the film has been stretched

Q:What machine does the packing carton machine have?

Packaging equipment including: automatic strapping machine, automatic sealing machine, winding (wrapping) machine, sealing and cutting / shrink machine, vacuum packing machine, automatic strapping machine band and hand tools. Transport equipment mainly include: conveyor belt, roller conveyor, conveyor chain plate, plug-in production line, chain conveyor, conveyor belt etc..
