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

(1) urea formaldehyde moulding powder;The resin powder of urea formaldehyde resin, commonly known as electric jade powder, is produced by wet process, such as tree ester, curing agent, filler, colorant, lubricant, stabilizer, plasticizer and so on1 Components(1) resin used for urea formaldehyde resin molding powder by condensation reaction degree is relatively shallow, the resin with low viscosity, easy dipping filler, and can ensure the long production cycle and drying after proper fluidity, condensate in the industrial use of urea and formaldehyde at low temperature (a mixture of dimethylol urea, urea and formaldehyde) are usually used. The ratio of 1:1.5 (molar ratio), the PH=8 (and temperature) 30 - 35 of all dissolved, adding urea oxalate was 0.3% - 0.33% and 0.88% - 0.54% of the oxalic acid, then the occurrence of exothermic reaction, temperature rise, temperature in 55 - 60 degrees, and strictly control the PH=5.5 - 6.5, 60 - 75min by urea formaldehyde resin is required. Because the condensation degree is low, in fact just over addition reaction, condensation reaction is mainly in the curing process.(2) the curing agent used in curing agent and pressing powder requires latent, usually oxalic acid, phthalic acid, two formic acid, benzoic acid, chloroacetic acid, etc.(3) packing material is the most commonly used pulp, followed by wood powder or inorganic fillers (glass fiber, asbestos, mica etc.). The pulp is wood as raw material, with sodium bisulfite, non soluble cellulose impurities to the wood, and then byThat is the pure cellulose bleaching. The amount of filler material for the total amount of 25%-32%, the amount is too small, the pressure of plastic powder fluidity big, product strength is low; on the contrary, the amount of excessive pressure, plastic powder fluidity decreases, the product surface is not smooth, water

Q:What's the best place to use the pillow type packing machine?

In the early communication can be reflected, and sometimes non-standard customized to see the level of Technology

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

A lot of heating machines have to use thermostat

Q:Calendering, extrusion, blow molding, pressing, plastic (vacuum forming) and what is the rotational molding

Plastic forming and processing methodPlastic molding is an engineering technology, involves the plastic into all kinds of plastic products in the process. The transformation process tends to happen in one or more of the following conditions, such as polymer rheology and physical and chemical properties of the change.

Q:What's the fastest packing machine?

Because the packaging machine type is more complicated, according to the state, liquid, bulk, powder, granular packing machine; according to the function of packaging, packaging, packaging machine in outsourcing; according to the packaging industry, food, daily chemical industry, metal parts, textiles and other packaging machine; according to the packing station. A single station and multi station packing machine; divided by automation, automatic packing machine, also has semi-automatic and so on. According to the form of sealing, it can be divided into back sealing type, three sides sealing, four sides sealing, triangle and so on. According to the product form, it can be divided into pillow type packaging machine, vertical packaging machine, vacuum packaging machine, sealing machine and so on

Q:Is there anyone who knows what groups of users of packaging machinery are in general?

This is really not sure, it can be said that any group, as long as the packaging products are required to use packaging machinery. Most of the products are now in need of packing. So it can be said that any group.

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

A small object, small particle, powder, crystal, liquid, suitable for packing

Q:Bread packing machine Product features

4., high sensitivity photoelectric eye mark tracking, digital input seal cutting position, so that the seal cutting position more accurate.5. temperature independent PID control, better for all kinds of packaging materials.6. 、 positioning stop function, no sticking knife, no waste of coating.7. drive system is simple, more reliable work, more convenient maintenance.8. all control is realized by software, which is convenient for function adjustment and technical upgrading, and never falls behind.

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

1. each manipulator is controlled by a single computer. A packaging machine for the completion of complex packaging operations, the need to be completed by a number of robot hand. When the package is completed, the information is monitored and controlled by the computer controlled camera, and the manipulator completes the required actions according to the instructions of the computer program to ensure the quality of the packaging.2. high resolution of material and thickness. In the packaging process, the thickness and material change in packaging materials is not easy for the human eye to identify changes in the design of packaging machinery is often used by the computer control of the camera and the detector to identify the thickness of packing material and material. The camera has now been developed to automatically check and identify pictures of the camera and display it on the screen. At present, the machine in the processing speed can not be changed, the future should be based on the change of the material through discrimination can change the speed, so as to control the work in the optimal state, complete the packaging process in the shortest time, and realize the automatic cleaning, automatic sterilization and automatic cleaning
