Q:Can you tell me if there are 350 grams of three injection molding machines? How much? Thank you
168 tons, theoretical injection weight: A--335 grams, B--378 grams
Q:General injection molding machine agents need what conditions?
This is to ask manufacturers, each manufacturer of different
Q:What is the back pressure in the injection molding machine?
Jin Xin offers you:Jin Xin explain the injection molding machine screw back pressure what role?Back pressure allows the screw to produce enough mechanical energy in the rotation of the reset to melt and mix the plastic, and the back pressure has the following uses.The volatile gases, including air, are discharged to the outer cylinder.Mix the additives (e.g., toner, color, antistatic agent, talc, etc.) and melt evenly.Homogenizing the melt flowing through different screw lengths.Providing uniform and stable plasticizing material to obtain accurate weight of finished products.The back pressure can make up the melt temperature of injection molding machine barrel, rise and set pressure value associated with a large injection molding machine, screw diameter more than 70mm [(2.75in) of the oil pressure can be up to 2.5-4MPa], but need to pay attention to the oil pressure is too high, or is caused by the melt pressure back pressure resistance induction high temperature molten material in the barrel is too high, this kind of situation for heat sensitive plastics production is destructive.And too high back pressure also caused excessive screw and irregular offside, so that the amount of plastic is very unstable. The viscoelastic properties of offside and plastic screw the screw; offside and melt the stored energy. The more energy, the greater the offside screw distance, the energy stored in the screw stops rotating, suddenly beat back, some thermoplasticPlastic beating phenomenon is more severe than other plastic, such as LDPE, HDPE, PP, EVA, PP/EPDM composite and PPVC, compared with GPPS, HIPS, POM, PC, PPO - M and PMMA, more prone to beating phenomenon. For optimum production conditions, the correct back pressure setting is critical. Proper back pressure setting allows the mixture to be properly mixed, and the offside range of the screw does not exceed 0.4mm (0.016in).
Q:Does the injection machine have to use a manipulator?
Secondly, the performance and ease of use of the robot are evaluated. The performance of the manipulator is usually represented by its velocity and precision, speed and high speed reflected in the rapid response, the need of the implementation of components was studied, especially the cylinder and solenoid valve selection determines the performance. The repeatability is mainly reflected by the machining and assembly accuracy of the mechanical components of the manipulator.
Q:What is the injection molding machine Euromap?
It is divided into vertical, horizontal and all electric type. The injection molding machine heats the plastic, applying high pressure to the molten plastic to make it crack and fill the mold cavity
Q:Injection molding machine maintenance Daquan books catalog
The eighth chapter is about the operation and adjustment of common injection molding machineSection 1 operation panelI. computer operation panel of injection molding machineTwo, Jin PT-160 operating panelThree, Haide HDB-120 operation panelOperation and adjustment of injection molding machine in second sectionsFirst, shock male, Czech tyrants, C series of energy-saving injection molding machineTwo, Jin PT series injection molding machineThree, Hai Debao HDB series injection molding machine
Q:Trouble shooting of injection molding machine
Non thimbleA, the actual location of the mold is not up to the actual setting;B, computer set no thimble or thimble times zero;C, the set of process parameters are incorrect;Detection status of D and thimble electronic ruler;Mechanical damage of E and ejector pin mechanism;F, the valve out of the direction of the valve is charged and spool work is normal.No needleA, computer process parameters;Detection status of B and electronic ruler;C, the working state of the directional valve.Abnormal movements of the meltA, the temperature of the melt tube is not set;B, the process parameters are unreasonable;Detection status of C and electronic ruler;D, the working state of the directional valve;E, melt into the cylinder with hard objects, stuck screw;Behind F, the barrel does not lead to water transport water, feeding inlet temperature is too high;G, glue back pressure is too large, check back pressure valve;H, adhesive motor or transmission shaft failure;I, hopper no material;The ejection motion is abnormalDetection status of a and electronic ruler;B, the working state of the directional valve;C, speed, pressure, position and time setting of process parameters;D, melt tube or nozzle temperature is not set;E, foreign body stuck in the melt tube;F, nozzle blocked;The G, the firing point and the stop switch do not work.Semi automatic and fully automatic working state is out of orderThe first observation is the problem in which a working condition, and then checked for specific actions, full automatic working condition but also to check the electric eye or time setting.
Q:What is a vertical injection molding machine?
Features of vertical injection molding machine:1, an injection device and a locking device for processing in the same vertical center line, and the mold is opened and closed down. It covers only about half of the horizontal machine, so it is converted into an area of about two times.2, easy to insert molding. Because the surface of the mold faces upwards, the insert is positioned easily. The template fixed template movable machine, belt conveying device and mechanical hand combination of words, can easily realize automatic insert molding.3. The weight of the die is supported by the horizontal plate for opening and closing movements. The phenomenon of the front falling of the horizontal machine caused by the gravity of the mould can not occur, so that the mould can not be opened and closed. Conducive to durability, mechanical and die accuracy.4, through a simple manipulator can be taken out of each plastic cavity, is conducive to precision molding.5, the general mold locking device is open for opening around, easy to configure all kinds of automation devices, suitable for complex, sophisticated products automatic molding.6, the drawstring lose conveying device is easy to achieve string moldthe middle installation, easy to realize automatic molding production.7. It is easy to guarantee the consistency of resin flow and die temperature distribution in mold.8, equipped with rotating table, moving table and tilt table and other forms, easy to insert molding, mold combination molding.9, small batch production, the mold has the advantages of simple structure and low cost, and easy to uninstall.10, has withstood the test of many earthquakes, vertical machine because the center of gravity is low, the relative horizontal machine shock resistance is better.
Q:What does an injection maker do?
It's hard to operate machines!! Not only the smell of the glue is bad, but also the temperature of the machine is very high. If you don't care, you will hurt yourself
Q:Haitian injection molding machine alarm, hydraulic insurance exception, what are the reasons?
The problem is on hydraulic oil, such as insufficient hydraulic oil, hydraulic oil containing impurities. Check, either add hydraulic oil, or replace the hydraulic oil.
