Q:Large injection molding machine to block reuse
First you have to put the head while hot into slices,
Q:What are the features of servo motors for injection molding machines?
1, energy saving2 、 quick response and high production efficiency,3 、 pressure stability precision4, high repeatability, saving material5 、 low temperature rise of oil temperature6, low noise
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:Injection molding machine rankings?
Haida machine, A Well-Known Trademark in China, national Mianjian products, high-tech enterprise, Zhejiang famous brand, Zhejiang famous trademarks, China Plastic Machinery Industry Association executive director of the unit.
Q:Injection molding machine pressure, speed, back pressure unit is what and their relations with other international units
Pressure injection molding machine, we often talk about the pressure, strictly speaking, the pressure is equivalent to the middle school, which bear the force per unit area, the international regulations, under 1N in the area of 1 square meters (Newton) on the pressure of 1Pa (Pascal), as long as know the multiple relation, it is easy to obtain the pressure (strong the conversion unit):1m=100cm=1000mm1kg = 10N1M (megabit, million) Pa=1MPa=1000k (1000) Pa=1000000PaSo 1MPa=10kg/cm^2=1N/mm^2We often use international non legal units of measurement: 1bar=10^5Pa=1kg/cm^2=0.1MPa (bar) and 1Torr=133Pa (Torr)The pressure gauge of the injection molding machine, the most used is MPa, bar, kgf/cm^2 unit, need to be reminded that, behind the two units is not our statutory units of measurement, but the world especially Europe and the United States is often used, because many components of the injection molding machine for imported components, including the pressure gauge, so we will often see illegal dial pressure gauge measurement units.In the injection molding machine, the injection molding machine pressure and back pressure unit is MPa, speed (actually refers to injection rate), the unit is g/s, or cm^3/s
Q:Full electric injection molding machine and hydraulic injection molding machine
I will choose hydraulic, full electric high cost, the main reason
Q:How to see the precision of injection molding machine? Thirty
General precision injection molding machine has two indicators: - is the product size repeated error, and the other is the repeated weight error of the product. The former is difficult to compare because of the size and the thickness of the product, and the latter represents the comprehensive level of the injection molding machine manufacturers. Repeat error weight like ordinary injection molding machine in 1% or so, the better machine can reach O.8%, less than 0.5% of the precision machine, less than 0.3% for ultra precision machine, reported the highest international level is less than O.15%.
Q:What are the equipments around the injection molding machine?
Commonly used are: mold temperature machine (water diversion, oil type), frozen water machine, dryer (drying equipment has centralized drying group), cold water machine, suction machine, crusher, mixer and so on

Q:Injection molding machine products shrink, how to solve?
The working principle of injection molding machine and injection syringe with similar, it is the use of screw (or piston) thrust, the plasticizing good molten state (i.e. viscous flow) plastic injected into the mold cavity closed good after curing stereotypesmade the process of the products. Injection molding is a cycle process, each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - mold cooling - die opening pieces. Take out the plastic parts and then close the die for the next cycle. Action procedure: die, pre molding, pour, retract, nozzle (nozzle forward), injection, pressure protection, nozzle (back of nozzle), cooling, mold opening, ejecting, opening, taking the workpiece, closing the door, closing the mould, closing the mould, closing the mould, closing the door, closing the mould and closing the mould.Product shrinkage problem, if it does not involve other reasons, only injection molding process, the holding pressure is the most critical factor. Is the purpose of holding pressure when the screw after the injection, and exert a certain strength to the screw is held in place for a period of time, namely after injection and then squeeze some material into the cavity and prevent plastic reflux is not solidified completely to shrink. Keep the pressure big, the density of the plastic in the cavity is big, the surface is smooth and full. Shrinkage is positively related to size. Position, pressure, speed, the relationship between the three is connected, and in the adjustment of the machine should be based on the size of the product, the location of glue points, methods, raw materials, types and so on. For example, PC material, poor liquidity, injection molding must use high speed, high pressure, or easy to fight. And nylon or PP, the speed is too fast, the lack of mold exhaust, it is easy to generate coke.
