Q:What does injection mean?

Heel cast steel. The cast iron is about the same,,

Q:Want to know how to play a complete product, how to calculate the pressure, speed, etc.. Example, GREE electrical appliances series 4002B chassis, how can I transfer the full product?.

(2) debugging of die closing device;1) wipe the mold clean, then carefully and securely installed between the fixed die, and then adjust the length of the slider according to the size of the plastic block, limiting the opening of the moving template.2) adjust the ejector mechanism so that it can push the molding out of the die cavity to the preset distance.3) the clamping force should be adjusted according to the requirements of the processing technology. The die clamping force should be adjusted to the lower limit of the required clamping force.4) adjust all stroke switches to their respective positions, and adjust the closing of the die.5) adjust the speed and pressure of the mold opening and closing die, generally adjust the speed to the pre selection value, then adjust the pressure to the specified value.6) the clamping device can only work on both sides of the injection machine when the safety door is closed, and check whether the machine will stop working when the safety door is open.

Q:What are the service life of domestic injection molding machines and machine tools? How do we calculate depreciation?

I. The depreciation period of injection molding machines and machine toolsArticle sixtieth of the regulations on the implementation of the enterprise income tax law of the People's Republic of China stipulates that, in addition to the provisions of the financial and tax authorities under the State Council, the minimum amount of depreciation for fixed assets shall be as follows:(a) housing and buildings for 20 years;(two) aircraft, trains, ships, machinery, machinery and other production equipment for 10 years;(three) appliances, tools, furniture and so on related to the production and operation activities, for 5 years;(four) aircraft, trains, ships and other means of transport for 4 years;(five) electronic equipment, for 3 years.

Q:What is the problem of Shanghai plastic injection molding machine in the die closing process?

Solenoid valve installed wrong, or out of the oil path is simple along the road, and the solenoid valve is connected to reverse.

Q:I want to know the injection speed of injection molding machine. What is the specific unit?

Each model of injection molding machine according to the diameter of the screw, the pressure size is different, its rated speed is not the same. Velocity means the position of the screw moving in unit time. The unit is CM3/S (cubic centimeter / sec).

Q:Does the injection machine have to use cooling water?

First, the injection molding machine normally work, it is necessary to cooling water.Two. Cooling water is related to the specific heat of molding material, the temperature and weight of melt and the temperature at the time of demoulding. The formula for the required ice water energy of a mold is Q=W * C * T * S. Among them:Q is the required ice water energy kcal / h;W for plastic raw material, weight kg / h;C is a plastic raw material with a specific heat of kcal / kg DEG c;T is the temperature difference between the temperature of the melt and the demoulding of the product;S is the safety factor (usually 1.35 - 2).When a single machine match, the general choice of small values, and when a cold water machine with a number of molds to match when the big value, such as the selection of air-cooled chillers, S should also be elected a big point.

Q:What does an injection maker do?

The main job of the injection molding machine is to operate the injection molding machine to produce the plastic shell. The size of the shell is directly related to the size of the mold. The principle of the injection molding machine is to melt the plastic pellets through the heating system of the injection molding machine into the mold, into the shape of the mold, and then cool down through the cooling channel in the mold, shape, and then release into a product. All rubber products are similar in injection molding, such as soles, cups, finishing boxes, etc.. The work principle is quite the same.An injection molding worker is one of the common line workers. Injection molding workers generally stand up and work harder.

Q:What does the injection machine do?

Injection molding is used to produce plastic products

Q:Vertical injection molding machine in the semi-automatic state, not sol, and sometimes sol is very slow, seems to be very difficult, and sometimes simply do not turn. The problem is that it occurs during normal use, so the temperature should be fine. The parameter should be OK, too. I removed the screw and cleaned it. There was no foreign object. Under manual operation, the sol is very smooth. Consult an expert.

I have encountered such a thing, I analyze the vertical machine tonnage is small, PC material excellent, too sticky. If it's ABS, PVC, PBT and other materials, that's OK, right?

Q:What kind of lubricant does the injection machine use?

The main use of antiwear hydraulic oil, as well as 00-000, extreme pressure grease
