Q: What is the percentage of nozzles in injection molding machines?: According to the 100 degree metaphor, the setting 50% is 50 degrees

Q: What is the function of the temperature control box of the injection molding machine? Thank you: Control the heater to keep the colloidal particles in molten state

Q: The working principle of injection molding machine: 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 include: quantitative feeding - melt plasticization - pressure, injection - filling mold cooling - die opening pieces. Take out the plastic parts and then close the die for the next cycle.Injection molding machine operation items: injection molding machine operation items, including control keyboard operation, electrical control system operation and hydraulic system operation three aspects. The injection process, feeding action, injection pressure, injection speed, ejection type, temperature monitoring, injection pressure and back pressure adjustment are carried out respectively.The molding process of the general screw injection machine is first granular or powdered plastic into the machine barrel and then through the rotation of the screw and barrel wall heating the plastic as molten state, then the machine mold and the injection seat moves forward, to close the mold gate nozzle, the pressure oil through to the injection cylinder then, the screw to move forward at a high pressure and speed will melt into the closed mold temperature low, after a certain period of time and pressure (also called pressure), cooling, the curing, can remove mold products (pressure to prevent molten material the reflux, supplementary materials, to ensure the products with the mold cavity and the density and size tolerance in a certain cavity).

Q: Injection molding machine products shrink, how to solve?: Injection pressure, holding pressure, speed, back pressure, temperature, glue content, inlet and die temperature

Q: What an elder brother knows how nitrogen injection is going on. What should I pay attention to?: 1. the operator must undergo good safety education.2. operate strictly according to the operating rules of equipment.3., when the valve operation, wear protective equipment: masks, gloves, etc., to prevent frostbite.4. check the safety valve and pressure gauge once a year, check the riot film every two years, check and record the records.5. when the nitrogen emissions, people should stay away from the drain, otherwise, long time suffocate easily.6. in the obvious place to hang around the nitrogen tank "trespassers", "dangerous" and other warning signs.7. freezing on nitrogen pipe, no heavy blow.8. check the nitrogen tank every day and find the problem in time.9. always keep the nitrogen tank clean and free of oil and grease.10. equipment should be cut off for a long time without gas.

Q: How can the injection machine be set with parameters?: 4. check the cooling pipe for long distance flow, and the oil cooler and barrel end of the cooling water jacket into the cooling water.5. before the injection machine operation, check whether there is lubrication in each moving part, and add enough lubricating oil.6. turn on the heater and heat the barrel. When the temperature of each section meets the requirements, the insulation will be kept warm for a period of time to keep the machine temperature stable. Holding time varies according to the requirements of different equipment and plastic raw materials.7. add enough plastic to the hopper. According to the injection of different plastic requirements, some of the raw material is best to go through drying.8., the heat insulation cover on the cylinder can be covered, so that the electric energy can be saved, and the service life of the electric heating coil and the current contactor can be prolonged.Operation process1., not for convenience, and arbitrarily cancel the role of security doors.2. pay attention to observe the temperature of the pressure oil, the oil temperature should not exceed the prescribed range. The ideal working temperature of hydraulic oil should be kept between 45-50 degrees centigrade, which is suitable for the range of 35-60 centigrade.3. attention to adjust the travel switch, to avoid the machine in the action of impact.End-of-job1. after the injection molding machine operation is completed, the cylinder should be cleaned of plastic, to prevent residual oxidation or long-term thermal decomposition.2. should be open to the mold, the toggle mechanism is in the locked condition of time.3. workshop must be equipped with lifting equipment. When handling dies, care shall be taken to ensure safety in production.

Q: What do you mean by the "starting position and time" of the injection molding machine?.: It's the way to switch from glue to pressure. See if it's a shot position, or time, or time + position.

Q: Process knowledge of plastic injection machine head: The utility model has the advantages of: two face wear less, good plasticization. Disadvantages: outer wear quickly, and the barrel bore tolerances or when the debris falling into the barrel in the easy to cause the whole screw does not turn over the other is like. The apron will accelerate the cylinder bore wear. A rubber ring outer wear slower without fork and because it is not how to rotate in the pre plastic, but both ends of the surface wear, if you want to do PVC or PC and other plastic material, with the rubber ring is better, because it can avoid the dead corner so as to avoid the buildup the dark spots. Transparent injection molding products of plastic head ring: three meson screw head small overall smooth surface, in addition to the assembly part outside any one can see the front of the place can not have right angle corner, all parts should be based on the angle of smooth transition. Because the right angle corner, easy crack is not that also easy to make accumulation of materials. The material flow is not clear. For a long time to have three small yellow spots, usually is the most prone to yellowing of the site, do a lot of transparent PC.PMMA products are for three sets of design is not good, resulting in yellow.

Q: Can you tell me if there are 350 grams of three injection molding machines? How much? Thank you: Small equipment each company has also ten it this brand is almost a domestic brand quality and sea character generation

Q: Commissioning process of injection molding machine: 3. calculate the relative viscosity of the plastic with the reciprocal of the filling time multiplied by the peak pressure value. The reciprocal of the filling time is the abscissa, the relative viscosity is the ordinate, and the relative viscosity is plotted. The viscosity curve can be found in the low speed high speed changes more, little viscosity change, find a middle viscosity curve trend in value from flat as we used for the production of fire, (also can be judged according to the change of filling time of plastic viscosity stability when the filling time changes, the peak pressure is small) to overcome the rubber mold flow resistance when the pressure, but also beer pieces of the actual pressure, we use this value is greater than 10% for injection pressure.4. determine the pressure and speed, then come to the switching point, do the packing and feeding in beer 95% ~ 99% position switch for holding position. (padding should be controlled by position rather than pressure or time)5. the filling time should be constant, the injection time is longer than the filling time, so as not to be controlled by time, for example, the injection time, whether it is 4 seconds or seconds, the filling time is about 1 second.6. in this way, the filling time and the holding time can be set up. The average injection time is 0.5 seconds longer than the filling time, and the other can be used as the holding and filling time.
