Q: How will the clamping force and injection pressure of injection mould be set?: The clamping force is usually formulated according to the projection area of the product, and there is an estimate of the clamping force in the die design to select the model of the injection machine. Injection pressure is generally obtained from the die flow analysis, but the flow analysis is not very accurate. In general, the injection pressure of PP products is 50-70, and the injection molding is a little higher (plastic with poor flowability, such as POM, PA, etc.). Injection pressure is based on actual production experience

Q: How to reset the EM-120 origin of the injection machine?: Two 、 brief introduction of injection molding machine:Injection molding machine, also known as injection molding machine or injection machine. It is a thermoplastic or thermosetting plastic plastic molding mold made of plastic products of all shapes of the main molding equipment. 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.This answer is classified by the scientific education, Zhen Zhen afterwards recommended

Q: Not computer, there is a proportional current. The whole machine has no hydraulic operation and the pressure gauge is zero.: Oil pump is good, the current output is good, that is, no pressure, it must be converted from electrical signals to hydraulic parts of the action of the middle course of disconnection, or the overflow valve spool stuck, or the pilot valve of the electromagnetic iron ring broken

Q: material delivery and storage slow, and other normal. TwentyReplace the proportional valve, cleaning materials and material storage direction valve, replaced the storage cylinder sealing ring. The problem still can not be solved: First exclude circuit problems, measuring the proportion of valve current, the big plate is damaged

Q: when the material stored, the screw has been in situ, and will not go back to the set stop position. What shall I do?: You can't go to the set position! Check whether the screw is worn or not. And then there is too much additive added to the raw material. Then see if it's not laid.

Q: The outer ring of the injection machine is against the ring. Do you blame the anti ring?It was normal to play PBT before. Now the storage stroke is 10 centimeters long or unstable: First of all, it is necessary to judge whether the extension of the check ring is badly worn. First, reduce the nozzle temperature, no discharge (other section set normal temperature). Then store the material, reduce the injection pressure, and inject the material to see if the material is moving forward. If the screw is not in the state of the discharge, the screw forward, it shows that the return to wear, the faster the speed, indicating that the wear is about serious

Q: What are the equipments around the injection molding machine?: Under normal circumstances, the main crusher, mixer, cooling tower, dryerCan match the mold temperature machine, chiller, suction machine and so on

Q: How many grams of 200t injection molding machine?: Heating part energy saving: heating part energy saving, mostly using electromagnetic heater energy saving, energy saving rate is about 30%-70% of old resistance ring.1. compared with the resistance heating, the electromagnetic heater has a layer of thermal insulation layer, and the heat energy utilization rate is increased.2. compared with the resistance heating, the electromagnetic heater acts directly on the tube heating, reducing the heat transfer and thermal energy loss.
