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.
When the material storage, you look at the nozzle has no material, if there is no transfer under the pressure, if you look at the material hopper have feed tube material, if there are very thick material in the hopper below the card down to the tube without glue, will have to screw in the back. Not always
The storage pressure is too small2. back pressure is too large, leading to the screw can not relax3. hydraulic system pressure relief4. melt temperature is too low5., melt motor power is too small, or the motor pressure is serious.6. screw barrel and raw materials do not match7., the material is not normal?More injection molding machine screw knowledge inquiries, Baidu search: "Jin Xin * screw", "Shenzhen Jin Xin * screw" for you to answer! Hope to adopt!
There are several situations may lead screw rebate: 1, no material or hopper outlet plug; 2, the back pressure is too large, resulting in melt coming from the nozzle; 3, material additives or mineral oil too much, causing the screw slipping; 4, the screw is not smooth, with melt wrap screw, cannot be dissolved in your current temperature; 5, machine maintenance, reverse screw; and I hope to help you.
