Recently, Mr. Wang of Changsha encountered a trouble. Five injection molding machines in the factory broke down one after another within a month. The noise of the injection molding machine is increasing. The production is unstable. The injection pressure and clamping pressure can't be produced normally even if the parameters are the same. The senior machine adjusting technician, who was hired with a monthly salary of 15000 yuan, said that it's due to the quality of the injection molding machine was not good rather than his problem. However, Mr. Wang's injection molding machine has been used for more than five years. If the quality is not good, the problems should have appeared long time ago. Mr. Wang hopes that Taili Plastic Machinery could have an inspection in his factory. In fact, in Mr. Wang's case, we can be basically sure that impurities have entered the hydraulic oil pipeline, leading to pipeline blockage and resulting in unstable pressure, thus affecting the yield of products. Therefore, we directly opened the valve plate and filter element and had a check. It was indeed the problem of impurities.
We specially emphasized to Mr. Wang that the hydraulic system of the injection molding machine actually has two kinds of filter elements, namely, the oil filter element and the air filter element. The function of oil filter is to filter the impurities of hydraulic oil, and that of air filter is to prevent dust and isolate. In some factories, some operators didn't pay attention to the protection of the air filter element in face of the large dust, and even found some were directly placed in the open air during the on-site inspection. Due to the principle setting of the hydraulic injection molding machine, the hydraulic oil must be connected with the outside air, and the pressure difference is not allowed to be caused by sealing. Therefore, in the normal production process, the movement of the hydraulic oil leads to the frequent exchange of air. Therefore, the air filter element also needs to be replaced in the daily maintenance. Generally, the replacement frequency should not be too frequent, which can be controlled once a year to half a year. What should be remembered is the filter can't be directly connected with the outside world, which will make more impurities go in the hydraulic oil. Taili Plastic Machinery always keeps in mind that what a good injection molding machine factory should do is to help improving the capacity and boosting the profits, rather than offer the similar products the customers need. This is also what Taili Plastic Machinery keeps doing. Follow Taili Plastic Machinery and we will share more with you. |
