What are the hazards of excessively high temperature rise of injection molding machine?

2023-01-12

What are the hazards of excessively high temperature rise of injection molding machine? Today, Liansheng injection molding machine manufacturer shares with you that if the temperature rise of the injection molding machine is too high, the oil viscosity will be reduced, the leakage will increase, and the volumetric efficiency of the pump and the efficiency of the entire system will be significantly reduced. With the decrease of oil viscosity, the oil film of moving parts such as slide valve becomes thinner and cut off, and the friction resistance increases, leading to increased wear. This will shorten the service life of the machine. If the temperature rise of the injection molding machine is too high, the working quality of the parts will become worse, the air dissolved in the oil will overflow, causing cavitation, reducing the working performance of the hydraulic system, and reducing the working efficiency of the injection molding machine. Hydraulic system

How to solve the problem of oil leakage and heating of injection molding machine?

2022-12-24

The causes of oil leakage of injection molding machine can be divided into internal leakage and external leakage. Internal leakage refers to that a small amount of liquid inside the hydraulic components leaks from the high-pressure chamber to the low-pressure chamber. Adjust the hydraulic components of the injection molding machine to reduce the wear of the components to be controlled. It can also reduce and eliminate internal leakage through innovative maintenance design of hydraulic components. The causes of external leakage are roughly as follows: 1. If the pipe joint is loose or the ring is damaged, it should be handled by tightening the joint or replacing the ring. 2、 There is leakage on the joint surface of the component, which is mainly caused by insufficient pre tightening force of the fastening screw and wear of the joint ring. At this time, increase the preload or replace the ring. 3、 Because part

How to realize quick touch change of small injection molding machine?

2022-12-08

How to realize quick touch change of small injection molding machine? For the injection molding field, the theoretically achievable productivity is 95%. In fact, the productivity of some injection molding enterprises is far less than this level. One of the main reasons is that it takes a lot of precious time to replace the mold shell. Why can't "quick mold change" be accepted by small and medium-sized injection molding machine customers? In fact, the methods and facilities for rapid mold change have been used in the plastic machinery industry for 30 years. In a broad sense, the rapid mold change system software is specially used on plastic machines with heavy loads. However, for large, medium and small tonnage plastic machines, most of them still use the method of manual mold changing; As we all know, the tonnage of plastic machines

To provide solid support for the development of the manufacturing industry, Guangdong Liansheng has set an innovation benchmark for the industry!

2022-11-24

Manufacturing is the foundation of a country's development and the key link to ensure the normal operation of people's livelihood. No matter how the global economic situation develops, no matter how the international relations change, the manufacturing industry is always an important "foundation" for a country. Today, in the macro environment of the general downturn of the world economy, China's Ministry of Finance, the State Administration of Taxation, and other functional departments have introduced a number of tax reduction policies for the manufacturing industry. It provides more breathing opportunities for manufacturing enterprises to win more market development space. As one of the important leaders in the manufacturing industry, Guangdong Liansheng Precision Machinery Manufacturing Co., Ltd. was born in 2005

How to control the temperature of injection molding machine?

2022-11-15

How to control the temperature of injection molding machine? The thermocouple of the injection molding machine for precise temperature measurement is used as the temperature measuring element, and the millivoltmeter for accurate temperature measurement becomes the temperature control equipment of the injection molding machine; Selectively adjust the temperature of each section of the barrel and the mold temperature. The temperature that the injection molding machine must control during the injection molding process includes the barrel temperature, nozzle temperature and mold temperature. The first two temperatures seriously affect the plasticization and fluidity of plastics, and the last two temperatures seriously affect the fluidity and cooling of plastics. 1、 The selection of the barrel temperature of the injection molding machine is related to the characteristics of the plastic, and largely depends on the flow temperature (Tf) or melting temperature of the plastic

How to ensure the quality of plastic products of multi-color injection molding machine?

2022-11-09

How to ensure the quality of plastic products of multi-color injection molding machine? The so-called multi-color injection molding machine can process plastic products in many colors. Therefore, attention must be paid during the purchase process. The ultimate reliability is absolutely the best, so it needs to be selected according to the actual situation. The quality assurance that can be achieved in the end will be better, so the quality that it can bring will be better in the end. Therefore, the processing quality of plastic products starts from the performance of processing equipment. As a kind of injection molding machine, it can bring the best sense of quality and guarantee the best reliability. If you want to make the overall presentation better, you need to choose from a more professional perspective
