At the beginning of the 19th century, the printing industry rose, with which the type casting machine for type casting came into being. Soon, the hot chamber die-casting machine was born on the basis of the word casting machine. After the precipitation and development of technology, the hot chamber die-casting machine has become increasingly mature since the 20th century, so the cold chamber die-casting machine came out. At present, there are two types of die-casting machines for die-casting: hot chamber and cold chamber, which are divided into straight type and horizontal type. Die casting technology has developed for more than 150 years. Under the upsurge of scientific and technological innovation and 5G intelligence, die casting machines have been widely used in automation, flexibility, unit, large-scale and other aspects.
Liansheng Precision is a national high-tech enterprise specializing in the R&D and production of precision machinery and equipment. At present, the company is equipped with an integrated production line covering design, production, processing, assembly and testing equipment. Its products are mainly high-precision injection molding machines and high-performance aluminum magnesium alloy die-casting machines, Has been committed to providing customers with integrated molding production solutions.
Recently, Liansheng Precision introduced the advanced and mature design and manufacturing technology of high-end cold chamber die-casting equipment in Europe, sublimated on the basis of mainstream design technology at home and abroad, and fully understood the customer's use requirements, developed and launched LS series cold chamber die-casting machine. It has a stable and reliable high-performance injection system, a powerful and efficient mold locking system, a fully functional control system and an excellent real-time control system. Once launched, it has won the favor of the market.
Stable and reliable high-performance injection system
The new generation cold chamber die-casting machine of Liansheng Precision adopts the world's top brand hydraulic components such as Rexroth, Tokyoku, Youyan, and is equipped with high-performance, low-noise oil pumps to ensure the stability of pressure and flow; In addition, high precision electric proportional valve is used to realize screen setting for fast injection and boost pressure and flow, making it more convenient to adjust, high stability and easy to store; The non-contact displacement can make the speed conversion displacement more accurate and more repeatable.
In addition, the stability and efficient production of the die-casting machine are also the focus of the majority of manufacturing enterprises, and Liansheng Precision just knows this demand. Its die-casting machine accumulator has a large volume, rapid pressure building, fast pressure building, small pressure drop, sufficient energy, and the pressure and speed of the injection process are more stable and efficient.
Strong and efficient mode locking system
Considering the service life of the whole machine, Liansheng Precision Patent specially designs high tensile alloy steel guide posts. In addition, the thickening design of the overall box formwork can ensure that the equipment has high rigidity, high strength and high stability during high-speed operation, thus extending the service life; The design of machine hinge and template hinge lug is widened to make the force more uniform, which can reduce stress deformation and increase impact resistance. In terms of cost reduction and efficiency increase, the Liansheng precision cold chamber die-casting machine adopts a larger mold holding space design, which has a larger scope of application, can reduce the chance of flying materials, thus avoiding the waste of materials and saving certain production costs for enterprises.
Fully functional control system
The control system of Liansheng precision cold chamber die-casting machine adopts top well-known electrical control elements such as Siemens and Omron, and is equipped with European switching power supply. It has fast response speed, high control precision, strong anti-interference ability, stable operation in harsh environment, low maintenance rate and damage rate; In terms of energy conservation and environmental protection, Liansheng adopts high-performance servo control technology, which consumes less energy than ordinary models; In addition, the electric proportional control system has the functions of multi section pressure and speed control and low-voltage mold closing protection, which can make the equipment run more stably.
Excellent real-time control system
On the operating system, the Liansheng precision cold chamber die-casting machine adopts ten section injection speed setting, and can real-time feedback and control in a single injection. It is simple to operate, easy to set, and has a wide range of process parameters, which can meet the process requirements of various complex products; In the low speed section, the impact free start injection can be realized, and the injection hammer moves smoothly, which can minimize the involvement of air in the molten metal, thus improving the casting quality; In addition, Liansheng uses closed-loop feedback control to control the brake when filling is nearly completed, which is used to reduce flash problems and extend the service life of the mold; The real-time control system of Liansheng precision cold chamber die-casting machine effectively shortens the speed raising time with a servo valve with large flow and high response. On the basis of meeting customer needs, it not only ensures the appearance quality of the product, but also reduces the air content inside the product.
Die Casting Industry 4.0 Solution
In the era of intelligent automation, the word "efficient" has become the production standard pursued by enterprises. Liansheng Precision had an insight into this market demand years ago and successfully launched the solution of Die Casting Industry 4.0. It is a network control and transmission function specially developed for the die-casting machine, which can realize the information management of the entire die-casting workshop equipment and production process. After networking, the die-casting machine and die-casting production process can be controlled anytime and anywhere through smart phones or computers, so as to improve the level of die-casting production management and truly realize cost reduction and efficiency increase for enterprises.
As a benchmark enterprise in the die-casting machine industry, Liansheng Precision, since its inception, has always adhered to the guidance of high-quality equipment and services, and has always taken independent technological innovation as the cornerstone of enterprise development. While developing itself, it has led the industry forward, explored breakthrough innovation in die-casting technology, and helped the industry grow. It is believed that in the future, Liansheng Precision will expand the application field of cold chamber die-casting machine more widely with its cutting-edge technology R&D strength and continuous pioneering spirit, and boost the die-casting industry to forge ahead on the road of high-quality and high-level development.
