Cast static pressure line
The static pressure line started trial operation in March 2022, and now it has officially started mass production. The line has high production efficiency, stable product quality, all performance indicators have reached the international leading level, automation operation has been realized, per capita output has been improved, and product quality has been recognized by customers. Sand box size of casting static pressure line is 1200 X850X350 (upper box)/350mm (lower box). It is suitable for high-precision castings with complex shapes, and can meet the requirements of cars, commercial vehicles, commercial compressors, hydraulic machinery, construction machinery, high-speed rail, and other industries.
The cast static pressure line has the following advantages:
1. High production efficiency with a speed of one hundred boxes per hour. Automatic casting equipment and robots are used, which can avoid human operation errors, reduce waiting time, improve production efficiency and output.
2. Good product quality. High precision and stable casting equipment and a control system is adopted. Precise control and management can be achieved through technical means for reduction of the rejection rate.
3. Reasonable production cost. Liancheng Precision can reduce production costs and improve the competitiveness by optimizing production processes, reducing labor costs and energy consumption.
4. Good working environment. The adoption of advanced dust removal, ventilation, noise reduction and other equipment can improve the workshop environment, reduce noise, dust, and other hazards.
5. High space utilization. By optimizing the process flow, the floor space is greatly rationalized.
The casting static pressure line adopts the well-known brand of sand treatment system, molten iron automatic transfer system, automatic pouring system and smelting electric furnace. The data interaction between devices is realized through the advanced communication system. By introducing intelligent equipment and systems, the automation of production process can be realized, and the production efficiency and product quality stability can be improved.
In order to meet the testing requirements of different cast irons, the casting static pressure line is equipped with advanced test equipment and instruments, including independent cast iron material testing laboratory, direct-reading spectrum analyzer, salt spray testing machine, electro-hydraulic servo universal testing machine, hardness machine, metallographic microscope, etc.
The medium frequency electric furnace is equipped with a flow monitoring system, which can monitor the cooling condition of the furnace body. A waste heat recovery device is provided for heating the workshop in winter.
Through the advanced automatic transfer system of molten iron, the electric furnace and pouring links are opened, clean production is ensured. The system also automatically weighs the weight of molten iron and gives early warning, which improves the weight accuracy of tapping. The automatic molten iron handling system can also ensure the safety of workers on site and improve the working environment of workers.
Liancheng Precision updates the cast iron process and equipment, and two specialized (gray iron) casting lines was put into operation on November 9, 2023. The two casting lines are composed of molding line of famous brand, electric furnace, sand mixer, sand treatment machine, equipped with cold core machine, hot core machine, molten iron transfer, automatic pouring, on-line inspection, independent laboratory, crawler shot blasting machine, lifting shot blasting machine, dust removal device and other complete sets of equipment. The size of the sand box is 700 X 600x250 X 250mm, the molding speed is 180-200 boxes/hour, and the annual output is more than 20,000 tons. The two casting lines specialize in the production of rotary parts, such as scroll body (moving scroll, static scroll), hydraulic parts, brackets, water pump shells, brake cylinders, cylinder heads, bearing seats and so on.
The official opening of the line indicates that Liancheng Precision can customize its production according to the requirements of customers. At the same time, the lines are of great significance for improving the quality of castings, improving efficiency, and reducing costs, and improving the market competitiveness of enterprises. Liancheng Precision puts forward the professional development strategy, devotes itself to the construction of professional (gray iron) casting lines, focusing on scroll, brake cylinder and other related products.
Liancheng Precision has taken advantage of the market downturn to fully expand its production capacity, seeks the opportunity to occupy the sufficient market share in the specialized domain.
