Five years later, the editorial department of China Die Casting magazine came to Foshan Liansheng Die Casting Technology Co., Ltd. again. After five years of development and precipitation, Liansheng Company has achieved tremendous improvement and change, and the team is in good order and completely new. In the company's office building, the reporter and the company's leaders had in-depth exchanges on the situation and future development plans of Liansheng. Now, the visit and exchange contents of Liansheng are introduced as follows:

1、 Company Profile

Founded in 2005, Liansheng Company is located in Shunde District, Foshan City, an important manufacturing town in the Pearl River Delta. Covering an area of about 100000 square meters, it is a national high-tech enterprise specializing in the production of high-performance aluminum magnesium alloy die-casting machines and precision computer-controlled injection molding machines. Focusing on the R&D and manufacturing of high-speed, stable, precise and energy-saving die-casting molding equipment, we have successfully developed and produced LS200-LS5000 large, medium and small cold chamber die-casting machines to provide customers with more competitive products and solutions.

2、 Team strength

The company integrates R&D design, production and manufacturing, and sales services. With abundant capital and technical strength two hundred A professional R&D team of more than people, including middle and senior technical engineers eighty More than ten people, key personnel (design, manufacturing, assembly, commissioning, inspection and service of die-casting machine) have at least ten years of work experience in the industry.

The team is experienced and has participated in American GM GM Die-casting island 3000U And has undertaken major domestic die-casting projects such as Guangzhou Honda, Great Wall Motors, Toyota Aixin, Guangdong Hongtu, FAW United, Dongfeng Second Automobile, Shaanxi Fast, etc. These die-casting projects represent the most advanced technical force in the domestic die-casting industry;

    The die-casting equipment has obtained a number of technical patents, such as efficient pressure building device of die-casting machine, injection pressurization speed increasing mechanism of die-casting machine, short circuit detection protection device of die-casting machine, etc;

3、 Processing strength

     Production and processing workshops with international management mode, advanced large-scale processing equipment (floor boring machines, gantry milling machines, horizontal machining centers, pentahedral machining centers, CNC lathes, etc.) Precision testing equipment (CMM, Swiss Sensormate mold locking force measurement system, insulation resistance meter, grounding resistance meter, thermocouple calibrator, infrared thermometer, pressure gauge calibrator, vibrometer, coating thickness meter, Leeb hardness meter, Rockwell hardness meter, digital power parameter meter, etc.) and large-scale spare parts warehouse, All spare parts are bar coded and scanned for warehousing and ex warehouse, which greatly improves the use and management efficiency of spare parts. The current production capacity exceeds 1000 sets. The picture is as follows:

4、 Corporate development vision planning

Liansheng focuses on the fine design of die-casting equipment and sophisticated technology. Through continuous technological innovation, it improves the stability and operating efficiency of the equipment; Liansheng regards quality as the life of the enterprise. Through a perfect quality control system, it strictly ensures that parts with problems are not assembled and equipment with problems are not delivered; Liansheng provides customers with quality services, Solve problems for customers and spare no effort to ensure normal production of customers. The development vision of Liansheng is: In the short term, we will be among the top three in China and create a first-class brand in the industry.

（1） Technological innovation

① Injection system: adopt the design of larger accumulator capacity to strengthen the injection performance of the system and reduce the pressure drop of the system; Equipped with larger injection system tubing, it has stronger flow capacity, fast response, and smaller pressure loss, resulting in less oil temperature rise and lower energy consumption; The roughened design of pull rod ensures rigidity and formwork parallelism, pressurization and injection level in the same direction, and improves the stability of injection system.

② Column frame system: the machine hinge adopts four hinge lug structure+widened hinge lug design, which makes the force on the moving plate more balanced during mold closing and effectively reduces the risk of flying materials; Extremely short clamping oil return path to minimize back pressure and improve system operation speed; The innovative integral box formwork, combined with the thickened formwork design, can effectively improve the strength of the formwork and extend the service life of the formwork; Extending the length of the middle plate guide section (patented technology) can effectively improve the stability of mold closing; The patented large bar thread of the die-casting machine has a dust-proof and waterproof structure, which improves the stability and service life of the column frame operation;  

③ Rack system: the rack adopts annealing process + Double reinforcement balanced structure, reasonable stress of frame, more stable and reliable; The original three box oil tank separates the return oil from the inlet oil. The oil flow is reasonable, and the stability of oil circuit control is improved;

④ Hydraulic system: LS Series models are more integrated, with fewer pipelines, reducing the probability of oil leakage, and improving the operating rate of the machine; The pipeline adopts a large number of hose designs, which can effectively absorb vibration and reduce machine failure rate;

（2） Quality control

Adhering to the principle that quality is the foundation of enterprise survival and development, Liansheng is committed to providing customers with high-quality and reliable products. Quality first is not only our own requirements, but also our commitment to customers. Liansheng strictly controls the quality in strict accordance with the requirements of the quality management system, and is equipped with precise inspection equipment, which provides a strong guarantee for the quality of spare parts and the performance of the whole machine. The products have passed the CE and ISO9001-2015 quality system certification.

（3） High quality service

Provide free integrated solutions and services, which can be divided into three stages: pre-sales, sales and after-sales. The service covers: investment budget, plant planning, machine selection, installation and commissioning, personnel training, product process optimization, spot inspection services, after-sales on-site services, etc. Liansheng has set up 23 offices in China, at the same time, it has set up a number of sales and service outlets overseas, and set up a 24-hour after-sales service hotline. A specially assigned person is responsible for assigning the after-sales service personnel closest to the customer, rushing to the site in the shortest time, solving problems for customers, and fully ensuring the normal production of customers. Through unremitting efforts, Liansheng has been unanimously recognized by customers.

5、 Overview

    At present, through unremitting efforts, Liansheng has made a major breakthrough in the magnesium and aluminum alloy industries, and has received strong support from many industry customers. For example, customers of Wenda Magnesium continued to purchase machines and successively purchased 25 sets of our LS300-LS2500 cold chamber die-casting machines; At the same time, Liansheng has helped the development of the magnesium alloy industry and won the recognition of customers in the magnesium alloy industry, such as Dongguan Hemei, Shenmu Dongfeng, Taiyuan Jingcheng Magnesium, Wenda Magnesium and other customers who bought our cold chamber (magnesium alloy) die-casting machine;

Here, I would like to thank the leaders and colleagues of the die-casting industry for their support ， Liansheng will continue to work hard to improve the industrial technical strength, intensive cultivation, perseverance, return to customers and society.
