Breakthrough in key technologies Hua Wei want to enter the high-end hydraulic parts

As a specialized hydraulic parts factory engaged in the production of hydraulic pumps, valves and hydraulic systems of construction machinery in China, Shandong Huawei Hydraulic Manufacturing Co., Ltd. focused on R & D and lean production in the past two years and achieved remarkable results. In 2012, the company's annual inventory turnover days decreased from 120 days of the beginning of the year to 66 days in December. The inventory share of inventories decreased by 81% from the beginning of the year and product quality was improved by 70%.
"In 2012, we invested more than 20 million yuan in research and development, is now a small batch of trial production of 6 tons ~ 8 tons of excavator main control valve, and has been sent to Shandong Linong pilot installation, fully meet the requirements. Follow-up will gradually large tonnage Excavator hydraulic valve to start R & D and trial work. " Hua Wei Group Chairman Zhao Yibin told reporters.
Breakthroughs in key technologies breakthrough intelligent products come out <br> Over the years, the core components of high-end hydraulic engineering machinery parts has been monopolized by foreign companies, resulting in 70% of the industry profits have surrendered to others, as the industry's development " ".
In order to get out of this awkward situation, Hua Wei Hydraulic Parts Company devotes itself to researching and actively exploring in recent years and has successfully developed a series of energy-saving, environmental protection and intelligent products. Zhao Yibin introduced, "In 2011, the company combines the features of low speed large flow and high speed small flow in the product research and development with the turning of the original steering pump from single pump to double pump and increases the flow signal valve and flow rate through the design The conversion control valve realizes the control of two pumps' merging at the low speed and the control of the double pump at high speed, realizing the energy saving and consumption reduction. The hydraulic parts produced by the company have passed the test and the energy saving effect has reached 9% ~ 13%.
In addition, compared with the traditional noise of external gear pump gear hydraulics, the company in 2012 through the modification of the gear design to reduce the gear pump noise. Zhang Qiang, director of Hua Wei Hydraulic Company, admitted frankly that this series of products have been supplied in batches to Shandong Lingong and other enterprises and have been approved by users. According to some customers, after the installation of the product, the noise of the gear pump is reduced by 8 ~ 10 dB compared with the original design.
This reporter has learned that in 2009 the company has independently developed HV32.2 solid rod multi-valve, and made the product patent. In 2010, the company also developed the A306 electronically controlled shift valve on the basis of the VOLVO shift valve. At present, the product has passed the industrial test of Sweden VOLVO bench test. All the products are electronically controlled to make operation more convenient and more comfortable. The fatigue strength of the operator is reduced and the level of similar foreign products is reached.
According to the insiders, the successful development of hydraulic parts mainly used in construction machinery indicates that the development of hydraulic industry in China has entered the stage of introduction, digestion and absorption from the phase of surveying and mapping and imitation "follow suit", and started to grasp the core technologies and carry out autonomous Innovation stage forward.
The full implementation of lean management quality zero defect "In the hydraulic parts industry, companies do not pay attention to detail simply can not survive, the pursuit of lean production is zero defect, the problem is to solve the details," Zhang Qiang told reporters in the field of automobile production, Japan has been able to compete with Europe and the United States, officially benefiting from lean production methods.
Lean production is the second revolution after Ford invented the mass production mode of assembly line. It completely changed the pattern and production mode of the world auto industry and made Toyota Motor Company rise in the world.
In recent years, Hua Wei hydraulic introduction of lean production, this idea into the automotive industry outside the manufacturing sector, but also achieved remarkable results.
Practice has proved that the establishment of the company's lean production model has effectively raised production efficiency and product quality, reduced production costs and inventory, saved a lot of money and significantly improved the Company's core competitiveness.
"Compared with the domestic competitors, our gear pump is 5% lower than the price in the same industry. The quality feedback rate of various pump and valve products in the company is also below the industry standard of 10%." The company's technical director Xing Yongbin told reporters that the company since the implementation of lean management, customer orders as the starting point of pull-based production model has begun to take shape, small quantities and more varieties of product manufacturing processes to reduce the overall operating costs and increase the company Responsiveness to market conditions.
In order to produce high-quality products, to maximize the value of the product, all the products produced by Hua Wei Hydraulics are technically designed in accordance with the APQP process, and the process flow chart, FMEA, control plan, visualized operating documents and so on In particular, visual operating documents highlight the essentials of their actions. Xing Yongbin told reporters that, for example, screw the screw, the past used pneumatic screwdriver directly tighten, and now the first screw in place, then tighten the wrench to tighten, and tighten the logo. All these changes provide reliable quality assurance for the products produced by Huawei.
Confident of the future has been optimistic about the Chinese market, "We are now produced hydraulic parts are mainly supporting the valve and excavator pump valves and motors, the next few years, we will be based on loader hydraulic parts and gradually turn to provide excavation Hydraulic system supporting the main product of the transition, "Zhao Yi Bin said.
Zhao Yi Bin told reporters that at present, the group each year put 25% of sales revenue into research and development, and strive within five years, become the hydraulic industry leader.
"Our sales position is to provide hydraulic components for the entire domestic construction machinery market. By 2016, our sales target is 300 million yuan."
To achieve the strategic goal, Zhao Yi Bin seemed confident, he said, "Technically, we have experienced R & D team; from the management point of view, we have advanced lean manufacturing management concepts; from the market, we Has been generally recognized by customers, we are full of confidence in the domestic market. "
He also said that China's hydraulics industry is indeed a weakness compared with that of other countries. It started relatively late and there is hardly any major increase in the accumulation of some things if there is no quantity. However, he is convinced that after the joint efforts of industry associations and enterprises in recent years, it is entirely possible that the manufacturing level of hydraulic components in China will catch up with foreign-funded enterprises in the near future.
It is understood that Huawei Group Co., Ltd. is a diversified diversified group with a large number of companies including Huawei Heavy Industries, Huawei Technologies, Mengshan Machinery, North Valley Electric, Mountain Leasing, and Weisheng Advertising.
