Recently, Mr. Wang Guiqiu (“Mr. Wang”), Director of DEKUMA Rubber Machinery Business Division, was rated as a “senior engineer”.
Mr. Wang has been engaged in the rubber and plastic machinery industry for more than 20 years. Since he worked in Datong Group in 2000, he has been responsible for the overall development and design of the mechanical main body and hydraulic system of rubber injection machine. He has successively obtained more than 20 patented technologies and numerous R&D achievements, and has been silently contributing to the development of China’s rubber and plastic machinery industry.
During his professional career, Mr. Wang always led his team to challenge themselves and get involved in difficult projects, such as the R&D of automated rubber track machine in 2013.At that time, a leading company in the production of rubber tracks in China contacted DEKUMA team and described various difficulties of traditional rubber track machines such as “over-reliance on labor, extremely high labor intensity, and difficulty in recruiting and retaining staff”, in the hope that a set of automated production equipment can be customized by DEKUMAteam for them.After fully understanding the production process of tracks, Mr. Wang and his team proposed a variety of schemes for the process flow, and confirmed the specific direction with the customer. After months of intensive preparations and multiple rounds of adjustment, the experimental model was finally completed and a satisfactory automation scheme came out.Nowadays, the automated rubber track machine has been improved for several times, can realize automated rubber sheet loading, automated demolding and automated reclaiming as well as can produce “nodeless integrated track” that cannot be achieved manually, greatly improving the product quality.Since 2013, DEKUMA has supplied a total of nearly 300 sets of automated rubber track machines to more than ten leading enterprises in rubber track production both at home and abroad, and its products have been exported to South America, North America, Southeast Asia, South Korea, India and other countries and regions.In 2012, DEKUMA cooperated with the“national engineering research center of new polymer molding equipment“ of South China University of Technology, and successfully developed DKM-R series large-scale rubber injection machine, which won the second prize of Guangdong Province Science and Technology Progress Award and the first prize of Dongguan Science and Technology Progress Award; in 2017, the “rubber track vulcanization molding machine project” won the Award of Dongguan First Set of Key Technical Equipment…The above-mentioned are the achievements made by Mr. Wang and DEKUMA team after several years’ hard working. Mr. Wang himself also obtained 7 invention patents and 15 utility model patents in the R&D field of rubber injection machine.In addition, at the German K Show to be held in this October, DEKUMA will launch the latest DKM-RC series rubber injection machine for automobile rubber seal strip angle joint, which is also one of the ace products developed by the team led by Mr. Wang.Although the corner connection of automobile door and window seal strip has relatively simple structure, it is small in size, very complex in shape, low in load bearing and difficult to process. High-precision injection technology is required to ensure its quality. In the past, high-end users had no choice but to choose the imported equipment.The DKM-RC series automobile rubber seal strip angle splicer was jointly developed by DEKUMA and a well-known European rubber and plastic equipment brand. It combined advanced European technology and China’s efficient processing and production capacity, filling the blank of domestic technology in this field at that time. Its greatest advantage is its ultra-high injection repeatability precision, with the single injection volume of 1-5g and its precision of ±0.02g.After Mr. Wang’s continuous innovation and upgrading of DKM-RC series automobile rubber seal strip angle splicer, both the reliability and stability of the equipment are close to European equipment standards. In the past 18 years, more than 3,000 units of the equipment have been sold, and the products have been exported to Europe, America, South Korea and other regions. Henniges, DONGIL and Unihopper are our important strategic partners.With the joint efforts of Mr. Wang and the engineering team, DEKUMA has become the leader in China’s high-end rubber and plastic machinery industry, and has become the best choice to replace imported equipment.China’s manufacturing industry is in a critical period of transformation and upgrading, and high-end technical talents will play an increasingly critical role.DEKUMA, which has always been driven by innovation, not only has an experienced engineering team, but also continues to cultivate and introduce excellent technical talents. More “senior engineers” will emerge in the future. They will grow up together with DEKUMA, continue to innovate to achieve the goal of “replacing imports and replacing labor”, and contribute to the upgrading of China’s manufacturing industry.
At present, although the scale of China’s manufacturing industry ranks among the top in the world, with the gradual disappearance of the demographic dividend and the development of industrial upgrading and transformation, potential problems in the industry are gradually exposed.
Most of the traditional rubber and plastic machinery equipment is mainly low-end, and the automation level and performance of these equipment are still far behind foreign high-end equipment.
For example, traditional production equipment may cause environmental pollution and cause factories to be moved to remote areas. Machines with a low level of automation make workers too labor-intensive, resulting in the dilemma of finding and retaining people. Production equipment in some certain fields has long relied on imports. These are the “unspeakable pain” of the rapidly developing Chinese manufacturing industry!
Dekuma believes that relying on “two substitutions” and “technological innovation” can alleviate these pains. From the transformation and upgrading of equipment to promote the industrial upgrading of the rubber and plastics industry. Complete the transformation from “big” to “strong” and enhance the competitiveness of China’s manufacturing industry.
“Two substitutions” refers to the substitution of imported equipment and the substitution of labor. Only when China can independently develop and produce high-end equipment can we gradually reduce our dependence on imported equipment, and enable more domestic manufacturing companies to realize their original aspirations and help the rubber and plastics industry produce intelligent manufacturing.
“Innovation” is the difficulty of Chinese manufacturing and the pain of Chinese manufacturing, but it is also the light of hope and breakthrough of Chinese manufacturing. Since the reform and opening up, from Chinese manufacturing to Chinese “intelligent” manufacturing, only when manufacturing enterprises take innovation as the first driver can we drive China into an era of innovation in an all-round way.

#01 Finishing by bottom cylinder, improving product qualityGenerally, for the finishing of brake pad backing plate by traditional punching machine, it is necessary to install special hydraulic device.For the structural design of our brake pad backing plate hydraulic press, there is a dedicated bottom cylinder for the finishing process. And it has the dual-purpose function of front and back finishing.Our hydraulic system is equipped with a dedicated proportional pressure valve to adjust the floating blank holder force during finishing. This provides support by floating force.It will not affect the processed dimensions in the previous processes.Besides, the products produced by the brake pad backing plate hydraulic press can also meet the requirements of high-end brand auto parts.In order to make the brake pad backing plate hydraulic press suitable for products that require a large leveling force, we have also designed dedicated back-finishing mould supporter. So that the large main cylinder presses it to be flat, and the bottom cylinder conducts back finishing. This finishing process can greatly improve the surface quality of product,and increase the production efficiency.

Small floor space, facilitating the installation of automated devices Conventional small countertop hydraulic press has a headache, i.e. occupying a large floor space.Both the hydraulic system and the motor system are placed on ground. Therefore, there is little space for installing automated devices. It is much inconvenient for automated production.The less automation, the harder it is to recruit.DEKUMA team has found that, as long as the hydraulic and electrical systems are designed reasonably, and the brake pad backing plate hydraulic press adopts top-mounted layout, both the hydraulic system and the electric control system are placed above the machine body, the floor space will be smaller, and there are no obstacles around. Automated devices can be installed on site as required.Therefore, for DEKUMA hydraulic press,whether it is a single machine with automation or multi-machine linkage with automation,it will not be affected anymore.Our customers, after actual production on site,have fed back that because the labor intensity is reduced, and the space utilization is increased, both the production managers and the employees, like our brake pad backing plate hydraulic press very much. We are delighted to receive such a high praise.

Efficient production at a speed comparable to that of punching machineMany customers are worried about that using hydraulic press instead of punching machine may affect the production efficiency. The production speed of our brake pad backing plate hydraulic press is much faster than that of ordinary one.Our punching and nail pulling processes can be completed within 1.3-1.6s, and the finishing process can also be controlled within 1.7-2.3s, comparable to the production speed of traditional punching machine. If it is equipped with automated linkage production, it can even reach 13-15 pieces/min.Some people will ask whether the oil temperature will be too high after the hydraulic press operates for a long time, and whether stuck valve will be caused.Don’t worry, our specially designed hydraulic system is equipped with a two-way cartridge valve.Its maximum diameter can reach 25, which can reduce the resistance of hydraulic oil when flowing at high speed.Large diameter means less heat generated by extrusion. Coupled with a suitable oil cooler, it can also ensure the temperature of the hydraulic system, making the hydraulic press faster and quieter in production, and meeting the needs of 24-hour stable production.Customers and friends who are still using punching machine may try to use Datong servo hydraulic press.
