Engineers with a passion for scientific research

(Baothanhhoa.vn) - Thanh Hoa province currently has 31 science and technology (S&T) enterprises, 1 branch of a S&T enterprise from another province, operating in many fields. These are pioneers in research and application, making S&T a driving force for the province's socio-economic development. From that environment, many engineers have emerged who are passionate about research, creating many valuable works and products, which have been applied in practice, affirming the role of the S&T intellectual team of Thanh Hoa.

From the provincial science and technology task, in 2015, engineer Nguyen Van Tu, Director of Anh Duong Advertising Company Limited, Hac Thanh Ward, successfully researched the manufacturing process of low-pressure dryers, automatic air convection. Anh Duong Advertising Company Limited has produced 2 types of low-pressure dryers, automatic air convection ADT9-2017 and ADT8-2017, which have been certified for intellectual property rights. This is a static dryer, horizontal tray, using 304 stainless steel trays to contain the drying products, a closed drying chamber and vacuumed to low pressure, with a drying temperature range of 30OC - 180OC. Therefore, it can be used to dry a variety of products, the biological properties, flavor, color, and shape of the product are retained at a high level, saving electricity, and is applied in medicine production, food processing, and forestry processing. This product also won the Thanh Hoa Provincial Science and Technology Award in 2023.

Mr. Dang Ngoc Tinh, Director of Dream F Vina Co., Ltd., Dong Tien Commune, said: Realizing that the low-pressure dryer with automatic air convection researched and manufactured by engineer Nguyen Van Tu has many advantages, since 2019 the company has cooperated with engineer Nguyen Van Tu to put it into production to serve the drying of forest products. The products after drying retain their natural color, are environmentally friendly, and are favored by many customers.

In addition to the project “Completing the technological process of manufacturing low-pressure dryers, automatic air circulation”, engineer Nguyen Van Tu also presided over the successful implementation of two provincial-level projects and was classified as excellent, which are “AD-BBB vacuum plate making machine” and “Metal engraving machine”. Not only that, he has successfully manufactured circuit printing machines, pulse engraving machines, gold processing machines, and toxic gas removal machines.

Engineer Nguyen Van Tu shared: “As a science and technology enterprise specializing in the production of handicrafts, gifts, stamps and metal engraving, to create quality, environmentally friendly products, there is no other way but to innovate technology and optimize products. Therefore, for nearly 30 years, I have constantly researched, innovated, and introduced new technology into production. In 2024, I was honored to be recognized by the Chairman of the Provincial People's Committee as one of the 10 outstanding science and technology intellectuals of the province. That is a great source of motivation for me to continue to strive to innovate and research to bring new technologies to serve production and life.

In 2012, after graduating from the Ho Chi Minh City University of Industry with a major in mechanical engineering, engineer Le Trac Dong worked at the Technical Department of Hong Duc Educational Equipment Joint Stock Company. Although only in his 30s, engineer Le Trac Dong, Deputy Director of the Production Factory of Hong Duc Educational Equipment Joint Stock Company, is the author of more than 50 initiatives and technical improvements applied in practice, contributing to improving productivity and product quality, saving billions of dong for the company. He is the youngest S&T intellectual in Thanh Hoa province to be honored in 2024 and won the 4th Nguyen Duc Canh Award - 2023 presented by the Vietnam General Confederation of Labor.

The initiative "Manufacturing an electrostatic painting robot" that he led is one of the typical initiatives, won the third prize of the 12th Provincial Science and Technology Innovation Contest and was awarded the Creative Labor Certificate by the Vietnam General Confederation of Labor. Sharing about this initiative, engineer Le Trac Dong said: Previously, the electrostatic painting department of Hong Duc Educational Equipment Joint Stock Company used over 100 tons of paint powder each year. The electrostatic painting process is through a closed chain. During the painting process in 2 booths, 3 workers had to use paint spray guns to spray additional paint powder on the products, increasing costs and causing many defects in the products. I and some colleagues in the company's Electromechanical Team researched the solution "Manufacturing an electrostatic painting robot" to replace humans in the painting process. Because the robot runs and sprays paint automatically with many gun heads attached to the robot arm, only 1 worker is needed to set the route and can fill the corners of the parts that the robot arm cannot spray. The electrostatic painting robot has contributed to reducing product defects, not causing pollution to the working environment, and each year brings the company over 300 million VND in profit.

In August 2025, he was awarded the Certificate of Creative Labor by the Vietnam General Confederation of Labor for the initiative "Manufacturing a natural wood splicing machine". The compact wood splicing machine fits the product details, is easy to use, can handle many sizes, and the materials are easy to replace when damaged, saving the company over 1 billion VND.

Deputy Director of Hong Duc Educational Equipment Joint Stock Company Vu ​​Ngoc Tuan said: "Le Trac Dong is a young engineer, passionate about research and technical innovation. He is a factor contributing to spreading the movement of promoting initiatives and technical innovation among the company's staff and workers."

The story of engineer Nguyen Van Tu and engineer Le Trac Dong is just 2 of many science and technology intellectuals in the province who are diligently researching and finding new solutions to apply in real life. They not only affirm their passion for creativity, but also contribute to spreading the movement of technological innovation, improving labor productivity, and building sustainable science and technology enterprises.
