The promoter of domestic 3D special printing technology
Xiong Changyou Deputy Chief Technician of Offset Printing Workshop Sichuan Yibin Push Group 3D Co., Ltd.
Xiong Changyou, born in March 1979, a member of the Communist Party of China, college degree, lithographic printing technician (second level), worked in Sichuan Yibin Push Group 3D Co., Ltd., is currently the deputy chief technician of the offset printing workshop, a person who grew up from a 3D printing position Of technical experts. Mainly engaged in the application and research of 3D grating material lithographic printing process, and made important contributions to the company's realization of Wuliangchun, Wuliangol and other upgraded 3D packaging. He has carried out a number of company scientific and technological innovation projects, annual project quality improvement projects, QC projects and other activities, all of which have achieved impressive results and created benefits for the company. He has won numerous honors from industry authorities, provinces, cities and group companies.
Ingenuity is the persistence of ten years of sharpening a sword
His technical innovations, "A kind of hook-bottom gift box" utility model patent technology, "A double-opening packaging box", "A grating structure and packaging box used to improve the forming effect of the bronzing process", respectively obtained the national real new patent technology .
Because of his outstanding performance and superb skills, he has been rated as an advanced individual by the company many times. Won multiple awards in the industry skill competition: the first prize in the preliminary and semi-finals of the 3rd National Printing Industry Vocational Skills Competition (Sichuan Division), and the third prize in the 3rd National Printing Industry Vocational Skills Competition (Finals) prize.
Won the "Technical Expert in Sichuan Printing Industry", "Technical Expert in Sichuan Province", the first "Yibin Youth May 4th Medal", the sixth "Yibin City Technician with Outstanding Contributions", and the group company "Wuliangye Youth Star" etc. .
Innovation requires the spirit of overcoming difficulties
He has the courage to explore and innovate constantly. The lenticular products need high-precision dot printing (amplitude modulation dot 700LPI) to achieve high-precision restoration of 3D three-dimensional patterns. The amplitude-modulated nets require a certain arrangement angle. Due to the magnification and refraction of the grating lenticular lens, moire is prone to appear in some net adjustments, which makes the pattern image rough and affects the aesthetics. Therefore, he proposed to introduce 10μm frequency modulation network technology for testing, and after repeated demonstrations from the water, ink, blanket and other auxiliary materials and the state of machinery and equipment, the frequency modulation network points can be restored with high fidelity.
The final application of 10μm frequency modulation network technology restores the three-dimensional printing pattern of the grating, so that the fineness of the product pattern is qualitatively improved, and the 3D effect is highly recognized by customers at home and abroad.
products are exported to the United Kingdom, the United States, New Zealand, Brazil, Japan, India and other international brands of gift cards, electronic product packaging, animation, perfume boxes and other products, with a total output value of more than 46 million yuan. It provides technical support for the company's development as the world's 3D printing base and leading 3D enterprises.
In order to actively respond to the "green printing" and "environmental low-carbon" advocated by the country, and reduce VOCs emission requirements. Through many technical investigations and feasibility analysis, he actively communicated with technical experts and consumable manufacturers in the industry, and formulated a detailed implementation plan based on the current status of printing materials in the workshop, in terms of water hardness, substrate characteristics, ink printing suitability, etc. Based on comprehensive considerations, it is proposed to use alcohol-free fountain solution instead of traditional fountain solution.
After more than one month of close follow-up testing and adjustment of two printing machines, we finally found a stable state of alcohol-free fountain solution to achieve ink balance, successfully achieved a technological breakthrough, and promoted all machines to use alcohol-free process production. After improving the process, the on-site environment of the production workshop was improved, and it also made a positive contribution to the company's emission reduction and consumption reduction.
In response to the extremely high overprinting requirements of 155-line and 161-line contour grating materials, he actively led the team to carry out technical research, explored the law of overprinting changes in 3D printing, through the pretreatment of the printing material, selective partial adjustment of pre-press documents, etc. The method makes the product overprinting strive for perfection, which greatly improves the product quality.
Since the transparent PET film is foggy after varnishing and the product transparency is poor, he proposed to use a combination of PS plate and flexographic plate on the offset printing machine, and use small-format flexographic plate to flexibly paste, instead of traditional blanket coating and glazing. . Successfully realized the high-transmittance glazing process of PET transparent film, improved the transparency of the scratch-resistant layer on the transparent packaging surface, and achieved stable mass production.
There are many and many similar improvements. As long as the products that require process optimization and innovation, he is a technical pioneer. He organizes team research and analysis in the first time, discusses countermeasures and improvement plans, and solves all problems.
In 2014, Xiong Changyou obtained the qualification of an examiner for print finishing work of the Vocational Skills Appraisal Center of the Sichuan Provincial Department of Human Resources and Social Security; in 2020, he obtained the qualification of a digital printer for the Vocational Skills Appraisal Center of the Ministry of Labor and Social Security.
