A study to develop microfluidics chip processing techniques and the associated manufacturing technologies, undertaken by the Dalian Polytechnical University, has accurately cloned microchannels and thermal bonding, using a range of numerical programmed approaches for temperature, pressure, and positioning control. The microfluidics chip, developed on the thermal press mechanism, has attracted numerous clients, including the Chinese Academy of Inspection and Quarantine, CapitalBio, Fudan University, Jilin University, Wuhan University, and Shenyang Pharmaceutical University. The newly developed chip also made successful applications in biochemical analysis.
Researchers also developed a boardless growing technique that fits the metallurgical thermal press mould. The mould made with the new technique is of numerous merits, including well-shaped vertical walls, highly polished surface, and long lifespan. It can be broadly used in thermal press and mould applications.
To make the technique available for mass production of diverse polymer materials, the research team also rolled out an RYJ-II thermal press shaper. With an indoor temperature at -300?? , a controllable pressure between 0-50 kN, and a valid thermal press area at 150X150 mm2, the device can have a detached control of its upper and lower press heads, with their relative positions being told by an optic ruler. The thermal press shaper can be used as a single unit, or incorporated into an automatic set equipment. The device has become a part of the automatic system for manufacturing polymer microfluidics chips. It also promises a fine application perspective for manufacturing plastic microfluidics chips. With an accurate temperature and pressure control mechanism, it promises for more applications in other scientific researches.
