Micro Research Group

The trend of precise and diverse fins has resulted in thinned-drawn fin, arc fin, ellipse tube fin, flat tube fin, etc. The technical innovations of thin material forming, small hole drawing, higher burring, multi-diameter combination, and the implementation of 400~800spm punching rate and smart automation have raised higher challenge towards the fin die's parameters of heat exchaning technology, accuracy  and stability. Such a seemingly easy innovation requires the most complicated technology to guarantee precision.  Wuxi Micro Research can provide customers with one-stop service including products designing, die manufacturing, assembling, test running and mass production. As for heat exchanging fin patterns, we can achieve diversified fins with holes diameter ranging from 4.0mm to 25.0mm .

Since its establishment, the company has developed dies involved in all sectors of national economy, and maturely mastered the core technology of automotive safety parts dies, drawing dies, computer keyboard dies and other moulds and dies.

Miniaturization, high density and high transmission speed are technology development direction of connector. To break through technology bottleneck of small interval micro connector and high-speed transmission connector is the challenge and technical requirement of connector die enterprises. Wuxi Micro Research developed step 1.5 third-generation backplate connector and step 1.4 fourth-generation backplate connector die, achieving the technological innovation of data transmission speed from 10M to 10G. Meanwhile, our company successfully developed submodule structure die form to cater to the requirement of lower product cost, achieving rapid die adjustment during production and improving stamping production efficiency.

Recently, manufacturers have produced very small resin particles with a diameter of the order of micron. Therefore, very careful attention must be paid to avoid minute inaccuracies and resin leaks (burrs) when assembling dies.
Furthermore, mass production is a prime requirement, demanding us to manufacture parts with extremely high precision. Under these strict conditions, we will start mass production only after functional testing by test molds.

Press cutting dies always accompany a problem of "burrs" both at present and in the past. Ironically, dies need to maintain their sharpness to minimize the formation of burrs. Recently, as smaller and more high-precision products have been introduced to the markets, the parts for Kensaku Warigata (grinded split molds) need much higher precision than before.
To minimize the amount of burrs and extend the service life of dies, we face many challenges such as the form of a die. However, the most important points are to maintain a proper clearance between the punch and the die as well as to provide easy replacement of existing parts with spare ones.
