The present invention relates to the making process of microflow controlling polymer chip, and is especially the metal plate printing process of making microflow controlling polymer chip. The microflow controlling polymer chip is used for separating microflow of nucleic acid of different sized DNA segments, amino acid, protein, organic pollutant molecule, metal ion, inorganic anion, etc. Photoresist is painted to metal plate and metal negative is produced through exposure, development and etching. The metal negative is used in making microflow controlling polymer chip. Compared with available method, the present invention uses negative with the advantages of low cost, simple production process, high repeatability, hard material and long service life.
