Electroforming metal mold: a metal mold made using electroforming technology that can act as a template for polymer or glass chips. The mold line width is controlled above 20 m and height above 5 m. The die cost is low, the life is more than hundreds of times, can meet the requirements of pilot stage.
The cost of micromachining has become a major factor limiting the industrialization of microfluidic chips. Injection molding will be the best way to solve this problem. Domestic traditional mould processing technology mainly focuses on the mould structure of more than 100 m with large error. The metal mould developed by Wen Hao independently is expected to solve the cost bottleneck of industrialization of microfluidic chip. The metal mold can be used to process material chips such as PMMA/PDMS/ glass. The results are as follows:
The picture shows PDMS chip and PMMA chip products processed by metal chip template
Ii. Advantages of metal mould/micro-electroforming mould
PMMA/PDMS/ glass chip can be copied many times
Good surface structure
Three, processing specifications
The processing line width of the metal chip template shall not be less than 30um, and the processing height shall not exceed 70um.
Microdie is a special material mold with micron pattern structure, which is a necessary product for the manufacture of microfluidic chip and other biochips. Microdie based lithography processing technology, according to the difference in the forming process and application range, we provide hard chip die products.
