As electronic devices become increasingly smaller and higher functionality, the precision processing technology required for electronic components is becoming an increasingly important factor in advanced technology industries.

In particular, the high-density integration of semiconductors and the expansion of small electronic devices such as mobile gadget have increased the demand for high-precision and high-density packaging of components.

In order to meet these needs, Maxell's precision electroforming technology EF2 (official name: Electro Fine Forming) is used to form patterns on SUS plates and Si wafers to provide precision electroformed parts in various shapes. Multi-layer electroforming technology enables us to produce a wide range of high precision parts such as nozzles and filters for inkjet printers, molds for electronic parts, micro gears, micro washers and structural parts for micro machines.
