CDROM metal stampings - stainless steel 0.15 mm thick. Carbide die was designed with 20 stations for use on 45T press at about 200 spm.

Our chief tool and die designer has been designing and manufacturing stamping tool and die in Singapore since 1987. Our CAD station uses ExcessPro which provides dxf and iges format files. A few examples of the parts for which we have designed the stamping dies are shown here. Click on the pictures for enlarged view.

Our Die Design Advantages:

Cut cost through incorporating secondary processes into the die - example is in die tapping using gewinde former. In-die tapping increases productivity and improves tapping quality, as it avoids the need for time-consuming, labour intensive secondary operations such as tapping and setting welded or crimped nuts.
Work with the product designer in product engineering of the part. Input this into the die design.
Design tool for automation line - we have done many such jobs for the semiconductor industry.
