This paper presents a development of an electric hole cutter for agricultural polyethylen film. Mechanical hole cutter with blades and electrical hole cutters are being tried in products now. But Mechanical hole cutter systems have a few faults. So the hole cutter systems using electrical heater have mainly been developed and optimized. Computer aided engineering was introduced for the purpose of electric heated hole cutter being developed, because it helped reduce the unnecessary tests. Three types of heated cups were surveyed with MSC/Nastran, and the type of model C was most effective in heat transfer.
