Pot 

POT/PLUNGER compresses the heating resin in packing process of semiconductors. It uses micro fine cemented carbide material and keeps the press intensity and internal abrasion.Besides it realizes 0.5um of inside diameter tolerance by micro-precise process and maximizes the durability as minimizing frictional resistance.All type POT/PLUNGER products including TOWA, YAMADA and FICO.
