An oil filter is a filter to remove contaminants from engine oil, transmission oil, lubricating oil, or hydraulic oil. Oil filters are used in many different types of hydraulic machinery. A chief use of the oil filter is in internal-combustion engines in on- and off-road motor vehicles, light aircraft, and various naval vessels. Other vehicle hydraulic systems, such as those in automatic transmissions and power steering, are often equipped with an oil filter. Gas turbine engines, such as those on jet aircraft, require the use of oil filters. And oil production, transport, and recycling facilities employ filters.

Parts of the hydraulic oil filter in our project are piston housing, shaft housing, top plate, crankshaft, and piston.

The aim of the paper is to model and design casting tool for piston housing which is used in a hydraulic oil filter having pressure 50kg/cm². In casting tool, we are designing core cavity, mould base plates. Calculations are to be done for cavity fill time, cavity fill rate, gate area, runner area, shot weight, Die Cooling Calculations. CNC programming for core and cavity is to be done and for remaining manufacturing processes are to be done.

Modeling and Casting Tool Design and CNC program generation is done in 3D parametric software Pro/Engineer.
