Oil Cooler Selection for Hydraulic System of Plastic Injection Moulding Machine: A Review
Abstract: The effect of oil temperature of the hydraulic system for Plastic Injection Moulding Machine is studied in this paper. Traditionally in India the hydraulic oil VG-68 for Plastic Injection Moulding Machine is used, which has an optimum temperature range with desired effective viscosity property is between 40C to 50C. The oil temperature goes high up to 55c and even higher than that during summer, which is not desirable for the machine operations. It is found that the operation of the machine will get sluggish as the oil viscosity get decreases. This is due to continuous flow and heavy production schedule. The oil needs to be cooled down as fast as possible from the elevated temperature to required temperature. So it is very important to choose the correct type and size of oil cooler for hydraulic system.
