A Plastic Injection and Blow Moulding Industry was facing problems with an imported blow moulding machine. This was due to the contamination in the hydraulic 68 oil. After installing our EOP the problems faced by them magically disappeared. Also, it was found that earlier the machine's average output was 1200 pieces/hr but after the oil was purified using our EOP the same machine’s output shot upto 1550 pieces/hr.
