Injection molding machine filter elements 680064, 5021687 and 709053 are filtration equipment specially designed for the hydraulic oil system of injection molding machines. The main function of these filter elements is to continuously filter contaminants such as impurities and moisture in the oil to ensure the normal operation of the injection molding machine system. They are widely used in many industries, including power plants, steel plants, shield tunneling, mining, papermaking, petroleum, shipbuilding, chemicals, textiles, and various power machinery.

 

The filter material of the filter element can be glass fiber, filter paper, metal mesh, metal powder, metal sintered or sintered felt, etc., with different filtration accuracy. For example, the filtration precision range of glass fiber filter material is 1-70 microns, the metal mesh filter material is 3-400 microns, and the filter paper filter material is 5-40 microns. These filters are rated for flow rates from 6 to 9100 liters per minute, operating pressures up to 450 kg and operating temperatures from -30 to 120 degrees Celsius.

The testing standards of filter elements follow a number of ISO standards, including but not limited to ISO 2941 (Test method for filter element rupture resistance), ISO 2942 (Test method for structural integrity of hydraulic filter elements), ISO 2943 (Test method for compatibility of hydraulic filter element materials and liquids) ), ISO 3723 (filter element end-to-end compliance test), ISO 3724 (filter element fatigue characteristics determination), ISO 3968 (filter element pressure differential flow characteristics), ISO 4572 (multi-pass method for determining filtration characteristics of filter elements) and ISO 16889 (filtration ratio /dirt holding capacity).
