Remarks:

  1. Injection pressure of J-ELIII series is different from that of JSW's hydraulic machines.
  2. "K K" size screw smaller than J200ELIII is same as "K K" size of one smaller model.
  3. Maximum injection pressure and maximum holding pressure may be restricted due to molding condition.
  4. The theoretical injection capacity is (cross sectional area of cylinder) X (stroke of screw.)
  5. The injection capacity is applicable for GP-PS and variable according to the grade of resin, molding conditions and mold.
  6. The Plasticizing rate is applicable for GP-PS.
  7. PC (polycarbonate), HPVC, other engineering plastic, etc., low temperature setting, and high speed molding, may require a high torque depending on the grade or molding conditions. Please contact us for more information.

Notes:

  • Actual figures of the specification will vary depending on final machine configuration. Please contact us if you require more specific data.
  • Performance specifications are based on theoretical data.
  • Due to continual improvements, specifications are subject to change without notice.
