HIGH SPEED & PRESSURE INJECTION / INJECTION COMPRESSION SYSTEM
High Speed & High Pressure Molding
Filling a thin wall section requires high speed and high pressure injection capabilities. Because thin wall sections are exposed closely to the mold cavity surface it drastically loses its molten material heat. These applications are perfect for our super high speed and high pressure injection capabilities.
A new hydraulic servo system control improves injection speed and injection pressure dropping response after V-P switchover.

-
5.9 ms (0.0059 sec) to reach 1416mm/sec (55.7”/sec)
-
6.2 ms (0.0062 sec) to reach 458 MPa (66,427 psi)
The injection compression clamping system helps reduce molding defects such as warpage, distortion and excessive shear. Injection compression molding also reduces its clamping force and cooling time.
We offer the most advanced injection compression system in the industry:
-
High speed / high response injection compression control
-
Maintains tight dynamic parallelism
-
Accurate alignment of mold open-close
