Meiki – Large Tonnage Direct Press Electric Injection Moulding Machine

Large Tonnage

Three models are launched as Mu series ranging from 650ton to 1,300 ton, which is well-balanced in all respects.

  • Adopton of a center pressing mechanism has generated even and powerful clamping force and made stable molding realised.
  • Suitable for products with thin-wall and complex dimensions by adopting direct-linked design for injection and mold open-close.
  • Compared with the conventional machine, 60% of energy consumption can be saved, 37% of dry cycle time can be eliminated and 7% of floor projected area can be reduced.
■Center Press clamping structure
A center pressing design has been adopted for the clamping structure.
There is no influence from bending movable platen.
There is no wearance problem associated with wearance from toggle links due to this machine
adopts a direct pressing type clamping unit.
The platens are also designed to absorb effects of heat expansion from the mold so that
a stable clamping pressure can always be applied.
This design will help to prevent broken gas vents within the mold due to excess clamping force
and prevent gas burn marks and short shots on the product.
The clamping force is evenly distributed helping to prevent flashes on the product.
This machine can provide precise mold protection and mold movement controls.
Furthermore, in both vertical and horizontal directions, long pitch ejecting is possible.
When mold opening, the center of the platen is pulled thus producing a stable and
strong mold opening force.
■Space saving design
The main ram is designed with a mechanical lock structure to
minimize overall machine length.
Floor projected area reduced by about 7% (Compared to our MC series machine)
■Power-saving design
By combination of center-lock type electric hybrid clamping unit and direct drive electric
injection unit,we have achieved a power use reduction rate by 60% compared to our conventional
hydraulic machine.
