Detailed Specifications by Model
Expand a model to view the reference values for its injection unit, clamping unit, power and machine dimensions. Where multiple values are shown for injection performance, read them in screw-diameter order unless otherwise indicated.
The MH-45T, MH-60T and MH-85T sheets list two rows labelled “Clamping Stroke”. Both are reproduced as printed. Confirm the meaning of the second row and the required opening clearance for your selected configuration.

Selection Checklist for Mold Fit and Production
Platen size is the mounting surface dimension. Tie-bar spacing is the clearance between the columns. Maximum mold size is a separate model-sheet limit. Compare your mold length, width, thickness and mounting pattern with the platen drawing, then check the installation direction and the clearance needed for part removal.
Send your part drawing, insert drawing and mold dimensions when requesting a quotation. For a different mold-handling layout, see the vertical injection molding machine selection guide.
- Part and material: Provide the part and insert drawings, material grade, projected area and cavity count.
- Injection unit: Check the required shot, including runners, and confirm the screw and pressure for the chosen material.
- Production and shipping: Review loading, part removal and target output. Confirm packing dimensions and shipping weight for the quoted configuration.
For automated insert handling, see how a fully automatic vertical injection molding cell works.
