Compared with the 315 ton model, the 630 ton press provides a larger 1200 × 1200 mm worktable and a 2200 mm open height, creating a substantially larger working envelope for larger tooling and more demanding forming applications. A 1400 mm main cylinder stroke provides substantial platen travel for tall tooling, while the 80 ton lower ejector cylinder with a 500 mm stroke provides powered part ejection where required. Powered by a 53 kW servo motor and a PLC control system with touchscreen on 380V power, this heavy duty closed frame press pairs servo-driven control with PLC recipe storage for repeatable mold programs in SMC molding and heavy metal forming.
630 Ton Closed Frame Hydraulic Press Key Features
With a 1200 × 1200 mm effective worktable area and a 2200 mm open height, this frame provides a substantial working envelope. This expanded envelope is suited to applications involving taller tooling, larger mold assemblies, or greater opening requirements.
The 80 ton lower ejector cylinder with a 500 mm stroke provides powered ejection for formed or molded parts that require active stripping from the die or mold. This feature is particularly useful for applications where manual removal or mold-side knockout is impractical.
The 1100 × 1100 mm slider bottom surface provides a large contact area for tooling installed on the 1200 × 1200 mm worktable. Actual mold mounting dimensions should be confirmed against the tooling drawings and press specifications.
This model uses a single 53 kW servo motor to provide the hydraulic drive power required for its 630 ton forming capacity and long-stroke operation.
For lower-tonnage SMC or BMC applications, a smaller closed frame model or a C Frame Hydraulic Press may provide a more compact and economical solution.
Model Comparison
Compared to the 315 ton closed frame model, the 630 ton closed frame hydraulic press steps up to a 1200 × 1200 mm worktable, a 2200 mm open height, and an added 80 ton lower ejector cylinder, sizing the frame for substantially larger or thicker composite and metal parts.

Engineering Insights and Buyer Considerations
If the tooling and process requirements fit within the 315 ton model’s working envelope, the smaller press may provide a more economical solution. When the application requires a larger worktable, greater open height, longer stroke, or powered lower ejection, the 630 ton model provides the additional capacity and working space.
If the forming or molding process ejects the part downward through the bolster rather than lifting it out from above, the 80 ton lower ejector cylinder provides dedicated hydraulic force for part ejection from below, eliminating the need for a separate knockout mechanism outside the press. If ejection is not part of the process, the lower cylinder remains unused, and a simpler frame configuration may be a more cost-effective match.

Control and Ejection Features
The standard 80 ton lower ejector cylinder utilizes a dedicated hydraulic circuit beneath the worktable for pushing the formed part free of the die after the main ram retracts, rather than relying on manual release.
The standard PLC touchscreen interface stores pressure, dwell time, and ejector timing together as a single mold program, so recalling a previous SMC or metal forming job restores the full cycle sequence.
The ejector sequence should be configured according to the hydraulic circuit and mold requirements to ensure safe and repeatable operation.
Frequently Asked Questions
630 ton vs 315 ton closed frame: which model fits large composite or metal parts better?
The 315 ton model provides a 700 × 800 mm effective worktable area with a 750 mm open height, while the 630 ton model steps up to a 1200 × 1200 mm table, 2200 mm open height, and adds an 80 ton lower ejector cylinder. Parts or molds that require this larger working envelope or powered ejection may be better suited to the 630 ton frame.
Can the 630 ton closed frame press handle molds approaching the full 1200 × 1200 mm worktable?
The 1100 × 1100 mm slider bottom surface provides a large contact area for tooling installed on the 1200 × 1200 mm worktable. Actual mold size and mounting arrangement should be confirmed against the tooling drawings and press specifications before ordering.
What does the 80 ton lower ejector cylinder add that the main ram alone does not provide?
The 80 ton lower ejector cylinder pushes a formed or molded part back up out of a deep die or mold cavity after the main ram retracts, which a press without a dedicated ejector relies on manual removal or a mold-side knockout to accomplish instead.
What should I confirm before ordering a 630 ton closed frame press with a lower ejector cylinder?
Confirm the mold or die footprint against the 1200 × 1200 mm worktable and 1100 × 1100 mm slider surface, check that the 2200 mm open height and 1400 mm stroke cover the tool height needed, and verify the ejector timing sequence in the PLC program before running production.
Why choose a closed frame over a four-column design for large SMC or metal forming molds?
A closed frame carries clamping load through a continuous stress loop, which keeps a 1200 × 1200 mm mold face square under off-center loading better than an open frame of similar tonnage. A Four Column Hydraulic Press offers easier side access for mold changes instead, so the choice depends on whether rigidity or access matters more for the specific mold.
Typical lead time is 45-60 days, depending on machine configuration and order requirements, backed by a 12-month warranty on core components. Confirming mold footprint, ejector requirements, and installed power before ordering avoids rework once a 630 ton closed frame hydraulic press is running production.
