TRIMMING PRESS
Efficiency, Edge Quality, and The Removal of Secondary Operations
Press for Die Casting, Forging & Plastics
High-Precision Edge Finishing and Flash Removal
Precision trimming is a critical final stage in the production of die-cast and forged components. Our hydraulic and servo-mechanical trimming presses are engineered to remove flash, runners, and overflows with high repeatability, ensuring clean edges and protecting your secondary tooling from premature wear.
At MetalPress Machinery, we provide heavy-duty hydraulic and servo-hydraulic trimming solutions engineered for high-duty cycles and the clean shearing of aluminum, zinc, magnesium, and advanced composites.

Choosing the Right Press Configuration & Press Frame
We offer different types of trimming presses, die casting presses, forging presses, and plastics presses among which the most versatile press types are as follows.
The Industry Standard: Hydraulic Trim Press
The Trim Press is our specialized solution for the die-casting industry. Designed with high-speed approach and retract cycles, it is optimized for the rapid removal of flash from aluminum and zinc castings. Its open design allows for easy integration with robotic pick-and-place systems.
High-Stability Trimming: 4-Post Hydraulic Press
For larger forgings or multi-cavity trim dies, the 4 Post Hydraulic Press offers superior structural stability. The four-post design ensures that the upper platen remains perfectly parallel to the die, extending tool life and ensuring a consistent shear across the entire perimeter of the part.
Advanced Control: 4-Post Servo Press
The 4 Post Servo Press is recommended for trimming structural plastics, carbon fiber, or high-strength forgings. By utilizing Servo-Hydraulic control, you can precisely manage the "breakthrough" force, significantly reducing the noise and mechanical shock associated with heavy trimming operations.
Cold Forging: 4-Post Servo Press
The Straight-Sided Mechanical Press (also known as Straight Press) is recommended as high-speed cold forging press machine while the Servo Straight Press provides optimum precision control. Our mechanical forging press is available in crank press types, including single and double.
Engineering For
Edge Quality
Impact Shock Absorption: Our presses are equipped with advanced hydraulic cushioning to absorb the "breakthrough" shock when the material shears, protecting your dies from premature cracking.
Rapid Cycle Times: High-speed valves and optimized hydraulic circuits ensure that the press keeps pace with the fastest die-casting machines.
Parallelism & Precision: Precision-ground platens and heavy-duty guidance systems ensure that the trim tool meets the part with zero offset, providing a "burr-free" edge.
Material Compatibility for TRIMMING Presses
Trimming is a versatile process, but the “shearability” of a part depends heavily on its material properties. Below is a guide to the most common materials processed using our Trim, 4-Post, and Straight-Sided presses.
Aluminum Die Castings
Aluminum is the most common material for trim press applications due to its widespread use in automotive and electronic housings.
Characteristics: Relatively soft but can be “gummy” if the alloy has high silicon content.
Trimming Note: Requires high-speed shearing to ensure a clean break and prevent the metal from dragging or smearing along the trim edge.
Recommended Press: Trim Press for standard cycles or 4-Post Servo Press for structural vacuum castings.
Zinc & Magnesium Forgings
These materials are often used for high-precision, lightweight components that require extremely thin flash removal.
Characteristics: Zinc is very fluid and produces thin, sharp flash; Magnesium is lightweight but brittle.
Trimming Note: Low shear strength allows for lower tonnage but requires high precision in die alignment to avoid cracking the main body of the part.
Recommended Press: Trim Press.
Mild & Alloy Steel Forgings
Heavy-duty industrial and agricultural forgings often come out of the hammer with thick, tough flash.
Characteristics: High shear strength and high temperature (if trimmed hot).
Trimming Note: Requires maximum frame rigidity and massive tonnage. The “breakthrough” shock is significant, making hydraulic dampening essential.
Recommended Press: Straight-Sided Servo Press.
Industrial Plastics & Composites
Trimming is used to remove overflow from injection molding or to profile thermoformed sheets.
Characteristics: Highly variable; some plastics are brittle while composites (like Carbon Fiber) are abrasive.
Trimming Note: Often requires programmable stroke speeds to prevent shattering or “whitening” of the plastic edges.
Recommended Press: 4-Post Servo Press.
| SHEAR STRENGTH & TONNAGE GUIDE | ||
| Material | Typical Shear Strength (PSI) | Tonnage Requirement |
| Plastics / Composites | 8,000 – 12,000 | Low |
| Magnesium Alloys | 17,000 – 20,000 | Low to Medium |
| Aluminum (Die Cast) | 23,000 – 30,000 | Medium |
| Mild Steel | 45,000 – 55,000 | High |
