JE21 Series Model D Open Back Adjustable Stroke Press – High-Precision Stamping Solution

The JE21 Series Model D Open Back Press with Fixed Table and Adjustable Stroke is engineered for manufacturers demanding superior precision and operational stability in metal stamping. Its open back C-frame structure ensures easy material handling and die changes, while maintaining excellent rigidity to handle heavy-duty production cycles.

The fixed table design offers unwavering stability, making it ideal for operations requiring repeatable accuracy such as precision punching, shallow drawing, and forming of high-strength metals. The adjustable stroke mechanism enables quick adaptation to different tooling requirements, allowing for fine control over press depth, cycle speed, and material deformation characteristics.

Crafted from high-strength cast iron with stress-relieved processing, the frame minimizes deformation under load. The mechanical drive system is paired with a robust clutch-brake unit to ensure consistent stroke motion and rapid stopping capability, enhancing both safety and productivity.

In demanding sectors such as automotive parts manufacturing, electrical enclosure production, and hardware fabrication, the JE21 Series Model D stands out for its ability to deliver micron-level tolerances at production-scale speeds. Operators benefit from a clear control layout, integrated overload protection, and easy access for maintenance — all contributing to reduced downtime and extended service life.

People Also Ask (FAQ)

Q1: How does the adjustable stroke improve production flexibility in the JE21 Series Model D press?
The adjustable stroke allows the operator to modify the ram travel length, enabling the same press to handle different die heights and forming depths without changing core components.

Q2: What materials can be processed using the JE21 Series Model D?
It is suitable for carbon steel, stainless steel, copper, and aluminum alloys, with thicknesses typically ranging from 0.5 mm to 6 mm depending on the tooling.

Q3: Is the JE21 Series Model D compatible with automated feeding systems?
Yes, it integrates seamlessly with coil feeders, straighteners, and robotic part handling systems, improving throughput and reducing manual handling.

Q4: What safety features are integrated into the JE21 Series Model D press?
The press includes a mechanical overload protection system, dual-hand control operation, emergency stop circuits, and guarding around moving parts to comply with international safety standards.

Q5: How does the fixed table design affect long-term precision?
The fixed table eliminates micro-movements that can occur in adjustable-bed designs, preserving die alignment and ensuring consistent product tolerances over long production runs.
