Explore our precision-engineered, heavy-duty hydraulic press configurations tailored for lightweight automotive stampings, composites molding, and structural alloy forging.
In modern industrial sheet metal stampings, single-action pressing often falls short when producing deep-drawn parts characterized by intricate geometries and demanding structural integrity. This is where double action hydraulic power presses represent a paramount engineering solution. Unlike a single-action press that relies on one sliding ram, a double-action press operates via two distinct moving assemblies: an outer slide (blankholder) and an inner slide (punch). The outer slide descends first, applying a calculated, uniform holding force along the perimeter of the sheet metal blank. This crucial phase restricts wrinkling and controls material flow. Immediately following, the inner slide descends to engage the drawing punch, stretching the material smoothly into the die cavity.
Our commitment at Chongqing Jiangdong Machinery Co., Ltd. focuses on balancing high-performance hydraulic systems with cost-effective engineering. Over the decades, we have optimized the mechanical and structural efficiency of our machinery to deliver solutions that global procurement managers catalog under cost-competitive brackets without sacrificing geometric tolerances, cycle rates, or operator safety. By utilizing advanced multi-channel closed-loop proportional valve systems, our presses offer dynamic adjustment of blankholding pressures throughout the drawing stroke.
Each machine features Finite Element Method (FEM) optimized frame designs. This guarantees minimal angular deflection under maximum nominal capacity (tonnage), resulting in longer die lifetimes and consistent drawing depths across multi-shift high-volume production schedules.

With electric vehicle (EV) regulations tightening globally, reducing structural vehicle weight is imperative. Stamping automotive structures from Ultra-High-Strength Steel (UHSS) and lightweight Aluminum alloys demands precision metal forming. Double-action drawing ensures that even extremely thin metallic alloys undergo draw forming without structural failure. This shifts the focus of manufacturers from basic stamping to dynamic, multi-zone force control systems.
Historically, double-action presses utilized fixed force margins. Today, the integration of proportional servo-valves allows the blankholder pressure to be dynamically altered in microsecond intervals during the drawing process. By reducing clamping force when metal flow needs to accelerate and increasing it when wrinkling is detected, our technology significantly reduces reject rates, keeping operational costs exceptionally low.
The convergence of industrial IoT and heavy forging equipment enables predictive maintenance schedules based on vibration analysis, oil contamination monitoring, and thermodynamic variances in the hydraulic manifolds. Our technical roadmap incorporates fully integrated smart sensors in the hydraulic cylinder assemblies, transmitting performance metrics back to central engineering systems for real-time diagnostics.
Procuring heavy machinery internationally introduces hurdles concerning shipping compliance, local industrial standards (such as CE, OSHA, and UL compliance), and technical installation. Jiangdong Machinery streamlines this process by offering certified components from international suppliers (like Bosch Rexroth, Siemens, and Parker) integrated into our systems. This guarantees that your maintenance team can source critical spare components locally while benefiting from our competitive Chinese manufacturing costs.
Over the next five years, Jiangdong Machinery is dedicating substantial R&D efforts to two primary technologies: Eco-Friendly Regeneration Hydraulics and Automatic Die-Leveling Calibration. The regenerative hydraulic circuits capture thermal energy and mechanical braking energy from the ram's return stroke, redirecting it to power the auxiliary cooling and control units. This system lowers energy consumption by up to 28% compared to traditional double-action setups. Concurrently, our automatic leveling system detects press slide deflection in real-time, correcting hydraulic distribution to preserve tooling geometry, even under off-center loading conditions.
A single-action press possesses a single moving ram that exerts pressing force onto the mold. In contrast, a double-action press has two independent rams: an outer slide that serves as a blankholder to grip the metal blank's periphery, and an inner slide that houses the drawing punch. The separate outer and inner slides allow for precise regulation of material flow during deep drawing, eliminating wrinkling or cracking of complex parts.
We supply complete documentation and engineering designs conforming to global industrial codes (OSHA, CE, and CSA). Additionally, we dispatch multidisciplinary service engineers to oversee foundation preparation, physical installation, pipeline flushing, software calibration, and initial trial runs. Furthermore, our remote monitoring software allows our R&D team in China to assist with troubleshooting and programming adjustments via encrypted network links.
Double-action presses are highly effective for drawing deep components using materials with high yield-to-tensile ratios, such as high-strength automotive steel (DP and TRIP steels), aluminum alloys (such as the 5000 and 6000 series), titanium plates for aerospace components, and stainless steel sheet metal for kitchenware and heavy industrial vessels.
Yes. Our double-action hydraulic presses feature advanced servo-hydraulic systems where the blankholding pressure is controlled dynamically via CNC profiles. This allows the blankholding force to increase or decrease throughout the drawing stroke relative to punch displacement. This dynamic adjustment is essential when forming asymmetric components where friction must be modulated at specific locations.
