400T Hydraulic Press Machine: Heavy-Duty Power for Precision Metal Processing
400T Hydraulic Press Machine: High-Pressure Performance for Heavy-Duty Metal Forming
Our 400T hydraulic press machine is a rugged, high-performance industrial solution engineered to deliver exceptional pressure, precise control, and reliable operation for heavy-duty metal processing tasks. With a nominal force of 400 tons, it combines advanced hydraulic technology with a robust structural design, making it an ideal choice for industries like automotive manufacturing, aerospace component production, construction machinery, and metal fabrication across global markets.
Core Advantages & Performance Highlights
- Powerful Heavy-Duty Capacity: Features a 400-ton nominal pressure and 800-ton maximum instantaneous pressure, enabling efficient processing of thick and high-strength metals (carbon steel up to 80mm, stainless steel up to 60mm, alloy steel up to 70mm). Perfect for hot forging, cold extrusion, deep drawing, bending, and stamping of large or complex metal parts.
- Precision Hydraulic Control: Equipped with a servo-hydraulic system and proportional pressure/flow valves, ensuring precise pressure regulation (±1% of nominal force) and stroke control (±0.02mm). The closed-loop feedback system minimizes deviation, guaranteeing consistent part quality even in long production runs.
- Stable & Durable Structure: Constructed with a one-piece cast steel frame (heat-treated for stress relief) and high-wear-resistant cylinder liners (hard chrome-plated), reducing vibration and deformation during high-pressure operations. Offers a service life of 20–25 years under standard working conditions.
- Energy-Saving Operation: Adopts a variable-displacement hydraulic pump and intelligent power management system, cutting energy consumption by 30–40% compared to traditional fixed-displacement hydraulic presses. The idle pressure reduction function further lowers power waste during non-processing periods.
- Safety & User-Friendly Design: Complies with global safety standards, featuring safety light curtains (Type 4), dual-channel emergency stops, overload protection, and anti-fall devices for the sliding block. The 15-inch touchscreen HMI with intuitive interface supports multi-language operation and one-click parameter storage.
- Versatile Processing Capabilities: Compatible with various tooling and auxiliary equipment (e.g., heating furnaces for hot forging, robotic arms for automatic feeding/unloading). Supports custom process configurations for diverse metal forming needs, from small-batch prototypes to large-volume production.
