DDH Series Mechanical Presses

Ideal for Rotor and stator lamination stamping, battery grid forming, home appliance hardware fabrication, and perforated metal sheet stamping, the straight side crank press offers a pressing capacity from 85 to 630 tons and stroke speeds ranging from 80 to 500 spm. It can be configured with feeder, decoiler, straightener, and scrap chopper to form a fully automated stamping press line for high-speed precision metal stamping process.

Features
  • Constructed from high-grade cast iron, the frame is heat-treated under precise temperature control and naturally aged to release internal stress, achieving optimal structural stability.
  • The frame sections are fastened with base bolts and hydraulically preloaded, significantly enhancing rigidity and minimizing deflection under heavy loads.
  • A powerful and responsive separated clutch-brake assembly ensures precise positioning and quick braking response.
  • Reduces vibration and noise while improving tool life and maintaining long-term operational stability.
  • Manufactured from NiCrMo alloy steel and finished with heat treatment, grinding, and fine machining to ensure high strength and durability.
  • Equipped with gap-free axial bearings and elongated guide sleeves, the press achieves accuracy exceeding JIS special grade standards, extending die service life.
  • Minimizes thermal strain on the frame, maintaining stamping accuracy and extending machine lifespan.
  • The microcomputer interface provides intuitive visual interface control, allowing operators to monitor production quantity and machine status at a glance.
