YB32 SERIES
Four-Column Double-Action Hydraulic Press
Aluminum Stretching · Stainless Steel Forming Specialist
Specially designed for aluminum product factories and stainless steel product factories, with longer stroke, larger worktable, and smoother operation
Product Overview

The YB32 series four-column double-action hydraulic press is specially developed by Foshan Chengda Hydraulic Equipment for aluminum product factories and stainless steel product factories. It is widely used for aluminum sheet stretching, aluminum product pressing and forming, stainless steel product pressing and forming, and many other processes.
Compared with same-tonnage machines, the YB32 has been comprehensively upgraded in key indicators including oil cylinder stroke, worktable size, no-load running speed, and stretching speed switching, delivering smoother operation and more stable performance.
The equipment integrates moving beam two-stage speed control, upper and lower limit protection for both main cylinder and blank-holder cylinder, automatic counting, and grating safety protection, ensuring both production efficiency and operator safety.
Core Features
Two-Stage Speed Control
Moving beam supports no-load fast speed, slow working speed with profiling, and stretching speed for flexible process adaptation.
Upper & Lower Limit Protection
Main cylinder and blank-holder cylinder are equipped with upper and lower limit protection. Position setting is simple and quick.
Safety Protection + Auto Counting
Multiple safety devices combined with automatic counting function for worry-free production.
Low Energy · High Efficiency
Low energy consumption design, stable running, lower overall operating cost.
Seven Upgraded Designs
Compared with traditional models, YB32 has been upgraded in the following 7 core components.

1 · Lower Cylinder Plunger Upgrade
Hard chrome-plated steel + wear ring structure to prevent plunger cracking.
2 · Sealing Ring Upgrade
Lower cylinder uses imported combined sealing ring, service life over 15 years without replacement.
3 · Column & Piston Rod Upgrade
Medium-frequency heat treatment + hard chrome-plated surface for higher strength and wear resistance.
4 · Ejector Cylinder Control Upgrade
Supports independent inching control for more flexible operation.
5 · Hydraulic System Upgrade
Cartridge valve design with large channel, high flow rate, fast speed, low noise, and low heat generation.
6 · Electrical Control Upgrade
24V microcomputer single-chip control, no intermediate relay, no contact, stable, durable, and easy to operate.
7 · Safety Protection Upgrade
Wide-range grating safety protection device for safer operation.
