High-Precision Straight Side Press Machine | S1 Series Mechanical Press

The S1 Series Straight Side Press is a high-precision mechanical stamping solution designed for medium to heavy-duty metal forming applications. With a wide tonnage range from 350 kN to 3150 kN, it is an ideal choice for manufacturers in automotive, appliance, hardware, and industrial component sectors.

Key Advantages of the S1 Series:

Precision Forming Performance: High stroke accuracy and adjustable die height allow for superior part quality in both shallow and deep forming.
Flexible Stroke Speed: Operating speeds up to 100 strokes per minute (spm), supporting both high-speed production and high-force operations.
Air or Water Cooling Options: Equipped with reliable cooling systems to support continuous, stable performance during long production cycles.
Heavy-Duty Table and Slide: Large bolster and slide plate surfaces accommodate multi-stage dies and customized tooling layouts.
Integrated Pneumatic System: The 0.55 MPa standard air pressure system provides consistent slide movement and improved energy efficiency.
Compact to Industrial Frame Options: Multiple machine sizes are available to match production floor layouts and throughput targets.

Applications:

Precision metal stamping for automotive brackets, mounts, and reinforcements
Electrical enclosures and appliance shell production
Sheet metal parts in industrial machinery
Progressive die and transfer system integration

Whether you need a press for high-precision punching, progressive die stamping, or modular transfer operations, the S1 Series is built to deliver accurate, stable, and efficient results across diverse forming scenarios.
