SYA Series High-Speed Precision Punch Press

The SYA Series High-Speed Precision Punch Press is designed for continuous metal stamping, punching, blanking, bending and forming applications requiring stable operation and repeatable accuracy.

Available from 25 to 400 tons, the SYA Series covers a wide range of production requirements, from small precision metal parts to larger stamped components. The rigid welded steel frame, precision drive system, pneumatic balancing and hydraulic overload protection help maintain stable performance during continuous production.

The press can also be integrated with decoilers, straighteners, servo feeders and stamping dies to build a complete automated stamping line.

Key Features

● 25–400 Ton Capacity Range
Multiple tonnage options are available for different material thicknesses, die sizes and stamping requirements.

● High-Rigidity Welded Steel Frame
The machine body is manufactured from high-quality welded steel plates and receives stress-relief treatment to improve structural stability and maintain long-term precision.

● Precision Die Adjustment
Die adjustment accuracy reaches up to 0.1 mm, supporting accurate die setup and repeatable stamping production.

● Pneumatic Balancer
The pneumatic balancing system helps stabilize slide movement and supports smoother machine operation.

● Combined Clutch and Brake System
A high-performance clutch/brake unit provides smooth engagement, responsive stopping and reliable operation during continuous stamping.

● Hydraulic Overload Protection
The hydraulic overload protection system helps protect the press and die when abnormal loads occur.

● Wear-Resistant Key Components
Crankshafts, gears, screws and other key mechanical parts receive hardening, grinding or surface treatment to improve wear resistance and service life.

● Automation-Ready Design
The SYA Series can work with automatic coil feeding systems, transfer equipment and stamping dies for continuous production.

Designed for Precision and Continuous Stamping

The SYA Series is suitable for manufacturers that require a stable press for medium- and high-volume stamping.

Depending on the selected model, the press can be configured for different combinations of:

● Stroke length
● Stamping speed
● Die height
● Bolster size
● Slide area
● Press tonnage
● Die cushion requirements

The wide model range allows manufacturers to select the press according to the actual part and die rather than using an oversized machine for every application.
