Double Shear Double Punch Silicon Steel Cut-to-Length Line
High-Precision Transformer Core Lamination Production Machine

The JY-300 Double Shear Double Punch Cut-to-Length Line is a fully automatic production solution designed for high-precision processing of silicon steel coils into transformer core laminations. It integrates feeding, punching, notching, shearing, sorting, and stacking into one continuous operation, making it ideal for modern transformer manufacturers seeking efficiency, accuracy, and automation.

Product Overview

This advanced silicon steel processing line is engineered to produce:

Step-lap transformer core laminations
Full miter and half miter joints
Straight joint transformer sheets

By combining V-notch punching, hole punching, and double angle shearing, the system ensures precise geometry and consistent output quality for transformer core assembly.

Key Features
