Description
The GOANWIN GT Series Knuckle Joint High-Speed Press is specifically
designed for precision stamping applications, excelling in the production
of lead frames, semiconductor connectors, and other high-precision
components. This press utilizes a toggle linkage mechanism to deliver
exceptional rigidity, thermal balance, and operational accuracy.
Capable of performing advanced stamping processes such as deep drawing,
pressure holding, coining, cold forging, and net-shape metal forming, it is
built to meet the demands of high-speed and high-volume production
environments. Its innovative features, including servo die height
adjustment with memory, an advanced counterbalance system, and eight-sided
needle-bearing guidance, ensure reliable performance and extended die life.
The GT Series is the ideal solution for industries requiring precision,
efficiency, and durability in metal forming, from electronic components to
automotive applications.

Features
1.Maximized Knuckle Joint Efficiency
- High rigidity, thermal balance, and minimized deformation under heavy
loads.
- Simplified structure for enhanced productivity and ease of maintenance.

2.Servo-Controlled Die Height Adjustment
- Features memory functionality, enabling quick mold changes and improved
operational efficiency.

3.Advanced Counterbalance System
- Suppresses displacement of closed die height due to speed changes.
- Minimizes bottom dead center (BDC) displacement between first and second
punches.

4.Eccentric Load Resistance
- Equipped with a double plunger and eight-sided needle-bearing guidance,
enhancing slide stability under eccentric loads.

5.Quiet and Durable Operation
- Backlash-free clutch/brake system offers low noise and extended
durability.

6.Widest Bolster Sizes in Class
- Provides wide bolster dimensions for versatility in handling various
stamping applications:
60-ton: 1100mm (standard) or 1350mm (wide).
80-ton: 1200mm (standard) or 1500mm (wide).

7.Enhanced Operability
- Electronic rotary crank angle display for user-friendly operation.
- Extended slide adjustment range for greater convenience and precision.

8.Advanced Lubrication System
- Thin oil forced lubrication suppresses thermal deformation, maintaining
consistent product precision.
