From 6300KN to 25000KN: How GK Series Industrial Press Machines Define Heavy-Duty Forging

In the world of modern manufacturing, strength and precision go hand in hand. Industrial Press Machines play a vital role in shaping metal with high force and accuracy. The GK Series, a powerful line of knuckle joint presses, offers capacities ranging from 6300KN to 25000KN. These machines are designed to handle heavy-duty forging tasks with ease.

With compact bolster sizes from 700x700mm to 1200x1200mm, the GK Series fits diverse production needs. The structure varies by model – smaller models adopt an integral design, while the 12000KN version features a split structure for added flexibility. This combination of power and smart design makes the GK Series a reliable choice for manufacturers aiming for efficiency and durability.

Let’s take a closer look at what sets these Industrial Press Machines apart.

The Power Behind Precision Forging

Why Industrial Press Machines Matter in Modern Manufacturing

Industrial Press Machines are essential tools in today’s manufacturing world. They apply massive force to shape metal with precision. These machines help produce parts used in cars, appliances, and machinery. Without them, heavy-duty forging would not be possible on a large scale.

Product Highlight: GK Series Capacity and Structure Design

Force Range from 6300KN to 25000KN

The GK Series covers a wide range of force capacities, from 6300KN to 25000KN. This allows factories to choose the right model based on their production needs. Whether for medium or large-scale forging, these Industrial Press Machines provide powerful performance.

Bolster Size Versatility

Each GK Series press offers practical bolster sizes, ranging from 700x700mm to 1200x1200mm. This flexibility helps accommodate different tooling sizes. It also makes the press easier to adapt for different parts and processes.

Integral vs. Split Structure

For presses from 4000KN to 16000KN, we use an integral structure. This design provides stable and compact support. For the 12000KN model, we use a split structure to make handling and maintenance easier. Each machine is designed with practicality and user needs in mind.

Mechanical and Structural Excellence

Crank Toggle Mechanism with Bottom Dead Center Dwell

The GK Series Industrial Press Machines use a crank toggle mechanism. This design allows the slide to dwell at the bottom dead center for about 1/18 of the cycle. This short pause improves forming precision. It ensures each forged piece is consistent and accurate.

Pneumatic Clutch Brake Systems

Different models in the GK Series use different clutch systems. The GK-630 models use a pneumatic wet integrated friction clutch brake. The GK-800 to GK-2500 models use a pneumatic dry split friction clutch brake. Both systems are built for long-lasting performance and smooth motion control.

Precision Die Height Indicator

Each GK Series Industrial Press Machine is equipped with a high-precision die height indicator. It shows values with 0.01mm accuracy. This allows for precise adjustments during production. Operators can maintain stable performance and improve overall product quality.

Smart Control and Standard Features

PLC Control System

Our GK Series machines are controlled by advanced PLC systems. These systems are stable, safe, and easy to operate. The use of PLC ensures accurate control over each function. It also improves reliability in day-to-day industrial use.

Mechanical Lower Ejector Device

A mechanical lower ejector device is included as a standard feature. It helps remove forged parts efficiently after each press cycle. This device saves time, improves workflow, and reduces manual handling.

Design and Appearance

The GK Series is not just powerful-it looks professional too. Each machine is designed with a clean, solid structure. The compact form helps save space in the workshop. The machine’s appearance reflects its high-quality build and smart engineering.

Applications and Industry Use Cases

Fine Stamping and Extrusion

The GK Series Industrial Press Machines are ideal for fine stamping and extrusion. They perform well in detailed, high-precision work. Many factories choose them for jobs that require both strength and accuracy.
