How to Choose Between C-Frame Presses and H-Frame Presses
Share to : 
In stamping production, the press machine is responsible for shaping the material. Different material properties require different press tonnages. Common types of press machines include C-type and H-type, which differ in structural design and application scenarios. This article will help you better understand these two types of press machines and provide some selection suggestions.
About C-type Presses
C-frame press machines, also known as open punch presses or steel frame punch presses, have a C-shaped appearance when viewed from the side. These presses generally have a small footprint, employing a single-column structure with three open sides.
Features
1. Space Saving: C-frame presses have a compact structure and small footprint, making them ideal for workshops with limited space.
2. Flexible Adjustment: The wide range of open sides allows for easy monitoring and management of the stamping production process.
Application Scenarios
Commonly used in hardware, electronic products, and small to medium-sized household appliances, they are seen in tandem stamping(sometimes using H-frame presses).

About H-type Presses
H-frame press machines, also known as closed punch presses or gantry punch presses, have an H-shaped appearance when viewed from the side. These presses generally have a larger footprint and employ a four-column structure.
Features
1. Larger Tonnage: The balanced and robust double-column structure can withstand greater forces, allowing H-frame presses to be designed with a larger tonnage, making them better suited for processing thicker materials.
2. More Space: Although it occupies a larger area, the space available for die stamping is also greater, allowing it to process products with larger deformation volumes and larger specifications.
Application Scenarios
Generally used in the large household appliance and automotive industries, it is commonly found in multi-station transfer stamping.

| C-Frame Press | H-Frame Press | |
| Floor Space | Relatively Small | Relatively Large |
| Tonnage（generally） | Up to 500T | Up to 2500T |
| Workpiece size | Small to Medium | Medium to Large |
In summary, C-frame presses are suitable for small to medium-sized, high-speed stamping, while H-frame presses are suitable for medium to large-sized stamping with large deformation volumes. If you have any questions, you can contact us. Thank you for reading.
