Pellet Pressing Dies and Press play a pivotal role as core tools in the laboratory powder forming process.
In fields such as materials science research, chemical testing, and catalyst development, forming laboratory powder samples is a critical step.
Not only does forming provide standardized samples for subsequent experiments, but it also enhances the accuracy and reliability of research data.
What Are Pellet Pressing Dies?
Pellet Pressing Dies are specialized tools designed to press powder materials into solid samples, typically used in conjunction with laboratory presses.
They assist researchers in compacting various powder materials—such as ceramics, metals, and polymers—into sheet-like, cylindrical, or other geometric sample shapes.
Made from high-strength tool steel or hard alloys, these dies offer excellent wear resistance and compression strength.
Classification of Pellet Pressing Dies
Cylindrical Dies
With a simple design, cylindrical dies are ideal for forming and testing various powder samples, including inorganic, organic, and metal powders. They can compress materials into disc or cylindrical shapes.
The die set includes a base, sleeve, pressing rod, spacer, and demolding sleeve. Standard sample diameters range from 2mm to 150mm, with extensive support for custom sizes.
Square Dies
Square dies are essential tools for pressing powder materials into square, rectangular, or triangular samples, used in conjunction with laboratory hydraulic presses.
Typical dimensions for length and width range from 3mm to 70mm, with customization available to meet specific needs.
Cylindrical Split Dies
These dies feature a three-piece detachable core, making it easy to remove pressed samples. They are specifically designed for powder samples that are challenging to form or demold.
Used with pellet presses, standard sample diameters range from 3mm to 80mm, with custom sizes available upon request.
Square Split Dies
Made from CR12 alloy tool steel, these dies offer high smoothness and exceptional hardness.
They are used for forming square samples, with typical lengths and widths ranging from 3mm to 80mm, and customizable options to meet specific requirements.
The die core consists of four detachable petals, allowing effortless sample removal, particularly for hard-to-form or rigid materials.
Classification of Presses
Manual Press
Featuring an integrated structure with digital or analog pressure displays, manual presses are easy to operate.
They typically offer a pressure range of 0-40T, making them economical and suitable for small laboratories or educational purposes.
Electric Press
Electric presses are efficient and require less effort, with precise pressure control and excellent repeatability.
They usually provide a pressure range of 0-60T and are widely used in material performance testing and high-precision experiments.
Automatic Press
Fully automated presses offer a pressure range of 0-200T. They are highly efficient, supporting multiple compression cycles, and are ideal for high-frequency experiments.
Heated Press
Heated presses can operate at high temperatures of 300°C or 500°C, combining heating and pressing functions.
They are suitable for research involving hot pressing and film formation of polymer materials, rubber, plastics, leather, textiles, and more.
Isostatic Press
Isostatic presses provide uniform pressure from multiple directions, avoiding stress concentration.
They offer high forming precision and are ideal for preparing high-density, complex-shaped samples.
