YLJ-HP2 Hot Pellet Press with Silicon Nitride Die, 550°C Max Temperature and 5T Digital Pressure & Temperature Control
The YLJ-HP2 is engineered to facilitate the precise pressing of ceramic, polymer, and ceramic-polymer composite powders into dense pellets. This equipment is particularly valuable in laboratories focusing on microwave dielectric materials, solid-state electrolytes, and semiconductor development. Its compact footprint enables operation within inert gas gloveboxes, such as argon environments, ensuring sample integrity during processing.
The press integrates a Silicon Nitride (Si3N4) heatable die set available in 12, 20, or 25 mm inner diameters, capable of reaching temperatures up to 550°C. A programmable PID temperature controller with a type-K thermocouple provides precise thermal management with ±2°C accuracy. Pressure application is controlled digitally via an oil-less electric press system, supporting loads up to 5 tons (approximately 150 MPa) with fine load accuracy of ±0.005 tons.
Key Features
- Silicon Nitride heatable die set with mold release components and heat insulation for uniform pellet formation.
- Programmable temperature controller with PID control and built-in type-K thermocouple for precise heating up to 550°C.
- Digital pressure controller with built-in load cell, enabling programmable pressure and dwell time settings.
- Electric oil-less press compatible with argon glovebox operation, including extension power cable with KF40 feedthrough.
- Pressure range from 0.1 to 5 tons with high accuracy and digital display for real-time monitoring.
- Compact design suitable for glovebox environments to maintain inert atmosphere during pressing.

Configuration & Operating Notes
The standard package includes the Silicon Nitride heatable die set with mold release rod and sleeve, upper and lower supporting plates, heat insulation plate with mica, heating jacket, copper adapter, and a programmable temperature controller. The electric oil-less press features a digital pressure controller with a built-in load cell and a digital display. An extension power cable with KF40 feedthrough is provided for glovebox integration.
Operators must wear protective goggles during use. Overloading the die beyond 5 tons is not recommended to avoid damage. For specific glovebox feedthrough solutions, contact the manufacturer or supplier.
