Cold Sintering Electric Hydraulic powder Press

The Cold Sintering Electric Hydraulic powder Press is an advanced device specifically designed for the Cold Sintering Process (CSP). It facilitates the rapid sintering of materials under low temperature (typically between 25°C and 300°C) and high pressure (typically 50 MPa to 500 MPa), with the help of a liquid-phase assistant. This equipment is commonly used for manufacturing ceramics, composite materials, and metals with special functions. It is widely applied in electronics, energy, medical devices, and aerospace industries.

Product Description:

 The CY-CSP-40A is a cold sintering electric hydraulic press with a maximum pressure of 40 tons, and it features a heated single-axis mold with a maximum temperature of 250°C. This device is designed specifically for preparing ceramics, polymers, or ceramic/polymer composites through the cold sintering process. Materials processed with this method are commonly used in fields such as microwave dielectric materials, solid-state electrolytes, and semiconductors. The press is equipped with an electric hydraulic pump, an automatic timer, and a pressure limit switch to ensure the safety of your experiments.

Key Features:

Low-Temperature Sintering Capability:
Supports sintering at temperatures lower than traditional sintering processes (typically under 300°C), enabling the sintering of high-performance materials while preventing material degradation, oxidation, or phase changes that can occur at high temperatures.

Automated Operation with Intelligent Control:
The intelligent control system allows for programmed settings and real-time monitoring of temperature, pressure, time, and other parameters.

Energy-Efficient:
The cold sintering process significantly reduces energy consumption. The lower temperature sintering not only saves energy but also reduces environmental pollution and temperature control costs.

Flexible Mold Support:
The device supports a variety of molds, allowing for the sintering of samples of different sizes and shapes to meet various material and finished product requirements.

Wide Application Range:
In addition to traditional ceramic sintering, the cold sintering electric hydraulic press is widely used in metal sintering, composite material sintering, and other functional material manufacturing processes.

Environmentally Friendly:
With low temperature and low energy consumption, the cold sintering electric hydraulic press is more eco-friendly, reducing environmental pollution and reliance on high-temperature furnaces, in line with sustainable development goals.

High Strength and Density:
High-pressure sintering effectively enhances the density and mechanical strength of materials.

Technical Specifications:

Main Components:

Application Fields:

Electronic Components: Manufacturing high-performance ceramic capacitors, piezoelectric devices.

Medical Devices: Sintering biocompatible materials.

New Energy: Production of battery materials and solid oxide fuel cell (SOFC) components.

Functional Materials: Development of new wave-transparent materials, thermal insulation materials, etc.

Application Case: 《Using Cold Sintering Electric Hydraulic Press to Manufacture Solid Oxide Fuel Cells (SOFC)》

Process Steps:

1. Material Preparation:

Electrolyte Material: Such as Yttria-Stabilized Zirconia (YSZ).

Cathode Material: Such as La1-xSrxMnO3 (LSM) with a perovskite structure.

Anode Material: Composite material of NiO and YSZ.

Liquid Phase Medium: Use a liquid medium that helps in ion migration (like water or other solvents) to aid sintering at low temperatures.

2. Mixing and Pre-treatment of Raw Materials:

Mix powder materials with the liquid phase medium in proper proportions, ensuring uniform dispersion of the particles.

Use ball mills or ultrasonic dispersion equipment to ensure uniform particle size, improving sintering density.

Adjust the viscosity of the slurry for proper mold filling.

3. Mold Preparation:

Clean molds and apply anti-stick agents (like PTFE coating) to prevent sample adhesion.

Fill molds with the mixed slurry evenly.

Smooth the surface using a scraper or vibrator to ensure uniform thickness and shape.

4. Cold Sintering Operation:

Set appropriate pressure (typically 100–500 MPa) and temperature (typically 80–300°C) based on the characteristics of the SOFC materials.

Set the sintering time (typically 10–60 minutes, depending on materials).

Apply pressure and temperature evenly to ensure uniform distribution during the sintering process.

Maintain pressure and temperature to encourage particle rearrangement and liquid phase medium evaporation, completing the sintering.

Gradually release pressure and cool to room temperature to avoid sample cracking.

5. Post-treatment:

Carefully remove the sintered sample from the mold and inspect for cracks or defects.

Optional Re-sintering: Some samples may require additional sintering at moderate temperatures (600–1000°C) to improve mechanical strength and electrical conductivity.

Electrode Coating and Assembly: Apply cathode and anode materials onto the electrolyte surface, then sinter the electrodes.

Performance Testing: Test the SOFC's conductivity, mechanical strength, gas permeability, and other properties to ensure they meet design specifications.
