The vacuum hot press furnace is a device designed for heating and pressing materials in a vacuum environment. It is primarily used for processes like hot pressing, sintering, forming, and heat treatment. By maintaining a high-temperature, low-pressure environment, it ensures materials can be processed without oxidation or contamination. Widely applied in fields such as metals, ceramics, powder metallurgy, and composite materials, it is particularly suitable for manufacturing high-precision, high-performance materials.

Product Description:

The CY-IVP500-20T-SS is a vacuum rapid hot press furnace (VRHP) specially designed for densifying composite materials through rapid hot pressing under vacuum or protective atmosphere conditions. Powered by a 15KW induction heating system, it can quickly heat graphite molds and samples to a maximum temperature of 1600°C. The induction heating coil and graphite molds are housed in a stainless-steel vacuum chamber. A press system applies pressure of up to 20 tons, achieving a maximum unit pressure of 90 MPa.

Features:

Cost-Effective Sintering: Offers a cost-effective alternative to SPS sintering under specific process conditions.

Fast Induction Heating: Provides rapid and precise temperature control.

Specialized Molds: Includes composite molds that are easy to demold without damaging samples.

Enhanced Density and Microstructure: Rapid sintering minimizes grain growth, producing dense samples with fine grains and excellent electrical properties.

Efficient Process: Enables simple sintering processes, short sintering times, and ease of forming.

Application Example《Sintering Lithium-Ion Battery Cathode Materials Using a Rapid Vacuum Hot Press Furnace》

Process Steps:

1. Material Preparation: Select appropriate cathode material (e.g., NCM, LCO, NCA, LiFePO₄). Mix with conductive agents (e.g., carbon black) and binders (e.g., PVA).

2. Mold Preparation: Load powder mixture into molds made of quartz or metal, designed for high-temperature, high-pressure conditions.

3. Vacuum Processing: Clean the furnace, vacuum the chamber to 10⁻³–10⁻⁶ mbar, ensuring no oxidation or impurities.

3. Heating & Pressing: Gradually heat to 700–1000°C and apply 10–30 MPa pressure to enhance material density and reduce porosity.

4. Sintering: Maintain temperature and pressure for 1–3 hours.

5. Cooling: Allow gradual cooling to room temperature to prevent thermal stress.

6. Post-Processing: Remove the sample, polish, and perform quality checks using SEM, XRD, or electrochemical tests.

Advantages:

High density and uniform microstructure.

Minimal grain growth.

Superior electrical properties.
