Overview of Vacuum Sintering Furnace

Vacuum Sintering Furnace is a high-end equipment designed for high-temperature precision sintering process, which is widely used in the sintering and dewaxing of metal powder products, MIM (Metal Injection Moulding) parts, optoelectronic components, cemented carbide, magnetic alloys, ceramics and rare refractory metal materials. The equipment is available in both low-temperature (up to 1300°C) and high-temperature (up to 2200°C) configurations to meet the process requirements of different materials, and is the core equipment for achieving high-quality sintering in the scientific research and industrial fields.

1. All-round safety protection

Equipped with multiple intelligent alarm systems (such as over-temperature, abnormal vacuum, cooling failure, etc.), real-time monitoring of the operating status of the equipment to ensure the safety of the equipment and process, and minimise the risk of accidental shutdown.

2.Precise temperature control

The maximum heating temperature reaches 2200℃, and the low temperature section and high temperature section adopt molybdenum/graphite dual heaters intelligent switching technology, combined with PID high-precision algorithms, to achieve ±1℃ temperature control accuracy and ±5℃ furnace temperature uniformity, to ensure the consistency of the microstructure of the material.

3.Intelligent process control system

Full process automation: the computer system presets 30+ kinds of process curves and supports one-key call for parameters such as heating rate, holding time, cooling gradient, etc., which is suitable for the differentiated sintering needs of metal powder, MIM products, ceramics and other materials.

Precise switching of dual-temperature section: low-temperature section (≤1300℃) adopts silicon molybdenum rod to control temperature, and high-temperature section (1300-2200℃) automatically switches to molybdenum/graphite heaters, with temperature control accuracy ±1℃ and furnace temperature uniformity ±5℃.

4.Ultra-high temperature vacuum performance

Limit temperature and vacuum: the maximum working temperature of 2200 ℃, cold limit vacuum up to 4 × 10-³Pa, pressure rise rate of ≤ 0.5Pa / h, to ensure an oxygen-free environment to eliminate the material oxidation, densification is enhanced to more than 99.5%.

Double safety guarantee: Equipped with 16 real-time monitoring modules (temperature, vacuum, water-cooled flow, etc.), automatically activate sound and light alarms and emergency shutdown protection when triggering abnormalities.

5. Modular expansion design

Multi-specification compatibility: Providing five chamber sizes from 300×300×450 to 800×800×1200, with a loading capacity of 100-800kg, it supports the whole scenario coverage from scientific research trial production to industrial mass production.

Optional function upgrade: optional dewaxing module (degreasing rate ≥98%), hot pressure system (pressurised to 100MPa), to meet the demand for integrated moulding of special materials such as cemented carbide and super-hard ceramics.
