Automatic PLC Controlled High Temperature Spark Plasma Sintering Furnace

Principle & Applications

Spark Plasma Sintering (SPS) is an advanced powder metallurgy sintering process. The equipment loads metal and other powders into a mold made of graphite or other materials. Using upper/lower punches and electrified electrodes, it applies specific pulsed current and pressure to the sintering powder. High-performance materials are obtained through discharge activation, hot plastic deformation, and cooling.

Applications

• Hot-press sintering forming of various metals, non-metals, and alloy powders

• Preparation of functional ceramics, cermets, intermetallic compounds, and composite materials via hot-press sintering

• R&D and preparation of nanocrystalline materials

• Fabrication of gradient functional materials

Features

• Fast sintering speed, high efficiency, and high density of sintered samples

• DC pulse heating enables fast sintering with excellent energy efficiency

• High-frequency, high-power IGBT modules instantly boost current to several thousand or even tens of thousands of amperes, ensuring rapid densification of powders

• Proprietary patented technology guarantees stable high-current continuous output with ripple current ≤ 1%

• Key components use well-known imported brands, meeting industrial-grade standards for service life and output stability
