Laboratory 2300℃ High Efficiency Pressure Controlled Vacuum Hot Press Furnace For Hard Alloy Sintering

Introduction

QSH-VHP series vacuum hot press furnace is mainly used for teaching, scientific research and production. It is specifically designed for hot-press sintering and experiments of non-metallic materials, carbon composites, ceramic materials, cemented carbides, synthetic diamond tools and metal powder materials under vacuum or protective atmosphere. It can also be used for diffusion bonding of various materials such as ceramics, alloys and diamonds. Sintering and recrystallization under high temperature and high pressure in the furnace can greatly improve material density.
