P series Continuous Vacuum Hot-press Furnace
Good Design Optimization / Temperature Uniformity / Fast Heating Speed /High Pressure Accuracy / Good Safety Performance
Continuous vacuum hot pressing furnace is a process of forming materials by hot pressing them under vacuum (or other atmosphere) conditions. The continuous complete set of equipment mainly adopts graphite resistance heating and a pressure head driven by oil cylinders. Apply pressure up and down. At high temperatures, the mutual bonding of solid particles in raw materials leads to grain growth. Voids (pores) and grain boundaries gradually decrease, and their total volume shrinks through material transfer. The density increases and eventually becomes a dense polycrystalline sintered body with a certain microstructure, thereby, material compression forming.
Continuous vacuum hot pressing equipment has the advantages of advanced technology, high degree of production automation, large processing capacity, and thermal stability. Advantages such as good product quality. Can greatly improve the production e˝ciency of enterprises and save labor costs.
Technical Data
Adopting a multi station design, continuous production can be achieved, resulting in doubled effciency;
Fast heating: heating rate of 10°C/minute (˛ 1600°C), heating rate of 5°C/minute (>1600°C); Good design optimization: The thermal field of the pressurized chamber has been simulated and calculated in thermal state, with very high temperature uniformity. The conÿgured heating elements and insulation layer are designed with modular optimization;
Good temperature uniformity: The average temperature uniformity is ±5°C (5-point temperature measurement, constant temperature zone 1000°C insulation for 1 hour before detection);
High pressure accuracy: using a hydraulic control system, the pressure accuracy is ˛ ±3‰; Adopting multi temperature zone control: reserving multiple temperature measurement holes for high-temperature monitoring purposes;
Good safety performance: Adopting HMI+PLC+PID pressure sensing control, safe and reliable; Good sealing performance: The dynamic pressure heads are sealed with corrugated pipes to ensure no air leakage;
High degree of automation: If an automatic loading and unloading system is selected, all processes can be fully automated, digitized, intelligent, and without the need for manual intervention.
