Vacuum curing oven

Introduction to Vacuum Curing Oven:

The composite material curing oven with vacuum pumping function is an intelligent equipment designed specifically for the forming process of high-performance composite material hot press cans. This device integrates heating and vacuum control, and through a high-precision temperature control system (adjustable from room temperature to 300 ℃) and a vacuum negative pressure system (-0.098), it can effectively eliminate internal bubbles and volatiles in the material during the curing process, significantly improving the interlayer density and mechanical properties of composite materials. Equipped with a uniform hot air circulation structure and multi zone independent temperature control technology, ensuring consistent heating of large components, while integrating pressure safety interlock and vacuum leak monitoring functions, balancing process stability and operational safety. Widely used in the fields of aerospace carbon fiber components, new energy vehicle battery shells, wind turbine blades, etc., it is an ideal thermal equipment for composite material manufacturing, with both energy saving, environmental protection, and process traceability.

Working principle of vacuum curing oven:

Using electric heating. The heater is placed at the bottom and on both sides of the box, circulating on both sides, and evenly returning air from the top orifice plate of the lower air supply on both sides. On both sides of the interior of the room, there are air supply ducts. The fan sends hot air into the room through stainless steel ducts and forms a hot air flow around the rotating workpiece for heat exchange; The return air system is arranged at the top of the curing oven, and hot air enters the air supply unit again through the return air system for circulating heating, ensuring temperature uniformity in various areas of the curing oven, eliminating low temperature blind spots and hot air blind spots, thereby ensuring the quality of workpiece baking. The main control table controls the temperature throughout the entire process and linearly controls the temperature inside the working room according to the program. If the temperature control system fails, the working room temperature will continue to rise. When the working room temperature rises to the set value for over temperature alarm, the over temperature protection system will immediately act, cut off the heating power supply, issue an audible and visual alarm signal, and set up a vacuum pipeline to achieve vacuum curing function.

Temperature control principle: PLC programmable controller PID+SSR power regulator triggers non-contact power regulation and temperature control through zero crossing, adopts linear heating, reserves heating margin, sets up multiple vacuum tubes, and configures automatic valve intelligent control for on/off.

Application fields of vacuum curing oven:

Vacuum curing oven is mainly used in manufacturing fields with strict requirements for material properties, covering aerospace (such as carbon fiber composite fuselage, wings), new energy vehicles (battery shells, lightweight structural components), wind power energy (large blades, carbon fiber main beams), rail transportation (vehicle body and interior parts), and electronic packaging (high-frequency substrates, heat dissipation components) industries. Through vacuum environment and temperature control, it ensures that composite materials achieve low porosity, high density, and excellent mechanical properties during the curing process, meeting the requirements of high strength, lightweight, and weather resistance. It is the core equipment of advanced material forming technology.
