Introduction to Large autoclave:
As the main production equipment for aviation composite parts, the hot press tank is a large pressure vessel with an integral heating system. Its common structure is a cylindrical body with one end closed and the other end open, providing necessary heat and pressure for the compaction and curing of advanced composite material products. Usually, the size of aerospace composite parts is very large, so the hot press tank needs to be larger. At the same time, some composite materials require higher pressure and temperature for molding, which requires the construction of special hot press tanks, but the cost will be quite high. Fortunately, most applications only require moderate temperature and pressure.

Application fields of Large autoclave:
Large hot press cans are mainly used in the aerospace industry, suitable for the production of high-strength carbon fiber, boron fiber, aramid fiber, glass fiber, and epoxy resin composite materials through hot press curing, such as aircraft wings, tail fins, partitions, brackets, cabin doors, fairings, and radars; It can also be used for curing solar cell substrates, large carbon fiber sheets, etc.
Overview and Process of Hot Pot Forming Technology:
The hot press molding process is a method of using the high-temperature compressed gas inside the hot press to generate pressure and heat the composite material blank to complete the solidification molding.
Hot press molding process: Preparation of prepreg, laying, placement on the mold, sealing in a vacuum bag, pushing into the hot press can, heating and pressure, and through physical, chemical and coupling effects, making the material meet the required requirements.
