After applying a release gel to the mold's surface, the process begins by placing fiber textiles into the mold. These textiles are prepregs — composite materials containing a high-strength fiber that has been pre-impregnated with resin.
Once the molds have been filled, you vacuum the air out of the mold cavity and place the whole assembly first in a vacuum bag — this step enables equal distribution of pressure across the workpiece. An absorbent material, or bleeder, inside the bag facilitates easier air removal and absorbs any excess resin that may bleed out during the curing process. After removing the air from the bag, the container goes into the cpmpsite autoclave.
Then, the curing process begins. The temperature and pressure inside the autoclave rise, hardening the material and removing pores. Once the product has cured for the specified period, you remove it from the autoclave and place it in an oven to improve its durability. Then, after trimming and inspection, your composite is ready for use.

These three components also make autoclaves useful in industrial manufacturing processes, such as molding lightweight composite parts for space, aviation aircraft and other transportation applications.
There are a few methods used to cure composites. For example, one of the most common is the use of an oven with vacuum. But, there is a great advantage to using manufactured composite bonding autoclaves along with the vacuum. With an autoclave, you can heat and pressurize the vacuum bagged part at the same time. As a result, you have greater compression and better void removal.
An accurate autoclave curing of composite parts is a key process for many different industries that must be carried out in an autoclave. In order to achieve the desired results, the parts are treated through heating and cooling cycles at a given pressure, with variable parameters depending on their composition and the characteristics to be obtained in each process.
