Composite curing oven


A composite curing oven is used to cure, anneal, dry, and harden synthetic and composite materials. The curing process for these composite materials frequently includes bagging and putting them under a vacuum while being cured. Each composite curing application is unique and GBM Oven’s experienced team designs and manufactures high-performance ovens to meet each customer’s specific process requirements. 

These out of autoclave (OOA) composite curing ovens are available electrically heated, gas-fired, or indirect gas-fired. As a standard, they are designed with a combination airflow arrangement which ensures even & uniform heat distribution throughout the work chamber and provides quicker heating rates and recovery times. They are typically guaranteed and certified for ±5° at 350° C temperature uniformity, but other tolerances and certification at other temperatures are available. Upon request, a Computational Fluid Dynamics (CFD) analysis can be used to optimize airflow, heat transfer, and overall oven performance. 


Out of Autoclave has become more popular as a cost-effective alternative to high-pressure autoclave composite curing. OOA processing removes the need to pressurize the entire chamber by using vacuum bag only (VBO) technology with tight vacuum tolerances. GBM Oven OOA industrial ovens allow you to cure various materials of complex contours, shapes, and sizes all while providing fast heat-up rates and cycle times, superior temperature uniformity, and an optimal cure.

Composite Curing: Composites are a reinforcing fiber in a polymer matrix that commonly needs to be cured to set the matrix. Many industries such as transportation, construction, marine, infrastructure, and aerospace, have realized the benefits of composites. Companies in the aerospace and automotive industries are using composite materials to help make their products lighter, faster, and more fuel-efficient.
