Box Type Ovens with sandwiched type panels. The insulation material used between the panels is 60kg/m3 rock wool and glass wool. The heating system is provided by electric elements that are made of Inconel.

There are special horizontal air ducts and blowing vents inside the oven to ensure homogeneous distribution of hot air through the oven.

The oven can be easily installed and used on plain ground. The sheet steel floor of the oven allows an easy entrance and movement for trolleys.

Factors to Consider When Buying a Composite Oven


In composite, all resins have a curing temperature which need to be consistently heated to. As all ovens have a max operating temperature and an operating range they are most effective at, matching the curing temperature to the operating range will give the best results.


The accuracy an oven can hold a temperature is called the uniformity and is often expressed as ± 3°C or ± 5°C etc. indicating the fluctuation of target temperature in the oven chamber. The more accurate the oven the higher the price so this should be matched to the specification of the resin being cured. Factors affecting accuracy include build quality, instrumentation quality, airflow around the oven chamber and calibration schedules.


Often expressed in litres with the width, depth and height, the oven chamber defines the maximum size of the parts that can be cured and the number of parts than can be cured at once. Although using an oven that is too big wastes energy.

Programming and Recording

Some composites and resins require heating in stages, at a specific rate, maintaining at the set temperature or even cooling at a defined rate. These ramp ups, set points and ramp downs are handled by the oven controller. Recording what happened during a process cycle is achieved with a temperature recorder.
