The composite autoclave is a key equipment for hot-pressing shaping of carbon fibers and resin matrix composites. In fact, the quality of the product is obtained inside the autoclave reaching an increase of mechanical features up to 20-30% compared to other methods of polymerization.The reliability and the precision of the cycles which can be obtained with HTMA autoclave, allowing to reach and keep high quality standards of the product, which is widely used in the high-tech fields such as aerospace, automobile, electronics, weapon, traffic, sports equipment and new type of energy, etc.
TPC (Thermal Processing Control) Software
HTMA composite autoclave equipped with advanced Thermal Processing Control (TPC) system. TPC is a PC-based control solution designed specifically for composite curing in autoclaves. It is developed on the basis of the advanced control systems that come from excellent domestic and overseas manufacturers. It is preferred control system for the most customers. The system has the login of user permissions, parts sensor selection, curing process curve setting, calling, saving and printing, automatic and manual operation, real-time data monitoring, recording, storage and printing, system status monitoring, event alarm, quality analysis, and so on.
Technical Advantages Of HTMA Composite Autoclave
1.No Annular Duct
Conventional autoclaves have an annular duct that is used to transfer air from the rear of the autoclave to the front. This air duct requires a larger pressure vessel and increase some extra ducting sheet metal .These factors will cause the high energy consumption on heating and cooling, increasing the use cost of customer’s.
HTMA composite autoclave does not require an annular air-duct and instead utilizes the floor as the forward air delivery system. It has a Sieve-Ventilation slots system in the rear and front of the autoclave. This unique design feature reduces the pressure vessel diameter by 100-150mm when compared to a conventional autoclave. This reduction in size and the elimination of the inner air duct reduces operating heating costs, pressurization costs, and equipment price.
2.Unique heating and cooling systems under the floor
In conventional autoclaves, the heater and cooling exchanger typically mounted at the rear of the autoclave. This rear-mounted approach requires the autoclave pressure vessel to be up to 1.5m longer to accommodate the components and the transition ducting at least.
The HTMA composite autoclave on the other hand incorporates floor-mounted heaters and cooling exchangers and therefore eliminates the need for the additional vessel length. This feature allows the HTMA autoclave’s vessel to be much shorter than the vessel used for a conventional autoclave. This positively impacts operational costs by reducing the amount of heating required and the amount of pressurization gas used for a standard cycle.
3.Advantage of Sieve-Ventilation slots system
HTMA composite autoclave utilizes Sieve-Ventilation slot panels to straighten and balance air flow in the autoclave.
Sieve-Ventilation slots are full-area, flow adjusting panels that facilitate the balancing and straightening of the air flow at the front and rear of the autoclave prior to entering/exiting the working volume. Unlike conventional autoclaves, an composite autoclave with Sieve-Ventilation slot technology has no dead-spots and therefore provide near 100% useable volume for your parts. The overall result is unequalled temperature uniformity down the entire length of the autoclave and uniform heating and cooling of your valuable part load.
