Melco Steel, Inc. designs and builds autoclaves suitable for processing high-performance composite components. We construct composite autoclaves in compliance with ASME Boiler and Pressure Vessel Code Section VIII, Division 1 standards. Designed to fulfill specific composite curing and bonding requirements, our autoclave systems are available in standard as well as custom models with sizes up to 32' in diameter and 200' in length. Depending on specific application requirements, composite autoclave systems can be fabricated from carbon steel or stainless steel plates with thicknesses up to 8". Composite autoclaves can be manufactured to process parts at curing pressures as high as 3, 000 psi and operating temperatures close to 1500F. Our composite bonding autoclaves are suitable for processing parts used in medical and pharmaceutical industries. The key component of Melco Steel autoclaves is the custom-built, breech lock Harris quick-opening door. Standard features include part temperature monitoring, automated vacuum control, interactive screens, and multilevel security options. We specialize in developing computer controls designed specifically for composite bonding and curing autoclaves. Typical safety features of our composite autoclaves include 'Operator-Inside' alarms, over-pressure & over-temperature protection options, door safety interlocks, and blower motor cooling alarms. Combining over 25 years of autoclave as well as pressure vessel manufacturing expertise, we offer complete composite autoclave processing solutions, from design and fabrication to testing.Encapsulated blower motor eliminates the high maintenance necessary for through the vessel shaft sealing.Proprietary blower motor design allows operation at any combination of pressure and temperature.Engineered circulating fan assures excellent heat transfer to the load and exceptional temperature uniformity.Proprietary method of placing and securing insulation minimizes heat loss through the pressure vessel and minimizes operating costs.Location of typical electrical heating unit is shielded by cooling coil to prevent radiant heating of load.Cooling coil is a single pass heat exchanger designed for precise temperature control with ample provisions for thermal expansion to minimize thermally induced stresses and failure."Man-Inside" emergency alarm cables are provided on larger autoclaves which allows operator to completely disable all autoclave sub-systems.

glass laminating autoclaves are used in the production of diverse automotive, architectural, safety, and decorative glass. From small car windshields to large laminated glass, we build autoclaves in lab sizes and large, high production models. Designed to suit your specific load and laminated glass processing requirements, Melco Steel, Inc. autoclaves are available with auxiliary support equipment such as cooling, pressurization, as well as vacuum systems. To meet intensive production requirements, we provide autoclave systems packaged with heating power and air circulation units. The innovative design in these systems allows excellent heat transfer and accurate temperature uniformity. Safety features of our glass laminating autoclave systems include door safety interlocks, 'Operator-Inside' alarms, and blower motor cooling alarms. We manufacture glass laminating autoclaves in flat-sided workspace designs for maximizing load capacity. Our proprietary blower motor design is ideal for high temperature operations. A cooling system is used to limit motor capsule temperature. Operators can easily access the motor by removing the water-cooling supply and return lines of the motor capsule. The main autoclave cooling is controlled by a proportional valve that provides excellent temperature control and does not induce thermal shock in the cooling coil. Advanced computer control systems in our autoclaves provide intelligent, optimized cycle processing for maximum production and highest quality. We design computer controls specifically for glass laminating autoclaves to ensure high levels of accuracy and flexibility. Typical features of our control systems include guaranteed soak, glass temperature monitoring, automated vacuum leak checking, interactive screens, and multilevel security. Controls can also be configured to help reduce electrical demand charges. Melco Steel's advanced vacuum controls adopted from aerospace applications enable OEMs to flexibly process standard and special interlayer materials.

We design and fabricate unique autoclaves for curing concrete masonry to exact customer requirements. Although each concrete curing autoclave is distinctive, we apply proven techniques to address typical issues such as corrosion, thermal expansion, control system temperature feedback, and debris collection in condensate lines. Economical microprocessor based controls, overhead counterweight doors, and proprietary safety door options are some features of our concrete curing autoclaves. From large, high production units to lab size autoclaves, we handle different types of requirements. Using our patented Harris quick opening doors in such autoclaves prevents the door from opening under high pressures. These doors come with safety interlocks that comply with stringent OSHA standards. From designing the autoclave system to on-field installation, complete assistance is provided by our engineering staff. With extensive knowledge and fabricating abilities that ensure reliable autoclave operation, we have successfully completed and verified various standard autoclave designs. Our design and manufacturing operations comply with section VIII, division 1 of the ASME boiler and pressure vessel code.

Design and fabrication of complete dewaxing systems that meet exact end user requirements is our specialty. From simple manually operated autoclaves to completely automated self-contained autoclaves, different types of systems are custom developed by us. Although autoclaves can be built to virtually any size, the common sizes that we produce range from 3' to 6' in diameter and 3' to 8' in length. Each dewaxing autoclave is unique and warrants special attention in the preliminary design stage to ensure efficient operation, maintainability, and operational safety. For operational safety, we provide a unique door safety interlock mechanism, which uses redundant mechanical, electrical, hydraulic, and pneumatic devices. These devices offer complete protection against accidents such as opening of the door when high pressure builds up. Our autoclaves offer optimal performance even in the shortest cycle times. Designed to suit your specific load and processing requirements, our dewaxing autoclaves also come with auxiliary support equipment such as a steam boilers and wet or dry steam accumulators. With extensive experience, we refine our standard design concepts to consistently provide a precision piece of equipment. Our steam-injected autoclaves are common in the industry and known for their user-friendly operation.Encapsulated blower motor eliminates the high maintenance necessary for through the vessel shaft sealing.Proprietary blower motor design allows operation at any combination of pressure and temperature.Engineered circulating fan assures excellent heat transfer to the load and exceptional temperature uniformity.Proprietary method of placing and securing insulation minimizes heat loss through the pressure vessel and minimizes operating costs.Location of typical electrical heating unit is shielded by cooling coil to prevent radiant heating of load.Cooling coil is a single pass heat exchanger designed for precise temperature control with ample provisions for thermal expansion to minimize thermally induced stresses and failure."Man-Inside" emergency alarm cables are provided on larger autoclaves, which allows operator to completely disable all autoclave sub-systems.
