TSB ENERGY manufactures Rubber Curing Autoclaves, Rubber Curing Ovens, and Rubber Curing Machines.

Rubber curing autoclaves are specially designed for rubber baking, rubber vulcanization, tire vulcanization, tire retreading, and rubber curing processes. They are widely used in automotive, rubber-coated rollers, rubber hoses, rubber pipes, rubber balls, cable production, shoe soles, latex belts, tire repair industry, and rubber curing component manufacturing.

Our autoclaves are offered as turnkey solutions including advanced control systems, rubber loading trolleys, steam generators, air compressor systems, with heating options such as electric, steam, indirect steam, or indirect thermal oil, and optimal air circulation system.

Rubber is a high-performance engineering material formed by combining polymer-based binder resins with its elastic structure at macro levels. Similar to the heat treatment process of steel, rubber materials undergo precise thermal and pressure curing cycles to enhance their fatigue and durability properties.

Working Principle of Rubber Curing Autoclaves

Our rubber curing autoclaves apply both heat and pressure to ensure homogeneous and flawless curing of rubber materials. During this process, the autoclave prevents air voids within the rubber products as they cure under high temperature and pressure. Temperature and pressure settings are precisely programmed based on each product recipe, rubber type, and desired mechanical properties.

Design: All our rubber curing autoclaves are designed and manufactured in horizontal or vertical constructions, single or double door, with manual or hydraulic-pneumatic arm options, opening from the side or top, in accordance with EN 13445, AD-2000 Merkblatt, Lloyd’s Rules, TRD, DIN, EN, PED 2014/68/EC, and ASME Section VIII Div 1 standards. All electrical components are UL labeled and wired to meet National Electrical Code requirements.

High-load clamp components are subjected to ultrasonic crack tests and fatigue tests using analysis software before assembly. According to customer requests and plant layout, door opening and closing mechanisms are custom designed.

In TSB ENERGY rubber curing autoclaves, air circulation is front-to-back with our proprietary baffle design ensuring turbulent flow and full contact with all interior surfaces. This turbulent flow allows rapid and evenly distributed heat input to rubber materials, achieving temperature uniformity within ±1°C.

Our oil cooling unit provides unmatched safety. Heat load inside the autoclave is transferred from the internal oil heat exchanger to the external exchanger. Thanks to 3-way proportional valves providing 0.1% precision, an exact cooling curve is offered to customers.

Rubber curing autoclaves are delivered compact on a single chassis, ready for operation. Only electrical and cooling water connections are required.

TSB ENERGY autoclaves are designed to provide savings during operation, not just at purchase.

Ease of Use and Maintenance: User-friendly controls and easy access to components simplify operation and maintenance, minimizing downtime and operating costs. One-button start, automatic self-diagnosis with safety shutdowns, and a control panel with maintenance alerts based on usage make autoclave operation safe and intuitive for operators. With advanced remote connection solutions, our technical team can provide fast support anywhere in the world.

All safety devices are monitored by PLC. Necessary safety measures are activated in alarm conditions. Rubber curing autoclave control is performed by operators via HMI, where active and historical alarms can be viewed. Alarm and operational status are transmitted to other systems via digital (dry) contacts. Remote data collection and autoclave status information are accessible through ModBus, Modbus TCP/IP, and Profinet protocols.

Commissioning is carried out by our expert engineers with full-day, on-equipment training supported by documentation.

Safety: Safety and standards are our top priority. Our rubber curing autoclaves are equipped with advanced safety features such as overpressure and overtemperature protection, RFI-based front door locking sensors, Pilz safety relays against potential risks, mechanical front door lock system, and emergency shutdown mechanisms.

Material: The shells and domes of our rubber curing autoclaves are manufactured from P355GH or P460NL boiler steel plates in compliance with EN 10028-2, selected based on operating temperature and pressure. Nozzle pipes are produced from EN 10216-2 compliant seamless boiler tubes of P235GH or P265GH grade, while clamps are made from forged P355NH steel (hot rolled rings) or drawn S235JR, S355JR materials.

Efficiency: Our R&D department has developed a fan hood unit that increases airflow velocity and pressure inside the autoclave, enhancing air circulation speeds while reducing the required electric motor power.

All our autoclave vessels feature proportional valve control, preventing unnecessary heat input. Additionally, the entire structure, including front and rear doors, is insulated with 50mm thick ceramic wool of 1260°C and 128kg/m³ density, minimizing heat loss.

Eco-Friendly Design: Our emission-free, electric rubber curing autoclaves help reduce your carbon footprint and achieve carbon neutrality goals.

What is a Rubber Curing Autoclave?

A rubber curing autoclave is a specially designed pressure vessel where rubber gains strength and elasticity through vulcanization under high temperature and pressure. These autoclaves transform rubber compounds to the desired hardness, durability, and sealing properties for industrial use. They are indispensable in producing gaskets, hoses, insulation elements, and technical rubber parts. Heating can be provided by thermal oil, direct steam, or electric energy. With our rubber curing autoclaves, you achieve high process efficiency, homogeneous curing, and maximum product quality.

When is a Rubber Curing Autoclave Used?

A rubber curing autoclave is used not only to shape rubber but also to enhance its chemical structure. It is preferred for thick, complex, or multi-layered rubber products requiring vulcanization under high temperature and pressure where standard press methods are insufficient. Thus, gaskets, heavy-duty hoses, and special industrial rubber parts gain longevity, flexibility, and wear resistance.
