It's a long way from raw materials through the mixture to the finished stone. Many plant components are involved in this process. Only if the system components are matched, can one be assured of a smooth process and economical operation of the block making plant.
The manufacturing of autoclaved aerated concrete products demands high standards for mixing and dosing of the aggregates, the control of the fermentation process and the control of each production step. Masa's aerated concrete installations are proven advanced technology processes, designed according to customers specific requirements. This approach allows complete solutions to ensure highly efficient, optimised processes resulting in consistent final product quality.
It's a long way from raw materials through the mixture to the finished sand lime bricks. Many plant components are involved in this process. Only if the system components are matched, can one be assured of a smooth process and economical operation of the sand lime brick production plant.
It's a long way from raw materials over mixture to the finished (Kerb)stone. Masa Kerbstone presses were developed to fulfill among other criteria, the special requirements of the "British Standard" kerbstones. This "British Standard" is still a condition in countries of the Middle East and the UK.
Masa plants and machines are installed and commissioned by our own experienced fitters. Masa relies on qualified personnel, trained in Germany.
The Masa Lifetime service extends far beyond the actual assembly and commissioning of a plant. Masa can rely on specific know-how and an industry experience of more than 110 years.
Do you need support with your machine? Masa Support scores in both quality and significantly improved accessibility. Whether "first aid" for technical problems, updates, functional expansions of your production plant or technical questions, the know-how provided by Masa Support covers a wide range of services.
One of the keys to increasing productivity and quality is continuous training of the machine and maintenance personnel.

Long-term planned - reliably delivered
New Masa plant control system for AAC plantsPorta Westfalica 30 Sep 2022 - Masa is renowned for the supply of solid, technically mature and reliable solutions. This includes the control system. The supply of the first AAC plant with complete TIA programming (visualisation system and program) was therefore strategically planned for the long term and implemented properly.
The control system is the brain of each production plant. It monitors and controls all relevant processes in the manufacture of AAC and ensures a safe and reliable course of operation at maximum availability of the plant. For the plant operator, the control system has to be a manageable instrument to handle the increasing complexity within the manufacturing process and the various plant areas. It should not be regarded as a cause for complexity, but as a chance to use the complex possibilities for a simple handling. Based on a further development of the PLC generation of Siemens and the required software for the PLC programming, Masa entered the world of TIA Portal to fundamentally revise the visualisation system and the control system architecture of the Masa plant control software.
With the new Masa plant control system, the customer thus receives - beside the excellent Masa machine technology - a high-quality and consistent control system for the complete plant. The clear user guidance guarantees a continuous production process with high availability. Beside the plant safety, the profitable operation of the AAC plant is another important aspect.
Milestones of the new Masa plant control system for AAC plants
- Continuous automatic operation: In the condition-controlled programming that has now been implemented, the current status of the individual assembly is registered by means of sensors. The possible conditions are stored, depending on the condition, a certain program sequence is started. This makes the handling of the individual plant areas easier to understand. In the event of a malfunction, the system offers a much faster, simplified return to automatic operation after the cause of the malfunction has been eliminated.
- Decentral configuration: In case of a malfunction, individual switch cabinets or control system parts can be switched off separately. With this concept, the total availability rate of the production plant remains high, even in case of a short interruption in a certain segment.
- Continuous visualisation system: Masa uses the TIA Portal toolbox to standardise the operation and visualisation of the plant components. The consequent and consistent operator guidance helps the customer as well as the Masa service staff to locate and eliminate possible disturbances within a short period of time. In each plant area, the individual levels of the visualisation follow an identical basic structure. The process currently going on in the chosen area can be followed in real time with the visualisation system.
- Uniform fault messages: The fault report texts were standardised and formulated more meaningfully. The fault message lines are now displayed uniformly and in short form. The fault message screen displays the faults in chronological order. Each fault message is consequently marked with an item designation so that the operator can find the actual spot of the cause of failure.
- Smaller automatic areas: Masa separates the plant in different automatic areas. Each area can, depending on its status, individually be operated in the modes “Automatic operation”, “Manual operation” or “Service operation”. The smaller the automatic areas, the smaller the area that has to be switched to manual or service operation in case of a malfunction. Masa made a reasonable new division and increased the number of automatic areas in an AAC plant to 48 now.
Direct line
A wide-ranging, excellent in-house competence throughout the complete manufacturing process is significant for Masa. Starting with the planning process and the realisation of the project regarding design and programming down to the acceptance of the project by the customer, Masa covers the complete range of know-how, also comprising process technology. When the project has been given over to the customer, the Masa competence team is still available. The "Electrical" competence team in Porta Westfalica was in charge of the current milestone "New plant control system".
