Machines Start-up

We have a trained team to start up machines with the Natreb quality standard and in a short time.

Reducers Reform in General

With extensive experience in the manufacture and assembly of high power reducers, the Technical Assistance team is highly qualified for the recovery of gear reducers. We have Natreb’s technical staff for evaluation and possible resizing, the Machining Sector with gear generators and grinders and quality control able to inspect special gears.

Corrective Maintenance

The Natreb Technical Assistance team is aware that Corrective Maintenance must be assertive.

Technical Assistance Natreb is fully integrated with the Spare Parts sector and the entire Productive sector of the company, which means that the average time of service to ceramists is considered the best in the segment.

Preventive Maintenance

It is necessary to prevent stops and failures of parts and components of the machines by performing an active preventive maintenance.

The Natreb Technical Assistance team is prepared for training and guidance for ceramic operators, aiming to optimize strategic stops, increasing efficiency, and reducing the risks of breakages and machine degeneration.

Ceramics Consulting

Natreb has a team of qualified professionals with experience to guide and encourage the necessary changes in its production process.

The work begins with a diagnosis through our face-to-face, laboratory analysis or a problem that comes from the client.

Our goal is to present the newest tools and practices to solve, maintain and increase the yield in all stages of the manufacturing process.

We seek resolution with the use of measurement equipment for data collection and existing practices in current processes together with qualified professionals in different sectors of the ceramic process.

The Natreb team can also develop projects for your production line and present which equipment and solutions can offer you improvements through 3D plans and layout to visualize your future investments.

Our work within the ceramic industry can be presented in the following stages:

– Mass development and adaptation for the preparation sector.

– Formulation and suitability of masses for better drying and firing.

– Increased production of the extrusion process.

– Nozzle adjustment.

– Adjustment and suitability for the natural and artificial drying process.

– Adjustment and adaptation to the firing process, aiming at reducing time and fuel.

– Development and solutions to problems in the finished product.

– Assembly and adaptation of a support laboratory in the Manufacturing process.

– Technical training to perform the daily tasks of the laboratory and other sectors.
