In any painting operation it is fundamental to fully remove all oils, grease, dirt and oxides that are in the surface to be painted.

The process begins with one or several stages of industrial or demineralised/osmotized, degreasing washing, followed by deoxidation of the surface and the stage of anticorrosive treatment, which can be a chromate treatment for aluminium materials or phosphate treatment for steel material. Besides protecting the metal, these treatments also increase adherence of the paint to the substrate.

Recently, new nano-technological processes based in zirconium and silanes have been developed to eliminate the use of hexavalent chromium.

Each treatment solution is designed according to the customer’s requirements and in conjunction with the chemical supplier, in order to achieve optimal bath parameters.

We design our tunnels according to the latest demands in the market, not only applying the latest technologies but also allying good environmental practices.

The drying tunnel is made of high-insulation panels, which constitute a tunnel, where the previously wet pieces will be exposed to a transversal hot air current.

The heating process is carried out inside of a combustion chamber, where the heat/air exchange is done by forced air circulation through centrifugal fans, specific for temperature!

SINDURA® ovens have multiple diversified applications and in different areas, such as aeronautics, metalwork, wood industry, energy, plastic industry, automotive.

Aluminium heat treatments, composite materials, curing of plastic, curing of powder coating, term fixing of textile fibres, annealing to change the microstructure of a material, drying of ceramic material, etc.

When it comes to aeronautics, our ovens can comply with homogeneity according to the AMS2750E standard!

Throughout the centuries, man has been looking for ways to improve their production processes. That way, automation and robotics have emerged.

Automation is the use of “control systems”, “numerical control (CNC)”, “programmable logic controllers (PLC)”, “computing (CAD, CAM, CAx)” to control industrial machinery and industrial processes, reducing the need for human intervention.

A robot is a reprogrammable articulated mechanical device, which is able to, autonomously and using its processing capacity: obtain information from the surroundings using sensors; make decisions about what to do based on that information and a priori information; manipulate objects from the surroundings using actuators.

With the increase of competitiveness among several industries, SINDURA® uses a simplified, robust and effective concept of automation and robotics, so that the processes can be simplified and have the real use of the investments made, with the goal of increasing productivity and cost reduction.

We are specialists in programming PLC’s Rockwell and Siemens, Scadas and hmi’s Rockwell, Siemens, Proface, Beijer, programming of Kuka, Abb, Fanuc, Yaskawa robots, advanced programming between process and Sql databases for registration of information and real time monitoring and in any part of the world, of their machines and equipment.

The polymerization oven is a machine, which aims to join and polymerise the paint powders.

Its robust construction and high thermal insulation allow substantial savings in terms of energy consumption.

Manual washing booth, where the spray wash process takes place, for metallic materials.

The chemical process to be used is the degreasing and application of phosphate.

The booth consists of a product recovery system, consisting on a treatment tank, with a continuous decantation and filtration system of the product.

The Filtration and recycling system, cause for the contamination to be eliminated, allowing a substantial reduction in water consumption.

Our equipment is designed and built, always thinking about efficiency and durability, using high quality components, always ensuring good performance and efficiency.

We use the latest burning technologies, which raise the air to temperature more quickly, using less fuel, which translates into daily savings in operational costs.

We use genuine rock wool panels, with high density mineral wool that keep the heat inside of the oven , avoiding leakage and release of energy to the outside!

We have application equipment, manual or automatic, from the German manufacturer WAGNER®.

We have a large stock of consumables and qualified service technicians!

The booths with recovery are designed to increase productivity, quality of the product and profitability.

SINDURA® booths are ideal for high production powder coating applications because they are designed and manufactured for optimal airflow and maximum transfer efficiency.

As a traditional concept, we manufacture the booths in stainless steel, however, we have composite material booths and complete systems, for fast and efficient colour changes of the renowned WAGNER® brand.

As cabinas sem recuperação da SINDURA®, são soluções ideais para grande diversidade e dimensão de peças.

Permitem uma maior rapidez na troca de cor, já que o circuito de recuperação de pó é ausente.

A construção da cabina pode ser executada em chapa lacada ou painel Sandwich liso.

Equipada com um sistema de aspiração e filtração de pó, por cartuchos anti-estáticos, com filtração final por HEPA, evitando a saída por conduta e pressões negativas no interior do espaço fabril.

SINDURA® is the official integrator for the Portuguese market, of renowned booth manufacturer EQUIPOS LAGOS, Coruña!

We develop solutions for several activity sectors such as aeronautic, renewable, automotive, wood, railway and industrial.

Together, we implement control and robotic systems that guarantee the traceability of the process, a thorough thermal and humidity control and the best process conditions, adapting to the highest market demands.

Our painting z ensure that the preparation and application of the final painting are flexible to the different applied materials and coatings.

We offer the possibility of remotely controlling the processes and obtain information to continuously improve the consumption of energy, cycle times, application material consumption and generally all the precise data to optimise manufacturing, process control and traceability guarantees to extend the traceable certifications to the international standard on treatment conditions (temperature, humidity, process times,…)

The mechanical and basic structure of monorail conveyors, whose main element is a chain of links and cross bearings, on a double omega rail, guarantees reliable and long-lasting function. 

The chance of adapting the dirt trap, allowing a reduction of impurities prevenient from the movement of the bearings on the trap. Adapted for temperatures up until 250ºC.

The flexibility of the conveyor chain allows upward or downward inclinations, as well as adapting to the prevenient swellings from high temperatures.

Traction system through caterpillar-like track system type.

Automatic in-line lubrication system!

Composed by 1 double rail system, one traction for the motorised chain and one free rail for the conveyor cars, allow several routes and with different speeds within the same system.

Thanks to the mechanically simple structure, the control is dynamic and simples, multiple movements are synchronised using variable speed drivers, the speeds can be continuously adjusted.

Electronic systems, such as barcodes or RFID systems, allow identification of parts and production batches.

Locking stations are used to disengage the connection between the traction current and the transportation cars (trolleys), allowing, that way, for stops along the way, without involvement in the process and in the remaining of the parts rack, composed by the transportation cars. 

Electromechanical needles allow multiple choices for several routes that can lead to the solution.

Ciclones com recuperação de pó pneumática

Os cones de recuperação, devido à regulação sensível e à vibração produzida pelas mesmas permite peneirar, classificar, desempoeirar e filtrar partículas. 

Graças à sua simplicidade construtiva os cones de recuperação são de simples e rápido acesso para efetuar a limpeza ou para trocar de rede. 

Os suportes são fabricados em aço carbono, enquanto o cone é formado por uma rede de aço inoxidável de 400µ, suspensa por aro também em aço inox

Composto por um sistema de transporte de pó pneumático, com válvulas peristálticas, a instalar a jusante do cone vibratório, para automatizar o processo de transporte de pó de pintura recuperado no ciclone.
