Continuous-Flow Devices  Manufacturers, Traders, Suppliers

We can deliver ready for use machines with transport systems manufactured and configured according to customer specifications.
The following features can be part of our Primer Units:
Crossfeed transport systems allow automatic loading and unloading of roller conveyors. In the areas of coating and drying, a chain conveyor transports the parts safely and smoothly and in the best position. Components stored outdoors first pass through a blow-off station. A preheater then brings the material to the best working temperature for the next stage. A shotblast system removes rust and scale.
Within the automatic coating system area, sensors recognise the contours of the parts to be coated completely. Using this information, the application of coating components is precisely controlled via airless spray guns. A delivery system automatically allocates the required paint. Exhaust systems remove paint particles from the working environment. Dry or biological filters separate and collect these particles from the air. A bottom film for multi-shift use facilitates cleaning. Each active device can be accessed from outside the chamber providing trouble-free maintenance.
After coating, the material is transported through an evaporation and drying area. All phases of the process are controlled via the operator panel. Parameters can be keyed into a menu-driven programme or preassigned application sequences can be used.

Our programme covers requirements for fully
automatic coating machines with transport systems, as well as special
working environments with highly sophisticated units for coating
processes by qualified workers.
Steel fabricators and steel
stockholders use our protective coating units for all current sizes of
steel profiles, plates and pipe exteriors.
Our finishing systems are selected bysteel fabricators to coat welded constructions.
Pipeline
system producers take advantage of our automated systems to coat pipe
interiors.Our systems to coat large surfaces of differing materials,
such as double use coating chambers and environments for manual
applications, are specifically for shipbuilders, road and rail vehicle
manufacturers and for repair shops and garages.
Laboratories
specialising in finishing, being part of the paint industry, profit from
our automated equipment for coating colour testing sheets.

Planning, implementation, project management, service - from joint planning through commissioning and beyond we provide you with the experience of our engineering and installation teams.
Our conveyor systems are used for the intra-company flow of materials of general cargo, as well as for linking production machines. We deliver complete conveyor systems for, among others, the food, beverage, glass and chemical industries.
Installation & Commissioning by our experienced specialist installers worldwide Highly specialized installers available at any time
Production support, line optimization, spare parts inventory, conversions - a well-stocked warehouse and our metal-cutting production ensure a reliable supply of spare parts.

Since 1931 Walther Trowal has been developing and producing systems for the refinement of surfaces. Initially focusing exclusively on mass finishing – the term “Trowalizing” originated from the company’s cable address “Trommel Walther” – Walther Trowal has continuously expanded its product portfolio.
Over time the company has developed a broad range of machinery and systems for mass finishing, shot blasting and coating of mass produced small components.
With the invention of new systems like, for example, drag finishing and the development of special finishing methods for 3D printed components, the company has proven its innovative capabilities again and again.
Trowal develops and implements complete surface treatment solutions that can be seamlessly integrated into linked production systems existing at the customers. This includes the entire process technology, perfectly adapted to the specific surface finishing requirements of the work pieces: Equipment and the respective consumables always complement each other in a perfect manner.
Each individual work piece and each manufacturing process must meet special technical requirements. That is why the experienced process engineers in our test lab, in close cooperation with the customers, develop the optimal process technology for the finishing task at hand. The result: Work piece surfaces that meet exactly the required specification with short processing times and a high degree of consistent, repeatable results.
