Coating and painting of small parts
Are you looking for a reliable and efficient solution for coating your mass-produced small parts? With our state-of-the-art Walter Trowal Rotamat system, we offer you a service that combines precision, flexibility and quality. Whether decorative coatings, bonded coatings or corrosion protection - we refine your workpieces and ensure optimum surface quality.
Your advantages:
- Uniform coating: The workpieces are continuously mixed in the rotating drum and enter the spraying area from different angles. This ensures a uniform coating thickness on all parts.
- Adaptability: The drum inclination is infinitely adjustable and can therefore be adapted to different workpiece geometries.
- Efficient drying: During the coating process, filtered, pre-heated air is fed into the drum, heating the workpieces to the optimum temperature. This leads to rapid drying of the coating material directly during processing, so that subsequent drying in a separate oven is not necessary.
- Environmentally friendly operation: The system is equipped with a four-stage exhaust air system that prevents harmful gases from escaping into the ambient air.
Our service in detail
Our coating process is based on a closed, rotating hot drum in which the workpieces are coated evenly with the help of automatic spraying machines. The parts are continuously mixed so that even complex geometries are coated seamlessly and homogeneously.
- Automated process control: The entire coating process is fully automated - from heating the workpieces to paint application and drying.
- Temperature control in real time: An infrared sensor measures the workpiece temperature directly on the surface to ensure precise adjustment to the material and coating.
- High material efficiency: HVLP (High Volume Low Pressure) spraying systems reduce overspray to a minimum, optimizing paint consumption and reducing environmental impact.
- Immediate readiness for use: There is no need for post-drying of the workpieces - the parts leave the machine dry and separated so that they can be processed or packaged immediately.
Applications - ideal for various industries
Rotamat technology is suitable for numerous industries in which precise surface finishing is required:
- Automotive industry: coating of O-rings, seals, valve stems or spring components with bonded coatings to minimize friction and increase longevity.
- Electronics & electrical engineering: Insulation coatings for electronic components such as ferrite cores or capacitor sleeves.
- Consumer goods & furniture industry: Coating of wooden handles, plastic knobs or metallic-looking plastic surfaces.
- Cosmetics and packaging industry: Decorative coatings for caps or cosmetic accessories.
- Tool and mechanical engineering: Corrosion protection coatings for screws, nuts or fasteners.
Coating types - individually tailored to your requirements
We offer various special coatings depending on the intended use:
- Decorative coating - for a visually appealing, high-quality surface with metallic or colored effects.
- Anti-friction coating - reduces friction and ensures smooth assembly, ideal for seals or mechanical components.
- Adhesive coating - enables elastomers to bond perfectly with other materials.
- Anti-corrosion coating - permanently protects metal parts against rust and wear.
- Insulation coating - improves electrical insulation for sensitive electronic components.
Your advantage - economical, environmentally friendly and reliable
With our Rotamat coating process, you benefit from high reproducibility, low costs and sustainable processes. The high application efficiency of 90 % drastically reduces material waste, and the closed drum prevents solvents from escaping. At the same time, all process parameters can be saved to ensure consistent quality at all times.
