In recent years, the colour sample collection market has undergone a significant evolution. While colour swatch books were once regarded primarily as sales tools, they are now increasingly recognised as strategic assets for companies, designers, window and door manufacturers, and paint producers. A professional colour sample collection must be accurate, consistent over time, and perfectly […]

“Tailor-made” Powder Coating
An in-house plant, flexible and high-performance.
MDM Campionari operates a state-of-the-art in-house powder coating facility dedicated to aluminium and steel components, featuring automatic and semi-automatic lines equipped with Wagner technology.
The plant is a key element of our value proposition, combining industrial-grade quality, maximum operational flexibility and full accessibility even for very small batches: starting from a single part, 1 m², 1 linear meter or small accessories.
01.
Instant color change system
One of our main strengths is the instant color change system, which enables the management of highly diversified production without minimum order constraints. This makes the plant ideal for small and medium batches, prototypes and samples, while remaining competitive compared to coaters focused exclusively on high volumes and limited color ranges.
02.
Pretreatment process
Upstream of coating, all components undergo a pretreatment process using ALIT chemicals, essential to ensure excellent coating adhesion and long-term durability, even in demanding technical and decorative applications.
03.
Dimensions
The plant can process parts up to 3.0 × 2.5 × 2.0 m, guaranteeing uniform film thickness, mechanical resistance and consistently high surface quality.
04.
The color offering
The color offering includes immediate availability of approximately 90% of RAL K7 colors, with gloss, matte and textured (wrinkled) finishes.
Coatings according to Pantone or NCS specifications are also available, while the remaining 10% of RAL K7 colors can be supplied on request.
After electrostatic application of epoxy powder, the component is transferred to the curing oven, where it undergoes a controlled thermal cycle. During this phase, the powder melts and subsequently cross-links, forming a continuous, high-build coating characterized by excellent anticorrosion performance and high surface hardness. The cycle is completed with controlled drying and gradual cooling.
Each phase of the process is digitally monitored, ensuring full traceability, continuous control of curing parameters and quality standards at the highest level of the industry. The result is a finish with outstanding mechanical and chemical resistance, effectively protecting against scratches, cracking, fading and chipping.
A tailor-made solution for customers seeking precision, versatility and reliability in powder coating, even for micro-production.
the most critical phase
Pretreatment
Pretreatment is the most critical phase in achieving high-quality powder coating.
Proper surface preparation ensures adhesion, durability, corrosion resistance and uniform finish.
Why Pretreatment Is Essential
- Improves coating adhesion to the substrate
- Enhances resistance to corrosion, moisture and chemical agents
- Ensures a clean, activated and uniform surface
- Reduces coating defects (peeling, blistering, delamination)
Our Pretreatment Stages
Degreasing / Pickling
Removal of oils, greases and surface contaminants using:
- Acid-based products
- High-efficiency water-based solutions
- Combined phospho-degreasing agents
Benefits: eliminates impurities that would compromise adhesion and surface quality.
Multiple Rinses
Essential to completely remove chemical residues.
Final Rinse with Demineralized Water
Ensures a neutral, salt-free surface prior to subsequent stages, maximizing coating adhesion.
Phosphating / Nanotechnology Treatments
Two approaches depending on material type and performance requirements:
Traditional Phosphating (Steel and Iron Substrates)
- Iron or zinc phosphates
- Ideal for steel and critical surfaces
- Creates a micro-crystalline structure optimal for coating anchorage
Nanotechnology Pretreatment (Aluminium and Light Alloys)
- Zirconium- / titanium-based conversion coatings
- More stable process parameters, lower consumption and reduced environmental impact
- Improved coating adhesion and extended durability
Deep cleaning, precise recovery, quality ready to restart
Paint stripping
a service integrated into our production cycle
In-house stripping strengthens our vertical supply chain: faster intervention, shorter lead times and maximum quality control on the finished product.
With our immersion chemical stripping system, we efficiently and safely recover painted items with defects or due for rework, restoring a clean surface ready for a new cycle.
The system removes all paint layers, returning the piece to its initial state.
Thanks to a modular setup, we handle different materials and geometries safely and flexibly, up to 1300×650×650 mm.
Stripping is often perceived as a “recovery” operation, but in advanced manufacturing environments it represents a strategic quality process.
Properly stripped components restore both aesthetic and functional standards, avoiding waste and ensuring performance equivalent to new parts.
Why Stripping Is a Quality-Critical Process
- Enables recovery of defective parts without compromising structural integrity
- Prevents scrap and costly rework
- Preserves geometries and surface tolerances
- Restores components to optimal condition for recoating
- Ensures continuity of aesthetic and surface quality standards
Finally, cleaning of hooks and hangers plays a crucial role in production quality, ensuring consistently clean contact between hanger and component and perfect electrostatic performance during coating.

MDM's Journal
In a market where customisation, speed of execution and attention to detail make an ever-growing difference, investing in new technologies does not simply mean purchasing more advanced machinery. It means offering customers new possibilities, greater design freedom and faster turnaround times. For this reason, MDM Campionari has chosen to strengthen its production department with the […]
Everyone uses it — from designers to sales teams, all the way to the end customer — and chances are you use it often too. For many, the aluminium colour fan deck is an everyday tool, invaluable when making colour choices that have a major impact on the final aesthetic of a product or project. […]
In the window and solar shading sector, the way a product is presented is an integral part of the sales process. Simply displaying it is not enough: you need to tell your brand’s story, guide attention towards the details that matter, highlight key features, and turn your showroom into a consistent and memorable experience. MDM […]
In a well-designed showroom there are many sales support tools, but the aluminium colour card is the one that truly makes the difference when it comes to choosing colours. It is not simply a holder for samples; it is a concentration of technical expertise, production precision and marketing strategy. MDM Campionari manages the creation of […]
Colour as a Global Language Assigning a universal classification to every colour stems from a very practical need: to communicate a proposed or desired colour clearly, unambiguously and consistently—even at a distance, without direct contact or an immediate physical reference. From this perspective, the RAL colour system can be compared to a true international language […]
