Furthermore, the competitive landscape is characterized by key players focusing on strategic partnerships and technological advancements to capture emerging markets. For instance, the growing trend of customization in manufacturing is driving demand for versatile coating machinery capable of handling diverse applications, making Nordson a pivotal player in the evolving market landscape.
The Nordson powder coating machinery is an alternative to the wet paint process that covers items with a protective and decorative finish. Several types exist.
Curtain coater Nordson powder coating machinery:
The curtain coater is also known as a Nordson curtain powder coating machine. It is ideal for non-tapered and moderately tapered components. It uses the airflow to spread a curtain of powder over the substrates. The process is efficient and cost-effective, using only small amounts of powder to cover large surface areas. The machines are available in wide and narrow configurations. The wide one covers broad surfaces, while the narrow one is for small parts. A two-powder curtain coater is available if both primer and topcoat applications are needed simultaneously. The primer and topcoat will drop in and out as the substrate passes through the machine.
Nordson spray booth motion control powder coating machine:
This machine is ideal for complex-shaped items. An electrostatic field is created by a generator that is linked to the spraygun. The powder coating is then attracted to the item. The powder overspray is then collected by the extractor fans located in the spray booth. The coating process is then repeated.
ZoneFast conveyor systems:
The conveyor system is how items move through the system. The Nordson zones are variable to suit the application required. Generally, small size zones are used for gun spraying, while large zones are for curtain coating. Electric and pneumatic drives are available options. Additionally, dual-zone conveyors are used when part of the process is to pretreat the item.
Nordson Smart Connect System:
The Smart Connect System is an intelligent system used to control the powder coating process. It can connect with different elements of the coating process, like the conveyor speed and the powder spray booth parameters. The machine also has a touchscreen human interface to set items easily.
Nordson powder coating machines are versatile and can be used across various industries. Here are some industries where these machines are typically used.
Architectural:
Nordson powder coating machinery is typically used in the architectural industry to coat different kinds of building components, such as windows, doors, and curtain walls. The coating enhances these components' aesthetic appeal, durability, and corrosion resistance.
Automotive:
In the automotive industry, Nordson machines are used to coat various vehicle components, such as wheels, frames, bumpers, and trims. The coatings creates a tough finish that stands up to harsh environmental conditions like UV rays, moisture, and chemicals. Also, it assists in eliminating the need for a solvent-based coating while effectively reducing VOC emissions during the process.
Aerospace:
These machines apply powder coatings to protect aircraft components from wear, corrosion, and other environmental factors. They coat parts like brackets, housings, engine components, etc.
Electronic:
Nordson powder coating machines are used to coat electronic components, like circuit boards and connectors, with insulation coatings. These coatings provide electrical insulation, mechanical protection, and protection against moisture and chemicals.
Marine:
In the marine industry, Nordson machines are used to coat boat and ship components, like hulls, frames, and fittings. This coating provides protection against saltwater, UV rays, and marine growth.
Appliances:
Domestic appliance manufacturers often use Nordson powder coating machines to achieve a high-quality, durable finish on appliances like refrigerators, washing machines, ovens, and microwave hoods.
General manufacturing:
Manufacturers in diverse industries frequently use this machine to coat parts and components used in their production lines. Whether it is machinery parts, hardware, plumbing fixtures, or fasteners, powder coating enhances the durability and appearance of these components.
It is important to choose the right Nordson coating machine after thorough research of the requirements. The following factors can help users select the most suitable coating machine for their application:
Understanding Coating Requirements
It is crucial to understand the coating needs before proceeding. Analyze the substrate material that needs to be handled. Is it metal, plastic, or something else? Knowing the material will help in selecting a machine compatible with it. Figure out the part's shape and size. Does the part have complex geometries? Larger parts may require more efficient equipment to ensure proper coverage and uniform coating. Determine the desired coating's thickness, quality, and functionality. Consider the production volume and speed requirements. By precisely defining the coating needs, a suitable Nordson powder coating machine can be chosen to meet specific requirements.
Consider The Types of Coating Machines
There are different types of Nordson powder coating machines available for use. Booth and gun systems are great for manual or semi-automated applications where an operator manually aims the gun at the part being coated. Electrostatic spray systems attract the powder to the part being coated, resulting in minimal waste and overspray. TheAutomated powder coating systems work using robots to spray powder onto parts independently. Conveyor systems are best for high-production areas where parts move on a conveyor while being coated. The Nordson Select powder coating machine is designed with flexibility for manual and automated options. Depending on the needs, users can choose the coating machine from booth, spray, manual, automated, conveyor, or Select options.
Evaluate Booth Designs
With manual or semi-automated coating applications, users should examine the booth designs available. The booth provides a controlled area for powder application and recovery. Consider the powder booth's size and work area to ensure coated parts can fit inside. Choose a compact booth to use floor space efficiently. Compare the airflow systems between booths. A good airflow setup helps keep the workspace clean and safely exhausts excess powder. Explore both open and enclosed booth options. Open booths allow more airflow, while enclosed booths provide better overspray containment. Consider features like easy part access and efficient powder collection. By carefully evaluating booth designs, a suitable Nordson powder coating machine booth can be chosen for manual coating needs.
Study Powder Types
Selecting quality powder coating ensures coatings' durability, attractiveness, and other advantages. There are different kinds of powder coating materials for use. Epoxy powder coatings provide strong adhesive qualities and exceptional durability. Polyester powder coatings offer good resistance to scratches and fading when exposed to the sun. Hybrid powder coatings combine properties of epoxy and polyester, making them versatile for interior and exterior applications. Select polyurethane powder coatings for superior abrasion and chemical resistance. phosphates contribute to corrosion resistance on metal substrates is. Consider other specialized powder coatings, like chrome powder, that offer unique finishes or properties for specific areas. Users should choose the right powder coating material based on its benefits.
Q1: How much powder coating is on a part?
A1: The thickness depends on the part and its intended use, ranging from a few mils to much more. In general, appliances have a coating thickness of 2 to 3 mils, while automotive parts range from 3 to 5 mils.
Q2: How long does powder coating last?
A2: In general, powder-coated metal will last up to 20 years if it is exposed to direct sunlight and high humidity.
Q3: What Are the Pros & Cons of Powder Coating?
A3: The benefit of an item being powder-coated is that it becomes highly durable, providing a better and longer quality of the product. One of the main disadvantages is that, unlike paint, powder coating has fewer color options.
Q4: What Are Some Issues with Powder Coating?
A4: Issues with powder coating can include peeling, bubbling, streaking, and discoloration.
