Selecting the Best Provider for a Coater

In choosing the best coater provider for you, it is important to assess your industry needs, production volumes and technology requirements. Use the following guidelines as a basis for evaluating potential coating partners.

1. Coating provider experience: Choose those who have experience servicing your industry sector. For example, Upper Shell is the only company that specializes in LTCC/MLCC ceramic coatings, while Nordson manufactures machines for high volume automotive coating.
2. Flexibility in Customization: Choose coater providers who will provide custom solutions for your needs; like Gema and ABB/Sames Kremlin offer customized robotic cells for complex part coatings while Gema provides modular systems that can grow with your business.
3. After Sales Support: Make sure that the coating provider has a worldwide service network to support their coatings machines during the lifecycle of that machine. Nordson and ABB provide 24/7 technical support; reducing customer downtime.
4. Focus on Sustainability: If your company is committed to sustainability; Gema and Sames Kremlin provide equipment that utilizes Low VOC and other waste reducing technologies; therefore, assisting companies in maintaining compliance with environmental regulations.

Frequently Asked Questions on Coating Machines and Their Providers

What are the types of coatings?

There are four primary types of coatings:

1. Powder Coating (Dry Powder): Powder can be electrostatically applied and cured for a long-lasting finish, making it ideal for use on metal surfaces. Nordson and GEMA are the manufacturers of powder coating systems.
2. Liquid Coating (Paint or Varnish): You can use spray guns to apply paint or varnish to different products, or you can use automatic liquid coating systems. This applies to the automotive and furniture industries. Sames Kremlin specializes in creating and manufacturing liquid coating systems.
3. Ceramic Coating: Heat is used to cure the ceramic coating; this method provides a durable finish, protects against corrosion, and is used in aerospace and electronics. Upper Shell provides ceramic coating solutions for LTCC and MLCC.
4. Adhesive Coating: You can use pressure-sensitive or heat-activated adhesives to create a seal for packaging and assembly. Nordson supplies adhesive coatings.

What Are the Start-up Costs of a Powder Coating Business?

Start-up costs for a business that uses powder coating will typically range from $50,000 to $200,000. This amount will cover a basic powder coating system (between $10,000 and $50,000), a booth and ventilation equipment (between $20,000 and $100,000), and an initial inventory of materials. If you are starting a high-volume operation, you could exceed $500,000 for a fully automated powder coating line.

What Is the Cost of a DLC Coating Machine?

DLC Coating Machines can cost between $100,000 and $500,000. The price of a DLC Coating Machine depends on how large of a chamber it has, the equipment used to coat the material, the thickness of each layer of coating during the application process, and the degree of automation of the machine. Teer Coatings are a manufacturer that specializes in DLC Coating Machines.

What Are Some Common Issues With Coating Machines?

There are several common issues that you might encounter with the use of coating machines, including: uneven coating thickness caused by clogged nozzles; excess material waste due to low transfer efficiency; and excess downtime for equipment due to a lack of maintenance. To alleviate these issues, make sure to choose a coating machine supplier that has high-quality, advanced automation (like Nordson's AI quality control) and is willing to offer routine maintenance support on your equipment.

Selecting a coating machinery supplier is an important strategic decision that will directly impact the quality of your product, your cost of operations, and how competitive your product will be in the marketplace. If you are looking to purchase a general-purpose industrial coating machine, you should consider working with either Nordson or GEMA. If you are looking for precision robotic liquid coating machines, then you should be working with either ABB or Sames Kremlin. If you are looking for a supplier that specializes in the production of ceramic LTCC and MLCC materials, then there is no better source than Upper Shell for precision and machine lines tailored specifically for the electronics industry.

By evaluating potential suppliers based on their industry knowledge, custom capabilities, and after-sale support, you will find a partner that will help you reach your business goals and ensure the long-term success of your organization. Investing in a reliable coating system will help improve product quality along with reducing the amount of wasted materials, improving safety, and positioning your business for sustainable growth in an increasingly competitive marketplace.
