The Process Difference -- Cast Iron Applications

Cast iron products have unique requirements for how they are coated and fired. For example, the high heat necessary to bond porcelain to a cast iron substrate can result in product distortions during the firing process.  Tooling designs that keep the forces of gravity and high heat at bay are necessary.

In addition to the process steps described here for cast metal products, Porcelain Industries offers full-service product design consultation - so that the product you are planning to produce can be cost-effectively coated without modifications.

Our Specialty: Special Needs
To successfully coat your cast metal product, we apply a series of steps to the process that is unique to our industry. Achieving a long-lasting, durable porcelain finish on cast products is one of our specialties. What's most special about it is the attention to detail we bring to the table - so that the product you envision meets the needs of your customers for fit and function.
