Tool Coatings
Tungsten Carbide, Di-Carb, and Plasma Coating
At Tunco Manufacturing, we provide high-performance tooling coatings that extend the lifespan of tools and improve durability in demanding environments. With over 40 years of experience producing crushed tungsten carbide products, we’ve expanded our capabilities to include carbide coatings, tungsten ceramic coatings, and thermal spray plasma coatings for tools used in high-production industry applications.
Whether you’re looking to coat new tools or recoat existing parts, our team has the knowledge and equipment to deliver custom solutions—even if we didn’t manufacture the original part.
Tunco Tool Coating Options
Tungsten Carbide
Tungsten Carbide (WC) is a chemical compound that combines equal parts tungsten and carbon, making it stronger than steel or titanium. Tungsten carbide measures 90 on the Rockwell “C” scale, which approaches the hardness and durability of natural diamonds. The benefits of a tungsten carbide coating include:
- Improves part performance and wear resistance
- Reduces costs on wearable parts
- Decreases machine downtime for part change-outs
- Allows the freedom to design less expensive or lighter weight materials
In its basic form tungsten carbide is a fine, gray powder that is extremely sharp. Our expertise comes into play when this chemical compound is transformed into a form that can then be placed on cutting, sanding and grinding tools. We do this by utilizing a brazing process with a controlled atmosphere furnace to permanently bond the compound particles (grit) to the metal tool part.
Di-Carb
The Di-Carb coating is a Tunco original that uses patented technology to combine the durability of natural diamonds with the extreme sharpness of tungsten carbide. This creates a diamond-like coating for a fraction of the cost. The Di-Carb technology is specifically designed for use with cutting tools. This material is designed to create a long-lasting, rapid cutting saw blade for high-production applications.
Plasma Coating
Plasma coating is a thermal spraying system used to coat metal tools, capable of coating metal sizes from 1/16” to 65”, operating at 35,000 degrees Fahrenheit. We specialize in providing plasma coating that ranges from 400 mesh to 60 mesh with materials such as carbide, ceramic, stainless steel, and aluminum oxides.
Benefits of Plasma Coating include:
- Protects from corrosion
- Wide selection of coating options
- Wear-and-tear resistance
- Heat-resistant
- Applicable to a wide range of materials
The Importance of Tool Coatings
When selecting a tool coating, it’s essential to match the coating properties to the specific demands of your application. Factors such as surface hardness, heat resistance, corrosion protection, and abrasion resistance all play a critical role in determining how well your tools will perform and how long they’ll last in the field.
The right coating can reduce downtime, minimize wear, and improve the efficiency of your equipment. Whether you’re working with abrasive materials, high heat, or corrosive environments, our engineers can guide you to a solution that offers the best performance and return on investment. We offer several industry-leading tool coating technologies designed to meet the needs of high-production and heavy-duty applications.
