At Engineered Performance Coatings (EPC), we provide specialized surface coating services to protect your components against wear, corrosion, and high temperatures. As your production volumes increase or internal processes demand closer control, bringing your coating operations in-house can be a practical next step.
As part of the STS Group, EPC USA also supplies thermal spray equipment from Flame Spray Technologies (FST). FST is an established manufacturer of reliable thermal spray equipment, ranging from individual systems to complete production lines. This direct connection within the STS Group gives EPC customers access to proven equipment and extensive thermal spray expertise when setting up or expanding their in-house coating capabilities.

Thermal Spray Systems by FST
FST develops modular thermal spray systems that can be tailored to your specific production requirements. These platforms are designed for process reliability, precise control, and practical expansion.
1. HVOF Thermal Spray Systems
High-Velocity Oxygen Fuel (HVOF) technology is widely used for dense, hard wear coatings. FST supplies HVOF coating equipment for both gas and liquid fuel operations.
- Each HVOF coating machine includes precise mass flow control for consistent operation.
- For industrial applications, this HVOF spray equipment and integrated HVOF thermal spray equipment ensure reliable bond strength and low porosity.
