HVOF & Thermal Fusing


Discover our exceptional capabilities and expertise in thermal fusing technology.  Each plunger in our collection undergoes a cutting-edge process, where it is coated with High Velocity Oxygen Fuel (HVOF) for enhanced performance. Utilising state-of-the-art robotic technology, the coating is applied at speeds surpassing Mach 2, guaranteeing unparalleled precision. 

To further elevate quality, we employ a metallurgical bonding technique that seamlessly fuses the coating to the base material. Our fusion process ensures a high bond strength and a uniform, dense and porous free coating with the options of a surface hardness of 45HRc to 65HRc.
