-Jose Gaonkar, Mechanical Engineer at Cadila Pharmaceuticals
The heat sink was marvelous, within the critical tolerance, and the surface finish was excellent. The fan position, seal, and fin structure all performed as intended. I'll tell my friends and other electronics companies about your service.
I appreciate your exceptional communication and CNC-Machining service.
-Blake Henderson, Product Designer at MechaTronix,
I needed a quick prototype for my research, but I had no idea that their CNC machines were so sophisticated and could produce it in just three days. The prototype was quite precise and fell within the tolerances of the CAD I provided.
Thumbs up! Not just selling, nothing else count for them; Service ServiceService, first!
-Jason Barrett, Individual Mechanical Engineer
Prolean has been manufacturing numerous customized components for my metal-workshop machines for the past two years, and I have found that they are excellent with their CNC machining services.
I am delighted with the level of quality they offer and the precision of the customized machine parts.
