Leading Swedish manufacturer of premium stainless steel fasteners BUMAX has won an initial order from a medical equipment customer for 17,000 ultra premium screws for the manufacturing of a new model of proton cancer therapy machine.
BUMAX was the only supplier able to provide screws that meet the ‘CERN 507 standard’, which is essential for fastening the vacuum parts of this new type of proton cancer therapy machine. CERN 507 is a new standard for ultra-high vacuum applications for magnetic field strength stainless steel. BUMAX developed the standard together with CERN (the European Organisation for Nuclear Research).
Proton therapy machines are a major advancement in the fight against increasing cancer rates around the world as they accurately deliver proton beams to precisely where they are required.
Low magnetic permeability essential
This particular, yet unnamed, customer required a high strength stainless steel screw with low magnetic permeability that met the CERN 507 standard to fasten all vacuum parts on its new model proton machine to avoid vacuum leakages and ultimately machine failure. Low magnetic permeability is essential for proton machines to not interfere with the movement of protons.
“Our customer found that BUMAX was the only fastener supplier in the world that was able to manufacture screws to CERN 507 standard. BUMAX was able to fully meet the customer’s requirements by offering high-strength low magnetic permeability BUMAX 109 screws with silver coating,” says Camille Feuillet, business development manager at BUMAX.
“CERN 507 has huge potential to benefit various advanced manufacturing and high-tech industry applications, not merely medical equipment. We anticipate supplying our premium high strength fasteners to many more customers in the future,” said Patrik Lundström Törnquist, managing director of BUMAX.
