Customer case story: Cancer treatment equipment

BUMAX is currently the only the only supplier that can deliver screws that meet the CERN 507 standard, which is required to ensure the proper fastening of the vacuum parts in a new proton cancer therapy machine model.

The cancer treatment equipment manufacturer needed a stainless steel screw with high strength and low magnetic permeability that met the CERN 507 standard on its latest proton machine. Standard strews that do not meet the standard can lead to leaks and even equipment malfunction.

BUMAX was able to meet all the customer’s criteria regarding strength and magnetic permeability. In addition, BUMAX premium screws are not affected by galling issues.
