Radiation therapy plays an important role in fighting tumors. To protect patients from excessive radiation, a reliable protective layer is needed. These protective layers must have the highest accuracy and the quality is absolutely guaranteed. Our refractory metal components have helped tens of thousands of patients undergoing radiation therapy recover. The multi-blade collimator and protective layer components made of tungsten-based high-gravity alloy can accurately target the rays to the diseased tissue. Precise irradiation of tumors to protect healthy tissue. We have a superior level of machining accuracy and expertise, and use molybdenum and tungsten to manufacture parts. With decades of experience, we are able to form and process these materials with the highest precision and to maintain the strictest tolerances.
