Johnson Matthey recently completed a major expansion and five-fold increase in volume capacity for fine-hole micromachining of medical component parts. Using advanced micro-machining technology, these component parts actually exceed precision micro demands of the medical device industry.
The San Diego, Calif.-based firm hopes the increased capacity improves its ability to machine intersecting or cross-holes in various configurations. The complex array of fine holes is used for advanced medical applications such as electrophysiology catheters with irrigated tips. The fine holes facilitate uniform cooling during procedures. Other unique uses are emerging as medical device companies begin to take advantage of this advanced machining technology, company officials said.
Johnson Matthey machines holes as small as 0.003" diameters without burrs or other imperfections, while producing an extremely high yield that helps to reduce waste and provide the most value to OEM customers, according to the company. Officials said the company had the capability to produce surface finishes down to 5 microns, and eliminates or minimizes random tool marks, dings and dents, and there is no foreign material visible at a 10-times magnification.
Customer requirements for very precise, small parts are increasing in demand and complexity.
According to General Manager Brian Woodward, "Our continued investment in technology and innovation is providing enhanced capabilities that meet the supply chain expectations and high quality standards of the medical device industry."
Johnson Matthey provides Platinum Group Metals and Nitinol for use by medical device manufacturing facilities. Raw materials, precious metal tube and wire manufacturing originate in the company's West Chester, Pa., facility as well as its facility in the United Kingdom. Nitinol tube, wire, sheet and machined parts are manufactured in the San Jose, Calif., plant and micromachining operations take place in San Diego.
