【Application Examples of Induction Heating】Tip Processing of Catheters / Welding of Injection Needles
Pinpoint accuracy
Induction heating (IH), which heats small areas non-contact and with pinpoint accuracy, is suitable for the precision processing of catheter tips and the welding of injection needles. 【Processing of Catheter Tips】 By forming a rounded tip on the catheter tube, it enables insertion into the human body (minimally invasive surgical treatment) while minimizing tissue damage. The mold for tip processing is made of small stainless steel. By heating the mold, the inserted polyvinyl tube is melted, poured into the mold, and shaped. Precise temperature control is essential to maintain consistent heating and pouring into the mold. An infrared radiation thermometer is used to measure the temperature of the mold, and the signal is fed back to the induction heating power supply to control the heating. 【Welding of SUS Injection Needles to Needle Hubs】 It has been said that heating extremely small objects like injection needles is a weak area for induction heating, but Alonix has overcome this challenge by using a high-frequency amplifier. By applying high frequencies in the MHz range, the injection needle (SUS pipe) is instantaneously heated and welded to the needle hub. *For more details, please download the PDF or feel free to contact us.

Company information
We manufacture and sell high-frequency power supplies and their applications for industrial use and scientific research, including induction heating power supplies, high-frequency power supplies for plasma, and RF power amplifiers. Our induction heating power supplies are available in a wide range from 1.2 kW to 500 kW, and due to their unique compact design and broad frequency range, they are applied in applications where induction heating was previously difficult. For plasma power supplies and RF amplifiers, engineering and manufacturing are conducted at our U.S. subsidiary, and in addition to sales, we also design and manufacture application equipment. With over 30 years of experience in plasma high-frequency power supplies and broadband amplifiers for semiconductor devices, we provide precise engineering services to realize our customers' ideals. We also offer free initial heating tests for equipment selection.
