Injection needles, fish hooks, sewing needles
Needles are used in a variety of fields, from medical use to hobbies, such as medical injection needles, acupuncture needles, sewing needles, fishing hooks, etc., and the common requirement is the strength of the needles.
”Quenching" is a manufacturing process necessary to maintain the strength of needles.
Needle manufacturers have their own know-how on quenching, and we precisely apply this know-how to IH to improve the yield rate.
Advantages of IH
- Meets tight production tolerances with precise localized heat to small areas creating pinpoint accuracy
- Increased production rates with faster heating cycles
- Non-contact heating: Hygienic and suitable for medical use
- Environmentally friendly – creates clean, pleasant operating environment
For welding injection needles
IH can be used not only for quenching needles but also for welding injection needles to needle hubs.
Ultra-thin injection needles (SUS pipes) are instantly heated and welded to needle hubs.
Induction heating enables non-contact and highly reproducible heating in a short time.
