1) Material: Steel from KOBE STEEL LTd (Japan);
2) Ultimate tensile strength: 65-75 kg / mm2;
3) Wire diameter tolerances: +0.01 mm;
4) Hardness: 88 HRB (according to ROCKWELL)
5) Electroplating: chrome plating;
6) Surface cleanliness is achieved by chemical etching.
ORGAN NEEDLES always meet the following requirements:
- The exact correspondence of the sizes of the diameters of punctures and sewing needles is strictly observed. (If the diameter of the punctures is larger than required, it will be impossible to ensure the formation of a loop when lifting the sewing needle from the punched hole.)
- The hook needles have a perfectly made crochet hook that grips the loop securely when pulling it out and easily sheds it when needed.
- All parts have a flawless surface finish, which can reduce friction when in contact with paper.
- Needles and punctures, having high strength, at the same time remain brittle enough so that in case of accidental collision with a hard object, the needles will break, but not bend.
