Title:
NEEDLE FOR WARP KNITTING MACHINE AND METHOD FOR MANUFACTURING NEEDLE BY MEANS OF AMORPHOUS ALLOY INJECTION MOLDING PROCESS
Document Type and Number:
WIPO Patent Application WO/2023/236719
Kind Code:
A1
Abstract:
A needle for a warp knitting machine, manufactured by means of an amorphous alloy injection molding process and comprising the following components: in parts by weight, 57.5-65.5 parts of zirconium, 11-16 parts of copper, 7-13 parts of nickel, 5-10 parts of titanium, 1-7 parts of aluminum, 1-7 parts of beryllium and 0.3-2 parts of yttrium. A method for manufacturing a needle for a warp knitting machine by means of an amorphous alloy injection molding process, comprising the following steps: (1) material mixing and smelting for manufacture into small blocks; (2) injection molding; (3) alloy opening removal; (4) thickness machining; (5) grooving; (6) polishing; and (7) electroplating. Beryllium and yttrium are added into amorphous alloy zirconium-based metal; beryllium can improve the toughness of a latch needle product, and has high fatigue limit and high wear resistance; yttrium powder can improve the strength, toughness and wear resistance of a latch needle blank.
