Knurled copper nut
Knurled hot-melt copper nuts are mainly used for metal springs, special-shaped springs, craft gift springs, battery springs, spring antennas, key rings, phosphor bronze springs CNC automatic lathe turning parts (copper car parts, iron car parts, aluminum car parts) , Metal stamping parts, electronic hardware, iron shafts, single flower shafts, multiple flower shafts, iron pins, non-standard screw nuts, connectors, fasteners, wire forming (metal wire business card holder, model aircraft landing gear, S hook , R-type bolt, triangle buckle, D-type buckle) and other hardware products, belong to the copper nut series.
1. It can tolerate less fleshy design.
2. It can be quickly embedded using hot-melt copper nuts or ultrasonic methods.
3. The design of round head guide has good positioning effect; it is not easy to be skewed.
4. Staged outer diameter design, gradual injection of plastic; base material plastic is not easy to burst.
5. The double diagonal pattern design in the opposite direction, combined with plastic precisely, has strong torsion force.
Injection-molded hot-melt copper nuts can also be understood as inlaid copper nuts or embedded copper nuts. Different injection-molded copper nuts appear on the market, and their uses are also different.
How it works
The main purpose of the copper insert is to inject the product into some plastic parts, which can form an effective internal thread in the plastic part after installation. The method of operation is to heat the product and embed it in the plastic part or directly use the mold for injection. Because brass has good thermal conductivity, pressing the copper insert into the plastic matrix after heating can quickly heat up the product and speed up work efficiency. The heated copper insert can also quickly conduct heat to the plastic part, thereby making the plastic The periphery of the hole becomes soft, thereby quickly pressing the product into the hole. If mold injection is used, after the copper insert is heat-injected into the plastic part, due to the embossing process on the outer diameter, it will form a certain friction and bite force with the copper insert after forming, which can make it fixed inside so that it cannot fall off.
