Knurled Nut PM Sintered Part

Product Introduction

Product advantages

There are two forming methods for the knurling of the outer pattern of the knurled copper nut. One is to use copper raw materials to form the pattern, and then produce it on the equipment. Generally, the pattern of the pattern is a straight line. Light round copper material tapping embossing, this processing method can produce some non-standard size knurled copper nuts, such as straight pattern, twill pattern, net pattern, eight-character embossing, herringbone embossing, etc.

Knurled Copper Nut Knurling pattern is a metalworking process that distributes the required tooth pattern on the outside of the nut insert. The knurling pattern on the outside of the insert is critical and directly affects the torsional pull and torque of the nut. , vertical knurling can provide the maximum torque, but the pulling force is small, the value of the groove between the knurling bands increases the pulling force, and the diagonal or spiral knurling balances the resistance in two directions, that is, balances the pulling force and torque performance.

The knurling of the knurled copper nut is simple, and the high-speed automatic lathe can complete it at one time. Complex copper nuts are processed with forming knives and post-processing on table turning/tapping machines. Many products are relatively simple mesh copper nuts and Straight grain copper nut, made of C3604, cut brass, the surface pattern is drawn directly from the original bar, the pattern is full, the tooth peaks and bottoms are clearly visible, and can withstand greater torque after injection molding.

The shape of knurled nuts has different patterns, including straight lines, reticulated lines, twill lines, hexagonal lines, etc., and there are through holes and blind holes. The materials are copper, iron, aluminum, stainless steel, etc. Some copper nuts are drawn. Yes, some are embossed, depending on the application scenarios, they are mainly used for injection molding, metal springs, metal stamping parts, fasteners and other hardware products, all of which are nuts.

Knurled nuts are suitable for all plastic materials. Before the plastic is injected, insert the insert into the mold pin and fix it before injecting the glue. In-mold injection molding inserts are generally designed as straight patterns, so the cost of the insert is relatively lower. In-mold molding can obtain the best torsion and tensile properties, and allows smaller wall thickness, and is widely used in various plastic casings such as auto parts, medical equipment, aerospace, electrical and electronics, mobile phones, TVs, and computers.

Qinhuangdao Zhongwei Precision Machine Parts Co., Ltd. is a modern enterprise engaged in the R&D, production and sales of various precision powder metallurgy parts, specializing in the production of various injection nuts, embedded nuts, hot-melt nuts, embedded nuts, knurled Copper nuts, positioning pins, non-standard nuts, non-standard gaskets, bushings and other precision turned parts are widely used in auto parts, aerospace, medical instruments, electronic appliances, electrical equipment, instrumentation, communication equipment and other industries.
