JX-21JG255-M4-D11-7.85-B, Ultrasonic equipment for brass knurled nuts

Name: Threaded Through-Hole Knobs

Material: Stainless steel.Carbon steel.Brass

Size: M2, M3, M4, M5, M6, M8, M10, M12&Inch4-40, 6-32, 8-32, 10-32, 1/4-20", 5/16-18", 3/8-16", 1/2-13.

Long shafts can thread through these knobs for mounting versatility. The knobs provide a secure grip to position, tighten, and hold fixtures, equipment, and machinery.

1. Steel knobs are stronger than iron. Those with a black-oxide finish have mild rust resistance.

2. Stainless steel knobs have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.

3. Aluminum knobs have mild corrosion resistance, are lightweight, and are non-magnetic. Brass knobs have good corrosion resistance and are non-magnetic.Brass nuts, also known as pre-built nuts and inlaid copper nuts or plastic buried nuts, according to the use of different methods are divided into hot melt copper nuts, hot pressed copper nuts, embedded copper nuts, and ultrasonic copper nuts. Copper nuts are widely used in cell phone shells/pencil book shells/injection molding parts/plastic parts of embedded parts, as a female thread use. Generally embossed with an outer circle. To prevent sliding. Our factory specializes in producing all kinds of copper nuts. And widely used in various injection molding industries.

Injection-molded brass nuts can also be understood as inlaid brass nuts or embedded brass nuts, in the market there are different injection-molded brass nuts, and their use also varies.

Its operation principle: the main use of copper insert is to inject the product inside some plastic parts after installation can form an effective internal thread in the plastic parts. This is done by heating the product and inserting it into the plastic part or by direct injection in the mold. Because brass has good thermal conductivity, pressing the brass insert into the plastic substrate after heating can make the product heat up quickly and speed up the work efficiency, and the heated brass insert can also transfer heat to the plastic part quickly, which can make the plastic hole surrounding soft so that the product can be pressed into the hole quickly. If mold injection is used, the copper insert can be heat injected into the plastic part because of the embossing process on the outside diameter, and the copper insert forms a certain friction and bite force after forming, which can make it fixed inside so that it cannot fall off.

Application: The products are widely used in cell phones, portable computers, many kinds of plastic shells, communication, micro-motor, computer, electrical appliances, electronics, toys, clocks and watches, lighting, locomotive, and other industries.

Type Mainly: CNC computer turning parts, cell phone nuts, embossed nuts, hot melt nuts, hot pressing nuts, buried nuts, ultrasonic nuts, injection nuts, insert nuts, copper shafts, copper columns, copper bushings, copper cups, precision shafts, and non-standard screw nuts and other twenty categories, tens of thousands of specifications.
