Insert Nuts  Manufacturers, Traders, Suppliers

The insert nut is a product that embeds an insert with internal threads and knurled or other patterns on the outside in a plastic or other alloy product (mainly used on plastic products) to form an effective thread on the main product .

All kinds of special inserts for thermoplastic and thermosetting plastic parts are suitable for different application requirements, including hot melt and ultrasonic inserts, in-mold injection inserts and cold press inserts.
Cold pressed series
Cold-pressed inserts are suitable for thermoplastics with medium or low hardness. After the plastic parts are formed, they are directly cold-pressed into the prefabricated plastic holes.
The outstanding advantages of cold press inserts are convenient implantation and high efficiency, but at the expense of torsion and tensile performance. Some cold-pressed inserts can also be implanted by ultrasonic or hot-melt technology to obtain better torque and tensile performance.
Hot melt and ultrasonic series
Hot melt is to press the copper insert into the plastic matrix after heating the product, which can make the product heat quickly and speed up the work efficiency. The heated copper insert can also quickly conduct heat to the plastic part, so that the periphery of the plastic hole becomes soft. So as to quickly press the product into the hole. Due to the embossing process on the outer diameter of the insert, it forms a certain friction and bite force with the copper insert after forming, which can be fixed in the inside so that it cannot fall off. Has a certain torsion and tension.
In-mold injection series
In-mold injection molding inserts are suitable for all plastic materials. Before plastic injection, insert the inserts into the mold inserts and fix them before injecting glue. In-mold injection molding inserts are generally designed with straight patterns, so the cost of the inserts is relatively lower. Forming directly in the mold can obtain the best torque and tensile performance, and allows a smaller wall thickness. The disadvantage is low efficiency.

Insert nuts are widely used in all walks of life, and are commonly used in various plastic casings such as the automotive industry, medical equipment, consumer electronics, mobile phones, and computers.
