6H Plasitc Threaded Inserts With Good Magnetic And Electrical Conductivity


In general, the screw connection between plastic parts is usually connected by self-tapping screws. The inner hole of the plastic screw column can be formed by injection molding at one time, and the subsequent self-cutting of the self-tapping screw is used to generate the threaded connection, which is convenient and fast; however; When the connection strength between plastic parts needs to be improved, the screw must be tightened with sufficient torque to generate sufficient axial tension between the main part and the screw thread to prevent loosening. However, the inner hole of the plastic screw column If the thread cannot withstand a large enough load, slippage or looseness will occur, which naturally cannot meet the required connection strength.

The metal thread can prevent the thread from deforming under the entire load, so the copper nut can significantly improve the connection strength in the plastic part.

In a nutshell, the applications of inserts mainly have the following uses or characteristics.

(1) Increase the local strength, hardness, rigidity and wear resistance of injection molded products.

(2) Pressing metal inserts such as brass and silver into the injection molded products can make the products meet the requirements of magnetic and electrical conductivity.

(3) Increase the dimensional stability and accuracy of injection molded products.

(4) Reduce plastic consumption.

(5) Satisfy the appearance and play a decorative effect.

Diamond flower: easy knurling curve, shallow knurling, massage control embedding process, not suitable for hot-melt process, good performance in process.
Twill flower: The knurling area and depth of the villain are easy to control, and it has a self-directed function when implanted, and the overall performance of torsion and tension is good.
The knurling standard of Lijingfan hardware implements the DIN82 standard.
The torsion force of the knurling is related to the traction angle: with the angle of the rising value, the tensile force becomes larger and larger; the heating value increases slightly

Several ways of implanting plastic inserts

Hot melt implantation is also called hot pressure implantation. That is, the insert (usually a copper insert) is heated by an electric soldering iron (to 200-250 degrees), the reserved hole wall of the plastic part is heated and becomes soft, and then the insert is pressed at a uniform speed.

Mold implantation is to fix the metal insert on the thimble (PIN needle) in the mold before the injection molded part is molded, and then the injection molding machine closes the mold and injects the glue. After the mold is opened, the insert and the cooled plastic part are integrated.

Directly press in, the insert does not need to be heated, through the unique form of insert, the punch directly presses the insert into the plastic reserved hole, which is generally suitable for thermosetting plastic. The outer circle of the directly pressed insert has a chamfered edge to prevent it from falling out.

Slotting and pressing do not require heating, and it is divided into two types. One is chamfered. The preset plastic hole is pressed by a punch. Due to the open groove at the bottom of the insert, external force acts on the bottom of the hole, and the thread hole diameter becomes smaller. , Form a certain clamping force on the screwed bolt to prevent the insert from falling out. The second is threaded screwing. The shape of the insert has a sharp self-tapping thread. The insert is screwed into the plastic hole by screwing, similar to a threaded bushing.

Which method is better?

Generally speaking, different implantation methods are selected according to different application conditions. Plastic parts with a simple and neat appearance and only one or no more than two inserts are embedded. From the perspective of efficiency, molds are used for implantation. One plastic part is embedded with multiple inserts. Obviously, hot melt implantation is more efficient. Thermosetting plastics cannot be heated, and cold pressing is better. Harder engineering plastics can be pressed in by slotting.
