In order to meet the needs of installation and connection, or to increase the strength of the plastic part, suitable metal parts are designed to insert into plastic molding parts, making an integrated products of both metal and plastic.
The connector is designed with brass insert, it is a good insulator with better strength, so it is applied for electronic and electrical power components, machinery and equipment installation.
This mold is multi-cavities 1*2. The insert positioning block for the copper can be taken out and put in easily from the cavities. The brass insert was preheated to ensure a uniform temperature in the mold cavities.

Plastic molding part with metal material insert provides you additional functions, you can obtain great advantages including:
It is of electric conduction with brass insert for electronic devices electrical equipment.
To design with screw thread section on the metal, it can be installed to devices and equipment very conveniently.
With metal insert, it enhances the strength of the plastic molding connector.
It is of electrical insulation and heat insulation for safety sake.
With low-level noise.
Select metal materials with a small coefficient of thermal expansion as inlay materials, such as brass, aluminum, aluminum alloy, etc.
The metal design shall not have sharp corners, and shall be properly rounded to improve the plastic strength. The surface of the insert should preferably be provided with exquisite rolling patterns or grooves to increase the friction.
The plastic thickness around the metal insert shall be sufficient. For example, the plastic thickness around the insert is "h", the outer diameter of the metal insert is "D", the plastic thickness for the aluminum insert should be h ≥ 0.8D, and the plastic thickness for the brass insert should be h ≥ 0.9D.
