Injection molding machine’s working principle is similar to the syringe used for injection. It is the process of injecting the plastic into the closed mold cavity with the help of the thrust of the screw (or plunger), and obtaining the products after solidification and shaping. Most of the injection molding machine still uses the resistive heating circle on the market, resistive heating circle is based on the current resistance heating to generate heat, namely when a current flows through a conductor, the obstacles in the current effect on the resistance of the conductor, and electric current to overcome the resistance of the conductor to do work, the electrical energy into heat energy, and through the contact conduction way, Therefore, it is necessary to make the inner wall of the heating ring and the outer wall of the barrel reliable and close contact to transfer heat energy to the barrel.

Here are some points need to to note when using it.
1. Operators and maintenance workers should be required to conscientiously record, count and analyze the faults of injection molding machines, and put forward reasonable suggestions to reduce the incidence of faults.
2. Monitoring instruments are used to monitor the key parts of the injection molding machine in a planned way, and timely find the signs of failure and deterioration information.
3. Training maintenance staff to master the common failure analysis method of injection molding machine.
4. The maintenance personnel or repair team leader should collect the information through the daily inspection and status inspection to obtained the status information and failure signs, as well as the relevant records and analysis data and provide each type of injection molding machine problems timely arrangement of daily maintenance.
