Applications and Development Prospect of Tzm Internal Heating Hot Runner System

Hot runner system is divided into internal and external heated hot runner system, hot runner system TZM internal heating hot runner system due to its significant advantages has been widely used in the following areas:
1. High quality plastic parts forming complex. TZM internal heating hot runner system can provide accurate and stable temperature control, runner plate and nozzle external temperature have little impact on molding, is extremely advantageous to the quality of the plastic forming parts, such as plastic shape lifelike, high dimensional accuracy.
2. Small plastic molding. Low voltage with internal hot runner system can implement uniform heating and accurate temperature control, to achieve a small nozzle spacing, can inject weight small plastic parts, such as microelectronics, small mechanical parts and other products.
3. Decorative pieces of plastic parts. Some plastic pieces of the expensive are cover printing, puts the diaphragm of the printing before injection mould, also known as a mould decoration. Using internal heating hot runner system can well meet the requirements of decorative pieces of plastic parts..
4. The high temperature plastic injection. Hot runner system high temperature engineering plastics injection, melt temperature as high as 300 ~ 400 ℃, and the several degrees temperature fluctuations is only allowed. TZM internal heating hot runner system well solved the problem of the leakage and heat loss, and to provide stable and uniform heating, make the flow passage of the temperature fluctuation is small.
