Three Injection Molding Temperatures

Today we talk about the three main injection molding temperatures and their settings.

1. Barrel temperature in the injection molding temperature

Each material has its own melting temperature range. If the temperature is low, the material will not melt well, and if the temperature is high, it will decompose. Therefore, the appropriate temperature must be selected. However, our injection molding machine temperature control system also has certain differences, so we must learn to watch the rubber head and analyze whether the temperature is appropriate.

There are abnormal noises in the glue, and there are obvious granular particles of incompletely melted materials on the printed materials. When the fluidity is not too good, it means that the temperature is too low and the temperature needs to be increased.

Gluing is very smooth, and the injected material has very good fluidity like water, indicating that the temperature is too high and the temperature needs to be lowered.

The material temperature is very important. If it is too high, it will decompose slightly, which will seriously affect the strength and quality of the product. Therefore, changing the material temperature is generally not considered during production.
