What is hot tip?

"Hot Tip" in hot runner system refers specifically to the key component in the hot tip hot runner system - the insert at the front end of the nozzle. This insert is combined with the cooling system to accurately adjust and control the plastic molding processing temperature at the gate, thereby ensuring the high-quality production of plastic parts. The following is a detailed analysis of "Hot Tip":

1. Components and working principle

Components: The hot tip hot runner system is mainly composed of nozzles, Hot Tips (hot tip inserts), cooling systems, etc. As a key component, the shape and size of the Hot Tip may vary from manufacturer to manufacturer, but the working principle is the same.

Working principle: Through the synergy of the Hot Tip and the cooling system, the temperature of the plastic at the gate is precisely controlled. This control is essential to prevent the plastic from solidifying prematurely or over-melting at the gate, thereby ensuring that the plastic can be smoothly filled and form a good part surface.

2. Application scope and advantages

Application scope: The hot tip hot runner system can be widely used in processing most crystalline and non-crystalline plastics, such as PP, PE, PS, LCP, PA, PET, etc. It is particularly suitable for the processing of small and medium-sized parts, especially the processing of tiny parts.

Advantages:

Improve production efficiency: Reduce downtime and scrap rate in the production process through precise temperature control.

Improve part quality: Reduce gate marks and improve the appearance and quality of part surface.

Flexibility: The gate size and shape can be adjusted according to different production needs.
