Sistem pelari panas harus memberi perhatian kepada masalah tekanan suntikan

Pelanggan mungkin tidak begitu berhati-hati dengan penggunaan sistem hot runner. Hari ini, JasonMould ingin bercakap dengan anda mengenai tekanan suntikan semasa memilih sistem pelari panas.

Kehilangan tekanan suntikan dalam sistem pelari panas tidak dapat diabaikan.
Ramai pengguna acuan pelari panas mempunyai kesalahpahaman bahawa penyelesaian plastik dalam pelari panas selalu panas, jadi kehilangan tekanan suntikan pelari panas jauh lebih kecil daripada pelari sejuk.

Sebenarnya, in order to adapt to the needs of hot runner structure design, the flow distance of the solution in the hot runner system will be greatly increased, so the injection pressure loss in the hot runner system cannot be seen.
In practical applications, the injection pressure loss in the hot runner system is too large, which makes the injection molding difficult. Oleh itu, the flow distance of the plastic (seperti PC, POM, dan lain-lain.) and the solution in the hot runner system is poor.
besar, heavy parts, dan lain-lain., should use CAE software for flow analysis.

After the production of the hot runner injection mold is completed, the shutdown operation of the injection machine is used, and the following operations must be performed:

Pertama, turn off the heater of the hot runner system.

Kedua, turn off the cooling system of the mold.
For heated hot runner systems, the mold cooling system must be turned off after the temperature has dropped to 80 °C.

Before the end of the hot runner injection mold production, for high temperature plastics and heat sensitive plastics, refueling must be carried out.
For some plastics such as PCs, it can stay in the hot runner system and the barrel of the injection machine.
At a low temperature of about 160 °C, the injection can be interrupted for up to 12 Jam, but it cannot be interrupted for a long time.
Thermal plastics cannot interrupt the injection.
In the barrel of the injection machine and in the flow path of the hot runner, there is a strong adhesion between the cured or semi-cured plastic and the metal surface, even separating the nitride layer.
The screw of the injection machine and the pin of the switch nozzle have a surface nitride layer. Oleh itu, do not interrupt the injection and perform the melt cleaning before shutting down.
