How does a closed plastic impeller mold work?

3D model of a closed plastic impeller. Closed-type plastic impeller molding is done through the mechanical pressure generated by a hydraulic press to make the concave and convex mold close the mold, thus pressing the plastic material into the required shape.

What are the advantages of molding a closed plastic impeller?

As one of the main molding processes of the closed plastic impeller, molding has the advantages of simpler mold structure, better dimensional accuracy, and surface smoothness compared with injection molding 2.

Which raw material is used in closed plastic impeller molding?

The main component of the plastic raw material used in the closed plastic impeller is UTR9000, whose melting point is generally about 170 °C and the decomposition temperature is about 260 °C. The closed plastic impeller molding mainly relies on the UTR9000 material becoming molten.

What is closed-type plastic impeller molding?

The closed-type plastic impeller molding process is to heat the mold to a certain temperature and then add the preheated plastic material through the charging chamber.

How to calculate pressure of closed plastic impeller molding?

Substituting Eq. ( 14) into Eq. ( 13 ), the equation for calculating the pressure of closed plastic impeller molding can be obtained, as shown in Eq. ( 15 ): $$ P_ {z} = P_ {0} e^ { { - \frac {Z} { {Z_ {0} }}}} $$

Why do plastic impellers need to be heated?

The proper temperature not only heats the plastic material faster with quality assurance, but also reduces the pressing time of the closed plastic impeller, making the production process compact and efficient.
