(a) green sand moulding
(b) dry sand moulding
(c) pressure moulding
(d) machine moulding
Ans: (c) pressure moulding
The technology has originated in sealing of harness in the automotive industry - today it is used to protect electrical and electronic components in many fields.
With 5-40 bars, the production process takes place at a much lower pressure than the traditional injection molding method. This makes it possible to easily mold even delicate components like PCBs, sensors, etc. directly.
The cycle time is reduced in the molding process, which takes about 10–60 seconds, depending on the size and shape of the components. Later, a direct forward process is possible, which is an important advantage in saving compared to time. 2-component casting.
By optimizing the material flow, molding with the thermoplastic used can also be realized for temperature-sensitive components.
Different material properties and processing versions, combinations of different materials and possibly further process steps enable a wide range of applications.
