Questions Asked in Airset Molding Interview
Q 1. Explain the Airset Molding process in detail.
Airset molding, also known as air-pressure molding or air-assisted molding, is a manufacturing process used to create various parts, primarily from thermoplastic materials. It combines the advantages of both injection molding and blow molding. The process involves injecting molten plastic into a mold cavity under high pressure. Once the cavity is filled, compressed air is introduced to further consolidate the material, ensuring accurate part dimensions and a more uniform wall thickness. This air pressure helps to reduce the required injection pressure and clamping force compared to standard injection molding. Think of it like blowing up a balloon inside a mold – the air pushes the plastic tightly against the mold walls.
The process typically begins with the injection of molten plastic into the mold cavity. Once the plastic reaches a certain level of solidification, compressed air is introduced through a dedicated channel within the mold. This air pressure helps to completely fill the mold cavity, leading to improved part density and reduced sink marks (depressions on the surface of the part). Finally, the mold is opened and the finished part is ejected.
Q 2. What are the advantages and disadvantages of Airset Molding compared to other molding techniques?
