injectdruck

Injectdruck, also known as injection pressure, refers to the force applied to propel a material, typically a fluid or semi-fluid, into a mold or cavity during an injection molding process. This pressure is a critical parameter that influences the quality and integrity of the molded part. It must be sufficient to overcome the resistance of the mold and ensure the material completely fills the cavity.

The injectdruck is generated by a hydraulic or electric drive system within the injection molding machine. It is measured in units like Pascals (Pa), megapascals (MPa), or pounds per square inch (psi). The specific pressure required varies greatly depending on factors such as the type of material being injected, the viscosity of the material, the geometry and size of the mold cavity, and the desired wall thickness of the final product.

Insufficient injectdruck can lead to incomplete filling of the mold, resulting in short shots or voids in the part. Conversely, excessively high injectdruck can cause problems such as flash, where material squeezes out between the mold halves, or excessive stress on the mold and the molded part, potentially leading to defects or damage. Precise control of injectdruck is therefore essential for achieving consistent and high-quality molded components.
