Feilinnsprøyting

Feilinnsprøyting, also known as injection molding of faulty parts or defective part injection molding, refers to a manufacturing process where a mold is intentionally designed or used to produce plastic parts with pre-determined defects. This technique is not about creating unusable products but rather for specific research, testing, or educational purposes.

The primary application of feilinnsprøyting is in the field of materials science and polymer engineering. Researchers use it to study the behavior of plastics under various stress conditions or to investigate the impact of specific flaws on the mechanical properties of a part. By introducing controlled defects, such as cracks, voids, or inclusions, scientists can gain a deeper understanding of material failure mechanisms and develop more robust materials and designs.

Another significant use is in quality control and inspection training. Training personnel can practice identifying and analyzing common molding defects by working with parts produced through feilinnsprøyting. This hands-on experience helps them develop the necessary skills to detect flaws in real-world production scenarios, thereby improving overall product quality.

The process involves modifying existing injection molds or creating specialized molds with features designed to induce defects during the injection molding cycle. These modifications can range from altering gate designs to incorporating intentional imperfections within the mold cavity itself. The types of defects created can be varied, including sink marks, weld lines, short shots, and warpage, each serving a distinct purpose in the experiment or training.
