Training Tip: The Five Stages of DOE
Design of Experiments, or DOE, is a powerful mathematical tool that can be successfully applied to areas of new mold trials and to trouble-shoot potentially challenging processes. Experimental design techniques can be utilized by anyone with a fundamental understanding of injection molding. There are five primary stages for conducting a designed experiment. These are planning, […]
Torsten’s Training Tip: Mold Functionality
An important step in the molding process is preparing the mold for optimal functionality. Every plastic injection mold is unique and requires a tailored set-up strategy. There are several important steps to take prior to beginning the molding process development phase. These include setting up and checking the functionality of the following: Molding machine Mold Ejector […]
Torsten’s Training Tip: Understanding Flow-Induced Molded-In Stress
Injection molding is a complex manufacturing process involving temperature and pressure. During the molding process polymer materials experience complex molecular chain deformation while undergoing temperature and pressure changes. Molded part properties and performance are dependent on, and influenced by, design complexity and the molding process. Understanding molded-in stress, specifically flow induced molded-in stress, is an […]
New Training Topics Coming Soon
At Kruse Training we pride ourselves on the ability to consistently add new content and topics that meet the needs of the injection molding industry. With this in mind, we are currently undertaking a series of new topics focusing on areas that move beyond the basics of injection molding to the more complex aspects of […]
Torsten’s Training Tip: Gate Seal Time
Gate seal time is an important aspect of the packing phase that needs to be understood to produce high quality molded parts. Setting proper gate seal time plays a key role in packing parts. Properly packed parts will have even internal polymer molecular structure, fewer volumetric shrinkage differences, optimized part dimensions, and fewer sink marks […]
