Focused Learning

In the last decade, the plastics injection molding industry has become more complex and part and mold designs more complicated. Engineering teams are now expected to understand feature-integrated and intricate part designs that require more complex tooling and molding processes. To avoid costly mistakes and tool re-work, engineers must evaluate and optimize each step in […]

Torsten’s Training Tips: Mechanical Material Behavior

Injection molding is a widespread manufacturing process used to create various everyday items, ranging from pipette tips to car bumpers, using different polymer materials. These parts can be made from either pure, unfilled polymers or those that are enhanced with reinforcements and additives. It’s crucial for designers of these parts to understand the mechanical behaviors […]

Torsten’s Training Tips: Mechanical Material Behavior

Injection molding manufacturing produces many everyday parts, from pipet tips to car bumpers in a variety of polymer materials. Some parts are produced from neat, unfilled materials and some from materials that are filled with reinforcements and additives. Part designers should be able to evaluate the mechanical material behavior and properties of these different polymers […]

Torsten’s Training Tips: Nominal Wall Thickness

What is the “Nominal Wall Thickness,” and how is it relevant in designing functional plastic parts?  Although parts can have various wall thicknesses to accommodate form, fit, and function, designers are generally tasked with minimizing thickness to lessen material consumption, achieve a faster cycle time, and reduce manufacturing costs. Nominal Wall Thickness However, parts with […]

Torsten’s Training Tips: Fill Speed Profiles

Evaluating and understanding fill speed profiles is an essential aspect of injection molding. Polymer materials can flow by heating them to their melting range. Every polymer has a melt and mold temperature range; within that range, the polymers flow and can be injected into a mold. The molten polymer is injected into the mold by […]

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: Jetting

Injection molding polymer through small gates creates complex three-dimensional fluid flow behaviors. Jetting occurs in injection molding when polymer material is injected through a nozzle, runner, or gate at high velocity, into open, thicker areas, without forming contact with the mold wall.  The jetting effect is like water flowing through a hose. If you place your thumb on […]

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 […]
