Up to 20-25% regrind is standard in many applications, but thermal degradation and contamination risk increase with every cycle. Here's how to set limits for your material.
AI-Cortex analyzes part geometry, material data, and process parameters to predict fill, weld lines, and sink marks before the first shot. Here's how the prediction engine works.
Flexible materials are not interchangeable. TPE offers low-cost flexibility; TPU brings abrasion resistance and chemical compatibility. Learn how to choose between them.
Underdried resin causes silver streaks, hydrolysis, and structural failure. This article provides drying specs for PET, ABS, PA, PC, and PBT with decision tables.
Polypropylene is semi-crystalline and anisotropic. Warpage isn't random — it's driven by crystallization kinetics and fiber orientation. This article explains the mechanism.
Glass fibers break during plasticization and injection. Broken fibers mean weaker parts and more wear on your screw and barrel. Here's how to minimize the damage.
PA6 and PA66 look similar on spec sheets but behave very differently in production. We compare moisture absorption, weld line strength, and cost to help you pick the right grade.
You don't need a materials science degree to use viscosity curves. This practical guide explains shear thinning, viscosity at injection, and how to use the data on the shop floor.
The pack and hold phase is the most over-looked step in the molding cycle. Incorrect hold pressure leads to overpacking, flash, and residual stress.
Gate design affects fill pattern, weld line location, and cosmetic quality. This article compares the three most common gate styles with real-world geometry examples.
Design of Experiments in injection molding lets you systematically find the robust process window. Learn the 5-step DOE methodology used by world-class molders.
