Component Thickness for Mold Flow Analysis

V. Mold Flow Analysis

For some mold manufacturers, the first thing that goes out the window for fluid-based manufacturing, like plastic injection molding, is an accurate prediction of fluid flow in the mold. However, for TDL, the intricacies of the mold that significantly impact the fluid flow are carefully considered during the mold flow analysis.

This stage is critical to the success of the mold manufacturing process as it ensures that the plastic product is not hindered in the mold while in its molten state. It is where TDL’s understanding of flow dynamics comes in handy to handle uncommon and unforeseen challenges that might play out during mold production.

Crucial aspects of the mold, such as the mold wall thickness, layout, and material engravings, are addressed to ensure the mold’s optimal performance.

Starting with component thickness, ensuring the right thickness goes beyond just taking measurements. This parameter is responsible for obtaining optimal results, including making necessary calculations while understanding the behavior of materials during the injection molding process. TDL counts on understanding this fluid flow and its analysis as the cornerstone to delivering an impeccable door handle cover mold.  

For TDL, every contour and every engraving is a conscious but careful decision made with the accuracy that describes their duty to excellence. The overarching goal of defect-free and satisfying mold manufacturing is the ball they are never going to drop.
