The Benefits of Moldflow analysis for plasitc injection mould Apr 06, 2018

The application of moldflow analysis in injection-molded plastic parts is now fundamental in part structural design and molding process optimization. Injection molding analysis is capable of simulating the filling, packing, and cooling processes as well as the part warpage after ejection.

Save Time & Money

With previous technology, prior to mold flow analysis software, there was an expensive and time consuming risk of creating a mold tool that might contain a flaw that wouldn’t be detected during the design stage. With mold flow analysis software, part designs can be immediately analyzed before a mold is made. This allows for detailed flaw detection that can save time and money in later stages of a project.

This type of software has the ability to find quality issues relating to flow lines, deep undercuts, weld lines, poor draft angles, warpage marks, and sink marks. When these types of flaws are discovered, design changes can be made immediately in order to avoid costly and time consuming errors.

Applicable To New & Existing Plastic Part Designs

In plastic part engineering, mold flow analysis software is incredibly useful for use with new 3D part designs that contain complex shapes and angles. One of its additional benefits is its usefulness with existing part designs. Simple part designs like round lids can be analyzed for quality, thickness, and other elements that can compromise a finished product.

Understanding Molding Machine Requirements

Machine sizes can vary greatly, so understanding and being able to predict the size of a machine prior to designing parts can save time and money. This allows the costs of parts to be calculated in advance, which is especially useful when working with larger machine parts. Additionally, there is an added benefit to understanding costs and requirements in terms of machine planning and scheduling.

Because moldflow analysis identifies and mitigates potential problems related to these parameters before the mold is constructed, it reduces risk, improves quality and lowers overall production costs. With all of these benefits, you may be tempted to run moldflow analysis on all projects. However, in the case of extremely simple parts made from common materials, moldflow analysis may not be required or even be very beneficial. But, most projects with complex, high-tolerance parts that require precise dimensional stability are ideal for moldflow analysis and will realize the greatest advantage.
