What is warpage in Moldflow?
Moldflow warpage simulation. Warpage in an injection molded part is caused by shrinkage variations throughout the part. Shrinkage of plastic part is driven by the volumetric change of material as it cools down from the melt state to solid. It must be noted that shrinkage itself does not cause warpage.
How do you prevent warpage in Moldflow?
Remedies
- Minimize differential shrinkage.
- Minimize orientation effects. Position gates for unidirectional flow, and modify part thickness.
- Change the part geometry. Add features such as stiffening ribs to the design.
- Use thinner wall sections with ribs.
- Change the material.
What is Warp analysis?
A Warp analysis is used to diagnose the cause of warping and recommend a solution, such as gate location changes, design parameter changes, or reduction of wall thickness variations. Warp analysis is supported for Dual Domain and 3D analysis technologies. Warpage is affected greatly by fiber orientation.
What is Moldflow Adviser?
Autodesk Moldflow Adviser is the small and cost-effective solution for simulating the design during component development. With the resulting digital prototypes, development times and costs can be drastically reduced.
What is the difference between shrinkage and warpage?
Shrinkage is defined as a change in size. Warpage is a change in shape.
What does warpage mean?
noun. mass noun. The extent or result of being bent or twisted out of shape, typically as a result of the effects of heat or damp. ‘the warpage of the wood increased as the temperature increased’
What is the difference between Moldflow Adviser and insight?
Moldflow has two core products: Moldflow Adviser which provides manufacturability guidance and directional feedback for standard part and mold design, and Moldflow Insight which provides definitive results for flow, cooling, and warpage along with support for specialized molding processes.
What is plastic warpage?
Warpage in plastic injection molding is when the intended shape of the molded part is distorted during the cooling process. Mold warping can cause the part to fold, bend, twist or bow.
How is warpage measured?
Warpage is generally measured by detecting a target at three points. Measurement is also possible by moving a target with a point-type sensor, or by directly measuring the shape by projecting a laser in a horizontal line.
How do you check a cylinder head for warpage?
Measure up and down the length of the head and record the thickest feeler gauge blade that passed through the gap. Write that number down. Perform the exact same procedure on the other side of the head. Write down the thickest blade measurement that passed under the straight edge.
What is the warpage analysis for in injection molding?
Warp analysis is supported for Midplane,Dual Domain and 3D analysis technologies. Warpage is affected greatly by fiber orientation. Warpage in an injection molded part is caused by variations in shrinkage that occur:
What is mold flow analysis (MFA)?
What is Mold Flow Analysis? Mold Flow Analysis (MFA) is a software that is used to simulate the flow of molten plastic material into the injection mold crate, allowing the manufacturer to elevate mold and part design in order to create products that are of the highest quality.
What is base&cover Moldflow analysis report?

What is a mold flow?
These steps don’t have to be identical, but they do follow a certain protocol that ensures the goal is attained with the lowest energy consumption and raw material wastage. This process from the start to the end is what is called the mold flow.
