Large wall thickness DFM check

Large wall thickness issue in molding design analysis refers to the challenge of molding features with overly thick walls. This can lead to difficulties such as uneven cooling, excessive material usage, and potential defects like voids or surface blemishes.

The root causes typically involve inadequate cooling time, excessive injection pressure, or suboptimal material selection. Therefore, it is recommended to maintain wall thicknesses of 4.0 mm or less to prevent potential material flow problems and prolonged cooling times.

Large wall thickness detection conditions

MTK identifies this issue when the following condition is met:

where:

• $D$ — distance between two faces
• $D_{max}$ — maximal expected distance

How MTK detects large wall thicknesses

MTK automatically analyzes B-Rep CAD models for large wall thicknesses. The SDK checks the relevant geometry against DFM criteria to identify potential issues that can increase manufacturing complexity or cost, or lead to quality or assembly problems.
