Utilize low-shrinkage materials for parts with tight tolerances.
Avoiding tight tolerance areas around the alignment of the mold halves or moving mold components such as sliders.
Design your parts to avoid tight tolerance in areas prone to warpage or distortion.
Our molder you will hear the thrown about term “Tight Tolerance”, unfortunately that term is a tight loosely. If the process is not performed correctly, tolerance part can lead to loss in performance or even part failure. Knowing how-to safely, and effectively reach our customers exact specifications takes a skilled team and our advanced manufacturing technologies.
Generally speaking tight tolerance parts for injection molding plastic parts is + /- 0.002 inches. Many factors are put into play such as materials, part complexity, and tooling and of course the injection process.Starting with a good part design will ensure tight tolerance repeatability, improved manufacturability Gand reduced costs of your plastic injection molded parts.Size, Geometry and Wall thickness requirements have an impact Thicker walls produce different shrink rates depending on the material, making repeatability sometimes more difficult.advice.
Before manufacturing, address and analyze your parts making sure to fully review either the mold flow analysis and/or Design forManufacturability will help ensure a asuccessful injection molding process and the ability to quickly obtain the close tolerance parts your projects require.
