Injection Molding Tolerances: 3 Things Engineers Must Know

Jan 19, 2022·Simply put, the larger the part's dimension, the harder it is to control shrinkage and manage injection molding tolerances. 2. Pay Attention to Complexity. When done correctly, a complex design can aid in maintaining an injection-molded part's tight tolerances. However, shrinking and warpage commonly occur as part complexity increases, meaning ...

Injection molding tolerances and their impact on part quality

Jun 06, 2022·Tolerances in injection molding have an impact on part sealing, which has a direct effect on part quality and performance. Incorrect seals can allow fluids or atmospheric elements to enter critical components. They can also allow fluids or air pressure to escape from components. It’s a risk. INJECTION MOLDING TOLERANCES

Why are plastic component tolerances important?

Sep 22, 2021·Part tolerances refer to the dimensions of a component. For example, the tolerances for a hole within a component might sit within a range of 0.5mm. This means the final dimension of the hole can deviate by + or -2.5mm less than the set dimension. Also known as a base point or nominal value, it won't significantly impact function or aesthetics.
