What is injection accuracy?

Factors affecting injection molding accuracy

Mold design: The design is good or bad, whether the product can be smoothly formed production and precision control is crucial, is the beginning of all work.
Die machining accuracy: The accuracy of the die is essential to ensure the accuracy of the part. High-precision molds can produce parts with accurate size and shape and small tolerances.
Machine accuracy: The accuracy of the injection molding machine is crucial to controlling process parameters such as injection pressure, injection speed and pressure holding time. High-precision machines can produce consistent parts with a narrower tolerance range.
Material characteristics: The characteristics of plastic materials, such as shrinkage and fluidity, affect injection molding accuracy. Using materials with low shrinkage and good fluidity can help reduce part deformation and dimensional changes, but more often than not, materials have been prioritized.
Process parameters: Injection process parameters, such as injection temperature, mold temperature and injection pressure, affect the size and shape of the part. Optimizing process parameters is very important to obtain high injection precision.

Measures to improve injection precision

Good mold design and inspection.
Use high precision molds and machines.
Optimize injection molding process parameters.
Implement quality control measures such as first piece inspection and statistical process control.
