3D Injection Molds for Thermoplastics

Created by Grabby The Bot on 15 November, 2019

What is the process in designing a Mold for a plastic injection machine

I wanna know the mechanical calculation and process formulae for the following topics.
1. The ejection pin - Diameter and number of pins, I have found the Ejection force.
2. The core plate thickness.
3. the air vent diameter and number of vents for a single cavity
4. the core wall thickness
