when is it truly practical to design a cold sprue into a part or feed system? 

What are the key factors necessary for a reliable plastics injection molding report?

Is clamp force the only determining factor when determining the type of injection molding machine you need?

Valve Gates are invaluable as they relate to their primary design purpose and have many important functions.  They can: ✔ Eliminate waste that cold runners create ✔ Eliminate vestige ✔ Be sequenced ✔ Eliminate weld lines ✔ Control filling patterns However, users should be aware that there are a few potential issues that could come […]

Based on part geometry, gate location(s) will determine how the polymer fills the cavity.  If the cavity doesn’t fill in a balanced/uniform fashion, the internal stresses will be anisotropic- meaning non-uniform properties.  So it is important to place a gate in a location such that the polymer flowfront fills the cavity at a uniform rate […]
