Making injection molded prototypes is both an art and a science. High levels of technical expertise and attention to detail are required to prevent small mistakes from costing companies big money when it comes to mass-production of novel parts.
Preventing such a circumstance is all about highly competent design. This article discusses some of the molding defects that can occur in a part during injection molding, and ways to fix and avoid them. Design shortcomings we will discuss include:
Flow Lines
Sink Marks
Vacuum Voids
Surface Delamination
Weld Lines
Short Shots
Warping
Burn Marks
Jetting
Flash
Most mistakes are caused by nescient personnel without the necessary experience or the right tools at their disposal.
