Making injection models is both a craftsmanship and a science. Abnormal amounts of specialized skill and tender loving care are required to keep little errors from costing organizations huge cash with ass-production of novel parts.
Counteracting such a situation is about exceptionally capable 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. Conversely, creative solutions and ingenuity abound in personnel with the right experience and the correct combination of hardware and software. Finding the right team of people with relevant expertise is the most important part of the process.
