Understanding the Process:
In high pressure injection molding, molten plastic is injected under high pressure into a water cooled steel mold. The plastic is held under pressure while it cools and the molded part is ejected.
High Pressure Injection Molding is often the process of choice when structure, strength, volume and exceptional value are required.
Pro’s
- Fast cycle times / high volume
- Detailed part geometries
- Tight tolerances
- Part to part consistency
- Wide range of material options
- Cost effectiveness for applications requiring high volume
Con’s
- High equipment costs
- High mold costs
- Longer lead times
- Costly to change
