Production rate of injection molding machine depends upon cycle time (total time that machine takes to produce a product in one cycle) and the number of cavities. For calculating cycle time, you must consider time for each phase that machine takes in one cycle. That phases are:
- Mold closing / clamp
- Filling
- Pack and hold
- Cooling and Recovery (40-60% )
- Mold Open
- Ejection
Add time taken by each phase. For example, this time is 15 seconds and the number of cavities are 2. So the production rate is 2 finished product per 15 seconds. You can increase your production by decreasing the cycle time. You can decrease cycle time by following some points:
- Keep wall thickness to minimum required for your product
- Ensure your machine is fine-tuned
- Ensure proper cooling system, injection pressure and injection speed is applied.
