Purpose
- Optimize the quantity of rubber used in injection machines purge process
- Avoid contamination of final product due to vulcanization of rubber
Project Scope
- Optimize process parameters to avoid pre-injection vulcanization
- New parameter and process settings
- Validate the process settings based on experiments
Solution Approach
- Study the different parameters affecting the rubber vulcanization before injection
- Different experiments were designed (DOE) to prove the hypothesis established during the analyzing period
- Enhancing the operator awareness
- Different process improvement opportunities were identified and embedded into the company planned actions in Continuous Improvement
The Results
- 22% reduction in pre-injection vulcanization
- Approximate cost savings- ~€ 82,000 / year
- Significant reduction in the amount of material wasted during the purge leading to important material savings
Systems, Tools & Services Expertise
- DMAIC (Define, Measure, Analyse, Improve, Control)
- ANOVA
