The client, a high-volume Packaged Drinking Water plant, was operating an aging fleet of conventional PET blow molding machines to supply their high-speed filling lines.
Due to shifting consumer demands, the plant required frequent changes between different bottle shapes, sizes, and preform weights (e.g., switching from 500ml water bottles to 2L carbonated soft drink formats). Because the existing blowing setup relied on legacy mechanical indexing and manual mold allocation, the system spent an excessive amount of daily operational time in an unproductive 'downtime' state during changeovers.
This operational mismatch led to massive production bottlenecks, low Overall Equipment Effectiveness, and significant material scrap during startup stabilization cycles. The resulting latency in production transitions directly threatened factory uptime, disrupted downstream filling schedules, and caused substantial lost productivity during format changeovers.
Our engineering team conducted a comprehensive production cycle and line layout study to map the factory's precise bottle output and mechanical layout requirements.
We recommended deploying a state-of-the-art Rotary PET blow molding machine equipped with advanced Sidel made molds which reduced the changeover time considerably along with lowest bottle blowing cost and rejection ratio.
The new Sidel blowing machine was integrated directly with the downstream line controls to dynamically match the line's filling speeds. The equipment featured electrical stretching systems for precise material distribution, an optimized preform heating oven to minimize heating energy.
Measurable ROI
Customer Experience
“Production flexibility is non-negotiable for our facility. Before this upgrade, changing bottle formats felt like a massive bottleneck that stalled our entire packaging hall. This new Sidel blowing system gives our operations team absolute peace of mind. It handles recipe transitions seamlessly, scaling perfectly with our high-speed filling lines while drastically cutting down on preform waste and setup downtime.”— Plant Operations Manager
