Molded Glass Bottle Manufacturing
Raw Material Preparation
Raw materials (containing oxides of silicon, boron, sodium, potassium and aluminum) are delivered in powder form and stored in silos. All our suppliers are audited and the consistently high quality of our raw materials is confirmed by certificates of analysis.
The ingredients are mixed fully automatically using a precision metering system and automatically controlled conveying and mixing equipment. The system is fully automated and computer controlled, ensuring consistency in the final glass composition. Waste glass is added to the powdered raw materials in a certain proportion. The raw materials are then transported to the melting tank via a conveyor system.
Glass Melting
The melting process is the core stage of glass production. The ingredients are melted at a temperature of approximately 1600°C. The aggregates are heated electrically and the melting tank operates 24 hours a day.
Production and Forming
The machine consists of a series of independent container manufacturing units, each of which operates completely independently according to the press-blow process.
Bottle Forming Machine: Press-Blow Process
Press-blow manufacturing involves forming the liquid glass into the appropriate shape using a plunger and a mold. At this point, the threads are formed by pressing. The product is then placed into a second mold using a fixture and blown into the final shape.
Quality First, No Compromise
This quality control system is the basis of every process for our products, from the first customer inquiry to order processing, delivery and customer feedback. We value the success of our products because it proves the trust our customers have in our quality system, logistics and service. Furthermore, we continuously improve our performance by continually evaluating the current situation, setting new ambitious goals and working towards achieving them through process-oriented thinking, planning and action.
