About us

The history of IPROTec GmbH is based on the development, design and construction of machines for glass production. With the constant further development of the regional glass industry the company grew into an efficient producer of systems and machines in this field.
After the company moved from Grafenau to Zwiesel onto the company premises of Zwiesel Kristallglas AG and the thereby associated synergistic effects, we were able to further expand our technical competence in the mechanical and plant engineering sector for the glass industry.

Together with Zwiesel Kristallglas AG we have developed a great number of patents in the field of (drinking) glass production. As a result, we are able to produce complete manufacturing plants for you. The basis for this is our highly qualified personnel, who support you with professional knowledge and technical process know-how.

blowing machine

The product of continuous development in the production of Zwiesel crystal glass is a blow moulding machine that enables the highest quality and can produce up to 60 glasses per minute using the blow-and-blow process. As a result of its modular design, the construction is extremely flexible and in the case of necessary repairs, individual segments can be exchanged easily and quickly, thus downtime is greatly reduced.

laser filament cutting

An innovative laser process, adapted from the processing of tempered display glass to the processing of hollow glassware from iPROTec, has created a revolutionary process for separating the excess glass.

automatic glass inspection

Our testing systems provide automatic glass inspections for all relevant flaws. This innovative new product is based upon optical inspection systems that have been in successful operation in production at our partner company, Zwiesel Kristallglas AG, for the past 20 years.

Scope of inspection:
• Goblet inspection (shape)
• Goblet inspection (cosmetic flaws)
• Goblet base inspection
• Stem inspection (shape and bubbles)
