Sample Solutions
Bucks
We produce a range of components and parts for glass manufacturing machines and glass blowing machines, such as bucks, cooling boards, stackers, transverse belts, grippers and levers.
Gripper fingers
Gripper fingers have component-specific contours at their ends that enable them to pick up, grip, transport or guide components. They are used primarily in electronics manufacturing.
High-voltage insulation
What sets these types of insulators apart is the combination of different requirements that simultaneously apply to their implementation.
Complex 3D components for thermal insulation
The manner in which these insulation materials are implemented can be as varied as the requirements placed on them: from a simple intermediate layer all the way to complex 3D components with various material combinations that are produced on a 5-axis…
Blank holders
Blank holders serve to hold components securely in position in the application. They are typically held against a surface/contour.
Screw head insulation
During the process of pinning and screwing components, electrical insulation must frequently be guaranteed. Ceramic cylindrical pins ensure a positive connection while a steel screw provides for the positional connection - the interlocking connection…
Goods carriers
Goods carriers are used to hold other products, such as circuit boards. In many cases, they must be electrically insulating, wear-resistant and designed to cope with thermal shock to enable smooth handling.
Non-material-specific insulation solutions
In many industrial applications, it makes sense to use multi-layered materials or material combinations.
Workpiece holder/carrier
The exact positioning of components is particularly important for series production. Here, multiple components are frequently welded, bonded, riveted, soldered, etc. at high cycle rates to form assemblies.
