Preventing microcracks

As two surfaces in contact slide off one another, there is a possibility that the contacts created will not separate again at their original interface. The surface disruption that occurs describes the formation of microcracks either on or just below the surface due to cyclical loading and unloading (e.g. ball bearings). Tribo-oxidation occurs if protective layers can be removed in a corrosive environment due to wear. In these cases, the surface is extremely susceptible to corrosion or its progress. 

High thermal conductance or materials that are not compatible with glass can cause microcracks to occur when hot glass is conveyed. These in turn result in rejects further down the production line and an inefficient process.

Sample Solutions


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.

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.

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.
