Organizing Intra-company training

PROFEVER develops tailor-made training modules, focused on the concerns of each manufacturer or partner who is looking for glass-related knowledge, based on an accurate analysis of the company’s training needs. These tailor-made training sessions take place on industrial sites, after agreeing on a program, a duration moreover they are in keeping with the level of the trainees such as engineers, technicians, supervisors, operators.

During the training, a practical part regarding lines and equipment of the plant can be included (laboratory, composition workshop, furnace, feeder, annealing lehr, measuring stresses, on-site breakage analysis, manufacturing line audit, packaging line audit).

A few examples

The annealing training will be adapted to the company’s products (bottles, perfume bottles, flat glass, windshields, etc.), the equipment which is used (lehr hollow glass, lehr flat glass, glass bending, etc.). One visits the lines. The speaker discusses about settings with trainees, the latter offers solutions to their problems. Stress measurements are carried out with the company’s equipment (polariscope plan, Senarmont compensator, Babinet, Sharple, VRP, Gasp etc).

The origin breakage training will be adapted to the products and issues of the company: pressure bottle breakage, thermal shock, mechanical jars or bottles, perfume bottles checks, flat glass breakage, windshield. Tests may be carried out using the equipment of the plant (pressure resistance test, thermal shock).

The temperature measurement training is adapted to the equipment of the company: thermo-couples, pyrometers, platinum probe. Practical advice will be given on the installation and usage of these materials, to analyze the obtained results.

Glass packaging training could be given in bottling centers that shall revolve around specific issues that are encountered. A visit of the lines will be carried out with the interns, to identify the critical points.
