Automatic loading machines for GRAND PATRON cartridges are installed at all production facilities of the Cartridge Manufactory: in Tula, Timashevsk and Zarinsk.
Technological operations of automatic loading of cartridges are carried out on the Vasini loading machibes. The process of equipment, loading and geometry of components are continuously monitored by electronic sensors. Automation allows eliminating the influence of the "human factor" and producing high-quality products with stable ballistic characteristics.
Cartridge parameters are controlled with the help of Swiss-Italian computerized measuring systems "Stas".
Before loading a particular cartridge into a batch, all its components are carefully selected. Several cartridges are pre-loaded by hand with various weights of powder according to the recommendations of the powder manufacturer and our own experience.
Cartridges are tested on a measuring complex and a specialist technologist, analyzing the results, selects cartridges that have optimal parameters. In case of unsatisfactory results, this procedure is repeated.
Then the loading machine is adjusted: powder, shot, wad dispensers, components control sensors, the height of the cartridge is selected. After a trial run of the line, the first cartridges are withdrawn and they are re-tested on the measuring complex.
If the results are positive, a decision is made to start the loading machine. If unsatisfactory results are obtained, the necessary adjustments are made again and the test procedure is repeated.
In the process of batch production, at the beginning of each shift, current control tests are carried out, and after the manufacture of 2500-3000 cartridges, a control weighing of the powder and shot sample and, periodically, checks the compliance of loaded cartridges with control samples.
When the batch is closed, acceptance tests are carried out at control and test stations (CTS).
