For over 25 years, the Jolly Motor group has invested its own profits in the research of new production and control technologies with particular attention to progress, interest in innovation and marked selectivity by focusing on market practices and tendencies. For instance two specific production units have been developed and patented by Jolly Motor in specifically equipped laboratories where regular tests and monitoring take place through strict controls such as resistance test (95% humidity), temperature (from -25° to +80° C) and robustness tests (operating for more than 10.000 cycles).
