(Pure Liquid Eliminating Air Shock Equipment)

Our Customer, Naake Motorsports needs a machine that is able to remove air from a pre-assembled QA1 shock and then fill it with light weight shock oil. These are performance shocks typically used on race cars. The machine would be in a race shop environment and should also reduce the current cycle time to 5 minutes.
Our main goal in this project is to deliver a machine that is easy to operate and fits into the race shop environment while meeting all Naake’s requirements at the most affordable cost.
The machine is designed so that all of the air is removed from the shock absorber. This is done by creating a vacuum on the shock body and the shock fluid before it is put into the shock. With the absence of air in the shock absorber, the response to internal changes will improve considerably. This will also reduce hysteresis found in the shock through the same motion. The fluid flow of the machine is controlled using a Programmable Logic Controller (PLC) that responds to fluid level and pressure sensors as well as timers.
