PLAST-TOOL CLEANING SERVICES
PLAST-TOOL CLEANING SERVICES S.L. – Part of WTS – is located in Esparreguera (Barcelona) and it is especially dedicated to clear all the elements such as extrusion dies, injection nozzles, die plates, filter elements, “bypass” valves, gear pumps, laser filter elements, shut-of nozzles, etc…, that contain polymers vestiges using a clearing oven under controlled atmosphere , that makes the operation, Safe and Fast.
Our motto is a fast and efficient service !!!
The system involves the complete melting and degrading of the polymers under an inert atmosphere “without oxygen”, and there is no risk of combustion, which makes the oven absolutely safe.
The PETRELLI patented infrared technology insures an immediate heating process (very short pre-heating time), which is highly efficient and very economical (approx. 130 minutes per cycle).
Thanks to the PLC system, who controls the cleaning process, degradation and damaging of the parts is avoided during the process, due to the elevated temperature (deformation, cracking and charring of the surfaces).
The maximum temperature is limited to 450ºC. This temperature limitation can be unlocked with a password / under formal request.
After the parts are placed into the oven, the door locks in order to prevent the operator to open it during the whole, until the oven cools down, to guarantee a correct cleaning process.
The operator selects on the PLC-PC the required cleaning process according to the polymers types.
The cleaning process is fully automatic and therefore saves time and allows flexibility.
Once the cleaning process is complete, the door unlocks, the operator retrieves the pieces leaving them cool down to room temperature and the machine is ready for a new work cycle.
