Ways to Ensure Quality Manufacturing
To ensure the total quality of each Dolz product, the commitment of the different departments of the company is necessary. All developed processes must be integrated. Only in this way will we obtain a continuous improvement of the development, design, and manufacture of the product.
Incoming reception, the verification of the first piece or the different follow-up audits, finished product and shipment are some of the different inspection methods applied in manufacturing processes with which we ensure full quality control in 100% of our product ranges. It helps to identify any issues with shortages or damaged goods.
To these techniques we add different tests and procedures. One of them, used in DOLZ water pumps, is the tightness test using a calibrated leak instrument, which automatically detects leaks through pressurized air. A simple and essential process that, with many other factors, become DOLZ water pumps the highest quality on the aftermarket.
This tightness test introduces air at a controlled pressure to the surfaces of the water pump that will be in contact with the coolant for a specified time. After a stabilization period, the air pressure drop is checked to be within the defined tolerances.
This enables the possibility to verify the results and perform other quality controls and protect the final customer from obtaining a defective product.
