Fully automatic coffee machines manufactured by Colet need to pass 5 quality inspection processes before delivering to customers.
Incoming quality control
With precise instruments and specially designed inspection tooling, all incoming materials and components for bean to cup coffee machines will be inspected, avoid the quality risks that happen during assembling and use of coffee machines.
Automatic assemble-testing-feedback production line for coffee machine assemblies
The automatic assemble-testing-feedback production tools will assemble the main coffee machine parts, and test the quality of assembled parts automatically. If the testing feedbacks not reach expected technical date, the production tools will warn with sound automatically. This not only improved our production efficiency, saved human cost, but also guaranteed the quality and conformance of espresso machines manufactured by Colet.
Semi-finished product inspection
The assembled parts will be further assembled into semi-finished products in another production line, experienced workers will 100% test the semi-finished products with coffee bean and milk, check if ground coffee powder is fine and uniform, if the coffee machine can extract perfect espresso and make nice milk foam, if coffee volume and temperature is accurately, if water leakage happens on connections, if any parts have abnormal noise during operations and so on.
Finished product inspection
After the inspection of semi-finished coffee machine, third production line will assemble to final finished coffee machine. Before package, experience workers will 100% test the machine with hot water and milk again, check if all functions work correctly, if any parts have abnormal noise during working and so on. If everything fine, the coffee machine will be cleaned and packaged.
The quality inspection is not finished, Colet quality engineer will pick 5% of packaged coffee machines from warehouse, open the package, operate the functions, in order to final guarantee no parts missing and all functions are perfect working. Only got approved by pre-shipment inspection, Colet will release the order and deliver coffee machines to our customers.
