Four Steps Ensuring Safety And Efficiency Of Machine Preparation And Shipment

Keeping in mind a Chinese old saying that “Jade must be cut and chiseled to make it a useful ware” (a person must be disciplined and educated to be a useful citizen), ThoYu has always been upholding the spirit of craftsman at every stage, especially for the stages of machine preparation and shipment.

Quality test before delivery
Upon completion of the manufacturing of equipment, the quality inspector strictly checks quality of every machine with the checklist.


Check items when packing
Before packaging and shipment, the order tracking clerk checks the packaged items again with the packing list to avoid loss of items.


Packaging and transport
Professional packaging and modular solution of transportation guarantee the safe and smooth delivery.
