At the beginning of 2007, the company where the author worked successfully introduced a Roland 706 + LV used printing machine. In October 2006, shareholders will be held to discuss matters on Ma Luolan machine, unanimously approved the purchase scheme as soon as possible. Subsequent research on equipment research, information release, and capital regulation started simultaneously. On November 18, the first field trip to Shenzhen was conducted, and on December 17, the second field trip to Shenzhen was conducted to inspect the machine. In the meantime, in order to ensure the authenticity of the purchased machine, the purchase team was extremely cautious, collected information from various parties, and revised the technical parameter requirements with reference to the market conditions. The second mobile phone inspection report and machine inspection notes have dozens of pages. Shang admired. On January 11, 2007, the machine passed through customs and reached Shenzhen. On the 22nd, the machine was inspected again and loaded and shipped. Arrived in Shandong factory on the 25th. The employees of the workshop struggled for two days to put the equipment in place, and took two weeks to complete the installation and commissioning of the equipment. Official production will begin on March 9.
In just three months, the bidding, inspection, purchase, installation, and formal production of Roland 700 were completed. Such efficiency is not easy to achieve even when buying a new machine. What is even more commendable is that after the introduction of the second mobile phone, the production workshop quickly deployed technical personnel to follow the external teacher to learn the operation, learning while doing, learning while doing. One month later, the operation skills of the two captains have greatly improved improve. The large-format, 15th edition version of the medical packaging cartons produced were basically successfully sampled in one pass. It can be said that from the purchase of a machine to the expansion of the pharmaceutical packaging market, this speed is also rare in the industry. Therefore, the author simply sorted out the precautions for the inspection of second-hand printing equipment and encouraged them with their counterparts.
