How Our Machines Are Made
How a Bottle Packaging Machine Is Born
Buyers ask first whether we machine our own parts or assemble bought-in ones. The answer is the four steps every LONGSN machine passes in our own workshop in Zhangjiagang, shown here as it looks on the floor.
-
Core Parts Machined In-House on the CNC Center
High-precision CNC machining center
Frames, cutter seats and change parts are machined on our own high-precision CNC center, so the tolerances that decide a machine's precision are set in our workshop.
-
Electrical Cabinets Fitted with European, American and Japanese Components
PLC, sensors and pneumatics from established brands
Every control cabinet is fitted with electrical components from Europe, America and Japan — brands your maintenance team already knows and can source locally.
-
Assembled and Commissioned by Our Own Engineers
68+ production, installation and commissioning engineers
Machines are assembled, wired and test-run in Zhangjiagang before packing. The same team travels to install the machine and train your operators.
-
Packed for Export and Shipped
Film and wooden case packing
The finished machine is inspected, packed in film and a wooden case, and shipped from the Yangtze River port next to Shanghai to more than 45 countries.
