When manufacturing in China it is imperative to visit factories often and control all aspects of production. This is often a difficult task when located halfway round the world.

The first process in cardboard cutting is to cut the large piece of cardboard down in to a smaller piece of cardboard. This smaller piece of cardboard is then cut down into a smaller piece of cardboard. This process is repeated until the desired size of cardboard is reached. After this the cardboard begins it’s journey in to die cutting.
Die cutting is where the design is cut out using the pressure. As seen in this video the worker moves one piece in to the die while pulling the die cut piece out at the same time, meanwhile the machine keeps moving. This process can be slowed down for different materials, for example when die cutting PU the machine is slowed due to the PU having less rigidity and therefore being more difficult to place accurately.
The printing process is started by creating desired colour of paper and printing the desired design onto the coloured paper. This process needs to ensure that the paper is the correct colour on both sides. The paper is fed through print rollers to apply the logo smoothly.
It is then critical to allow the print to dry for the correct amount of time due to the stress put on the print during the following steps.
Lamination is when the paper is passed through rollers and attached to the lamination film that is also being fed through. This results in the paper not only having a glossy finish but also having increased strength.
Following lamination the laminated paper is now passed through another machine which coats the inside in glue. Following this, the die cut cardboard is applied to the paper. As seen below, the final process is to smooth the sides over and create the finished foldable piece ready for final assembly
The required pieces are then glued inside and shaped for assembly into the finished box.
The final production step is to allow the box to dry thoroughly prior to shipment to the client.
Once fully dry the boxes are ready to be QC’d and packaged into cartons before being shipped out.
