# 6.1 Whether to simulate carton expansion and manual interval

The size of [corner casting ](/4-ui-and-terminologies/4.4-containers/4.4.2-attributes-of-the-containers/4.4.2.1-corner.md)is 10\*10\*10cm. How to simulate carton expansion and manual interval reasonably？

Ⅰ The packaging boxes are all carton packaging, or most of them are carton packaging and only few of them are wooden boxes and iron boxes, etc. They are directly packed by manual work.

1.If the size of the goods is actually measured, the goods is loaded directly after production, and the container size is the standard inner inch (i.e. 20GP: 589\*235\*239CM, 40GP: 1200\*235\*239CM, 40HQ: 1200\*235\*269CM), at such condition, two methods can be set to simulate the situation of manual interval.

1\)You can set the reserve size of container in \[container] page. When set the reserved size at the first time, the recommended values are as follows,

20GP reserved 5-8CM in length, 3-5CM in width, 3-5CM in height

40GP/40HQ reserved 10-15CM in length, 3-5CM in width, 3-5CM in height

2\)Reasonably set the \[spatial separation] in the \[Loading Rules] page.

2.If the goods are packed in cartons, the size of carton is theoretical value, and the goods will be stored in the warehouse for more than one or two weeks after production, in such condition the expansion of cartons due to the backlog in the warehouse should be considered. According to the test of Japanese experts, the extent of carton deformation caused by the backlog of goods in the warehouse is 1%-1.8% of the original size.

1. If the size of the cargo has been enlarged by 1-2CM, there is no need to set the reserved size of container or cargo spatial separation.
2. If the container size has been reasonably deducted, there is no need to set the reserved size of container or cargo spatial separation.

Ⅱ If the packing boxes are all wooden boxes or pallets or iron boxes, which do not involve carton loading, or only a very small number of cartons. And a forklift is used when loading.

You can set the reserve size of container in \[container] page. When set the reserved size at the first time, the recommended values are as follows,

1.20GP reserved 5-8CM in length, 3-5CM in width, 10CM in height

2.40GP/40HQ reserved 10-15CM in length, 3-5CM in width, 10CM in height

3.The \[reserved height] of container should be deducted by 10CM, which means the 10CM of corner castings is also deducted, therefore the size of corner castings should be set to "0".
