dc.description.abstract | One of important equipment in reforestation or tree planting is a pot for mulching
tree saplings. Originally pots were made of clay but they were too strong. When the
trees grow up, the pots must be smashed in order to let the roots and the stems grow
up. Plastic pots are a popular alternative to be potted tree saplings due to their longer
usability, flexibility, keeping and easy cleaning. In addition, they are light and easy to
move or transport. Typical pots usually have holes at the bottom which make poor
ventilation that caused the slow tree saplings growth. Pots with holes in the side let the
air comfortably flow and the roots do not go to the bottom of the pot. When the pots are
moved, the tree sapling roots are not ragged, this help reducing the mortality rate of
tree saplings. To Construct and find out the efficiency of plastic pot injection molded with
7.7 cm. in size, 8 cm. high, 0.10 cm. thick, and the weight of 20 grams in the specification
form, the work-piece can be injected. For Construction and finding out the efficiency of
holes for putting the plastic pot injection molded with 41 cm. wide 51 cm.long,0.20 cm. thick
and the weight of 330 grams in the specification form, every work piece can be injected.
There are 18holes for putting the plastic pot and all 18 holes are in the same size.
