18 cm plastic square watermelon mold is the best option .
A year ago ,the small square watermelon mold seems to be really welcomed by the market of China , because Chinese just love the small watermelon ,which is just fit 2-3 person , a small family in the China city . but as the demands from other country is keep raising , the big size of square watermelon mold is crazy needed , since most of the developed country such as the United States and European country , they love much bigger watermelon ,and the farmer grow like 20- 25 pounds as the usual watermelon size .
The bigger size of watermelon actually requires much stronger square plastic mold to hold the watermelon pressure and shaping them into cubic ,it not only need to increase the thickness of molds wall , but also need to add more Stiffeners ,to prevent it breaking by the pressure .which means the weight of molds has increased near double than the small size of square watermelon mold .
The new design square watermelon box is made up of 4 parts which is exactly the same , this design may seems more complex , but if you look at it more deeply , you will find the advantage ,if you have try with the other normal design of molds which made up with 2 parts , up and down ,you may have figured that it was really hard to more the mold off ,when the square watermelon is shaped and ripen , the pressure is just so big ,and hold the mold wall so tight . which make it is very time-consuming job to get the mold removed from the melon .
But now there is no such problem would happen again , because of the new design made it is very easy to get the mold removed , you just need to lose the screws on each size ,and there will be enough space to let the watermelon slip out .
The new design is based on the problem we found from the growing with our previous small square watermelon mold or box , now we have improved to make the experience much greater ,and the farmer will find more interesting to do this funny thing, and meanwhile to make the process of making money more enjoyable.
But convenience sometime always means more expensive , the bigger size square watermelon container is designed to shape bigger size watermelon ,and it used more material and more complex manufacturing art ,which all make the molds are double cost . but the molds can be used from many times , so if you have long business version , then it will not stop you from trying them .
