Molded Fiber Finished tableware is cracked during the setting process

With the implementation of the plastic restrictions on various countries, more and more enterprises have transformed the production of plant straw fiber tableware. At the same time, some universities, institutions, equipment factories, etc. have also invested in innovative technology research and development, making the development of the industry enter a one The golden period of rapid development.

(1) Molded Fiber Finished Products Is Thin
The thickness of the general product in the production process of plant straw fiber tableware is about 0.7-0.8mm. Sometimes the requirements for use or customers often reduce the thickness of the product to 0.5-0.6mm. Net transfer is easy to crack the product due to the action of the network or the deformation of the network.

(2) The design of the mold itself
The mold gap is small. The smaller gaps mentioned here are mainly for setting thermal pressure molds. If the production party does not tell the thickness of the product factory when opening the mold, the mold factory often performs the calculation of the expansion coefficient and the gap of the gap according to the conventional thickness of the product. Reserved, however, in the actual production process, if the thickness of the product exceeds the design gap or exceeds the gap of the mold at the design temperature, it will cause the product to crack, and even some products will "blew up".

The molding mold is not matched with the molded mold. Whether it is depth, length, and width of the mold molding mold, it is often greater than the molded molds, especially for some products with deeper depth and smaller slope. Creation of wet embryo, if the secondary supercharged, the product and the metal network are more likely to be cracking by pressure.
