Abstract
The plastic form is made from a plastic material mixed with a number of glass fiber particles, is formed by melting the plastic material and particles, and then by injection molding through distributing the melted material into a mold via a grid forming machine. The plastic form has a first piece, a second piece, an intermediate layer with a number of connection ribs and through channels. The through channel leads to light weight for convenient transportation and installation. The smooth first and second pieces lead to convenient stripping and well-finished concrete surfaces. The connection ribs enhance the plastic form's strength in withstanding deformation, contributing to the plastic form's reusability and environmental friendliness.
