This project is aimed at to choose some component molds from the existing steel molds,which are relatively simple, neat, easy to design and processing,

The objective of the project is to provide a type of lightweight, composite precast beam mold composed of the side mold of plastic material, the end mold of metal material and the relevant fixed parts.

The existing one-time foaming agent which used to prevent leakage has many shortcomings,We aime to provide a concrete precast beam anti-leakage plug to ensure that the gap opened on the mold of precast concrete members during construction will not le

This project aims to solve the defects of the traditional square bell-mouth structure concrete hopper, such as difficult discharging operation, not easy to control discharging speed, poor bottom closure,
