1. Evaluation of molded products
(1) the shape is correct, the size is accurate, and the precision
meets the requirements; secondly, the appearance is beautiful, the color
and lustre is uniform, there is no defect, there is no obvious closing
line, and the physical and mechanical performance index is qualified.
Two. Evaluation of life span
(1) the selection of mould material is correct and high quality,
and the heat treatment meets the design requirements; secondly, the
surface of easily worn parts is smooth, the hardness is high, and it
meets the requirements; 3. It can reach or exceed the budget life, and
can meet the requirements of recycling.
Three. Evaluation of molding process
(1) the control requirements for technological conditions are not
high, the selection of technological parameters is limited; second, the
adaptability to materials is strong; (3) easy to mold release; (4) the
molding cycle is short.
Four. Requirements for the mold of the slope protection
(1) the structure is reasonable and the appearance is neat. 2. The
volume of the gating system is small. 3. The surface roughness and
surface treatment of the mold cavity and core are in line with the
requirements of the die users.
