Volume weight of plastic parts :
The weight of the plastic parts is calculated in order to select the injection machine and determine the number of mold cavities.
Calculate the volume of plastic parts: Use PRO/E software to draw a three-dimensional solid map, the software can automatically calculate the drawing
The volume of molded parts. V = 1460mm

Calculate the quality of plastic parts:
The formula is W = Vρ (2-1).
Acrylonitrile-butadiene-styrene copolymer ABS was obtained according to Table 12-3 of "Practical Mold Technical Manual" P235
The density is ρ = 1.13-1.14 kg/dm
3, the value is 1.135 kg/dm 3
Therefore, the weight of the plastic parts is:
W = Vρ = 1460× 1.135 ×10
- 3
= 1.657 g
According to the pressure required for injection and the weight of the plastic parts and other circumstances, the injection machine can be initially selected
