how to calculate the general need clamping force according to the perpendicular area of the product
Clamping force=clamping force constant × projection area of the product
i.e. p = Wps
In which, P—- clamping force (t)
S—- perpendicular projection area on the platen (cm2)
Kp—clamping force constant (t/cm2)
Kp is listed in the following table 1
Table 1 clamping force constant Kp (for precise products)
Plastic Description | PS | PE | PP | ABS | NYLON | POM | Fiberglass | Other Engineering Plastic |
Kp (t/cm2) | 0.32 | 0.32 | 0.32 | 0.30 | 0.64~0.8 | 0.64~0.8 | 0.64~0.8 | 0.64~0.8 |
