Extruding and Discharging Part Outlet diameter:Φ2.095±0.005 mm Outlet length: 8.000±0.025 mm Cylinder diameter: Φ9.550±0.025 mm Cylinder inner length: 152±0.1 mm Piston rod head diameter：Φ9.475±0.015 mm Piston rod head length: 6.350±0.100 mm B. Test Load Test load is realized through different combinations of a set of weights and a piston rod. There are eight levels these combinations can provide as nominal load that is necessary for testing: Level 1: 0.325 kg = (piston rod +weight tray +insulation cover +1# weight) =3.187 N Level 2: 1.200 kg= (0.325 kg +2# 0.875 kg weight) =11.77 N Level 3: 2.160 kg= (0.325 kg +3# 1.835 kg weight) =21.18 N Level 4: 3.800 kg= (0.325 kg +4# 3.475 kg weight) =37.26 N Level 5: 5.000 kg= (0.325 kg +5# 4.675 kg weight) =49.03 N Level 6: 10.000 kg= (0.325 kg +5# 4.675 kg weight +6# 5.000 kg weight) =98.07 N Level 7: 12.500 kg= (0.325 kg +5# 4.675 kg weight + 6# 5.000 kg weight+7# 2.500 kg weight) =122.58 N Level 8: 21.600 kg= (0.325 kg +2# 0.875 kg weight +3# 1.835 kg weight +4# 3.475 kg weight +5# 4.675 kg weight +6# 5.000 kg weight +7# 2.500 kg weight +8# 2.915 kg weight)=211.82 N C.
