Melt Temperature 320 deg.C 7. Melt Temperature Minimum 260.0 deg.C 8. Melt Temperature Maximum 320.0 deg.C 9. Mold Temperature Minimum 90.0 deg.C 10.Mold Temperature Maximum 105.0 deg.C 11.Maximum Shear Rate 40000.0 1/s 12.Maximum Shear Stress 0. 5 MPa (Moldflow database have no the appointed material, so replace with the similar material, and the analysis results are similar) Product Introduction The product is the automotive instrument cluster, its length is 334mm, and width is 147mm, height is 57mm. The product structure is complex, and has asymmetry thickness. The nominal thickness of the product is 1.50mm, and the thickness of Disk1Disk2 vary from 1.1mm to 1.2mm, the Area3 is very thin and the minimum thickness is only 0.7mm, so these areas are difficult to fill. Some areas are thicker, which may induce to sink. 1 2 3 Mesh Thickness Basic Molding Conditions Introduction Injection Molding Machine: Machine maximum clamp force: 300 ton Maximum pressure: 180.0 MPa Filling Conditions: Mold temperature: 90.0 deg.C Melt temperature: 300.0 deg.C Injection time: 1.5 sec Part volume to be filled: 154.0330 cm^3 Total projected area: 337.9040 cm^2 Cooling Conditions: Cooling Time: 20 s Note: The analysis take no account of cooling lines. You can choose the best case base on the flow analysis results, and design cooling lines considering mold structure. Pack Pressure Step Duration [MPa] [sec] 80.0
