Steering Wheel Material Properties The material of plastic parts is ABS,an engineering plastic with good comprehensive properties.It has good processing and molding properties,excellent dimensional stability,high impact strength and good appearance characteristics.Properly increasing the mold temperature can improve the smoothness of the plastic parts.The material density is 1.02-1.05g/cm3(injection grade density is 1.05g/cm3),the theoretically calculated shrinkage rate is 0.6%,and the flash value is 0.04mm. Steering Wheel Injection Mold Design Steps Parting Design When establishing the parting surface,the steering wheel injection mold design first establishes the parting surface for one mold one cavity,divides the volume block and casts the mold for one mold and one cavity,and then established the parting surface of one mold and two parts.In the parting process,the left and right corners of the plastic part are the most complicated.These two parts are the intersection of the parting surfaces,and there is a certain gap between the parting surfaces.Therefore,the general parting method is used.The volume block can not be divided,and the total parting surface can not be obtained.The steering wheel injection mold is designed by selecting the modeling line on the product to project it onto the workpiece,and then strectching the projection line through the upper surface of the product to become a polygonal parting surface,and finally merging all the side parting surfaces.This mold is a one-piece two-piece layout,so the boundary mixing method is used to establish the parting surface between the two parts,and then all the parting surfaces are merged to establish the total parting surface. Steering Wheel Injection Mold Gate Design Since the side gate is generally opened on the parting surface and the material is fed from the outer side of the plastic part,the gate cross-sectional shape is simple,the processing is convenient,the traces left on the p
