Plastic shaping be used in common for plastic products to manufacture.Basing on the actual plastic products of electric blanket, the designer uses the actual model to measure the product, creates a model for the actual product and making an analysis to the materials and structure of  the product. Designs the plastic mould,  including the design of plastic finished product, analysis and account of craft parameter, the design of work piece, mould structure and the processing project. The designer focuses on the design and account work of parting-surface and slide. Using  the designer uses Moldflow Plastics Insight 6.1 to make an analysis of the product，deciding the best location. And making a increase Basing on actuality to get the best effect . After deciding the number of cavity for mold ，using Moldflow Plastics Insight 6.1 to make an analysis for air pocket，weld lines，fillingtime，bulk temperatures of sandouting，temperature at flow front，pressure at V/P switchover point，screen out pressure，pressure at injected location and so on， to sure the rationality of  mould design. The last using Pro-Engineer4.0 and EMX4.1 module is applied to the whole design.
