In the chapter of equipment type selection, combining with the design of production technology and the best working point, for each process to select appropriate equipment, and gives the related parameters of each device, such as type, size and power. This parameter can be energy balance and economic calculation and arrangement of the plant to provide powerful basis. 

In material balance chapter, based on the conservation of mass was carried out on the material balance calculation. First, make sure material balance calculation benchmark, including production days, production time, and each link of attrition rate, etc. Second, after the process flow diagram is given to calculate the consumption of raw materials and production of products, consumption of each stage in the process of production and composition and so on. At last, the integrated table of raw material consumption is given to economic accounting. 

Total process flow, the reference related literature, to determine the total production process and raw material pretreatment process diagram, and to specify them. Refer to plastic machinery design standards, refining process required for each step of technical parameters and models. 

Working time was determined by the material balance, and the corresponding number of the main equipment. At the same time, lists the various production and the amount of loss and waste in the process, provides a reference for the quantity of materials required for the design. 

In the energy balance in chapter. First shows the flow chart of energy balance, and the energy transfer process is necessary to briefly. Second, respectively for the injection molding system's nose and mouth part of the energy calculation, to calculate the amount of cooling water and chilled water. In the second section of this chapter, according to the production process of order, in the process of production equipment used by power calculation, and the total power loss is given. At the end of this chapter gives a comprehensive energy loss table. The table can provide the basis for economic accounting. 

In the content of the energy conversion, through extrusion molding machine and mold parts energy balance calculation, cooling water and chilled water dosage, and further to determine the specific usage. It is concluded that the design of the power consumption at the same time. 

In the workshop process design in the chapter, and the number of jobs for workshop personnel arrangements were briefly reviewed. At the same time, also considered the workshop ehs issues, including heating, ventilation and "three wastes" treatment and so on. 

Table in raw material consumption, energy consumption and equipment integrated table table was based on the premise of considering other factors, the cost of this design has carried on the estimate, the estimate of the results can be used as a judgment on the rationality of the design conditions. 

The content of the final plant layout design, simple workshop layout requirements and principles are introduced. Combined with the equipment selection and production process of workshop layout, specific to the design of the workshop layout made a brief description. The result appears in the form of workshop layout plan.
