Injection-moulded-plastic-part design must ensure that the part can be manufactured to the desired quality level by the injection moulding process. Simulation software has been widely used in industry to assess mouldability and measures of quality. However, it cannot be used to improve a design directly. Design modifications must be performed by the designer after evaluation of the simulation results. Based on the authors' previous work on injection moulding CAD-CAE integration, this paper explores the strategies and methods for automatic-partshape-modification to attain a desired part quality. An enhanced CAD-CAE integration model is developed. This model is used to specify the shape-modification variables, as well as the mouldability and other quality measuring criteria. The shape modification variables include positional and sizing parameters of each individual feature, as well as those associated with the part, such as part thickness. With this information, an iterative process of part-shape modification and execution of simulation subroutines is carried out automatically, and the results are verified and evaluated. Optimal shape, according to the specified criteria can thus be derived from the evaluation results. A software prototype has been developed. A design case study is presented to illustrate and demonstrate the usefulness of the proposed strategies and methods.

“…This is achieved by the original integrated injection moulding design system [16]. The procedure can be roughly described as follows: the designers first create a gate location marker, that is, a circle sketch on the surface or edge of the part geometry (see Fig.…”

“…Besides, in order to provide users flexibility in specifying their own quality measuring criteria, a model allowing users to specify both design and analysis-related information is also necessary. The authors have developed a CAD-CAE integrated injection moulding design system [16]. Based on this system, a specification model has been proposed which is used to automatically interpret CAE results [13].…”

Moulding conditions design refers to parameter settings of moulding conditions such as melt temperature, mould temperature and injection time. They are important factors in plastic injection moulding design. The determination of these parameters is a highly skilled job and has largely been dependent on injection moulding engineers' experience and intuitiveness. In this paper, the authors present a flexible computer-aided system to assist the designers by using simulation-based technology. One of the most prominent characteristics of the system is that it allows the designers to specify their intended quality measuring criteria such as minimum cavity pressure and shear stress, a uniform distribution of cooling time, end-of-fill temperature and volumetric shrinkage. The system uses weighted criteria as an objective function to determine optimal moulding conditions when multiple criteria are specified. Moldflow simulation results are used to compare different designs. A two-step exhaustive search strategy (from coarse to refined) is used to search for a near-optimal design.

“…Organizations continuously spend up to 50 percent of their information technology budgets on application integration [6]. In the manufacturing industry, there are much research efforts on the development and standardization of systems that integrate computer-aided design (CAD), computer-aided engineering (CAE), and computer-aided manufacturing (CAM) applications for product design, development, and manufacturing [7][8][9][10]. Tools that can potentially facilitate collaborations among supply chain members have also been proposed [11].…”

Supply chain management integrates key business processes and facilities, involving end users and suppliers that provide products, services, and information. Supply chain integration can potentially add value to the stakeholders along product development and manufacturing life cycle as well as the customers in terms of cost, time, service level, quality, and risk. In the manufacturing industry, there are many attempts to develop methodologies, standards, and technologies to integrate various applications for product design and manufacturing. However, studies on integrating and aligning product design and manufacturing with other operations in supply chains are relatively lacking. In an integrated supply chain, information, applications, and services are shared and become available among supply chain members within and across organizational boundaries. Existing technologies and tools such as Electronic Data Interchange (EDI) infrastructures and Enterprise Resource Planning (ERP) systems do not provide a flexible and reusable solution to information sharing and application integration. This paper presents a prototype service oriented web-based system, SC Collaborator (Supply Chain Collaborator), which leverages web services, web portal, and open source technologies to provide a flexible, customizable, and economical tool for supply chain integration. The prototype system implements a service oriented portal-based framework and allows service orchestration according to processes. This paper presents the service oriented portal-based framework, the system architecture of SC Collaborator, and the schematic representation and implementation of process models with the system. The paper also illustrates the use of the SC Collaborator system to facilitate cross-functional, crossdepartmental, and cross-organizational collaborations using a bus manufacturing scenario.
