This study aims to develop a method of controlling costs and time in relation to mold development, and also to imp
3、rove product design. This investigation comprises two parts: functional-ity coding, and establishing a standard operation procedure, specifically designed for beverage-container injection mold design and manufacturing. First, the injection mold is divided into several modules, each with a specific f
4、unction. Each module is further divided into several structural units possessing sub-function or sub-sub-function. Next, dimen-sions and specifications of each unit are standardized and a compatible interface is constructed linking relevant units. This work employs a cup-shaped beverage container to
5、 experimentally assess the performance of the modular design approach. The experimental results indicate that the modular design approach to manufacturing injection molds shortens development time by 36% and reduces costs by 19 23% compared with the conventional ap-proach. Meanwhile, the information
6、 on modularity helps designers in diverse products design. Additionally, the functionality code helps effectively manage and maintain products and molds.Keywords :Beverage container、 Injection mold、 Modular design、Product family1.IntroductionRecently, growing market competition and increasingly dive
7、rse customer demand has forced competitors to increase the speed at which they deliver new products to the market. However, developing a mold for mass produc-tion requires considering numerous factors, including product geometry, dimensions, and accuracy, leading to long product development time. In
8、troducing modular design concepts into product design appears a key mean of facilitating product development, since it increases design flexibility and shortens delivery time 14. Mean-while, a high level of product modularity enhances product innovativeness, flexibility, and customer services 5.Modu
9、larity is to subdivide a complex product into modules that can be independently created and then are easily used interchangeably 6, 7. There are three general fields where modularity could be implemented including modularity in design (MID), modularity in use (MIU), and modularity in production (MIP
10、) 8. MID involves stan-dardizing basic structural units which perform specific functions, thus facilitating flexible assembly of various products 9, 10. MID can reveal product structure, namely the relationship among different products. Related products are termed product family and include both bas
11、ic and specific functions. Developing product families offers benefits in terms of multi-purpose design and thus reduces production costs 11, 12. MIU is consumer-driven decom-position of a product with a view to satisfying the ease of use and individually. MIP enables the factory floor to pre-combin
12、e a large number of components into modules and these modules to be assembled off-line and then brought onto the main assembly line to be incorporated into a small and simple series of tasks.MID has been broadly applied to numerous areas and has exerted significant effects in terms of cost reduction
13、 and design diversity 13, 14. However, there is limited empirical research that has applied modular design to molds 1518. This study thus aims to reduce mold development time by applying modular design and develop a standard operation procedure for designing beverage-container injection molds, which
14、 are characterized by scores or even hundreds of components.2.General procedures of designing injection moldsBasically, an injection mold set consists of two primary components, the female mold and the male mold. The molten plastic enters the cavity through a sprue in the female mold. The sprue dire
15、cts the molten plastic flowing through runners and entering gates and into the cavity geometry to form the desired part. Sides of the part that appear parallel with the direction of the mold opening are typically angled slightly to ease rejection of the part from the mold. The draft angle required for mold release is primarily dependent on the depth of the cavity and the shrinkage rate of plastic materials. The mold is usually designed so that the molded part reliably remains on the male mold when it opens. Ejector pins or ejector plate is placed in either half of the mold, which pushes the
