This study aims to develop a method of

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,

Next, dimen-sions and specifications of each unit are standardized and a compatible interface is constructed l

5、inking relevant units. This work employs a cup-shaped beverage container to 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

6、19 23% compared with the conventional ap-proach. Meanwhile, the information 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 fam

However, developing a mold for mass produc-tion requires considering numerous factors, including product geome

8、try, dimensions, and accuracy, leading to long product development time. Introducing 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

9、 enhances product innovativeness, flexibility, and customer services 5.Modularity 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

10、in design (MID), modularity in use (MIU), and modularity in production (MIP) 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 differen

11、t products. Related products are termed product family and include both basic 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 th

12、e ease of use and individually. MIP enables the factory floor to pre-combine 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 nu

13、merous areas and has exerted significant effects in terms of cost reduction 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

14、operation procedure for designing beverage-container injection molds, which 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 p

15、lastic enters the cavity through a sprue in the female mold. The sprue directs 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 sligh

16、tly 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, whi
