【正文】 bly [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) [8]. MID involves standardizing 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 basic and specific functions. Developing product families offers benefits in terms of multipurpose design and thus reduces production costs [11, 12]. MIU is consumerdriven deposition of a product with a view to satisfying the ease of use and individually. MIP enables the factory floor to prebine a large number of ponents into modules and these modules to be assembled offline 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 and design diversity [13, 14]. However, there is limited empirical research that has applied modular design to molds [15–18]. This study thus aims to reduce mold development time by applying modular design and develop a standard operation procedure for designing beveragecontainer injection molds, which are characterized by scores or even hundreds of ponents. procedures of designing injection moldsBasically, an injection mold set consists of two primary ponents, the female mold and the male mold. The molten plastic 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 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 finished molded product or runner system out of a mold. The standard method of cooling is passing a coolant through a series of holes drilled through the mold plates andconnected by hoses to form a continuous pathway. The coolant absorbs heat from the mold and keeps the mold at a proper temperature to solidify the plastic at the most efficient rate. To ease maintenance and venting, cavities and cores are divided into pieces, called inserts. By substituting interchangeable inserts, one mold may make several variations of the same par
