A system for manufacturing last-based equipment for direct injection production of footwear and a method for manufacturing footwear

Abstract

The invention relates to a system for manufacturing equipment for a direct injection production (DIP) of footwear, said equipment comprising moulds (40) configured for direct injection production of footwear, wherein said system comprises -a design facility (10) located at a design facility location, wherein said design facility (10) provides a footwear design, -a mould manufacturing facility (12) located at a mould manufacturing location for manufacturing a mould (40) corresponding to said footwear design, said mould being configured for direct injection moulding of a sole part of said footwear, and -at least one footwear manufacturing facility (20) located at a footwear manufacturing location for manufacturing footwear according to said footwear design, utilizing a last (50) corresponding to said footwear design and said mould (40) corresponding to said footwear design, wherein last descriptive data relating to said last (50) corresponding to said footwear design are provided, and wherein said last descriptive data are communicated to said at least one footwear manufacturing facility (20) for manufacturing of said last (50) at said footwear manufacturing location or wherein said last (50) is manufactured at a last manufacturing facility (16) located at a last manufacturing location, based on said last descriptive data, and transported to said at least one footwear manufacturing facility (20).

Description

technical field [0001] The invention relates to a system for manufacturing equipment for direct injection production (DIP) of footwear. Background technique [0002] Shoe manufacturing is often a mass production process that includes custom-made equipment for production. [0003] The shoe sole may be attached to the upper by, for example, direct injection molding, where the injection mold is typically manufactured, for example, from aluminum which may be CNC cut to define the mold cavity. The method of making molds is time consuming and expensive due to the relatively expensive equipment required. Additionally, designing a new shoe line often involves multiple adjustments before the finished shoe line is ready for production, and here a separate mold is required for each size and orientation of the shoe. [0004] Preparing equipment such as molds for shoe production is typically a process involving several locations, such as a design facility providing shoe designs, a last...

Problems solved by technology

Production may require a relatively long running-in period because, for example, the various locations are located far from each other and due to the time-consuming transport of the corresponding tools, such as molds and shoe lasts, this running-in period may be affected by the Any necessary corrections to the device are extended

Furthermore, the costs involved in the initiation of new footwear designs may thus be relatively large
