Stockfitting

The following stockfitting processes are available for footwear in the Higg Product Module:

  • Cooling/Chilling should be selected when the footwear has components that are fast cooled in a cooling tunnel (such as to lower the time before delasting). The unit for this process is “per cycle,” with two parts (for one pair) modeled per cycle. If multiple components per footwear product are fast cooled, then more than one cycle should be selected.
  • Deep Well Pressing should be selected when the footwear has stock-fitted parts that are pressed together to make the sole of a shoe. The unit for this process is “per cycle,”with two parts (for one pair) modeled per cycle. Under stockfitting, only deep well pressed stock-fitted components should be added. Deep Well Pressing to attach the lasted upper and stock-fitted unit should be selected from Assembly.
  • Oven/Heat Tunnel should be selected when the footwear has components that are heated in an oven or heat tunnel (such as to dry the primer or cement after application). The unit for this process is “per cycle,” with two parts (for one pair) modeled per cycle. If multiple components per footwear product are heated, then more than one cycle should be selected.
  • UV Lighting Machine/Activation should be selected when the footwear has components that are treated using ultraviolet radiation and ozone. The unit for this process is “per cycle,” with two parts (for one pair) modeled per cycle.
  • Water Pressing should be selected when the footwear has parts that are pressed together using a water press (such as the lasted upper and the sole). The unit for this process is “per cycle,” with two parts (for one pair) modeled per cycle.
  • Painting/Staining/Coloring (e.g. Outsole edges painted, stained etc) should be selected when the footwear product has painted components. The unit for this process is “per cycle,” where each cycle is the painting required for one pair of footwear.
  • Weighting or hand building, footwear should be selected when the footwear product is modified to add fullness (bulk or weight) and/or increased stiffness. This is typically done through the addition of hand-building substances, such as starch, polyvinyl alcohol (PVA), vinyl-acetate polymers, polyurethane, thermoset resins, or acrylic co-polymers. The unit for this process is “per cycle” and each cycle represents one weighting or hand building process for a pair of footwear. Note that the process model for weighting or handbuilding currently only captures the impacts associated with mechanical processing and care should be taken when interpreting the impacts of this process.
  • Hole Punching should be selected for any hole punching of a part. The unit for this process is “per hole” and the total number of holes per pair of footwear should be specified. This process is also available in Pre-Assembly Footwear and the total holes per pair of footwear do not need to be entered twice.
  • Bottom Die Cutting should be selected for footwear where die cutting is used to cut the bottom material into the correct shape. The unit for this process is “per part” and each unit is one die cut component.
  • Buffing should be selected for footwear where a surface is sanded to obtain good adhesion or bonding. The unit for this process is “per part” and each unit is one buffed part or component.
  • Cementing/Gluing should be selected for footwear where parts are bonded by using an adhesive compound. The unit for this process is “per part” and each unit is one gluing step where two or more components become a single output.
  • Priming should be selected for footwear where a layer of primer is applied to component surfaces to prepare them for bonding. The unit for this process is “per part” and the number of parts that have primer applied to them should be entered.
  • Skiving should be selected for footwear where components have their edges reduced in thickness by slicing or scraping. The unit for this process is “per part” and each unit is one skived part or component.
  • Trimming should be selected for footwear where excess material from the outsole is trimmed off. The unit for this process is “per part” and each unit is one trimmed part or component.
  • Upper Component Die Cutting should be selected for footwear where die cutting is used to cut the upper material into the correct shape. The unit for this process is “per part” and each unit is one die cut component.
  • Washing/Cleaning should be selected for footwear where the incoming midsole is washed or cleaned to remove impurities before any stockfitting processes. The unit for this process is “per part” and each unit is one washed or cleaned part.
