A mould for manufacturing three-dimensional items, comprising a body; a lid configured to close the body; and incorporated closing and openings configured to keep the body and the lid joined during the movement thereof is disclosed. A machine for manufacturing three-dimensional items, comprising a receiving module configured to receive the mould; a conditioning module configured to receive the mould from the receiving module and act on the incorporated closing and openings in order to separate the lid from the body; and a handling module configured to receive the body from the conditioning module and enable the placement of the components of the item to be manufactured. A method for manufacturing three-dimensional items and manufacturing plant associated with the machine.

A molding process for shoes with inner lining comprises: placing a molding inner core sleeved with an inner lining in a combined external mold being preset with a semi-molded shell; performing a mold-closing action to make the semi-molded shell in the first external mold and the second external mold attach to the inner lining, respectively; and heating to vulcanize the semi-molded shell, and combining with the inner lining to produce a shoe with inner lining.

Methods of and molds for manufacturing footwear are disclosed. In one example, the method may include forming at least one molded portion adjacent to at least one non-molded portion such that part of the at least one molded portion overlaps and contacts the at least one non-molded portion, and forming the at least one molded portion to include end portions that are adjacent the part of the at least one molded portion and that extend away from the at least one non-molded portion such that the end portions do not contact the at least one non-molded portion; moving the end portions of the at least one molded portion toward the at least one non-molded portion such that the end portions contact the at least one non-molded portion; and securing the end portions of the at least one molded portion to the at least one non-molded portion.

Comprehensive wrapping and environment-friendly shoes and a production process thereof are provided. Each shoe comprises an upper and a sole. The upper includes an inner bootie and a vamp; the inner bootie includes a lining and a PU inner pad which are connected; the collars of the inner bootie and the vamp are connected, and the vamp lower edge extends to the inner pad bottom surface and is connected therewith. The making process is simple and can save sole laying and insole assembly procedures and simplify the upper marking procedure; the inner bootie enables the upper and the sole to be completely attached to a last, realizes good wearing comfort and barefoot feeling, achieves maximum sports shock absorbing and assisting function and comfortably wraps the foot. By reducing EVA & RB materials and increasing PU material, the dissolution proportion of the shoes is increased, and the shoes are more environment-friendly.

Methods and systems are provided for forming an article of footwear. In one example, forming the article of footwear includes using a perforated last during molding of a midsole of the article of footwear. The midsole may be attached to a seam of the upper of the article footwear to secure the midsole to the upper.

A system of manufacturing equipment including molds for a direct injection production of footwear. The system includes a design facility that provides a design. A mold manufacturing facility manufactures a mold for the design for molding a sole of the footwear. A last manufacturing facility manufactures a last of the design. A footwear manufacturing facility manufactures footwear according to the design. The last corresponds to the footwear design and the mold corresponds to the footwear design. The mold is a basic direct injection mold and at least partly channels injection material to a mold cavity and further accommodates direct injection mold inserts. Mold descriptive data of the mold inserts is communicated to the footwear manufacturing facility to manufacture the mold inserts, or the mold inserts are manufactured at the mold manufacturing facility based on the mold descriptive data and transported to the footwear manufacturing facility.

A footwear moulding system for direct injection production of footwear includes a supporting mould, a last, an in-mould, and an injection channel. The supporting mould includes at least an in-mould support. The in-mould is elastomeric and the in-mould includes an in-mould outer surface configured to be supported by said in-mould support. The in-mould support includes at least one support side mould and a support bottom mould.

A method of forming an article of footwear can include flowing a material into an inlet port of a last and through a plurality of interconnected channels extending through an interior of the last that are fluidly connected to the inlet port. The method can further include flowing the material from each channel, out a respective outlet port of the channel that is disposed on an outer surface of the last, and directly onto the outer surface of the last. The method can further include solidifying the material on the outer surface of the last to form at least a portion of the article of footwear.

A system of manufacturing equipment including molds for a direct injection production of footwear. The system includes a design facility that provides a design. A mold manufacturing facility manufactures a mold for the design for molding a sole of the footwear. A last manufacturing facility manufactures a last of the design. A footwear manufacturing facility manufactures footwear according to the design. The last corresponds to the footwear design and the mold corresponds to the footwear design. The mold is a basic direct injection mold and at least partly channels injection material to a mold cavity and further accommodates direct injection mold inserts. Mold descriptive data of the mold inserts is communicated to the footwear manufacturing facility to manufacture the mold inserts, or the mold inserts are manufactured at the mold manufacturing facility based on the mold descriptive data and transported to the footwear manufacturing facility.
