Abstract
A footwear molding system for direct injection production of footwear. The system includes an injection mold and a mold closing member. The mold closing member includes at least one vacuum channel. The at least one vacuum channel is connected directly or indirectly to at least one vacuum opening on the surface of the mold closing member. The mold closing member is configured for positioning at least part of a footwear upper during at least part of a direct injection production process. The at least part of a footwear upper being at least partly adhered to the mold closing member by vacuum effected by the at least one vacuum opening.

A method for manufacturing a footwear, said method comprising steps of providing a moulding system comprising:
- an injection mould, and
- a mould closing member,
- wherein the mould closing member comprises at least one vacuum channel and wherein the at least one vacuum channel is connected directly or indirectly to at least one vacuum opening on the surface of the mould closing member,
- wherein said method further comprises steps of:
- applying a source of vacuum to said at least one vacuum channel,
- positioning at least part of a footwear upper on said mould closing member, said at least part of a footwear upper being at least partly held in place by said vacuum,
- positioning said mould closing member with said at least part of a footwear upper in relation to said injection mould,
- closing said injection mould to form a mould cavity,
- injecting direct injection material into said mould cavity, said mould cavity defining a sole, and
- opening said injection mould upon curing for removal of the sole with said at least part of a footwear upper attached to the sole.
