Injection molding system having a spacer member

A spacer member for use in an injection molding system to bridge an insulative air space between a heated manifold and an unheated member, comprising:

• an annular wall generally extending in a direction of a center line of the spacer member, and
• two oppositely directed bearing surfaces extending transversely to the center line,
• wherein the annular wall comprises a first resilient wall part located between the oppositely directed bearing surfaces shaped in the form of a step or a bend part extending transversely to the general direction of the annular wall.

A spacer member for use in an injection molding system to bridge an insulative air space between a heated manifold and an unheated member and to provide resiliency between said heated manifold and said unheated member, comprising:

• first and second annular wall elements comprised of plural, generally parallel corrugations running in a generally longitudinal direction of said first and second wall elements,
• each of said first and second wall elements further comprising a first lateral end and a second lateral end,
• said first lateral ends being fixed to said unheated member and said second lateral ends being fixed to said heated manifold so that resiliency is provided between said heated manifold and said unheated member by deflection of said first and second annular wall elements in a direction of compression.
