An injection molding system having a manifold element (5) carrying a melt passage (2); the manifold element (5) being connected to an inlet (3) at one end for receiving molten material and at the other end a nozzle (7) opening into a gate (21) of the mold; the manifold element (5) being heated, and spaced from relatively large bodies, such as clamped plate elements (14) or cavity plate elements (11) which are less heated, unheated or cooled by relatively thin-walled spacer members (12); the spacer members (12), having two oppositely directed bearing surfaces the one bearing against the manifold elements (5), the other bearing against said body; and a relatively thin-walled wall part (17) extending between the bearing surfaces; the wall parts (7) having a curvature to be resilient for compression and extension in the direction from the one bearing surface towards the other bearing surface.

[ I claim:] [1.] An injection molding system comprising:a spacer member; anda manifold element carrying a melt passage,said manifold element being connected to an inlet at a first end for receiving molten material and at a second end to a nozzle opening into a gate of a mold,said manifold element being heated, and being spaced from at least one of a clamped plate element and a cavity plate element by said spacer member,said spacer member comprising a thin walled, annular spacer having 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,said annular wall comprising a first resilient wall part located between the oppositely directed bearing surfaces in the form of a step or a bend part extending transversely to the general direction of the annular wall.
