EXAflow gate inserts are standardized components for tunnel and rear surface gating applications in plastic injection moulding. Available in diverse types and models, with different gate diameters, these products cover the broadest possible range of requirements. Our gate inserts save you time and costs by relieving you of the need to fabricate your own sprue gating systems. Rely on our proven modular technology successfully employed by an ever growing clientele.

For rear surface gating of small-to-medium sized mouldings. Supports gate diameters up to 1.8 mm and shot weights up to 100 g per insert. Suitable for all common non-reinforced plastic types.

For tunnel gating of medium-to-large sized mouldings. Supports contouring to a depth of 11.5 mm. Suitable for gate diameters up to 3.5 mm and shot weights up to 1,200 g per insert. Available types are GXK-1, GXK-2 and GXK-3. Suitable for all common plastics, including reinforced types (e.g., PA comprising 50% glass fiber).

For tunnel gating of small to medium-sized mouldings along a flat parting line. The raised head ensures concealed de-gating at the injection point. Available in 10, 12 and 14 mm sizes with 0.8 to 2.4 mm gate diameters.

For tunnel gating of small to medium-sized mouldings along a flat parting line. The raised head ensures concealed de-gating at the injection point. Rectangular design, available in 10 x 8 mm, 12 x 10 mm and 14 x 12 mm sizes with 0.8 to 2.4 mm gate diameters.

For tunnel gating of small to medium-sized mouldings contoured in the gate area. Konturflow gate inserts can be machined to a depth of 3 mm and are available for gate diameters up to 1.7 mm.

For tunnel gating of small, thin-walled components. Designed without head, these models are suitable for use on components with very low wall thicknesses. Ultra-compact design (10 x 5 mm), for 0.5 to 1.1 mm gate sizes.

For rear surface gating of small to medium sized mouldings. Supports gate diameters up to 1.8 mm and shot weights up to 200 g per insert. Available types are GMK-1, GMK-2 and GMK-3. Suitable for all common plastics, including reinforced types.

For tunnel gating of small, thin-walled moldings. This gate insert has a closed gate diameter and is therefore suitable for the use of low article weight and for very thin-walled moldings. Dimensions: 10x5x22 mm, Material: 1.4028 (420W).
