HRSflow presents its small-sized SA series hot runner nozzles for injection molding small technical components with a very compact cut-out in the tool. The hot runner nozzles are suitable for injection molding technical parts with a shot weight of about 1 g and less, as well as for wall thicknesses below 1 mm. Their selectable gate versions open nozzle and valve gate are available with bushing through the cavity or gate on the cavity. The tip shape and material, the channel section and the contact surface of the end ring with the cavity are designed to have optimal thermal conditions for high flexibility in processing engineering polymers. The compact design enables a compact cut-out in the tool, and the large melt channel diameter enables the processing of highly reinforced or viscous plastics at high flow rates. The nozzle screwed on the manifold guarantees the seal at high injection pressure without requiring accuracy in machining.

The company also extends its cylinder portfolio, including compact hydraulic cylinders, which require small cut-outs in the tool and provide an increased thermal insulation due to components material and optimized contact surfaces, minimizing heat transfer to the manifold and reducing energy consumption. In addition to the basic version, a version with needle damping is also available. Further variants offer a microswitch version for the double needle end position detection, as well as an adjustable version for the possibility of compensating the position of the needle by ± 1 mm without mechanical reworking.
