Mold components Spark Industries has expanded its product line with integrally heated sprue bushings. The sprue bushings are made of H13 full hard tool steel, and are available with a standard head radius of 0.5-inch or 0.75-inch radius head, as well as custom sizes upon request. Replaceable type-J thermocouples are close to the flow channels.
What’s new? The sprue bushings.
Benefits Superior heat transfer, and the ability to process a wide range of resins. The sprue bushings provide minimum pressure loss and allow for rapid gate freeze, thanks to the design of their flow channels, which terminate in a reverse taper gate. Gate options include extra stock for machining applications, or a euro-style extra stock with a reduced gate diameter, which can be used in restricted areas.
