    What is the processing temperature upper limit that I can use with my D-Max Hot Sprue Bushing?

    It depends on the application, as well as both the bushing assembly and the tip or tip assembly used. The D-Max unheated head hot sprue bushing assemblies are not recommended to be used with applications requiring greater than 480°F (249°C) melt processing temperature. If you have an application that exceeds 480°F (249°C) melt processing temperature, it is recommended to use a D-Max hot sprue bushing assembly with heated head.

    The D-Max ring-gate and point-gate tip assemblies are available with standard needles as well as wear-resistant needles. Standard D-Max needles are not recommended to be used with any filled thermoplastic, and are not recommended to be used in applications that require greater than 480°F (249°C) melt processing temperature. Wear-resistant D-Max needles can be used with filled thermoplastics (not recommended for thermoplastics that have greater than 30% filler including glass, mineral, talc, other), and are not recommended to be used in applications requiring greater than 635°F (335°C) melt processing temperature.

    D-Max sprue tips can be used with filled thermoplastics (not recommended for thermoplastics that have greater than 30% filler including glass, mineral, talc, other) and are not recommended to be used in applications requiring greater than 635°F (335°C) melt processing temperature.

    If you have an application that requires greater than 635°F (335°C) melt processing temperature, if the intended thermoplastic has greater than 30% filler, or if you would like a recommendation as to the parts best suited for your intended application, please contact your DME Customer Service Representative and you will be put in contact with a DME Technical Service Representative to review your application requirements.
