II Hot Runner Nozzles

All specifications are subject to change without notification. The Precision Series II Hot Runner system is an exclusive medium pitch, flat gate system with the ability to process engineering and glass-filled resins without deteriorating the tips. Acceptable for crystalline and amorphous materials, this system utilizes gate diameter, gate area cooling and temperature control at the tip to optimize the part quality.Precision Series II “flat gating”™ leaves a small mark on the molded part surface (gate vestige). Thegate can be sunk into a round depression (referred to as a “recessed gate”) so that the mark does not protrude above the part surface. The Precision Series II is available with two different head styles and five gating options to suit a broad range of applications. Wear Resistant Pinpoint Tips –

Standard Pinpoint Tips –
Patent Pending Exclusive tip design exceeds minimum vestige requirements and tip life expectations. Color change capabilities are enhanced. Ideal for non-erosive commodity resins, these tips are available in 0.015” (0.40 mm), 0.030” (0.75 mm), and 0.050” (1.25 mm) tip flat diameters, to better maintain minimum vestige in parts up to 150 grams (see engineering charts 1, 2 & 3 on page 5). Sprue Tips –
Patent Pending Recommended for glass-filled and other aggressive engineering grade materials, these tips have an excellent heat profile and high wear resistance characteristics. The innovative design orients molecular flow of the material, glass fibers and fillers in a linear direction. This linear orientation reduces shear, which translates to longer tip and gate life. Available in 0.015” (0.40 mm), 0.030” (0.75 mm), and 0.050” (1.25 mm) tip flat diameters, to better maintain minimum vestige in parts up to 150 grams (see engineering charts 1, 2 & 3 on page 5). Tips can process all types of resins, from commodity to engineering grades, while maintaining optimal performance with minimal vestige. Ideal for retrofitting into existing molds that may have larger gates. Available in standard and wear resistant alloys, these tips are capable of processing up to 150 grams of low viscosity resin (see engineering charts 1,2 & 3 on page 5). Extra Stock Sprue (Nylon) Tips – Extra Stock Sprue Tips – Specially developed to process resins with narrow melt flow parameters, this tip design provides optimum control within the high temperature zones of the nozzle. Ideal for materials such as nylon and acetal, where vestige is not critical. These wear resistant tips can process 75 grams of high viscosity resin (see engineering charts 1,2 or 3 & page 5). Identical to the Standard Sprue tip, except with .512” (13mm) of extra stock at the tip, which can be machined to meet customer specific requirements. Ideal for difficult access areas in the part, or for secondary runner applications. Available in standard and wear resistant alloys, these tips are capable of processing up to 150 grams of low viscosity resin and 75 grams of high viscosity resin (see engineering charts 1,2 & 3 on page 5).

Head Options for the Precision Series
