Overview
The Polyshot Manifold System is an exceptional, pre-engineered hot runner molding package, optimized for the injection molding industry. This hot runner is shipped fully assembled, tested, and primed to bolt directly onto the mold. It is also offered as a standalone hot runner manifold unit for moldmakers who prefer to build their own hot half plates.
The Polyshot hot runner utilizes heated components, specifically replaceable flexible tubular heaters. These heaters are designed to fit the hot runner’s grooves without needing special tools or fixtures. They can be replaced by the customer in the field if necessary. Each nozzle in the hot runner is heated and controlled by its individual heater and thermocouple. The thermocouple is positioned close to the nozzle end, enhancing gate temperature control and shot-to-shot consistency.
Hot runner technology used in the Polyshot system ensures manifold flow balancing through layered manifold construction (8 drops or more) and our in-house vacuum brazing technology. This proprietary technology allows large, sweeping arc flow channels with gradually changing diameters to be created. Moreover, it enables the use of hardened tool steel for the hot runner manifold, ensuring longevity even with filled resins.
Description
Nozzle alignment: The Polyshot hot runner system is designed to accommodate stress-free thermal expansion. The hot runner manifold’s center is fixed in the mold by the nozzle interface engaged to the top clamp plate and a dowel pin fitting into the manifold support plate. As the hot runner heats up and expands, it can slide across the top of the nozzle seats. When fully heated, the feed holes in the hot runner align perfectly with the feed holes in the nozzles.
Flow channels: Our hot runner technology uses proprietary plate fusion technology to provide smooth material flow paths without holding up areas or sharp corners. All our manifold systems for hot runners are designed to be fully balanced. Polyshot’s plate fusion technology is particularly beneficial in family molds or typically unbalanced hot runners (like 12 cavity molds). This hot runner technology allows flow channel sizes in the hot runner to be changed without compromising quality or balance. This feature isn’t achievable with a standard turn plug design
Details
Thermal expansion: The illustration above demonstrates the process of thermal expansion as the hot runner system heats up. All thermal expansion calculations are considered by Polyshot’s engineers during the design of the hot runner system, freeing customers from this concern.
Nozzle sealing: Nozzle sealing in the manifold is achieved both mechanically and thermally. The mechanical seal is accomplished by bolting each nozzle to the hot runner using two socket head cap screws. As the system heats up, the thermal expansion across the hot runner components allows a predetermined amount of preload on the nozzle seat. This combination creates a reliable, trouble-free seal.
Electrical requirements: All Polyshot manifold systems for hot runners operate at 208 to 240 VAC. All nozzles draw a maximum of 2 amps, and the maximum draw of any single zone is 15 amps. The total amp draw in the hot runner is determined by the number of nozzles required and the size of the hot runner manifold.
This Polyshot hot runner system is an excellent solution for the injection molding industry, offering a balance of quality, performance, and dependability.
At Polyshot, we also offer vacuum brazing services to interested mold-building customers. The typical turnaround time for this process is about 2 to 3 weeks. Send us an email to sales@polyshot.com for more details.
10M Pinpoint Nozzle
Description
10M Pinpoint Nozzle styles afford the absolute minimum gate vestige possible. They are used when it is necessary to gate directly into the part being molded. The pinpoint nozzle features a field replaceable tip that can be easily changed by the customer if necessary. It performs well when processing unfilled resins. Hardened tip inserts are available as an option when it is necessary to mold filled resins.
When using the pinpoint nozzle, all necessary tip clearances are machined into the mold cavity by the customer. This method allows only a small pinpoint mark to be left on the part after molding.

G-050M General Purpose Nozzle
Description
G-050M General Purpose Nozzle styles are commonly used when the formation of a small sprue is acceptable. They are often used when processing filled materials. Because the entire flow path of the nozzle is constructed of hardened tool steel, it is highly resistant to wear. They are also used when it is necessary to gate into a cold runner system. The end of the nozzle is designed to accommodate the machining of a .188 radius through it.

MS75-G General Purpose Nozzle
Description
MS75-G General Purpose Nozzles are commonly used when the formation of a small sprue is acceptable. They are often used when processing filled materials. Because the entire flow path of the nozzle is constructed of hardened tool steel, it is highly resistant to wear. They are also used when it is necessary to gate into a cold runner system. The end of the nozzle is designed to accommodate the machining of a .188 radius through it.
