Polyshot

What Polyshot does

Polyshot Corporation, Inc. is a US-based precision manufacturer of hot runner systems for plastic injection molding, founded in 1989 by Lou Borrelli and headquartered in West Henrietta, New York. The company's product portfolio centers on five lines: integrally heated sprue bushings (including the Conan sub-six-second cycle series and Direct Gate pinpoint series), pre-engineered hot runner manifold systems, self-contained multitip modules, single nozzle valve gate systems built around the proprietary Accutrak Technology, and temperature controllers (the in-house Firebox single-zone closed-loop controller plus integrated Gammaflux multi-zone controllers). Underlying technology differentiators include Accutrak valve gating for burn-free gates and rapid color changes, proprietary plate fusion flow paths without sharp corners, an in-house vacuum brazing service for conformal cooling mold cores, and Auto-Tuning PID temperature control.

The company monetizes through direct, quote-based hardware sales of hot runner systems to injection molders and mold builders, supplemented by professional vacuum brazing services (1-2 week turnaround). Pricing is opaque and contract-driven, with quotes typically delivered in 1-2 business days and stocked spare parts supporting fast delivery. Polyshot serves six named industry verticals — automotive, medical, caps and closures, consumer goods, electronics, and pet products — with the pet-vertical reinforced by the 2019 acquisition of Polyshot by Redbarn Pet Products, under which Polyshot continues operating as a separate business unit with Borrelli remaining as General Manager. A 2025 exclusive US partnership with Germany's WITOSA added 3D-printed additive-manufactured hot runners to the product surface, while SQF certification of the West Henrietta facility supports food-contact applications. Distribution is exclusively direct-sales and domestic, with no public pricing, no disclosed financials, and no venture or institutional funding events on record.

Products and services

• Heated Sprue Bushings Integrally heated sprue bushings with single heater design ensuring uniform heat profile and thermocouple sensing directly at the point of melt flow control; profile-wound single heater encased in removable tapered stainless steel sleeve with hardened tool steel body. Standard offering for over 30 years serving medical, consumer, automotive, and recreation industries.
• Conan Hot Sprue Bushing Series Specialized hot sprue bushings designed for molding very small parts using glass-filled LCPs, nylons, and engineered resins. Designed for sub-six second cycles with no drooling, stringing, or freeze-offs. Used extensively in high-precision electrical connector applications.
• Direct Gate Hot Sprue Bushing Series (P, PR series) Pinpoint gate design bushings (P and PR series) providing absolute minimum gate vestige. Gate well is machined directly into mold cavity by the mold maker. Features field-replaceable tips constructed with highly thermally conductive material.
• General Purpose Hot Sprue Bushing Series (G series) Thin reverse taper sprue design bushings (G series) commonly used when small sprue formation is acceptable. Highly resistant to wear when processing filled materials. Sprue is approximately 3/8 inch long and weighs less than half a gram.
• Hot Runner Manifold System Pre-engineered hot runner system shipped fully assembled, tested, and ready to bolt directly onto an injection mold. Features proprietary plate fusion technology for smooth material flow paths without sharp corners, balanced flow through layered systems, and in-house vacuum brazing process. Compatible with multiple nozzle types for diverse molding applications.
• Valve Gate Nozzles (M10VG, M11VG, M15VG) Hot runner nozzles that eliminate gate vestige for direct gating into molded parts without leaving marks. Features field-replaceable tips. M10VG handles parts up to 5g, M11VG up to 30g, and M15VG for parts 30-125g. Valve pins are actuated pneumatically or hydraulically.
• General Purpose Nozzles (G-050M, MS75-G) G-050M and MS75-G nozzles commonly used when small sprue formation is acceptable. Constructed of hardened tool steel for high wear resistance. Can be machined for cold runner system gating with .188 radius accommodation.
• Multitip Systems (P-Series and PL-Series) Self-contained hot runner modules allowing precision injection molders flexibility in mold design, manufacture, and operation. Can be used standalone or mated to a Polyshot Hot Runner Manifold for 8, 16, 32, or more cavity molds. P-Series and PL-Series available with 2-8 tips each, providing fully balanced material flow and equal shot-to-shot repeatability.
• Single Nozzle Valve Gate System Self-contained pneumatic direct valve gating system housed entirely within the locating ring. Delivers 400 lbs valve pin force for processing densely filled and unfilled commodity resins. Features Polyshot Accutrak Technology for quick color changes, reduced waste, and downtime. Entire assembly is contained within the locating ring with no cams or levers. Available in M11, M15, and M20 series.
• Firebox Temperature Controller (Model 3601) Closed-loop single-zone temperature controller with Auto-Tuning PID function that precisely matches controller algorithms to the hot runner system. Interfaces with Heated Sprue Bushing, Multitip System, and Bank System. Features 208-240VAC operation, Type J thermocouple, 32-1382°F control range, ±0.1% control accuracy, and burst fire relay system.
• Vacuum Brazing Services Mold bonding service using vacuum furnace brazing technique for fusing multi-component mold cores and cavity assemblies, particularly for conformal cooling. Creates internal flow paths that withstand high injection pressures. Works with H-13, 420 stainless steel, and S-7 materials. Also offers active metal brazing for dissimilar materials and vacuum diffusion bonding. Typical 1-2 week turnaround.
• Pneumatic Sequencer 3700 PS Pneumatic sequencer for operating the Single Nozzle Valve Gate. Operates on 120VAC with simple time-based operation. Allows the valve gate pin to open and close based on a timed sequence initiated by a closed loop signal from the mold or molding machine.

Directly competes with Polyshot in hot runner systems supplied to high-cavitation molders worldwide, with substantially larger scale and broader system-level offering.
• Mold-Masters: Pioneer in hot runner technology (founded 1963), now part of the Milacron molding business within Hillenbrand. Sells valve gate, manifold, and temperature control systems directly competing with Polyshot's product lines across automotive, medical, and packaging.
• Synventive Molding Solutions: A Barnes Group company specializing in hot runner systems for injection molding across consumer, automotive, and medical applications. Closely comparable product portfolio (manifold, nozzles, valve gates, controllers) competing for similar mold builder customers.
• INglass (EWIKON): Italian-headquartered hot runner specialist operating the EWIKON brand, with strong positioning in medical and technical polymers. Directly competes with Polyshot's valve gate and multitip systems for precision medical and consumer electronics applications.
• Yudo Hot Runner Systems: Korean hot runner manufacturer selling valve gate, side gate, and manifold systems globally. Competes with Polyshot on price-sensitive injection molding applications and has been expanding US distribution footprint.
• Incoe Corporation: US-based hot runner manufacturer offering valve gate, edge gate, and manifold systems. Direct North American competitor with similar product scope to Polyshot, serving automotive, medical, and consumer goods molders.
• Günther Hot Runner Technology: German specialist in hot runner systems emphasizing precision temperature control and high-cavitation layouts. Competes with Polyshot on technical applications requiring tight process stability, particularly in medical and thin-wall packaging.

Broad incumbents

• Milacron (Hillenbrand Molding Solutions): Global injection molding machine and systems incumbent now within Hillenbrand, bundling hot runners (via Mold-Masters) with presses, auxiliaries, and services. Indirect competitive threat to Polyshot via OEMs that prefer single-vendor tooling solutions.
• Wittmann Group: Austrian injection molding equipment supplier offering robots, auxiliaries, and tempering alongside its machines. While not a pure hot runner specialist, it shapes mold builder purchasing decisions globally and is a relevant incumbent reference for Polyshot's customer environment.
