TUTCO CONDUCTIVE
Hot Runner Components
TUTCO provides Hot Runner Components designed to deliver unmatched reliability and precision for direct feed and injection molding applications. Engineered for demanding manufacturing environments, these components ensure consistent performance and exceptional product quality. Our hot runner bushing integrates cutting-edge heater technology and thermocouple protection circuitry for precise temperature control. This ensures optimal melt flow, reducing the risk of material degradation and minimizing cycle times.
Precision Series
The New Precision Hot Runner Bushings & Nozzles are designed to run mid-size and large molded parts. Advanced heat transfer technology provides optimum performance while a unique sleeve heater design allows for easy and quick replacement. The special tip design allows the Precision to process commodity, engineering and filled resins while drastically reducing tip wear at the gate. The Precision has eleven different gating options to meet a wide range of Direct Feed or Manifold applications.
FEATURES AND BENEFITS
• Exclusive “Flat Gate”™ System - Gate vestige is minimized and each design can be customized
• Advanced Integrated Sleeve Heater - Extended heater life for easy serviceability
• Unique Wear Resistant Tip Design - Less downtime due to tip repair
• Medium and Large Pitch - The Precision can service more mid-size molds/part shot sizes
• Consistent Heat Profile - Optimum hot runner performance
• Resin Versatility - Wide range of resins can be processed for more applications
• Replaceable Tips, Heater and T/C - Easy serviceability
• Custom Designed Tip Tools - Easy replacement of all tip styles
Sprue Bushings
Our Hot Runner components feature an Integrally Heated Sprue Bushing that is uniquely designed for high performance and reliability for Manifold and Direct Feed Applications, even with the most demanding molding cycles and plastic resins. Its unique integrally heated design ensures advanced heat transfer, providing a more consistent and uniform heat profile throughout the process. Additionally, a replaceable thermocouple is strategically positioned near the melt flow channel, allowing for precise optimization of processing conditions for all types of thermoplastics. This thoughtful design ensures that your molding operations run smoothly and efficiently, no matter the challenges.
FEATURES AND BENEFITS
• Graduated Watt Density - Maintains a more uniform heat profile.
• High Refractory Insulation - Provides superior heat transfer.
• Streamlined Flow Channel - Provides for minimum pressure loss.
• Fully Sealed Construction - Maintains highest product reliability.
• Made of High Grade Alloy Steel - Increases durability and longer life.
• Replaceable Thermocouple - Allows for easy serviceability.
Machine Nozzles
Our Integrally Heated Machine Nozzle features a unique design that eliminates voids and air gaps, which often hinder the performance of traditional heated nozzle systems. With enhanced heat transfer capabilities, the Sensitip Machine Nozzle delivers superior performance and reliability, surpassing all existing nozzle designs.
A replaceable “Type J” thermocouple senses temperature adjacent to the melt channel. This accurate sensing system works in conjunction with a very uniform temperature profile to ensure superior processing of even the most critical of engineering materials.
FEATURES AND BENEFITS
• Integrally Heated Design - Provides optimum nozzle performance.
• Streamlined Flow Channel - Provides minimum pressure loss
• Fully Sealed Construction - Maintains highest product reliability.
• High Grade Alloy Steel Construction - Increases durability and longer life.
• Replaceable Thermocouple - Allows for Type “J” or “K”.
• Three Tips Styles - Available with either a .500″ or .750″ Spherical Radius, accommodate a full range of Injection Molding applications.
Flextracoil
Our Flextracoil heaters were created to heat flow-through nozzles and sprue bushings in runnerless molding systems.Available in either flat, square or round styles, the Flextracoil can be coiled evenly spaced or with distributed coils. All styles are stocked uncoiled at Tutco and are formed to customer specifications before shipping.

Yes — one of the big advantages of TUTCO’s hot runner component line is versatility. Whether you’re molding commodity plastics, engineering resins, or filled materials, the Precision series and associated bushings/nozzles are designed to support a wide range of resins and part shot sizes. Because they offer multiple gate styles, replaceable heater elements and thermocouples, and durable alloy steel construction, you can fine-tune your hot runner setup for longer life and more consistent results across different production runs.
When your mold uses a gate into the cavity, the size and shape of the gate affect things like vestige (the leftover impression on the part), flow efficiency, and how often you’ll need to service your tip. TUTCO’s exclusive “Flat Gate™” system is engineered to keep that vestige to a minimum and offer customization to meet your molding layout. The wear-resistant tip design means you’ll spend less time repairing or replacing tips—especially useful if you’re running filled resins or high-volume cycles that tend to accelerate wear.
A lot of molding issues stem from inconsistencies in temperature and flow, especially at the gate or nozzle. With TUTCO’s integrally heated sprue bushings and machine nozzles, the heater design is built into the body and the thermocouple is positioned close to the melt channel. This gives better control over the melt temperature and helps maintain a uniform heat profile. That means fewer surprises with material degradation, shorter cycle times, and more consistent part quality.
Choosing the correct component depends largely on the size of your shot, the number of cavities, the type of resin you’re running, and how cleanly you want the gate to show—or not show—on your finished part. TUTCO’s Precision series hot-runner bushings and nozzles are built for mid-size to large parts, offering multiple gate options, improved heat transfer, and replaceable tips and heaters so you can match the component to your specific mold run. This flexibility means you can select a design that handles commodity or filled resins, reduces tip wear, and supports more demanding production environments.
