We are Kol-Heater (Kolkata Heater), a leading industrial heater manufacturer based in Kolkata, delivering high-performance small injection molding machine heater solutions to machine manufacturers and processors across India. Our heaters are engineered for compact injection molding machines where thermal accuracy, energy efficiency, and process stability are essential for production success.
Operating from our manufacturing unit at 309 Rabindra Sarani, Kolkata – 700006, we supply durable, long-lasting industrial heaters nationwide. Our focus is delivering uniform heating performance that ensures reliable molding results in precision plastic processing applications.
Engineered Heating for Small Injection Molding Machines
Small injection molding machines require tight temperature control due to limited barrel capacity and sensitive processing parameters. Our small injection molding machine heaters are built to provide:
- Fast thermal response
- Uniform heat distribution
- Reduced heat loss
- Stable operating temperatures
This level of control helps manufacturers maintain consistent melt viscosity, dimensional accuracy, and repeatable part quality.
Mica Band Heater for Compact Molding Units
Our mica band heaters are widely used in small injection molding setups because of their compact design and efficient heat transfer. Built using nickel-chromium resistance wire, high-grade mica insulation, and a stainless steel outer cover, these heaters are ideal for temperatures up to 350°C.
Key advantages:
- Rapid heat-up capability
- Tight clamping for better barrel contact
- Cost-effective solution
- Space-saving design
These heaters are particularly effective in the middle heating zones of small barrels where balanced heat transfer is critical.
Ceramic Band Heater for High-Temperature Applications
For advanced processing requirements, our ceramic band heaters deliver superior performance through ceramic fiber insulation and optimized heating element placement.
Features include:
- Operating range up to 450°C
- Reduced power consumption
- Lower surface watt density
- Long operational lifespan
Ceramic heaters are ideal for engineering polymers such as polycarbonate, nylon, ABS, and PPS, where stable heating through the middle barrel section is essential to prevent material degradation.
Nozzle Heater for Accurate Melt Flow
The nozzle heater ensures consistent melt temperature at the injection point. Our nozzle heaters prevent common issues such as:
- Freeze-off
- Drooling
- Flow irregularities
Available in mica, ceramic, and mineral insulated (MI) designs, they deliver uniform heating around the nozzle, ensuring smooth plastic flow into the mold.
Key Features of Our Small Injection Molding Machine Heaters
Our heaters are designed with performance-focused construction:
- High dielectric strength insulation
- Precision-engineered resistance coils
- Stainless steel sheathing
- Uniform temperature coverage
- Corrosion-resistant materials
- Optimized watt density
These design factors provide process reliability and extended heater service life.
Advanced Temperature Control Compatibility
We ensure seamless integration with modern temperature control systems:
- J-Type thermocouples
- K-Type thermocouples
- RTD sensors
- PID controllers
Accurate monitoring across barrel zones — including the middle heating area — prevents overheating and maintains polymer quality.
Energy Efficient Heating Technology
Energy savings play a vital role in modern manufacturing. Our heaters are designed for:
- Reduced radiant heat loss
- Better insulation retention
- Optimized electrical consumption
- Faster thermal recovery
This ensures lower operating costs without compromising production performance.
