Thermal solutions for plastics & extrusion
Consistent melt temperature. Tight zone control. Zero cold starts. MAHC engineers the heating loop your extruder or molder demands.
Every gram, every degree
In extrusion and injection molding, a single cold zone means inconsistent melt — and scrap. MAHC provides matched heaters, sensors and multi-zone controllers so every barrel section tracks setpoint.
Band & Cartridge Heaters
High-watt-density band heaters for barrel zones; cartridge heaters for nozzle tips, hot runners and shut-off valves.
Multi-Zone PID Control
Single-loop and multi-loop controllers (up to 32 zones) with ramp/soak profiles, alarm logic and auto-tune.
Melt-Temp Instrumentation
Fast-response RTDs and grounded thermocouples for melt pressure/temp sensors in the barrel or die head.
Zone Control Panels
Integrated panels with SSRs, fuses and thermocouple wiring — one unit per extruder, ready to install.
Custom panel buildsWhat we heat in plastics
- Single & twin-screw extruders
- Injection molding barrels & hot-runner manifolds
- Blow molding & extrusion-blow

- Downstream: chill rolls, calender, die heating
Plastics & extrusion heating FAQ
We routinely build 8–32 zone panels. Each zone gets its own PID loop with independent setpoint, alarm and output. For larger machines, we network controllers for centralized HMI monitoring.
Yes. Send us the part number, OD, length, wattage and voltage. We match to American-made equivalents (Watlow, H&S, Thermal Corp) with the same or better watt-density and temperature rating.
Call us with the zone number, setpoint and sensor type. We can typically ship a replacement heater + matched sensor same-day, and walk you through verification remotely.
Running hot? We'll keep it there.
