Why Use Nexthermal Heating Elements for your Plastic Application?

  • Decrease cycle time and incease throughput
  • Improve consistency and product quality
  • Reduce maintainence costs
  • Maximize process efficiency with thermal analysis
  • Lower scrap rates
  • Decrease down time
  • Optimize an existing system to process a wider range of plastics

Optimize Your Plastic Manufacturing Process

Nexthermal Engineering services can thermally analyze key process areas to identify where problems may exist. Many times the resolution is relatively easy just by simply identifying and selecting the right heater configuration for your application.  Or, it may need thermal analysis to pinpoint the root cause.  Either way, the most expensive option is to live with it.  If it is a thermal issue, Nexthermal will help you resolve the problem.

Nexthermal Solutions

Flat Coil Heater

Flat Coil
  • Bendable cold section
  • Wind-from-stock available to ship same day in heated lengths ranging from 10.5″ up to 86.6″
  • Comes standard with 40″ Teflon leads. Other lead protection options available include fibreglass, braided metal, iron, copper, nickel, or flexible armor sleeving

Mini Coil Heater

  • Extremely flexible cold section
  • Pressed on sheath is 20% more efficient than other mini coil heaters in most injection molding applications. Designed for temperatures exceeding 600 ºF
  • Moisture resistant transition head is ideal for high humidity applications and protecting against oil and contaminants
  • Option to integrate external J or K thermocouple

Nextflex

Nextflex Screw Terminal (Standard) Connector
  • For operating temperatures up to 700 ºF
  • In stock and ready to ship in 6.5mm, 8.0 mm, and 8.5 mm heater sizes
  • Comes standard with screw terminal tip, but also available with Plug-n-Heat connection, spade terminal, or installed with our lead adapter kit.

Axial Clamp

Coil Heater Assemblies - Axial Clamp Square
  • Axial design suited for front load heater assembly
  • Uniform heating in flow channel through precise winding pattern
  • Unique 5-piece clamping design engineered for best clamping mechanism
  • Easy installation and removal with an Allen wrench
  • ±2% wattage tolerance allows one thermocouple to control multiple heaters

Constrictor Thermal Retainer

Constrictor Attachment
  • Keep your coil heaters pressed firmly about injection molding nozzles for ideal heat transfer and accurate thermocouple reading. 
  • Tip temperatures measure over 100 ºF hotter compared to open coil.
  • 0.5″-5.5″ in stock. Custom sizes available

Hotlock

Coil Heater Assemblies - Hotlock Square
  • Fast and easy installation
  • Fine pitched threads deliver more heat toward the tip and smaller net diameter allows for closer drops
  • The increased tip temperature allows you to use higher wear-resistive materials than Beryllium copper tips

Coiled Heater Pressed in Brass

Coil Heater Assemblies - Pressed in Brass Square
  • 8% faster response and extended thermocouple life
  • The machined path enables exact repeatability of the heat profile and a more precise thermocouple placement.
  • Ideal for engineering grade applications

Sensors

Sensors
  • Engineered with precise tip placement for faster, more accurate temperature sensing
  • Can be custom built to your specific size and length requirements
  • Designed for moisture-resistance applications

Maxi Coil Heater

  • 4.6 x 8.6 profile
  • Available with optional thermocouple
  • Maxi coil can be incorporated into sealed inside ID/OD assemblies
  • Tightens to a nozzle with a clamping strap
  • Available with optional 480 V
