Ceramic Strip Seamless Strip heater

Ceramic Strip Heaters

The PTSHEAT Ceramic Strip Channel Heaters are stainless steel strip heaters which provide clean, dependable heat with sheath temperatures up to 649°C (1200°F) and watt densities up to 40 Watts per square inch.  Because of the seamless stainless steel sheath, these ceramic-insulated strip heaters are dimensionally stable in milled slots.  They can also be used in any number of applications requiring bolt-on heat.  Channel Strip Heaters are Conductive heaters and must have excellent contact with the part being heated for good thermal transfer.  You will also need to have a Thermocouple located close to the heater in your heated block to monitor the temperature of your heater and part.  Proper control is important for best heater life.

Ceramic heaters are known for their high-temperature capabilities and durability. They are often used in applications that require extremely high mold temperatures, such as in the production of certain types of plastics or specialized processes. They can be inserted into the mold to ensure the plastic material remains at an elevated temperature.

Importance: For specific applications, maintaining high mold temperatures is critical to the quality and performance of the molded parts. Ceramic heaters ensure that the mold remains at the desired temperature throughout the injection molding cycle.

(For specific applications, correctly rated elements should be used to prevent overheating and to ensure long life)



Ceramic Strip Heater CONSTRUCTION: 

1.Seamless stainless steel sheath
2. Post terminals
3. Ceramic element support
4. Element wire situated close to outside surface for maximum heat transfer and minimum internal temperature while preserving good dielectric qualities
5. Magnesium oxide packing
