Product Description

Micro Tubular Heaters for Injection Molding Heating Elements

Product Description

 

1. Micro Tubular Heaters Working Principle

Mini Micro Tubular Heaters, is a small size coil heater with smaller diameter nozzle or nozzle tip that can also be formed in grooves.

Because of its small size, mini coil heater are widely designed with a pressed on sheath, pressed into brass, or serve as the heat source for Hotlock, and Axial Clamp heaters.

The Hotlock design protects the mini coil heater with an inside, outside stainless sheath and enclosed end rings for superior durability.

Our Advantages

 

2. Advantage
Replace the external thermocouple
Proven durable heater for tight space constraints
Staggered or single transition head configurations
Profiled for more heat at the Tip

4. Micro Tubular Heaters Imported Raw Materials

a. The coil heater resistance is used German Nickel Chrome wire, can be coiled and straight.

b. The insulation material magnesium oxide powder is imported from USA; which ensures the high performance, fast response time and good unformity.


5.  Surface Treatment

Blasting and blackening surface treatment, also can provide bright surface.

7.  Coil Heater Cross Section

Based on specific requirements and applications, coil heaters are manufactured in different cross sections.
Each one is having its own advantages and disadvantages. Basically there are three types of coil heaters.
They are

Coil Heater Cross Section
Round Coil Heater Diamater	Φ3.0, Φ4.0,Φ5.0
Square Coil Heater Diamater	3.0×3.0, 3.3×3.3, 3.5×3.5, 4.0×4.0, 5.0×5.0
Rectangular Coil Heater Diamater	4.0×2.0, 4.2×2.2, 4.5×2.7
