Limited single head electric heating tube

Structure: A circular or plate baffle is welded to the terminal end of the single-head electric heating pipe. Purpose: Used for heating holes in molds or machine parts. So that the limiting element does not produce longitudinal displacement. Voltage: - Recommended specifications: ︿︿. The limited-type single-head electric heating tube has high wattage, short size, multiple specifications, high temperature, high accuracy of outer diameter, and is easy to heat the mold. Conventional limit type is suitable for: plastic packaging, small mold heating, analytical instruments, cigarette industry, manufacturing, semiconductor eutectic welding, die casting input channel heating and glueless injection, refrigeration effect when various gases expand, etc. .
Calculation formula for wattage of limited-type single-head electric heating tube (heating rod)

Customers can customize high-watt density heaters (/above) according to actual needs.
Precautions for customized installation
The limited-type single-head electric heating pipe itself has a high watt density. Often due to poor heat transfer, the outer pipe body is scorched black, and the internal high temperature accelerates the aging of the heating wire, causing the heating wire to break. .
. Pay attention to precision when processing deep holes in the mold. Do not drill holes at both ends, because the junction cannot be tightly sealed and there will be large pores, which will cause poor heat dissipation of the electric heating tube and uneven temperature of the heated body.
3. It should be noted that the magnesium oxide powder at the outlet end of the electric heating tube must not be exposed to contaminants and moisture in the place of use to prevent leakage. It is best to reserve it outside the mold.
