Mica Band Heater For Plastic Injection

Description

Mica band heater is to convert electrical energy into heat energy for heating objects. It is a form of electrical energy utilization. Compared with general fuel heating, electric heating can obtain a higher temperature (such as arc heating, the temperature can reach more than 3000 ° C), easy to achieve automatic temperature control and remote control.

The heated object can be kept in a certain temperature distribution as needed. Mica band heater for plastic injection can directly generate heat inside the heated object, so the thermal efficiency is high, the heating speed is fast, and according to the heating process requirements, the overall uniform heating or local heating (including surface heating) can be achieved, and it is easy to achieve vacuum heating.In the process of electric heating, the waste gas, residue and smoke generated are less, which can keep the heated object clean and does not pollute the environment. Therefore, electric heating is widely used in production, scientific research and testing fields.

The outer layer of the mica band heater is made of high quality stainless steel for conduction heating layer,it can be machined according to customer requirements into rings, plates, and various special-shaped products. The surface load is normally in line with 2.5-3 watts per square centimeter, and the customer should adopt an automatic temperature control system according to the required power range to maintain normal power and protect the service life of the band.

Due to the use of stainless steel and mica as raw materials, mica band heater for plastic injection is not limited by the size ,it can be used for small specifications of the nozzle heating, also be used for heating on the plastic machine barrel.

It is manufactured with a stainless steel cover and fiber insulated to prevent heat loss, making them highly energy efficient and reducing operating costs. The interlocking ceramics make these mica heater flexible, less prone to expansion problems and with a good thermal conductivity, the fitting around a barrel is less critical than a mica band. Mica band heater is easy to install and have a long functional life.

In order to ensure its normal operation and extend its service life, regular maintenance and maintenance of the mica heater is essential. The following are a few key points to pay attention to in the maintenance of mica heaters:

At first, regular cleaning of ash accumulation on mica sheets and metal sheets is an important step in the maintenance of mica heaters. Ash accumulation will not only affect the heating effect, but also may lead to uneven heat distribution inside the heater, resulting in damage to the heater.

Secondly, checking the power supply and line of the mica heater is also a link that cannot be ignored in the maintenance process. The normal operation of the power supply and line directly affects the stability and safety of the heater. During the inspection process, attention should be paid to whether the power plug and line connector are loose or damaged, and whether there is leakage. Once an abnormal situation is found, it should be handled in a timely manner to avoid greater security problems.

In addition, checking whether the shell of the mica heater is damaged and cracked is also an important part of the maintenance process. The integrity of the heater shell is very important for its insulation performance. If the shell is damaged or cracked, it may not only affect the heating effect, but also lead to safety hazards such as leakage. Therefore, during the maintenance process, the integrity of the heater shell should be carefully checked, and once damaged or cracked, it should be replaced or repaired in time.

Advantage

Mica heating element/mica heater element has strong corrosion resistance. The mica heater is securely enclosed in the insulating layer, which can effectively resist the corrosion of various chemical gases and chemical solutions, and also has the property of particle radiation resistance.

The circuit system is tight. The mica heating element can combine the fast heating circuit, the insulation circuit and the temperature control circuit, so that the heating element can realize automatic control.

Accurate temperature control, small thermal inertia. Temperature error 2%.
