Industrial thermocouple is widely used in plastic industry

In the past few decades, plastic industry has developed to a considerable scale of the country's leading industry. The material in the transportation, aerospace, electronics and transportation has significant importance in different areas of activity. Per capita consumption is growing fast. Polymer technology, processing machinery, professional technology and cost efficiency made constant progress and development are rapidly replaced plastics in different areas of the typical materials. Make plastic top industrial thermocouple played a substantial role. Industrial thermocouple by helping to soften polymer plastic processing, in order to shape it into the required shape, and inevitably into the commonly used products. Therefore, thermocouple in the plastics industry:

with thermocouple, thermocouple tube and ribbon thermocouple is usually used in the plastics industry. Steel screw plug and flange thermocouple is usually used in lubricating oil, heavy oil and light oil, wax and mildly corrosive liquid and low flow gas heating ( Such as butane, propane or natural gas) 。 Bag molding machine drum type thermocouple used to help sealed plastic bags, and control will be necessary to protect plastic thin layer from the melt. Using thermocouples and precision digital controller can also be used to maintain each application target temperature. Some manufacturers use insert steel or aluminum mold surface of the heating tube type thermocouple widespread. Aluminum or steel is an alloy of good, because they are at much faster than other materials distribution of heat.

now let's take a look at the thermocouple process involved:

& bull; Blow molding ( BrE molding) :

blow molding is used to form hollow plastic parts. This is a kind of commonly used for molding of glass bottle manufacturing process. Blow molding has three main types: extrusion blow molding, injection blow molding and injection stretch blow molding. Tempsens distribution and provides thermocouple temperature sensor and control solutions, for all kinds of blow molding applications provide long service life.

• Out:

plastic extrusion is the raw plastic melting and forming process of continuous profiles. Extrusion production piping/tubing, weather stripping, fence, deck railing, window frame, plastic film and sheet, thermoplastic coating and wire insulation.

the process will first hopper in the plastic ( Particles, particles, chip or powder) From the hopper into the extruder barrel. Material mechanical energy produced by rotating the screw and the thermocouple gradually melt along the barrel. And then to press the molten polymer into the mold, the mold will be polymer forming for the shape of the hardening in the cooling process.

the reliability, accuracy and high performance is the best extrusion process of a number of factors, these features can be found easily in the recommended industrial thermocouple. Beyond control, historical documents has become all kinds of necessary conditions for OEM or end user applications, to comply with all kinds of policies. Tempsens provide custom thermocouple, sensors and control solutions, can provide rapid thermal response for various extrusion application, consistent temperature accuracy and long service life.

• Injection molding injection molding:

refers to the material through the heating injection molding mold to rubber or plastic products. This process is the most common plastic manufacturing all kinds of products. It USES different thermocouple and its control equipment for various applications. Injection molding machine using nozzle thermocouple or drum type thermocouple will help polymer into the final product. Thermocouple and precision digital controller is used to keep the reference temperature. Thermocouples inserted steel or aluminum mold, can quickly heat to the large surface area. Barrels of thermocouple is suitable for the need of higher temperature and more strict tolerance. Design for injection molding applications, engineers and thermocouple, sensors and control solutions.

• Thermoforming:

thermoforming is heating thermoplastic material and the process of forming in the mold. Hot forming the thermocouple should be strong radiation thermocouples, temperature sensor and control solutions. Meet the most demanding thermoforming applications, such as vacuum forming, auxiliary molding pressure, drape and pressure molding.
