Kudos to HEATING SYSTEMS, for its contribution in Plastic Industry

In the last few decades, the Plastic industry has grown to the status of one of the leading sectors in the country as a matter of fact, the whole world with a sizable base. The material is gaining notable importance in almost every sphere of activity like transport, aerospace, electronics, transportation & FMCG products and the per capita consumption is increasing at a fast pace. Some of the continuous advancements and developments in polymer technology which are to be given the credit for the rising status of plastics in our daily lives are:

  • Processing machineries
  • Expertise
  • Cost effective manufacturing

Plastic is a material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be molded into solid objects. Apart from malleability, other features like, low cost, ease of manufacture, versatility, and imperviousness to water, plastics are used in a multitude of products of different scale, from paper clips to spacecraft. It has prevailed and is fast replacing the traditional materials, such as wood, stone, horn & bone, leather, metal, glass, and ceramic, in some products previously left to natural materials.
For plastic to reach such great heights, Industrial heaters or Heating Systems have played the substantial role. These heating systems help in the processing of plastic by softening polymers in order to shape it into the desired form and inevitably into the products usually used. Hence, selecting the right equipment can aid the goal of higher productivity and greater yields.
Role of Heating Systems in Plastic Industry:
Heating systems are made of various heating equipments like Band heaters, Tubular heaters, flange heaters, cartridge heaters, and Strip heaters which are commonly used in the plastics industry. Thermocouples and precise digital controllers are also used to maintain target temperatures for each application.
Following are the plastic manufacturing processes where Heaters are involved:

  • Blow Molding: Process generally used for forming glass bottles.
  • Extrusion: Process in which raw plastic is melted and formed into a continuous profile.
  • Injection Molding: Refers to shaping of rubber/plastic articles by injecting heated material into a mould.
  • Thermoforming: Process of heating a thermoplastic material and shaping it in a mould.

Heating systems required for these processes should be robust radiant heater, reliable, accurate, high performing, temperature sensor and control solutions.

Understanding the Concept and Importance of the Annealing

After selective heating which was the heat treatment for specific application only we are trying to trough some light on the Annealing heat treatment process. In Annealing the material under the processing is heated to particular temperature, the desired temperature is held for the defined time duration, and afterwards allowed to cool at steady rate of cooling. Annealing process is sensitive to temperature and time, depending upon the material the choice of the temperature and time is required.
Process of annealing:
The first step of the annealing is to heat the material under the processing, the temperature is raised slowly at steady rate of rise of temperature this is done achieve the equal state of the expansion with caution that the molecules should not change their state from solid to viscous liquid. The second step is to hold the temperature for the few minutes, hours to days depending upon the material so that all the molecules release their stress and pressure. The third and very important step is cooling the rate of the cooling is very critical and should be controlled accordingly to avoid 1) the creation of various temperature spotting (variation in the temperature due to complex shape or thickness of material) 2) achieve proper molecules reformation to achieve the desired flexibility and agility in the material.
Variants of the Annealing:
Below are the some variants of the annealing process:

  • Full Annealing/Conventional Annealing
  • Isothermal Annealing
  • Spheroidise Annealing
  • Re-Crystallization Annealing
  • Stabilisation Annealing
  • Stress Relief Annealing

*Variants of the annealing we will try explaining in the upcoming blogs.
Benefits of the Annealing:
Annealing heat treatment is done across several industries on various types of materials such as metals (steel, Iron etc), Glass, Plastic and Etc. to achieve following benefits of the process:

  • Reduces the inner stress 
  • Increases Ductility 
  • Increases the toughness
  • Improves the homogeneity
  • Improves the agility 
  • Improves the material structure 
  • Reduces the hardness and brittleness 
  • Improves the magnetic property 
  • Improves the appearance of the material 

We at KERONE have experience of 40 years in helping the industries with their heating needs, as the annealing is very important heat treatment and selection of the proper heating system is very critical, we at KERONE is have team of experts to help you with the your need of annealing heating system from our wide experience.
