PLASTIC industry

DOMAIN TRAINING

The Plastic industry is the most booming segment of the mechanical industry. It is slowly increasing its foot print. Did you notice it yet? Okay, let us begin with a bumper of a vehicle. Recall the kind of bumpers we see in old vehicle. Wasn’t it made of metal. Strong metal? How about today’s vehicle’s bumpers? Did you notice it to be non-metallic and flexible? It is made of plastic, which increases vehicle’s aesthetic appearance by having same look and finish as that of vehicle metallic body. During mild bump-in between vehicles, it does not leave scratch or dents, which reduces maintenance cost and chance of fights between vehicle owners. Look inside any vehicle, interior is mostly made of fancy plastic products which offer different types of textures, finish, materials and so many varieties. Consider consumer goods, like washing machine, fridge, mixer-grinder, or electronics goods, you will realize the use of plastic is predominant in each of them.

WHY PLASTIC IS SO WIDELY USED

Top 5 reasons

  1. Plastics are available in wide range of technical grades, designs, colors, and textures – It helps to make different types of plastic products for different purposes.

  2. Lower weight than most of the metallic products – It is the most important winning point for plastics, that is, less weight and sufficient strength.

  3. High flexibility – As explained above in vehicle bumper example, it helps to make flexible products, which defrost and regains its shapes, rather than attaining permanent deformation, as in case of metallic products.

  4. Ease of manufacturing – Plastic products are made by casting, which is a process of converting molten plastic into the solid plastic product. Casting gives the flexibility to make any shape, reduces the needs of after casting operations to a minimum, and therefore, reducing the manufacturing cost.

  5. Ease of assembly and maintenance – When you design any plastic product then you would reduce post casting processes to almost zero. Only assembly work will remain. Since assembly consideration are also made in the design, therefore, it is earlier to assemble plastic products and replace it during maintenance activities.

WHY SHOULD I LEARN PLASTIC INDUSTRY DOMAIN

Answer is simple, you have numerous high paying job opportunities and the industry is growing over time. In short, it provides bright career future.

 

As we advise to every student, you should select your career which is aligned to your interest to ensure success. At the same time, you should take informed decision. If you get any advice to select your career, spend some time to do research on same. Once you are convinced with verifiable information and facts then take a decision.

 

Now think about interior of a car. It is mostly made of plastic, which is fixed on BIW (Body in white, which is frame structure of the car). You would find a great utilization of the plastic part, for example, glove box, water bottle holder, coffee mug holder, coin holder, hand support, fixture to electronic equipment like music system, GPS screen, charger plug, etc. More the car is luxurious, more the features. Overall, Plastic is not only increasing aesthetic appearance, but also increasing utilization, convenience of use, convenience to manufacture, convenience to maintain, and many such benefits.

 

Suppose, you are interested in product development, you will have to consider the usage of plastic based on utilization, cost and marketability. Industry is shifting from metallic to plastic based products. Take any bike for that matter. Apart from engine, frame, fuel tank, suspension and wheel systems, everything else is made of plastic.

 

Let us take another interest areas, which is found in mechanical engineers, 3D printing. As of now (2019) 3D printing of molten metal is not yet achieved for commercial use however 3D printing of molten plastic, or similar material is being used for some time now. If you want to 3D print any prototype or any product then you must be aware about plastic domain. Isn’t it?

 

Overall, wherever you go, you will interfere with usage of plastic, then why not be an expert of same?

HOW IS THE JOB POTENTIAL

 

HOW ABOUT CAREER GROWTH

Visit Google and search for “Plastic industry jobs” You will be amazed to see number of opening in India, Europe and rest of the world. Plastic industry is a promising area of work in mechanical industry.

Plastic industry is an evergreen area of work in the mechanical industry. Therefore you can plan your career in the Plastic industry.

Why is it called Domain training

How long it takes to complete the course

Domain training is industry specific specialization training to learn about one particular area in detail to enable the trainee to start working in given area. Domain training is given to those professional who want to work on best and latest technology and grow faster in their career. At high level, domain training for Plastic industry will cover following points:

  • Basics of the Plastic industry

  • Plastic product manufacturing process

  • Plastic material characteristics and selection criteria

  • Plastic part design consideration

  • Plastic part modeling and design process

  • Plastic welding and design process

  • Manufacturing defects

  • Industry best practices

  • Drawing with tolerance and GD&T

  • Master data creation

  • Remastering, and more.

You should plan for 160 to 260 hours of training and practice, to be ready for the industry. Here 160 hours is devoted to learning of Plastic industry concepts, best practices, design approach, etc., and remaining hours are utilized for learning software and practicing for Plastic industrial exercises and projects. Based on time you spend, you can plan to learn it in 3 months to 6 months, depending on your speed and practice.
