What is plastic in mechanical engineering?

What is plastic in mechanical engineering?

A plastic is a polymeric material that is in a semi-liquid state, having the property of plasticity and exhibiting flow. Plastics engineering encompasses plastics material and plastic machinery. Plastic Machinery is the general term for all types of machinery and devices used in the plastics processing industry.

What is plastic product design?

Plastic product design is a multidisciplinary professional task. It blends the understanding of your customers’ needs, the enhancement of their experience regarding those needs, and the transformation of that idea into something tangible made of plastic.

What are mechanical designs?

Mechanical design is to design parts, components, products, or systems of mechanical nature. For example, designs of various machine elements such as shafts, bearings, clutches, gears, and fasteners fall into the scope of mechanical design. Functions are specified for what a product can fulfill.

How do you design plastic components?

Here are 8 important factors to consider to meet your plastic part design goals for a successful production process.

  1. Material Considerations.
  2. Radius.
  3. Wall Thickness.
  4. Gate Location.
  5. Draft.
  6. Inclusion of Ribs.
  7. Mold Shrinkage.
  8. Special Features.

Is plastic engineering a good career?

If you are technically strong in knowledge about plastics, you are very much wanted in R&D jobs and you are more paid than you think abroad. 6. Easy to study than other engineering streams. If you pursue it from CIPET-Chennai or Ahmedabad then it is a very good course for both girls and boys.

What is the difference between elastic design and plastic design?

Explanation: The main difference between elastic and plastic deign is the assumption of the behavior of the structure. In elastic design we assume that structure will fail if it reaches elastic limit but in plastic analysis we consider that structure will fail when it reaches lower yield point.

How much money does a mechanical designer make?

While ZipRecruiter is seeing annual salaries as high as $92,000 and as low as $31,500, the majority of Mechanical Designer salaries currently range between $51,500 (25th percentile) to $71,000 (75th percentile) with top earners (90th percentile) making $84,000 annually across the United States.

Which is the best software for mechanical design?


  • Mathcad.
  • Finite Element Analysis (FEA) Software.
  • SolidWorks.
  • Unigraphics.
  • CATIA.
  • programming language.
  • ProE.

What is boss thickness?

A typical boss is an open-topped cylinder, essentially a round rib. Standard guidelines suggest that its wall thickness be between 40 and 60 percent of the thickness of the wall from which the boss rises.

What does a plastic engineer do?

Plastics engineers develop and test new plastics, known as polymers, for new applications. Students interested in studying materials engineering should take high school courses in math, such as algebra, trigonometry, and calculus; in science, such as biology, chemistry, and physics; and in computer programming.

Why is plastic part design important for injection molding?

Plastic part design plays a very important role in ensuring injection molded plastic part quality. If the plastic part design is as per guidelines, a relatively better injection molding window can be achieved. Therefore more variation in the injection molding process can be accommodated.

What are the guidelines for plastic part design?

Therefore Boss design in plastic parts should be as per guidelines to ensure boss strength and avoid injection molding defects. Recommended boss wall thickness is 0.6 times of nominal wall thickness of the plastic part. Note: We can increase Boss wall thickness to increase its strength.

How does uniform wall thickness improve plastic part design?

Uniform wall thickness in injection molded parts ensures molten plastic is not forced through varying restrictions during injection molding. Therefore it allows the injection mold cavity to fill more easily. How Uniform Wall Thickness Will Improve Plastic Part Design?

How are plastic products made in mass production?

If these products are made out of plastic, there are numerous ways we can mass produce them: At Jaycon Systems, we have chosen to use injection molding as the main manufacturing process to bring plastic products to life. However, injection molding is not simple.
