We are said to be living in an era of Plastics since 1974, as the world consumption of plastics from that year onward exceeded that of steel by volume! From household appliances to airplanes, from tooth brushes to telephones, from Computers to cars, everything seems to be made out of plastics these days. Injection moulded plastic parts offer unbeatable combination of Light Weight Construction, Flexibility, Toughness, Chemical Resistance, Long-term Performance and Cost Effectiveness.

The defects in injection moulding may be caused by poor part design, wrong selection of material, poor injection mould design, poor manufacture of mould, non-optimum process parameters and wrong matching of mould with machine amongst others. Knowledge of ways and means of overcoming these defects is necessary to obtain world class injection mouldings.

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) is organizing a 2 day programme on Defect Analysis & Trouble shooting of Injection moulded components on 22 - 23 June 2023 at Bangalore.

Key Takeaways

After undergoing the programme, the participants will be able to -

  1. Understand root causes & address the defects with suitable remedies
  2. Move towards zero defects in moulding
  3. Become self-certified supplier for OEMs
  4. Implement analytical approach to problem solving of moulding defects.
  5. Understanding the importance of mould / die design during product design.
  6. Importance of process simulation during die design
