Wyndham Grand Bangsar Kuala Lumpur Hotel (Physical)

  (SBL Khas / HRD Corp Claimable Course)

Date : 23 Apr 2025 (Wed) |  9am – 5pm                 By Selvaraj

24 Apr 2025 (Thu)  |  9am – 5pm                 .    .  

        

INTRODUCTION:

Scientific Injection Molding is typically used in the production of complex parts and components where small variations in molding variables can severely impact the process or finished product. Therefore, the goal of Scientific Injection Molding is twofold:

1. Develop a process that produces repeatable results with minimal variation.

2. Optimize dimensional or mechanical characteristics of a molded part.

When developing a molding process using Scientific Injection Molding, key inputs such as time (fill, pack/hold, etc.), temperature (melt, barrel, etc.), and pressure (hydraulic, injection melt, cavity, etc.) are meticulously monitored, adjusted, and controlled, to ensure that process robustness is achieved, and a good part is consistently produced. A process can be robust or on the other hand must be changed frequently. A robust process ensures repeatability and a wide processing window for better quality & cost. 

 

COURSE OBJECTIVES:

1. Material properties that affect processing

2. The importance of drying

3. Explains specific rules for controlling the plastic during processing

4. Injection molding machine selection

5. Provides thorough overview of injection molding and troubleshooting techniques.

6. Exercise greater control over the molding process

7. Reduce rejects and scrap

8. Improve part quality

9. Increase productivity

10. Robust parameter optimization

 

INTENDED AUDIENCE:

This workshop has been designed for all Managers, Section Heads, Engineers and Senior Technicians who are involved in the process of Plastic Injection Molding and want to make their workplace more productive & optimized. Following groups of people will benefit from this training:

1. Tool makers

2. Manufacturing engineers

3. Production engineers

4. Any technical personnel involved with plastic injection moulded parts

 

METHODOLOGY:

1. Participants will inform the organizer their top 6 issues to be discussed during the Troubleshooting section.

2. Interactive and action based with personal examples.

3. Participants are strongly encouraged to prepare their statistical software of choice for DOE simulation.

 

PREREQUISITE:

Participants are expected to have a basic understanding in Plastic Injection Moulding with a minimum of 2 years’ experience.
