TECHNOLOGY OF INJECTION MOLDING – LEVEL 2
Goals of this Course:
- Learn to process from the plastic’s point of view
- Understand what scientific molding really means
- Reduce scrap rates, downtime and cycle times
Paulson’s fully interactive training program explains the relationship between machine controls, plastic behavior and molded part properties in full motion video, text, audio and graphic animation.
Course Description: Optimize the Process. Moving up from Level 1, in Level 2, learners will dive deeper into the scientific approach to injection molding and the importance of understanding the effects of each machine control on the four primary injection molding variables—heat, pressure, flow and cooling, and how these variables affect part properties. This molding course assumes the student understands the effects of each machine control on the molding machine and on the plastic. In this course, we utilize SkillBuilder™, our hands-on molding machine simulator, for the first 3 lessons.
In SkillBuilder™, molding machine setups are pre-set on the control screen with various problems. The molder must adjust the machine controls and cycle the machine to solve the part defects that occur. It is highly recommended that anyone taking this course have processing molding experience on machines or have completed Paulson’s The Technology of Injection Molding – Level 1 or the Paulson Plastics Academy ProMolder™ 1 seminar.
To really strengthen your knowledge we highly recommend adding on our proprietary and revolutionary injection molding simulator SimTech™. Immediately apply your new skills with our pre-set virtual molding lessons, users will have the opportunity to solve Molding Challenges with Paulson’s advanced molding machine simulator SimTech™ (exclusive to Paulson). Students will be presented with a molding problem which they will need to solve and achieve the best cycle time. Who will be the best molder in your plant?
Recommended For: Intermediate to advanced personnel
Length: 3 Lessons – 8-10 Hours of Training
Language: English, Spanish
Lessons Included:
Lesson 1 – Pre-start, Safety, and Setup for a Mold Run
This lesson teaches optimizing pre-start, safety and process control set up procedures involved in improving injection molding machine operations. A review of the injection molding cycle from the “plastic’s point of view” is done, as is the indirect relationship of the machine controls to the molded part properties. The importance of startup checks on machine protection and personnel safety is emphasized. Teaches the effects of the different types of plastic on the molding process, and setting the machine controls at startup. (Includes 2 SkillBuilder™ lessons)
Lesson 2 – Mastering Machine Control Settings
This lesson moves on to additional machine controls and their effects on both the molded parts and overall cycle time. Students will learn how melt temperature is adjusted using barrel zone settings, screw RPM and back pressure. Next, students will learn how to measure the melt temperature and the importance of setting a proper cushion size, melt decompression, screw back distance and screw delay when necessary. (Includes 1 SkillBuilder™ lesson)
Lesson 3 – How to Achieve Maximum Productivity
In this lesson, the focus is on maximizing productivity once a stable process has been achieved. Student will also continue to learn how to adjust machine controls to solve molding problems. Adjusting fill rate to control burn marks, jetting and flash. Velocity-to-pressure transfer (VPT) to eliminate cavity pressure variations; cushion size to minimize melt temperature variations; melt decompression to minimize screw valve wear and drool. Additional controls having specific purposes and effects on the part properties including pack/hold pressures, mold closed time, ramping, and more. (Includes 4 SkillBuilder™ lessons)
