Plastics processors are responsible for making process corrections when defects affect their scrap rate. One of the most common defects in plastic injection is splay. Splay adjustments can be a simple fix, or several hours of babysitting a press and head scratching. This article will help to identify various forms of splay, as well as common (and less common) causes. It will also provide various solutions for removing splay from your process….
Plastic Injection Troubleshooting:
Using Scientific Molding Approach When Validated Processes Fail
Many companies apply scientific principles to their set up and validation of processes. After all, this methodology has proven its worth as a successful approach in process development. However, it is important to note that SM goes beyond set up. The true test of processors is how they evaluate change in validated processes that have already been proven. This article will define criteria that identify root causes for change and provide information and approaches to evaluate and correct changes that occur…
Upcoming Webinar: September 11, 2018 2PM PST
Scientific Molding Approach in Plastic Injection
Process Troubleshooting using Scientific Molding Principles
This webinar will provide attendees with specific Scientific Molding variables that can identify changes within an existing molding process, as well as provide insight into specific approaches that can be used to bring a validated process back into normal process parameters.
Who Should Attend: Molding Managers, Process Engineers, Process Technicians, anyone who needs an understanding of process validation and Scientific Molding Procedures.
When you attend this webinar, you will:
- 1. Learn the significance of developing a record of historical data, and how to use that data to identify changes in a validated process
• 2. Be taught which key recordables best define and evaluate key molding measurables, and how they interact with process adjustments
• 3. Receive specific examples of changes that often occur in normal processing scenarios, and be given specific solutions to remove the problem.
• 4. Learn how to categorize a change by using the 5 M’s method: Man, Mold, Machinery, Material and Maintenance to identify the key approach for correcting a change in process.
• 5. Learn tools that will combine strong process development approach with key measurable recording to assure fast resolution to process variations that occur after a process has been validated.
This page outlines the upcoming Scientific Molding workshop being held October 27-28, 2018 at CH3 Solutions (event sponsor) in Dalton, GA . The event is 2 full days, from 8AM to 4PM.
This is NOT class room training! Both days of training take place directly on the machine:
- Process Development: Participants will be trained how to establish a new process using decoupled molding technique
- Process Recording: Attendees will be shown how to record all scientific data that is specific to a process. This includes melt and mold temperature data, as well as turbulent flow-specific data
- Process Monitoring & Control- Instruction will be given regarding monitoring and process control. Participants will learn what process control limits are flexible, and which need to be rigid to maintain the rigidity of the process…
