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…

One of the trickiest materials to mold with is Nylon. The material itself has great molded in properties, such as strength and when used properly visual aesthetics. Using the material itself, however can sometimes require a strong molding approach to prevent molding variances and defects
This article will address some common problems that occur in nylon molding. It will identify many of the normal molding conditions that are common with this material, as well as provide some insight into processing approach that can help to reduce, and even eliminate scrap events….
This article outlines the value of historical data as it relates to physical conditions outside of the normal process control measurements normally monitored. It will provide three primary examples of what physical data should be recorded, and how to use that information to identify changes occurring within the original molding conditions.
Rare is the occasion that you will find me writing an article in first person. However this article is best presented with analogies and 30 years past experience. Initially I covered 10 scenarios that occur which cause “scientific molding” based companies to fail in their utilization of the principles they attempt to practice. There were many more I could outline, but to prevent readers from sleeping through my soap box episode, I only gave 10 reasons. The article received huge response, and excellent feedback. In revisiting this article, I will revise the first ten and include another five.. bringing the total to 15….
The plastic411 CORE Processor training system is an in-plant training program that first identifies the strengths and weaknesses of your team,, and then develops in-house training at your plant using your presses and equipment!
This is NOT class room training that is quickly lost with very little retention due to the generic content of many programs that often are not providing information that applies to your plant!
- PROCESSING I (includes scientific molding intro)
- Scientific Molding
Plastic411 2 day training programs cost considerably lower than most major training companies.. but content is primarily the same.
The primary difference? The training is developed to be company specific. Very little class time.. on your floor, using your plant’s equipment, materials and processes. 2 day courses that you and I develop together.
The purpose of the training is simple.. to build core skill sets that apply directly to specific company needs and weaknesses. I developed the program based on the common complaint that current platforms have become universal. Much of the information taught isn’t retained because content doesn’t pertain to plant specifics, which makes it difficult to apply in a molder’s own specific environment.
Training Availability: Continental US. PROCESSING I generally starts at $3800, up to 6 attendees. Travel is of course an additional expense. Currently operating the business out of the mid west (Michigan), but also operate out of Florida. 6 month rotation.
