Nylon Molding: Tips and Tricks

By Garrett MacKenzie- Plastic411 Editor

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….

Scientific Molding Work Shop: Dalton, GA March 24-25, 2018

This page outlines the upcoming Scientific Molding workshop being held March 24-25, 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…

15 Reasons Molders Fail at Scientific Molding

By Garrett MacKenzie

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….

CORE Plastic Injection Processor Training

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.

FREE Scientific Molding Webinar: Plastics Today

 

FREE SCIENTIFIC MOLDING WEBINAR

February 13     11:00 AM PST

Plastic injection processing has experienced massive change in the last 20 years. The days of molding by time and pressure have given way to molding by position, peak pressure and process repeatibility, aka scientific molding.

I am hosting this Plastics Today webinar and will provide instruction on key scientific molding principles.

Essential topics include:  process development, recording, monitoring and control; standardization; design optimization experiments; and process optimization.

Molding managers, process engineers, quality engineers, process technicians and anyone who needs an understanding of scientific molding and lean manufacturing concepts will benefit from this webinar.

 

Attend this webinar and learn:

 

  • What is needed during the process development stage
  • How to capture all scientific data specific to a process, including melt and mold temperature and turbulent flow
  • How to avoid situations that adversely affect process standardization (including an overview of tools that improve and verify process consistency)
  • Techniques that improve cycle times without jeopardizing process consistency and scrap rates
  • The nuances of fill time, gate seal, back pressure, pressure drop, cavity balance, melt and mold temperature, cavity pressure, viscosity and more

Eliminating the “Fire Fight” in Plastic Injection

Plastics production rides a fine line when the goal of low scrap, high yields and sustainable, repeatable systems are being developed. Without the proper approach, the system can  quickly fall into one of two categories: tribulation.. or turmoil. Quite often you will hear old school molders describing their battle for a robust processing system as “fire fighting” in the world of plastic injection molding. In real terms, “fighting fires” on the production floor is a sign of system failure. True molding standards don’t require constant coddling, adjusting, sorting, etc. It is real easy to fall into the trap of applying “Band-Aids” to molding situations when the proper approach should have been……

Top 10 Reasons Molders Fail at Scientific Molding

TOP 10 REASONS COMPANIES FAIL AT SCIENTIFIC MOLDING

Rare is the occasion that you will find me writing an article in first person. I have always just felt that the best way to include my molding peers in the depth of the topics I cover is to put them in the driver’s seat. However this article is best presented with analogies and 30 years past experience. As such, I will be covering 10 scenarios that occur which cause “scientific molding” based companies to fail in their utilization of the principles they attempt to practice. Trust me.. there are many more I could outline, but to prevent readers from sleeping through my soap box episode, I will limit my scope to 10…..

Effective Machine Shutdowns are Key to Successful Start Ups

By Garrett MacKenzie

press floor

The weekend comes to an end and the time comes to bring the molding floor back online for the beginning of a new work week. A molder can sometimes dread the tasks associated with a full plant restart. There are many potential failures that can occur as a plant is returned to a production state. Despite these risks, much of the headache can be avoided simply through proper shutdown and start up procedures. The following article addresses many key components that often lead to poor restarts. It also provides insight into some of the methods that can be implemented to not only reduce system breakdowns, but also can offer smoother start-ups with fewer problems…
