You can only imagine how exciting it was for industrial engineers and researchers when they were conducting research to understand the strategy and tools behind Toyota’s meteoric growth.
All the studies showed that Toyota was faster, with less costs and inventory, and delivering a higher quality compared to the American and European automakers. And it wasn’t by a small amount; Toyota used a small fraction of the inventory yet built cars on time every day with high quality…..
I just wanted to let members know that the spam issue is fixed. Initially, I was having to delete +100 members for spamming per day.
After some research, and about 13 hours of making changes and developing block lists, the site is free from nearly all the spam! If you come across anyone that is not using the site as a plastic injection-based platform, please contact me at: email@example.com. Thanks!
A lesson on shear induced melt variations ends some confusion regarding balancing runner systems
for multi-cavity molds.
The Beaumont Effect is recognized as the source of mold filling imbalances and product variations in molds
with four or more cavities. The worst failures caused by the phenomena can be most easily (visually) recognized
in molds with 8 or more cavities. However, shear induced melt variations impact every injection molded
part, with a greater influence than most realize….
It is curious that in a world that relies increasingly on documentation, the attention to the details of polymer composition receive so little attention. Companies will fill volumes with procedures for various aspects of their manufacturing processes. However, no serious consideration is given to verifying the composition of the raw materials that are used to produce the various molded parts until there is a problem. Instead, there is a tendency simply to refer back to whatever published information is available from the material supplier….
Viscosity is a very large category that has huge effects on standardizing molding processes. It is also one of the most important factors in a molder’s arsenal of making process changes. This article will first explain viscosity, and then delve into different situations where viscosity may help or be hurting a processors goal of zero scrap and high output…..
When trying to establish process control in plastic injection, watering the tool is a key variable that is often overlooked. Water set-up and design are every bit as important as establishing and recording a repeatable process. The steps taken when watering a mold are key to a processor’s goal of consistency. If during the design and development stage, watering is put on the back burner as an “unimportant” variable, the potential for lost process control is huge.
Below are some insights into the most important facets of cooling or heating your mold, as well as what recordable data are important in the initial stages of process engineering…
I once had a plant manager who had the perfect analogy for the use of visual management, by implementing an engineered shop floor layout with clear and concise instructions at each employee’s workstation. The question he asked our team was this: “Why is it that when you look at a shampoo bottle, there are directions to ‘Rinse, Lather and Repeat’?” His answer was simple, yet thought-provoking. ”Someone at some point stood there with the bottle, trying to figure out what to do with it.”
Simply put, the better you are able to remove complexity from the shop floor and provide concrete visual and descriptive aids, the more control you will have over your plant’s overall performance…..
In lean manufacturing, changeover times are a vital component of shop performance. Minimal down time assures that multiple changeovers have little effect on a plant’s available machine time available. After all, less down time in the production equation offers more opportunities to take on more work and increase company profits. This article outlines specific approaches towards color changes that will support the potential of completing color changeovers in 3 to 7 minutes. This may seem like an impossible task to some, but with the proper planning, methods and equipment, it is an attainable and repeatable goal…..
