This article will explain the pros, cons and procedures of regrind processing. There is of course a need to reprocess lost materials to reduce the costs of materials lost to the production of scrap. But there also needs to be an understanding that scrap prevention is the first and most profitable response….
How 2K Tool in Grand Rapids, Michigan is helping to protect citizens, while helping save medical masks for health care workers…
These are trying times for many of us in manufacturing. With the Corona virus still rampant, many plants are being held under siege to protect their workers as directed by government stay-at-home directives. Many companies are suffering financially, while its employees are forced to stay home.
Kevin Smith recently had an idea as he sat in his living room watching the news. A request had been made for tool makers to develop tooling for facemasks, and Kevin seen it as an opportunity for his business to help. His own business had seen a drop in sales due to many of his customers being automotive suppliers. He finds himself blessed to have customers that are considered, “essentials”. His business is still in operation, while many operations are closed due to Michigan’s current “stay-at-home” Executive order.

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…
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.
Process adjustments result in a multitude of possible results, both good or bad. Process adjustment in regards to machine response can be compared to older style radios with knobs designed for both broad and fine tuning. The larger knob can be adjusted for aggressively adjusting frequencies to get to the station you want. The smaller knob allows for fine tuning of a particular station.
This article addresses various process changes a processor has available when making process adjustments to new or poorly performing processes . It will outline specific parameter changes, their potential outcomes.. as well as specific problems to look for after adjustments have been made. It also provides insight on how long it takes for specific changes to take effect ….

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 robust process. RJG and John Bozzelli were major pioneers in the development of decoupled and scientific molding as the procedures were developed and given structure. Plastic injection as an “art” gave way to plastics processing as a science of repeatable, standardized processes.
