Plastic Injection Articles

This page offers links to articles written on plastic injection processing by Garrett MacKenzie:

    • Plastic Injection Process Adjustments

      This article will outline various process changes a processor has available to him when a process requires change. It will outline specific parameter changes, their potential outcomes.. as well as specific problems to look for. It will also provide insight on how long it takes for specific changes to take effect .

    • Eliminating “Fire Fighting” in Plastic Injection

      “Fighting fires” may be commonplace in many injection molding facilities.. but no company is bound by its terms. By acknowledging the issues at hand, a facility can liberate itself by making strong, committed strides towards resolution. Continuous improvement is not bound by time constraints, but with hard work, commitment and a true analysis of facility failures, any company can plow through even the worst complications and succeed!

    • Laws of Viscosity in Plastic Injection

      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.

    • Plastic Injection Press Shut Down Procedures are Key to Successful Start Ups

      A molder can sometimes dread the tasks associated with a full plant restart.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.

    • Understanding Plastic Injection Material Properties

      This article will outline basic material properties from a processor’s perspective. It will also explain some of the more complex terminology in ways that the average individual can understand.

    • Molding with Nylon: Tips and Tricks

      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.

    • Process Control Requires Proper Mold Heating and Watering

      This article offers 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.

    • Increasing Mold Life While Reducing Repairs

      Tool life is key to a companies bottom line and profitability. With the design and building stages complete, it is time to set the mold in the press and develop a process. This article will not only outline key settings that are paramount to mold life longevity. It will also outline what preventative maintenance steps must be taken to extend the life of the mold.
