Automation/Robotics

Injection Molding Automation

Polyfab strives to automate all injection molding projects to minimize hands on involvement, resulting in improved consistency, repeatability, product quality and ultimately the best value for our customers.

This Is Facilitated By:

  • Early evaluation of your product requirements and the opportunities for process improvements.
  • Experienced automation engineers on staff to design and manufacture optimum interfaces and equipment for your product needs.
  • Hands on knowledge of a wide variety of automated secondary operations including trimming, assembly, and flexing living hinges before packaging.

Scientific Approach – Problem Solving

The molding process is developed using a systematic, data driven approach. Those conditions that prevent necessary process control are first identified and corrected. Then, a robust, repeatable process can be established and defined by meaningful plastic conditions, independent of machine settings.

Polyfab is staffed with a Master Molder Certified Process Technician on every shift. Communication between technicians takes place using common terminology regarding specific process inputs and outputs. Because of this, problem solving is a systematic procedure structured around defining the root cause, with actions taken based on knowledge of the process.

Some of the tools Polyfab uses to drive process control and improvement through meaningful data include:

  • Kistler “CoMo” cavity pressure sensing
  • RJG “eDart” cavity pressure sensing
  • Our Great Employees
