Injection Mold Making Technology

Injection molding is the mass producing of plastic parts with a steel mold, an injection mold, designed with cavities to mold the desired part.  Injection molding uses thermoplastic resins, also called polymers, typically in a raw pellet form, that melt and flow into the cavities in the mold, forming the part, then it is ejected once it hardens.  The time that it takes for the mold to close, plastic to flow into the mold, the polymer to set and eject upon mold opening is called the cycle time.  Injection molders are always looking for ways to increase the cycle time, as time is money and when you can mold a part faster, you can mold more per hour, per day and per week.  

A skilled injections mold maker will have the knowledge to design the mold with the most appropriate attributes to reap the best cycle time while still delivering the desired part to the customer specification.  Michiana Global Mold is accustomed to constructing complex, precision injection molds within +/- .001”, which is about the thickness of a human hair.  

Injection Mold Making Equipment

Injection mold makers are well familiar with the precision equipment used to carve out steel cavities, forming a perfect plastic part.   Computer aided design, and computer aided manufacturing (CAD/CAM) equipment is a key tool for designing a perfect tool.  The designers at Michiana Global Mold use Unigraphics CAD/CAM software to design the mold fit for producing a desired part.  This alerts the mold maker and the injection molder to any critical areas such as thin walls or a critical dimensional tolerance that must be met, prior to cutting steel.  

Milling machines, conventional EDM and wire EDM machines are a necessary tool, along with high speed CNC machines, drill presses and grinders.   Michiana Global mold, located in Mishawaka, Indiana with an offshore mold making facility in China, utilizes all of these mold making equipment tools, and more.  We have over 50 years of experience constructing complex tooling for demanding industries such as the Automotive industry where 0 ppm (parts per million) defects is the norm.  The key to a quality plastic injection molded part, is a quality injection mold.
