Molding With Plastic Resin

Resin injection molding is the manufacturing process of molding raw plastic pellet into usable parts.   Thermoplastic resin is the most common type of plastic used in the polymer molding process.  The resin, or plastic pellets, is used by injection molders to make parts for a wide variety of industries.

 

Custom injection molding is the process used by custom molders to make parts that are designed by others, typically engineers in the Automotive, Aerospace, Consumer Electronics, or Medical field.  Injection molding is also used for the Furniture, Construction, and Toy industries, although precision molding is required for the former mentioned industries requiring a high level of quality with tight tolerances.

 

Each resin has a melt temperature when it becomes pliable, which allows it to flow through an injection molding press, into a barrel and screw, where it is injected with pressure into a steel mold forming the desired parts.  After forming, the mold ejects the parts and closes again to prepare for another cycle.

 

Characteristics of Thermoplastic Resins

 

Thermoplastic resins have a unique ability to be strong and durable, yet also lightweight which makes is a desirable material for several functional parts. They can be reinforced with glass filled polymers, or they can have a rubber like appearance, and several variations in between.  They can be made into virtually any color, size or shape.  This flexibility is the main reason that plastic resins are the material of choice for supplying various industries with necessary functional parts.  Some examples:

 

  • Polycarbonate
  • Polyethylene (low or high density)
  • Polyethylene Terephthalate (PET)
  • Polypropylene (Acetal)
  • Polyphenylene Ether (PPE)

 

The experienced molder has all procedures in place to provide full traceability throughout the resin injection molding process up to and including shipment of quality parts that meet or exceed customer specifications, along with proper documentation.  Contact Michiana Global Mold today to see how we can help you with your injection molding needs.
