Plastic Injection Molder

Plastic Injection Molder Information

The Morgan-Press G-100T Injection Molding machine is a small production plastic injection machine. It is equipped with air driven pistons providing the power to clamp molds and inject thermoplastic material into molds. It works with an array of plastic pellets.
  • MakerSpace Orientation and the Plastic Injection Molder Training are required to use this machine.
    • Presently, the machine training can be requested via email to tandon-makerspace@nyu.edu.
    • Visit our Training Page to learn about our MakerSpace Orientation, other machines, and services available at the MakerSpace.
  • This machine requires a metal mold to produce parts.
  • Designing and machining a mold for injection molding is the most difficult part of the process.
  • You must source a suitable mold, have one made, or make one yourself.
  • Molds can be made out of aluminum or steel.
  • See "Mold Accessory" under the Print Materials and Pricing section for 3D printed mold option.
  • No software is required to run the machine.
  • For designing a mold, you can use a solid modeling program such as SolidWorks, Autodesk Inventor, or Fusion 360.
  • SolidWorks and Inventor have tools for moldflow simulation, though this is not always required for prototype runs.
  • 6 cu. in. (4 oz.) max. single shot (total part volume)
  • 20 ton max. clamping force
  • 12,000 psi max. injection pressure
  • 0-800°F (0-430°C) temperature control range
  • Mold plan size 8″ x 11″ (maximum)
  • Molds shorter than 5" require a riser block
Materials
  • The machine is marked with temperature settings for the following materials: ABS, Acetal, Nylon, PPO, Polycarbonate, Polyethylene, Polypropylene, Polysulfone, Polystyrene, Urethane, Vinyl.
  • Ensure the lab ventilation is active to remove potential plastic fumes.
  • Materials such as ABS, Polycarbonate, Vinyl, and PVC must be purged from the barrel before shutting down to avoid residue or corrosion of the barrel. Flush with an inert plastic, such as polyethylene.
  • Some plastics such as acetal and nylon require the nozzle to be changed to the anti-drool nozzle. Seek assistance for this procedure.
  • The regular nozzle is size B, with an orifice of 3/16".
  Mold Accessories
  • To facilitate short molds, the MakerSpace has two 4"x5"x2" (nominal) riser blocks that allow it to be clamped.
  • The MakerSpace also has an aluminum housing designed to hold a mold printed or cast out of heat-resistant plastic (such as Formlabs High Temp Resin for Form 2).
  • This can also be used as a "purging mold" when empty.
