New injection press concept/machine to eliminate areas where the mixture is trapped (segregation) and facilitate cleaning and eliminate contamination in the valve

Challenge in metal injection molding machines

  • The injection molding machine market size is projected to reach 105,654 units by 2023, registering a CAGR of 2.26% between 2018 and 2023 (MarketsandMarketsTM)
  • The metal injection molding market size was valued at USD 2.4 Billion in 2017 and is poised to reach USD 3.7 Billion by 2022 (MarketsandMarketsTM)
  • The market growth is attributed to the increasing demand for injection molded parts from automotive, medical, packaging and consumer goods industries
  • Low pressure powder metal injection (LPIM) machines with reduced tooling costs while permitting increased part shape complexity.
  • But uses lower viscosity binder, therefore increasing the potential for powder segregation, and creating porosity in the final molded part.
  • Current LPIM machines have multiple dead spots favoring powder segregation: conduits, injection canal, and injection valve cavity

New design of low-pressure powder metal injection machine

  • Novel design using a sliding table concept to eliminate the conventional valve, injection canal, and conduits
  • Elimination of metal powder segregation during machine pauses
  • Demonstration prototype available
  • Technology developed by Prof. Vincent Demers, Simon Lamarre, and Prof. Jean-François Chatelain (Department of Mechanical Engineering) at École de Technologie Supérieure (ETS)

Competitive advantages 

  • Powder metal segregation eliminated
  • High and consistent finished product quality due to elimination of porosities
  • Lower production costs due to low-pressure injection
  • Higher product design complexity

Market applications 

  • Medical devices
  • Aerospace complex parts
  • Prototyping of parts

Business opportunity

  • Technology available for licensing
  • Potential co-development of new and improved LPIM machine
  • PCT CA2017,050526
  • US patent application 16,097,328
