When it comes to medical molding, cleanliness is paramount. At JunoPacific, we audit all our clean room manufacturing environments quarterly to insure we remain within the ISO designation for particulate count. JunoPacific works harder to insure a clean environment for medical device manufacturing by using all electric presses and transporting the resin to the barrel utilizing a vacuum system, keeping all hoppers and driers outside of the injection molding manufacturing area. Additionally, we use electronic heater cartridges to achieve full crystallization with higher heat materials.

Quantitative Production Tracking

Medical Plastic Injection Molding -- Numbers you can count on

By maintaining meticulous medical device manufacturing history records, JunoPacific can provide zero-defect manufacturing.

  1. New plastic injection molding tools are subject to a rigorous processing window study. Once process parameters have been established, they’re programed into the machine controller so the same process can be used every time. This decoupled injenction molding approach also allows us to switch machines but use the same parameters within cavities.
  2. Full first article inspection reports are generated on each new injection mold using our state of the art clean room equipment.
  3. Part-critical dimensions are checked frequently to track and maintain our CpK values.
  4. Training records are maintained for each of our operators.
  5. First and last retains are kept for each run.

Kanban and Just-in-time Delivery

Keeping clients' medical device manufacturing product lines running smoothly

Upon request, JunoPacific can implement Kanban stocking for just-in-time (JIT) delivery. Implemented with an extremely high success rate, JunoPacific helps clients reduce their inventory to run lean.

Instead of forecasting demand, and pushing inventory to meet that demand, JunoPacific keeps inventory for you in-stock per a kanban card you can pull from as needed.
