Tool Guide: Injection Molder

Note
Something	More Something

The machine is pretty simple... just a few buttons.

Needed Items

1. Adapter that connects the nozzle to your mold... it's blue
2. Plastic beads
3. Mold
4. Gloves
5. Hotplate

Steps

1. Turn on the machine and make sure there is plastic in it.
   1. The switch is on the left side.
   2. The plastic is held on the right. There is a gate, so lift it and fill that area with the beads.
2. Set the heating temperatures for the nozzle ad barrel. These are specified on the front of the machine, and they are entered into the little screens on the left.
3. Check clamp force..... still figuring out how to choose the right amount
4. Heat up your mold's parts and the adapter on the hotplate. Heat them until the mold side is warm to the touch, this isn't an exact science. This prevents the plastic from cooling to fast or clogging parts of the mold.
5. Pl
6. Check to make the table will be at the proper height for injecting. Proper height is the height where when raised, the arm will click and the adaptor connects well with the nozzle.
   1. Table height can be adjusted on the side with a hex key. You can also just support your mold on other pieces of material if the table is too low.
   2. Push the red button on the bottom left to raise the table. The arm should make a clicking noise and the adapter should connect with the nozzle.
7. Adjust the position of the mold so it is aligned with the nozzle.
8. Put the mold on the table, and align the adaptor how with the mold's hole. The wide part of the adaptor is on top
9. Push the red button to raise the table and when it is raised, push the black button on the right to inject the plastic.
   1. Release the black button when the hissing subsides, or you see plastic leaking from the sides.
10. Take the mold off of the table, and pull the part out of it.
11. Clean parts, reheat as needed, and repeat.

Notes and Troubleshooting

• If plastic consistently leaks out the sides of the mold, check your clamp force and if the arm locks.
• If it just wont work and you don't know why, check to make sure the ram is raising all the way in the part where you insert the plastic beads.
• It won't work if the gate on the side is open.
• ABS is easier to mold than Delrin.
• There are other buttons on the front we don't know how to use.
