Machine description
Machine design:
Motor Injection Machine
Machine size:
Heigth: 195CM; Wide: 50CM; Large: 50CM
Machine cost:
In Colombia, Bill Of Material = COP$4,700,000
What makes your machine different to others:
This machine has a motor that will apply the pressure (versus a hand powered lever on older versions). It can be considered an upgrade to Precious Plastic Basic Injection Machine, available on the academy.
Compatible with:
This machine is suitable for injection moulds.
Type of plastic:
PP, HDPE, LDPE, PS
2
Tools needed
To build this machine, you will need:
-- Turning (machining on a lathe)
-- Milling (machining on a mill)
-- General metalworking (cutting, drilling)
-- Welding
-- Advanced assembly work (require specific tools, measurement instruments and tolerances knowledge to align and assemble)
-- General electrical work (wiring safety switch, temperature controllers…)
-- Motor electrical work (wiring motor, contactor, overload protection…)

Inject!
How to use the machine
1. Turn on the machine and fill the barrel with plastic.
2. For the first injection, wait 25 minutes since the machine was turned on and filled.
3. Place the mould over the jack surface and press it against the nozzle tightly.
4. Turn on the motor to move down the piston, pushing the molten plastic inside the mold until the belt starts slipping in the pulley.
5. Turn off the motor and wait around 5 seconds maintaining the piston pressure.
6. Then turn the motor backwards to move the piston up
7. For continuous injections refill the barrel before removing the mold from the nozzle
8. Remove the mold by lowering the jack
9. Open the mold and take out the injected part
10. Close the mold and repeat the process from step 3
Recommendations
For this machine, you will need molds that have a connical nozzle connection or create an adapter to fit with you mold nozzle. This machine can create a lot of pressure so you will be able to inject products with very thin walls.
