### How to Make a Bookmark

## Steps
|
|
### Step 1: CNC your mould
|
|
|
|
### Mould-Making Instructions
|
|
|
|
Download the files provided and either CNC-mill them or send them to a mould maker.
|
|
|
|
Use an aluminum plate with a thickness of 0.39 inches (10 mm). Each side of the finished mould should measure 3.94 x 5.91 inches (10 x 15 cm).

|
### Step 2: Alternative: Buy The mould
|
|
|
|
If you cannot make the mold yourself, it can be purchased at the link provided below.

|
|
|
|
### Step 3: Time to inject
|
|
|
|
Your mold should appear as shown when ready.
|
|
|
|
Given the thin object, preheat the mold to approximately 176°F (80°C) to facilitate easier injection.

|
### Step 4: Inject the parts
|
|
|
|
Time to inject. The plastic should be evenly melted to spread smoothly into the mold (mould). It may flow out of the nozzle due to gravity, so use a valve to control the release, opening it just before injecting. Act quickly and maintain pressure for a few seconds to prevent sink marks as the plastic cools under pressure.
|
|
|
|
After injection, open the mold (mould) promptly. Delays can make it more difficult to release the object due to plastic shrinkage.
