MAKING SIMPLE ELECTRIC OVEN. See description for safety. 

If you buy an electric oven specifically for acrylic, the price is usually relatively high with high power too.
Making this oven is intended for DIYers to make it easier to heat acrylic.
CAUTION: Ovens have low safety, therefore you should also prepare safety equipment such as:
1. APAR (Light Fire Extinguisher).
2. Wrap all exposed wires that are exposed to heat with asbestos hose so that they do not melt or come into contact with the oven body.
Remember: When the cable is exposed to heat, it will expand and can bend and touch the oven body.
3. Use a maximum of 3/4 of the power available at home.
Example: For a house with a maximum power of 10 Ampere or 2200 watts, it is recommended that the total heating element power be a maximum of 1500 watts.
4. Use a special electrical route with a safety circuit breaker (MCB, Miniature Circuit Breaker).
5. Don't leave the oven on, always double check when finished.
