How to Use Resin to Make Your Own Plastic Stuff

Intro: How to Use Resin to Make Your Own Plastic Stuff

Hi My friends 
Actually i am an electronics designer but since childhood i was interest in both electronics and chemical and i wanna explain about one of my cool test in chemical to using this way as your needs 

first , as you know if you wanna order a plastic melt for your testing design , it's not very economical because most of you are a hobbyist and don't wanna expend lot of money and at leat you must expend 500-600$ to order a plastic melt 
but here i wanna introduce a very helpful and useful way to making your own plastic stuff's 

This way is so so cheap and high quality (mostly depending on your skill) way to making lot of plastic thing's 

So we are go to learn this cool way 

Note: in this session we will learn how to make a liquid resin as plastic and you must make your melt as your needs 

Dangers :
ALL of the material are chemical and please in all stages use safety eye gloss and gloves 
please do not change the amount of the mixed material 
please test this in balcony (with a fresh air)

STEP 1: Essential Stuff's

from lest to right :
1: Resin 
this liquid is one of derivatives of oil and is so so cheap , here is about 2$ per liter :) 
note: we have several kind of resin such as epoxy etc. but as far as i know most of resin are good for our plan 

2:Color 
use special color for resin that be mixable with resin 

3:Final drier , in last stage we mix this chemical liquid with our mixture to make hard our liquid and change liquid to solid 
Note: actually this liquid in kind on acid and the color of this liquid is invisible 

4:First drier or Cobalt : this liquid must mix before final drier 

STEP 2: Pour Resin in a Box

i use a recyclable dish to make our mixture due to resin will make dirty your dish after drying 

for the first test use only 100-200C 

STEP 3: Pour Color in Resin

pour your color in resin 
Note: resin without adding color is primary colors (a little like yellow)

STEP 4: Mix Color in Resin

you have to quite mix resin in all stage very strongly and does not contain any Impurities
Note: please Mix color in resin with a plastic recyclable knife 

STEP 5: Add First Drier

after adding first drier or acid into resin if you mixed very good , you must show a violet mixture
Note: with each 1000CC resin you must contain 100CC first drier 
well , after this stage you have a violet mixture you can store this liquid for about 1 month and after this time will be not usable 

STEP 6: Adding Final Drier (cobalt)

This is the final stage to make a hard plastic and it's just enough to add cobalt to the mixture to make hard that 
well i prepare other empty plastic box to test out plastic  (it's like a plastic melt)
also you must mix 1000CC resin with 200CC cobalt 
you can mix cobalt with mixture before or pour cobalt in empty box and then  pour mixture in the melt 

STEP 7: After Drying

you can watch what we made by resin 

STEP 8: One Sample With Resin

This is a clamp that i made it with resin and right now i use this to assemble electronics boards 
It were so useful in electronics boards

با سلام

من مدت زیادی هست که از این سایت و مطالب و ایده های بسیار خوبی که دارد استفاده میکنم ( مخصوصا در الکترونیک ) ولی اولین باری هست که دیدم یک ایرانی مطلب گذاشته و بسیار خوشحال شدم

امیدوارم که همواره موفق باشید

ممنون از راهنمايي. فكر كنم سوال دوستمون اين بود كه آيا محلول بعد از سفت شدن تغيير حجم ميده؟

[armstk180]

بله , وقتی رزین رو درست میکنین تغییر حجم میده و حجمش موقع خشک شدن زیاد میشه

درود بر ایران

Hi Rimar
It's good news
Thank you for your point , i have to say we call drier as hardener too

if you reduce driers (or hardener) your mixture will dry in longer time and also if you increase hardeners your mixture naturally will dry sooner
Don't remember that you must not add much drier in resin due to resin will get more Brittle

let me know if you have any question

This instructable is very useful for me, thanks for sharing.

As 40 years ago I tried to make a magnifying glass with liquid resin, and left something like a magnifying glass. Surely the liquids used have changed since then, I did not use that first hardener.

I want to ask if the resin shrinks as it hardens.
