Colour variation defect in injection molding

 Hi friends many times we face problems in plastic parts regarding colour variation . Now the question arises why is this happen .why the same material and same amount produces equal amount of colour it is generally happens due to  masterbatch that we mix in material .first a fall we have to use same grade and same company master batch if possible.and mix it very well with material  in proper amount . #injectionmolding #whatissuckback #drooling #plasticprofessional #polymer #processengineer #production #engineer Actually using masterbatch is very cheaper than using the same colour material which is about to little costly  hence

Types of plastic

Plastic 2 prakar ke hote hai 1 thermoplastic 2 thermosetting plastic Wo plastic jo ek baar heat dene k baad   soft ho jate hai aur easily doosrey article me convert ho jate hai .isme na unki physical property change hoti hai n chemical property change hoti bus sirf physical look change ho jata hai Jabki thermosetting plastic me  agar ek baar kisi article ko heat kiya to fir se wo dobara nhi change nhi hoga aur material degrade ho jaega aur dirty si smell aane lagti hai for example aap cooker k utensil hi lelo .isliye thermoplastics achche hote hai kyuki wo recyclable hote hai . Unse koi bahut jyada environment ka khatra bhi nhi hai . #injection molding #plastic #indiaplast #ezyplast #whatisplastic #typesofplastic #plastasia #polymer

How to set barrel temperature

 First of all recall the  melting point of the material that you are going to use . Then  set the feed temperature of barrel .then  set the  feed zone  temperure . After that compression zone temperature and then metric zone  temperature and while setting the temperature we should understand the behavior of environment.  If the part wall is thick temperature should be little higher but not as much to generate burn or flash .  There sould be a difference of 5 ~10 degree celcius temperature between zones
