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

What is suck back in injection molding

Good morning dosto Suck back , Naam se hi lag rha hai ki koi cheez suck ho rhi hai yani kheechi ja rhi hai . Suck back ka matlab hua peeche ki taraf kheechna . Actually jab plastic melt material mold me inject ho jata hai aur injection ke baad holding complete ho jati hai tab part cooling zone me jata hai aur isi waqt refilling bhi sath sath hoti rhti hai refilling poori hone k baad screw straight direction me back hota hai utne mm jitna set kiya jata hai. Alag alag material k liye alag alag value me set krte hai suck back Suck back dene se drooling ki problem ko solve kiya jata hai aur sath hi sath silver bhi troubleshoot hota hai .suck back dene se material me threading generate nhi hoti hai nozzle se

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

What is l/d ratio

L/d ratio👉 Yah screw ki flight length aur outside diameter Ka anupat Hota Hai jyadatar yah anupat 20:1 hota hai aur ya 18:1 se 24 * 1 Tak hota hai dharmon set material Mein yah anupat 12:1 se 16 is Tu Van tak rahata hai Jyada Se Jyada share hit generate Hoti Hai plastic Mein Bina Jale Hue Jitna Jyada mixing hoti hai utna hi h*** genus melt hota hai Jitna Jyada residence time hota hai plastic ka barrel mein aur LCM Jyada hoga to kam cycle time mein Bade shots nikal Lete Hain. To yah To Kuchh definition Thi doston ab main aapko Aasan bhasha mein samjhata hun ki l y Di ratio Hota kya hai dekhiae jo screw ki lambai hoti hai usko Ham bolate Hain flight length theek Hai Doston Kyunki yah flight Jahan se start hoti hai aur jahan tak flight ka end hota hai rinklanjar wale part Ko Chhod Karke is group mein vah lambai kahlati hai flight length aur jo nominal diameter hota hai is group ka usko Ham outside Tak napte Hain usko Ham bolate Hain out side diameter ine donon ka hi jo ratio Hota Hai vah...
