Doston short moulding ya fir short shot kya hota hai Iske bare Mein Kuchh baat karte hain.
Jab mold mein plastic melt material ko barrel se tab vah mold ki cavity ke hisab se material ko set Kiya jata hai ki jitne material ko inject Karana hota hai vah part ke shot weight ke hisab se hi inject kara Dete Hain .
doston barrel Mein Jitna material Hota Hai jo ki Jyada Se Jyada bade se bade mold Mein inject karaya Ja sakta hai usko shot capacity bolte Hain aur Jitna material Ham inject Karate Hain usko Ham short size bolate Hain per Jo material Ka weight Hota Hai Jitna Ham inject Karate Hain mold mein kisi cavity ko bharne ke liye Jo impression hota hai Core aur cavity ke bich mein jo ki batata hai ki kitna weight hai impression ka usse yah decide hota hai aur cavity ke bich Jo material Hai vah Kitne shot size ka Hai Kitne gram Ka Hai Isko gram Mein major Karte Hain vaise to short size Jo Hota Hai Chhote mold Mein kam rahata hai aur Bade mold mein jyada rahata hai depend karta hai ki part Kitna deep Hai Kitna lamba hai aur Kitna breadth mein hai.
To doston,
short shot kya hota hai short shot Ek defect hota hai Jaise man Lijiye ki Hamen 20 gram ka product banana hai To Ham 20 gram material hi inject karaenge mold Mein per use 20 gram ko Ham machine aur mold ke hisab se mm Mein convert Karke inject karaenge aur jab material inject kara Dete Hain To mold mein part pura Bhar Ke Nahin Aata Hai material ka uski Kuchh vajah hoti hai yahi defect shot molding kahlata Ha yah isliye Aata Hai Doston Kyunki bahut bar Jo injection pressure Ham set karte hain vah kam rahata hai ya FIR injection speed kam set ki Gai hoti hai Teesra Karan Hai holding speed kam hone ke Karan bhi short moulding aata hai injection pressure ya holding pressure kam hota hai tab bhi aata hai agar machine ka sahi se nahin liya Gaya Hai tab bhi yah defect Aata Hai Iske alava Agar transfer position sahi se set na ki Gai ho to bhi short shot Aata Hai agar temperature ki value Sahi Nahin set ki gai hai to bhi short aaega agar back pressure bahut kam de rakha hai to short shot aaega Iske bad Agar RPM bahut hi jyada kam hai tab bhi short shot aaega starting Mein RPM ko Badha Ke Rakhna chahie FIR Kuchh der bad aap kam kar sakte hain cooling time ke hisab se Taki refilling Waqt per ho jaaye short shot aane ke aur bhi reason hai jismein ki injection position Kafi kam hone se bhi short shot Aata Hai Kai bar machine ka jo Nojel Hai vah Uska hole jo hai vah Kafi Jyada Chhota hone se short shot aata hai ya FIR machine ki screws se machine ke Nobel ka jo contact Hai alignment hai vah proper nahin hai jisse ki short shot Aata Hai yani ki center out Ho Jata Hai To fir material leakage karta hai ya FIR Kai bar machine ka jo nozal ka tip Hai vah Chhota pad Jata Hai mold ke Nahin Pata Hai tab bhi Aata Hai Agar screw ka ring plunger Fail Ho Gaya Hai To material Wapas machine Mein Chala Jata Hai jisse ki part Bhar Nahin pata hai aur short shot aata hai to Is Tarah Se Jo problem hai molding ki vah inhin chijon ki vajah se Aati Hai
Is problem ko solve karne ke liye Hamen injection speed suitable Deni chahie injection pressure holding pressure holding speed screw RPM temperature aur back pressure ki Sahi value fit Karni chahie part ke hisab se Taki short molding Na Aaye Is Tarah Se Ham is troubleshoot kar sakte hain doston to kaisa laga aapko yah aaj ka blog ummid hai Achcha Laga Hoga Hamare blog se Jude rahiye aur Hamen Baki social media per bhi follow kariye doston agale video agale block Mein Ham aapke liye agale defect ke bare mein Hindi mein baat karenge Taki aapko acche se chijen aur concept Samajh Mein Aaye
