Vacuum Sealed Molding Process

GUIDED BY, PRESENTED BY,Prof. (Dr.) A. Kharim Kutty, Adarsh B GDean,Dept of ME M13425002MESITAM S8 ME

INTRODUCTION

•Also known as V-Process

•Developed in 1971 in Japan

• It make use of dry sand, plastic film and vacuum pressure for

binding

•No need of shaking out method and equipment to remove the

casting

LITERATURE REVIEW

Rapid fabrication of aluminum shoe mold using vacuumsealed molding processS. Chunga, , Y. Ima, H. Jeong a, D. Jeong b, K. Choc, S. Leed, B. Choi d, H. Choi d feb 2004∗

•Comes under Materials Processing Technology

•Relay on Rapid Product Development in Shoe Industry using V

process

•In general shoes molds are made by cutting process

•It comprises of three parts

•Due to technical difficulties all the three parts are

manufactured by conventional machining process

•This paper suggests to use V-Process

•Shoe mold made by V-Process consist only an Upper and Lower

mold

•V-Process will helps in Rapid Product Development in a Shoe

Industry
