Perancangan Cetakan Injection Molding Hand Press Untuk Produk Slide Piece CVT Menggunakan FEM

Abstract

The development of composite materials in the automotive industry has reached the stage of utilizing natural fibers to pursue relatively low material prices with the same quality. One method for product formation is injection molding. This study aims to design the most efficient mold from a variety of shapes, dimensions, and runner types used with the help of SolidWorks software. The tool used to support the design of the mold is a low-pressure injection molding hand press with a barrel temperature specification of 200 C -250 C, barrel volume of 270 cm3, and an out-of-nozzle diameter of 8 mm. The most efficient design is determined from three multi-cavity models with different shapes. This research produces a two-plate mold with multi-cavity modeling which has a low-pressure parameter of 1.89 MPa and the shrinkage factor is still within the standard range of PPHI material (< 1%).

“…Slide piece sering disebut dengan slider CVT merupakan komponen pelindung yang berada di pulley depan CVT. Proses pembuatan CVT dilakukan berdasarkan perancangan cetakan pada penelitian yang dilakukan oleh Latief et al (2021) [8]. Komponen ini umumnya berbahan plastik yang memiliki kekuatan impak yang baik berfungsi untuk menahan gerakan dinding dalam agar bisa bergeser saat terkena dorongan roller.…”
