Abstract

This article discusses the design process of a chocolate crusher machine based on VDI 2222. The design activities begin with identifying the needs and demands of the customer until finishing the solution for the customer in the form of a design work drawing in technical documentation. The proposed method is validated in a case study of making a chocolate chopper machine design. The machine generally functions as a separator between the cocoa beans and the shell of the seeds which have been chopped in such a way as to produce the required dimensions. At the planning stage, identifying the machine's need is to be able to chop the cocoa beans until the smallest grain has a maximum dimension of 4 mm. Three alternative functions are given and assessed as a result of the conceptualization stage. Evaluation is given to the draft design by considering the material, manufacturing and maintenance aspects. At the completion stage, technical documentation in the form of detailed work drawings is produced. By setting the rotating speed, a chocolate crusher can make beans with dimensions of 2-4 mm and production capacity is about 600 kg/hour.

Abstract

Penelitian ini membahas tentang Perancangan Cetakan Injeksi Plastik Two Plate (Slider with Reciprocating Lifter) untuk Produk Battery Cover Syringe Pump. Produk Battery Cover Syringe Pump ini memiliki bentukan slider pada bagian bawah dan lifter pada bagian dalam dan bentukan snap join pada bagian atas yang harus melakukan perhitungan agar dapat memastikan apakah dapat diejeksi dengan paksa atau harus menambah konstruksi menggunakan (reciprocating) lifter agar produk tidak mengalami kerusakan. Dengan melalui proses perancangan yang telah dilakukan, dapat disimpulkan mengenai konstruksi yang dibuat. Dari metode yang telah digunakan, rancangan dapat berfungsi dengan baik, dan dihasilkan dokumentasi teknik berupa gambar susunan dan gambar bagian.
