a complete diet (total mixed ration) with sorghum stover (40%) as sole roughage source was prepared and offered to animals under two forms: as mash or as expanded-extruded pellets (eep). these two complete diets were compared with a conventional diet (ad libitum chopped sorghum stover fed separately with concentrate mixture to meet 80% of protein requirements). these three diets were randomly a...

Fabrication of highly dense parts with complex geometry by paste-extrusion-based solid freeform fabrication processes requires a precise control of the extrusion flow rate to dispense material on demand, which is often referred as Extrusion-On-Demand (EOD). The extrusion process for aqueous ceramic pastes is complex and difficult to control due to their non-Newtonian behavior, compressibility a...

Untuk menanggulangi masalah sampah plastik yang terjadi ditengah masyarakat sebenarnya sudah banyak dijual berbagai macam jenis produk mesin pengolah diantaranya adalah extruder. Namun kebanyakan beredar di dalam pengoperasiannya masih mengandalkan insting operator menentukan putaran motor untuk menggerakan screw atau porosnya. Tujuan porosnya dilakukan desain perancangan transmisi roda gigi. D...

The vesicle extrusion method is used for preparing small (e.g., 100 nm diameter) monodisperse (uniform-sized) vesicles. Polycarbonate track-etched membranes with pores generally ranging from 50 to 200 nm in diameter and a hand-held mini-extruder are used for such a procedure. Extrusion through small (100 nm in diameter or smaller) pores also ensures that the vesicle population is predominantly ...

In this paper, we propose a generic concept of ”Flexible Intelligence Machine Control (FIMC)” which acquires control knowledge from the operation data of expert operators and places higher-level automation on conventional-level cnotrol. And we show two practical examples of FIMC including temperature control on the actual jacket tank in polymerization process and automatic start-up operation of...

Passive advection of light particles carried by a high viscosity fluid in polymer processing equipment exhibits complex behavior due in part to the non-linearity of the equation of motion. The particles motion also exhibits sensitivity to the initial positions. A fundamental understanding of the influence of initial positions of particles on the quality and rate of distributive mixing is essent...

Extruder path generation for a new rapid prototyping technique named “Curved Layer Fused Deposition Modeling” (CLFDM) has been presented. The prototyping technique employs deposition of material in curved layers in contrast to flat layers as in Fused Deposition Modeling (FDM). The proposed method would be particularly advantageous over FDM in the manufacturing of thin, curved parts (shells) by ...

The use of 3D printers for manufacturing processes comes with the challenge filament replacement subsequent processes. This aforementioned including environmental problems posed by plastics wastes formed basis current work which is focused on design and construction a simple single extruder production filaments from waste polyethylene terephthalate (PET) rapid prototyping machines printers.
