In this study, we focus on making a double-sided metal plate with an internal structure, such as honeycomb. The stainless steel powder was used in the metal injection molding (MIM) process. The preliminary studies were carried out for the measurement of the viscosity of the stainless steel feedstock and for the prediction of the filling behavior through Computer Aided Engineering (CAE) simulati...

The overall goal of this study is to propose a new approach simplify the recycling process for producing high quality material from waste beverage bottles and other sources at lower cost by using mechanical chemical reactions inside injection molding machines in one-step process. water soft drink are made PET material, while caps mainly HDPE. blends HDPE incompatible. resulted has poor properti...

Bone, at the ultra-structural level, is a composite with mechanical properties that can be matched by man-made composites. It serves as the template for developing bone replacement materials. Research on biomaterials analogous to bone was started in the early 1980s by incorporating bioactive particles into biocompatible polymers to produce bone substitutes. Hydroxyapatite reinforced high densit...

A low-pressure plasma surface treatment of polymeric powders was carried out in a circulating fluidized bed (CFB) reactor (10 mm-I.D. × 800 mm-high) with CF4 glow discharge. The effects of solid circulation rate, treatment time and radio frequency (rf) power of plasma on fluorination of high-density polyethylene (HDPE) powders have been determined. X-ray photoelectron spectroscopy (XPS) and the...

The authors introduced waste plastic pyrolysis oil (WPPO) as an alternative fuel characterized in detail and compared with conventional diesel. High density polyethylene, HDPE, was pyrolyzed in a self-designed stainless steel laboratory reactor to produce useful fuel products. HDPE waste was completely pyrolyzed at 330-490°C for 2-3 hours to obtain solid residue, liquid fuel oil, and flammable ...

High-density polyethylene (HDPE) is one of the most popular plastics used in industry. Although it replaces many natural resources, due to low cost and easy processing, its ever-increasing wastes make harmful for environment. Thus, processes are order recycle it. In present study, properties recycled HDPE (r-HDPE) compared virgin investigated. The structural studies performed by X-ray diffracti...
