Injection molding is one of the most common processes which are used for manufacturing different plastic parts. This method includes 3 continuous steps: filling of the mold, cooling and driving the part out. A wide range of plastic and Non-Plastic materials can be used as raw material in this process. One of the most important advantages of this way of production is that it is very economic. In...

P lastic surgery is one of the most ancient forms of surgery, and its roots can be traced back to the time of Sushruta, the father of surgery (600 BC), 1 who is credited with performing the first ever reported plastic surgical procedures. The name, however , defies a clear understanding and an appropriate definition that could cover the entire scope of activities performed at the present moment...

This paper describes the optimization of dimensions individual injection mold runner system plastic part used as frame for various devices in transport means. Nowadays, great emphasis is placed on production time and finances associated with design production. As a result, simulations are being employed increasingly. aims to describe optimum size shape sprues runners required proper filling sim...

This work is aimed to present an innovative technology for the reinforcement of beams for urban furniture, produced by in-mold extrusion of plastics from solid urban waste. This material, which is usually referred to as "recycled plastic lumber", is characterized by very poor mechanical properties, which results in high deflections under flexural loads, particularly under creep conditions. The ...

Plastic injection molding is a widely used manufacturing method in the automotive and machinery sectors. The design manufacture of appropriate mold needed to plastic product with this are difficult, time-consuming, costly process. Due developing technology increasing quality requirements, remains insufficient, especially for sensitive intricate parts that will be manufactured low numbers. In ad...

Macro-scale revolute joints can be formed by first molding the hole and then molding the pin inside the hole. As the pin shrinks during the solidification process, it moves away from the hole and provides the clearance for the joint to function. The value of clearance in the macroscale joint can be controlled by carefully selecting the process parameters and the material for the pin. However, i...

Sol–gel-based carbon xerogels possess very promising properties for pollution abatement, using processes that associate adsorption and on-site electrochemical oxidation. However, combining a high exterior surface area (for efficient diffusion) monolithic shape (necessary processes) poses challenges. In this work, the of was contrived by use 3D-printed molds. Several parameters were optimized: c...
