Blow molding


1. INTRODUCTION

Blow molding, also known as blow forming, is a manufacturing process by which hollow plastic parts are formed. It is a process used to produce hollow objects from thermoplastic.
In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and stretch blow molding.
The blow molding process begins with melting down the plastic and forming it into a parison or preform. The parison is a tube-like piece of plastic with a hole in one end ....etc

1. INTRODUCTION
Rocket engines that work much like an automobile engine are being developed at NASAâ„¢s Marshall Space Flight Center in Huntsville, Ala. Pulse detonation rocket engines offer a lightweight, low-cost alternative for space transportation. Pulse detonation rocket engine technology is being developed for upper stages that boost satellites to higher orbits. The advanced propulsion technology could also be used for lunar and planetary Landers and excursion vehicles that require throttle ....etc

Concept of Cement

The word ËœCEMENTâ„¢ may be defined as a substance, which can join two or more pieces of same other substance together to form a unit mass. Cement is a fine powder which when mixed with water and allow to set and harder can join different components together to give a strong structure mechanically. Thus cement can be used as founding material for bricks or for founding solid particles of different sizes (rubble masonry ) to form a monolish.
It was about 150 years ago or so that ËœCem ....etc

ABSTRACT
Steam generators are widely used in industries for several purposes like power production, processing, heating etc. In industry steam generators are the major fuel consumers. In a normal steam generator about 4% of hot water is wasted as blow down. Due to this, a large amount of heat energy is wasted. This project aims to bring a heat recovery system to prevent heat losses, so that a large savings can be made. So in ths a heat recovery system was designed to ....etc

E85 is an alcohol fuel mixture of 85% ethanol and 15% gasoline, by volume. ethanol derived from crops (bioethanol) is a biofuel.

E85 as a fuel is widely used in Sweden and is becoming increasingly common in the United States, mainly in the Midwest where corn is a major crop and is the primary source material for ethanol fuel production.

E85 is usually used in engines modified to accept higher concentrations of ethanol. Such flexible-fuel engines are designed to run on any mixture of gasoline or ethanol with up to 85% ethanol by volume. Th ....etc

AUTOMOBILE EMISSIONS CONTROL AND MONITORING BY MONOPOLE MAGNETIC DEVICE AND REMOTE SENSING TECHNOLOGY
Abstract
Monopole magnetic device and Remote Sensing Technology (RST) are used to monitor and control automobile emissions to prevent the pollution and protect the environment. Monopole magnetic device reduces the level of noxious gases in exhaust fumes of vehicles. The carbon monoxide (co) level is reduced almost zero in the vehicles. It also claims a substational reduction in hydrocarbon emission in all the vehicles. T ....etc

Abstract—The pervasive adoption of IEEE 802.11 radios in the past decade has made possible for the easy Internet access from a vehicle, notably drive-thru Internet. Originally designed for the static indoor applications, the throughput performance of IEEE 802.11 in the outdoor vehicular environment is, however, still unclear especially when a large number of fast-moving users transmitting simultaneously. In this paper, we investigate the performance of IEEE 802.11 DCF in the highly mobile vehicular networks. We first propose a simple yet accu ....etc

Abstract

the present paper the problem is discussed on Tractor Engine Assembly & Testing. It has been seen that during the engine testing most of the time some engine fails. That means they may have a problem of seizing. In fact, the seizure of the engine is not taking place suddenly but some type of warning given by engine during testing conditions in terms of white smoke. In ....etc
