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

INTRODUCTION
An Injection molding machine, also known as an injection press, is a machine for manufacturing plastic products by the injection molding process. It consists of two main parts, an injection unit and a clamping unit.
Injection molding machines can fasten the molds in either a horizontal or vertical position. The majority of machines are horizontally oriented, but vertical machines are used in some niche applications such as insert molding, allowing the machine to take advantage of gravity. There are many ....etc

Plastic Injection Molding



Plastic Injection Molding

It is a manufacturing technique for making parts from thermoplastic and thermoset materials
In contrast to the extrusion (which makes continuous parts of constant cross section), injection molding make discrete parts (with complex and variable cross section)
Molten plastic is injected at high pressure into a mold, which is the inverse of the desired shape.
The mold is made from metal, usually either ....etc

How to choose plastic injection molding machine

How to choose plastic injection molding machine
Typically, the important factors when choosing plastic injection molding
machine include mold, product, molding requirements and so on. Therefore,
you must collect or have the following information before making a choice:
mold dimension (width, height, thickness), weight and special design; types
and amount of the plastic (single or multiple plastic materials); dimensions
and weight of injection molding product (length, w ....etc

Abstract :

This project is on Plastic grinding machine which is an electrochemical machine used for granulating waste of plastic into small parts that can be reused for recycling in the same process as a fresh raw material . This minimizes the reduction in the production process and cost effectiveness. It is working on the principle that the raw material is cut by the shearing force on the material between fixed and rotary blades. The small cut pieces pass out from the sieve plate fixed in the body.

This machine has been used i ....etc

A BRIEF STUDY ON PLASTIC INJECTION MOLDING PROCESS

ABSTRACT:

Injection molded components are consistently designed to minimize the design and manufacturing information content of the enterprise system. The resulting designs, however, are extremely complex and frequently exhibit coupling between multiple qualities attributes. Axiomatic design principles were applied to the injection molding process to add control parameters that enable the spatial and dynamic decoupling of multiple quality attributes in the ....etc
