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 m ....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 steel or aluminium

BASIC INSTRUMENTATION MEASURING DEVICES AND BASIC PID CONTROL


INTRODUCTION
Instrumentation is the art of measuring the value of some plant parameter,
pressure, flow, level or temperature to name a few and supplying a signal
that is proportional to the measured parameter. The output signals are
standard signal and can then be processed by other equipment to provide
indication, alarms or automatic control. There are a number of standard
signals; however, those most common in a ....etc

Design and Manufacturing of Injection Mould for Rotor Assembly



INTRODUCTION

OVERVIEOVERVIE

Injection Moulding requires that the material be heated to plastic state in a barrel and then forced into the mould cavity with a plunger under high pressure. The plasticization of the material in the barrel is facilitated by shear and friction from a rotating screw that also feeds the raw material. In thermoplastics, the material is cooled in the mould until it can be ejected ....etc

injection moulding defects in plastic ppt pdf

. Description
A molded product that is incomplete because the mold cavity was not filled completely.
. Causes
Insufficient injection-molding machine performance (shot capacity, plasticizing capacity, etc.)
Poor material flowability
Gate cross-section surface area is too small. Molded product thickness is too thin.
Poor gas venting.
. Countermeasures

Increase the amount of material feed. If material feed is still insufficient at maximum material feed capacity, change to a l ....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, width, heigh ....etc

Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining thousands of transistors into a single chip. VLSI began in the 1970s when complex semiconductor and communication technologies were being developed. The microprocessor is a VLSI device. Before the introduction of VLSI technology most ICs had a limited set of functions they could perform. An electronic circuit might consist of a CPU, ROM, RAM and other glue logic. VLSI lets IC designers add all of these into one chip.
