WQD2011 - KAIZEN - EMAL - To eliminate the chances of breaking of PC charging...Dubai Quality Group
Kaizen case study submitted by Emirates Aluminium during 3rd Continual Improvement & Innovation Symposium organized by Dubai Quality Group's Continual Improvement Subgroup to celebrate World Quality Day 2011.
When I searched for the recent technology and developments in SLA/ DLP printers, I found limited resources that speaks about the existing problems, but there is ample of resources that talk about the technology and its basics. Very limited open source material is available online related to this topics. A candidate without the firsthand experience of these printers will never be able to understand the limitations. Hence these efforts are made to make the problem statement more open source to the people who cannot actually have the privilege to experience such printers first hand. This paper talks about the normal problems one faces while operating this printer, cautions and maintenance aspects I hope all the information provided in this report shall and will be used for the development of existing technology.
My name is Elena Long. I am associated with matlabassignmentexperts.com as an Matlab Assignment help expert for the past 4 years and have been helping students with their assignments. I have a Ph.D. in Mechanical Engineering, from McGill University, Canada.
We will go through how to analyze a design with Simulation CFD from beginning to end. We will start at the Inventor model and end at visualizing the results. In addition to seeing the actual workflow we will talk about how simulation tools can be used throughout the life of a design project, from early concept to final testing.
Engineering Guidelines to Designing Plastic Parts for Injection MoldingJaycon Systems
At Jaycon Systems, we have chosen to use injection molding as the main manufacturing process to bring plastic products to life.
However, injection molding is not simple. Engaging in such process requires an extensive knowledge about its machinery and process.
In this presentation, we will show you some of the aspects we take into consideration when designing plastic parts for injection molding so we can save our customers time and money in the long run.

Train production and design personnel to analyze, identify and correct 11 of the
most common and costly part defects!
N Expand problem-solving capabilities
N Improve quality
N Cut reject rates
N Maximize profits
Recommended For: Set-up Personnel, Foremen, Process
Engineers, Production Supervisors, Molding Managers
This program teaches injection molders, mold designers and part designers how to
identify and correct the most common and costly molded part problems.
Part defects are described and analyzed to show how each develops. The machine
control adjustments and/or tooling and part design changes necessary to correct
specific defects are explained in detail.
Also included is an explanation for the cause and effect method of problem analysis –
a very valuable technique for analyzing and solving all types of production and
management problems.
11 Most Common Molded Part Defects
1 Voids: Small holes in thick sections caused by plastic shrinkage.
2 Sink Marks: Small depressions in molded part surfaces opposite thick sections,
caused by internal stresses as the plastic cools.
3 Short Shots: Undersized molded parts due to incomplete cavity filling from too little
plastic, poor venting, mold or melt temperature problems, faulty part or mold design.
Lessons
4 Flash: Thin ribbon of excess plastic formed when plastic is forced between parting
lines in the mold. Harmful to the mold and requires trimming operation for removal.
5 Weldlines (Knit Lines): Lines where plastic streams meet during mold filling,
causing unsightly appearance and structural weakness.
6 Splay (Silver Streaks): Surface defect that occurs when gas bubbles are
dragged along the plastic surface as it fills a cavity.

2. Injection Molded Part Problems & Solutions with SkillBuilder
11 Most Common Molded Part Defects (cont’d)
9 Warp: Molded part distortions from uneven stresses in the part caused by faulty
molding conditions inside the cavities.
10
Cracks and Part Breakage: Weak molded parts susceptible to cracking and
breaking, as a result of incorrect molding conditions that can cause five different types
of cracking problems.
11 Controlling Molded Part Dimensions: Off-spec parts caused by dimensional
changes throughout the part, in specific areas or directionally.
SkillBuilder Lab Lessons for Injection Molded Part Problems & Solutions
Solving a Burnmark Problem
The purpose of this lesson is for the student to learn some of the available
molding techniques that will help eliminate a burn mark on a molded part.
Molding to Precise Dimensional Tolerances
Conduct experiments using those machine controls which affect final part
dimensions to lead the participant to a greater understanding of precisely
controlling part dimensions.
Controlling Flash on a Molded Part
This SkillBuilder lesson explores all the possible solutions for eliminating
flash on a molded part including, high or low melt and mold temperatures,
high packing and holding pressures, unbalanced pressure distribution in the
mold, parting line damage or too deep of a vent channel.
Solving Sinkmarks on a Molded Part
This will challenge the student to solve this problem in a variety of different
ways. Both mold temperature and injection pressures are experimented
with to demonstrate to the user more than one possible solution to
the problem.
Identifying and Solving Voids in Molded Parts
Here the molder is allowed to adjust machine controls to create, then
solve each problem. In this way a deeper understanding of the problem
is realized.
Minimizing Weldline Formation and Appearance
The purpose of this SkillBuilder lesson is to show molding techniques on
how to reduce and even eliminate the visual appearance of weldlines
on a molded product.
