Manufacturing quality involves reducing waste, maintaining high product quality, and accelerating production. This is achieved through techniques like just-in-time manufacturing, total quality management processes like Six Sigma that aim for zero defects, and computer integrated manufacturing. Quality is also ensured through steps like defining manufacturing processes, identifying areas for improvement, implementing solutions, and evaluating results. Effective after-sales service including repairs and handling customer complaints is also important for customer satisfaction and sales.

1. Manufacturing Quality
Presented By

2. Introduction-Manufacturing
 It involves making products from raw
material by various processes or
operations. It is complex activity, involving
people who have wide variety
machinery, equipment and feeling with
various levels of automation, including
computer, robots and material handling
equipment with a range of
knowledge, skills.

3. Method of Manufacturing
 Method of manufacturing have changed from the rigid, push-oriented
production principles of the early 20th century to more flexible, pull
principles.
 Assembly line manufactures used to push mass production ahead
based on estimates of future demand.
 The modern manufacturing method have three main
considerations:-
1. Waste reduction is done by following several techniques:
a) Just-in-time manufactures:- suppliers to keep process moving
and scheduled at factory place just in time for them used in
production.
b) An automatic request for new suppliers when supplies are
running low. these alerts are called kanban. These are computerized.
c) Just -in-sequences:- supplies arrive at the factory at exact moment
with in the manufacturing sequence. Give a standstill if supplies few
minute late.
d) Total productive maintenance:- avoid stopping production.
Some factoring wait until the repair minor issues with their
machines at the end of the day.

4. a) Quick response manufacturing:- customer
request for a product and the final delivery for a that
product as brief as possible.
b) Cellular manufacturing:- separates the factory
floor in to different section and machines are placed in
a order so that material flow naturally towards the
competition of a product.
c) Single-minute exchange of Die:- is reduce waste
time. Even between projects smed focuses on
changing the factory premises from working on an old
product to new product as quickly as possible.
2. Quality of a product has to be maintained:- a
manufacturing process is given a sigma rating based on
the percentage of its product yield being defect free.
A one sigma rating designates a process with a yields
of 31% and six sigma rating is a processes which is
nearly perfect that 99.99% defect free. Thus, every
company wants six sigma for all manufacturing
process to find out and remove defects.

5. define, measure, analyze, design, verify(DMADV):-
it is a methodology to analyzing of customer
demand ,manufacturers plan ahead and try to
design ways to avoid defects in first place.
Critical to quality and quality function:-
deployment are two concept try to pinpoint the
element of a product that are most important
to the customers and translate those needs
in to manufacturing strategy that focuses on
getting the critical elements exactly right.
. suppliers, inputs, process, outputs
customers(SIPOC) is followed to allow
manufacturers to trace the life cycle of their
products from suppliers to customer and identify
problem areas.

6. 3. Accelerate production:- production is
accelerated to make sure products are made
available and demand is met.CAM and CAD
should be adapted. Cad is used for design of
production process and Cam is guide parts
through those process with robots and computer
controlled Machine.
CIM creates a network of computers that
observe and operate the manufacturing process.
Computer can monitor every step of production
for defects and change the actions of machine
almost immediately leading to flexibility.
Finally , the three major goals of reducing
cost, maintaining quality, and accelerating
production are achieved through combined
efforts of lean manufacturing theories, six sigma
methodologies, and flexible processes.

7. Steps for quality manufacturing
 Improving quality manufacturing processes leads to decreased
waste, better quality products, and an overall improvement in
customer satisfaction.
 To ensure the following steps are completed and taken from
beginning to end:
1. Actual process:- name process, and its purchase, its starting
ending points, inputs and outputs and overall requirements, and
customer and suppliers who will be affected by this process.
2. Areas of improvement:-take a random sampling. It make sure
disintegration of parts and loose fastness and so forth.
3. Solution for the problems- consult with specialist and
brainstorming, feedback
4. Detailed solution:- budget
5. Put plan into action – involve everyone from highest level to
lower level.
6. Evaluate-improvement process as a whole .

8. Inspection and control of product
 The quality appraisal may take the form of
physical inspection of entire product or a
small part of it. the inspection of a small
portion, is termed as ‘sampling inspection’.
1. 100% inspection
2. Sampling inspection
3. Sampling plan

9. Quality in sales
 Purchasing decisions are based on the price and the
quality of a product .it would be first consideration
otherwise sale of a product may suffer if priced too
high. Even though quality of a product is good quality.
 The quality reputation of a company is a great asset
which makes selling very much easier and also help in
growth and diversification.
 If every one in the company make it his business to
please the customer then quality image become
longer.
 Methods of establishing a quality reputation are:
 Sold only those product which can fully meet
customer expectation.
 Prompt and courteous adjustment of warranty
claims, in case of product fail.
 Effective after sale service.

10. After-sales service
 The reliability and maintainability are important
quality parameters. effective after sales service is an
essential element in ensuring reliability and
maintainability.
 It not only cover maintenance and service facilities,
but also all post-sale efforts to ensuring maximum
customer satisfaction.
 Important aspects of after sale service are:-
i. Customer education
ii. Maintenance and repairs service whenever needed
iii. Importance to customer complaints

11.  Repairs facilities are set up by the
servicing and repair centers managed by
the company.
 It may provide license to other repair
agencies to provide those services on its
behalf.

12. Guarantee
 The guarantee of quality is for benefit of the
customer, if the product purchased turns out
to be defective.
 It is an undertaking by the selling company
that it will replace the product free of cost
or refund the money.
 It include terms and conditions that should
be clear and unambiguous.
i. Validity period
ii. Manufactures liability
iii. Guarantee claims procedure
iv. Guarantee invalidation condition

13. Analysis of claims
 The investigation of complaints involves
thorough technical knowledge of the
product.
 Guarantee claims may be investigated by
the quality control department if decided
 Time should not be longer because it
makes further annoyance to the customer.
 Minor claims being settled by service
centre and major by the company itself.

14.  The advisor can play with the design
feature but quality of conformance must
be based on faith .
 Design , production and distribution aim
to service the satisfaction of the
customer needs.
 Feedback play vital part in building quality
of a product. It should be continuous in
the organization
