Type of Steel Product Available
Quality
Commercial Quality
The commercial quality cold rolled steel sheets and coils are made of carefully annealed low
carbon steel coils. They have a good surface finish, workability and excellent flatness.
Drawing Quality
This quality is used for applications that require drawing properties that are better than those
of the commercial quality. They are produced from high grade materials by carefully
controlled manufacturing process.
[Mycron steel berhad]Quality Control [SMU 3813]

Deep Drawing Quality
Made from strictly selected materials and manufactured with the most exacting quality
controls, this quality has the highest attainable quality for drawing use.
Surface Finishes
Dull Finish (Matte Finish)
This does not have any luster and is actually made rough intentionally so that the lubricant
will stick to it during press forming, thereby facilitating fabrication. This finish is also
suitable for paint adhesion. With these characteristics, cold rolled steel sheets and coils with
this finish are most extensively used.
Commercial Bright Finish
The smooth texture of the surface makes it best suited for metallic plating and coating.
Edges
Edges produced during the hot rolling process in the manufacturing of hot rolled coils.
Slit Edge (Trimmed Edge)
Edges produced by trimming or slitting at the final stage after the cold rolling process.
Oiling
Cold rolled sheet coil are oiled by the Electrostatic Oil Coater at our recoiling line in order to
provide maximum protection against rusting. However, order are accepted for products
without oiling.
DOS coating (FDA approved) are also available for cold rolled steel coils to be used in
making food grade packaging containers.

The Group is confident of the long-term growth potentials, for the manufacturing,
electronic, palm-oil and petroleum industry of Malaysia. All these industries require Cold
Rolled Coil (CRC) as a core component, either in the form of a raw material, or in the form
finished products, like oil drums, and it is the view of the Group, that demand for its CRC
products, will enjoy similar long-term growth prospects. To feed the country’s manufacturing
appetite for CRC, Malaysia has been a substantial importer of CRC, with 2009 showing
CRCrelated product imports of 1.43 million tonnes (2008: 1.62 million tonne). With such a
large amount of imported CRC, the opportunities for the Group, to penetrate new markets,
and play its role in import-substitution, is tremendous. (MSCRC), was incorporated in
Malaysia under the Companies Act on 6 January 1989 and commenced production in June
1990. MSCRC is the first CRC manufacturer in Malaysia and operates from its cold rolling
mill factory located on an 18 acre site located in Shah Alam, Selangor Darul Ehsan.
QUALITY PRACTICES IN THE COMPANY:
1. EHSQ Certification ISO 9001
MYCRON integrated EHSQ Management Systems is a key foundation for its ongoing
performance and sustainable growth. They are certified to ISO 14001 (environment), OHSAS
18001 (health and safety) and ISO 9001 (quality). These are the three internationally recognised
management systems that utilises the PDCA (Plan, Do, Check and Act) process approach for
management of EHSQ functions. Implementation of these standards in all MYCRON operating
sites ensures that health and safety risks, environmental aspect and impacts, and quality systems are
managed with rigor, leading to continuous improvement in their performance.

Commit to a safe, clean and healthy workplace for employees, contractors and visitors;
Comply with all applicable EHS regulations, requirements and their own high standards;
Measure and review their EHSQ performance and set challenging objectives for continuous
improvement towards the goal of zero defects;
Continually improve the effectiveness of their management systems;
Foster an environment where employees take ownership for EHSQ performance by
providing education, training and resources, and by encouraging employee involvement.
Their commitment and focused actions will make them an industrial role model in environment,
health, safety and quality management, and bring them sustainable results.
COMMON PROBLEMS FACED BY THE COMPANY ARE:
I. Production: MYCRON investing to upgrade its milling facility. MYCRON recently
invest in upgrading its sheet and foils milling facility to enable the group to produce
higher value-added products and expand its customer base.
II. Manufacturing Capability: MYCRON faced difficult market condition, which they
will need to enhance their manufacturing capability to build sustainable competitive
advantage and maximizing value for shareholders. This due to the increase of low-
priced imports from Japan. The raw materials (steel ingots) is the highest percentage
of companies’ operating cost (60% - 80%), depends on the price of steel.
III. Finance Risk: The Group is exposed to currency risk as a result of the foreign
currency transactions entered into by any of the Group companies in currencies other
than their functional currency. The Group’s foreign exchange risk management seeks
to protect cash flows and shareholder value by limiting the impact from adverse
exchange movement whilst sharing in the benefit from favourable movements. Aside
from natural hedges, the Group also enters into forward foreign currency exchange
contracts to limit their exposure on foreign currency receivables and payables, and on
cash flows generated from anticipated transactions denominated in foreign currencies.

SUGGESTION TO IMPROVE QUALITY:
a) Control of documents
Having control of documents in a company or organization is essential. Controlling
documents issued is essential to assure the current revision is being followed and also that
no unauthorized revisions are taking place. Control also means a system where changes to
documents can be initiated and by whom. The control of documents also must have a
process where individuals can submit proposed changes based on their knowledge of the
affected subject. In controlling documents there must be some identifying characteristic to
indicate that when someone is looking at it that it is the current one to be followed.
b) Management review
The subject of management review involves a process where management reviews the
system and policies in place to assure one that they are current and are being followed. It is
also the responsibility to review current procedures/instructions and policies to assure that
any changes in process, contractual or other events are addressed within the system.
Contractual changes such as becoming ISO certified will affect how a company does
business and how that is documented applicable to their specific operations.
[Mycron steel berhad]Quality Control [SMU 3813]

c) Identification %26 traceability
Identification and traceability is something that is needed for a manufacturing facility.
Companies who provide products to the public or organizations must have a method of
identifying when a part has been made. Problems sometimes arise after products have been
placed in the hands of customers. Sometimes internal situations identify a problem which
warrants customer notification there needs to be some way of identifying those products
affected. Identification and traceability also affects documents as previously stated and the
traceability factor can be important in a manufacturing environment. One example may be
where contractual requirements were not addressed within the operational instructions and
changes are required to bring the process into compliance. Having traceability such as lot
numbers or process numbers on a manufactured product is a way of segregating the affected
products. Other examples have been where the auto industry has recalled numerous
vehicles with deficiencies within certain manufacturing dates. This is an example of the
benefits of identification and traceability in the manufacturing world.

1. Lean Six Sigma
Focus of Lean Six
Sigma
Lean Six Sigma combines two well-known
approaches the practice of continuous improvement. The
Lean' component of Lean Six Sigma focuses mainly
on the elimination of waste and non-value-added
activities in a process. By eliminating waste, Lean
helps to reduce process leadtimes, inventories and
ultimately costs.
The 'Six Sigma' component focuses more on the
elimination of variation in a process. Many quality
problems and defects are rooted in unstable processes or
processes with excessive variation. By tackling variation,
the Six Sigma methodology helps to resolve complex
quality problems, reduce defects and improve process
capability. Statistically, a process operating at Six Sigma
level is one that generates only 3.4 defects per million
opportunities.
Lean Six Sigma combines the effect and power of two key
strategies:-
1) The focus of Lean is to reduce lead time and
control costs
2) The focus of Six Sigma is to improve quality
and reduce costs.
[Mycron steel berhad]Quality Control [SMU 3813]
12
A Value Based Approach
The Lean Six Sigma continuous improvement process is a value-based approach. Improvement
opportunities are identified by carefully listening to the voices of our customers, employees and
processes. These opportunities are screened through using value-based criteria, prioritized and
finally assigned to project teams led by trained experts. These experts are referred to as Black Belts
or Green Belts. Under the leadership of the Black Belt or Green Belt, these teams applies a rigorous
D-M-A-I-C problem-solving approach to come up with breakthrough solutions.
TPM is another major pillar of MYCRON's overall continuous improvement system. Whereas
Lean Six Sigma focuses on improving speed and quality, TPM focuses on machine and plant
reliability through a process of identifying and eliminating losses. Our TPM journey is driven from
the top and aims at achieving a complete cultural change, from the traditional “I operate – you fix”
operation to one where operators take pride of ownership in their machines.
2. Total Productive Maintenance
TPM Goals:
1) TPM aims to maximize equipment effectiveness.
2) TPM establishes a thorough system of Preventive Maintenance (PM) for the
equipment’s entire life span.
3) TPM is cross-functional, implemented by various departments (engineering, operators,
maintenance, and managers).
4) TPM involves every single employee.
5) TPM is based on the promotion of Preventive Maintenance through the motivation of
management and autonomous Small Group Activity (SGA).
[Mycron steel berhad]Quality Control [SMU 3813]

Holistic Measurement & OEE
All losses that have an impact on equipment performance are measured e.g. machine not being
available when needed; not running at an ideal rate, and not producing the right quality on the first
pass. OEE %( Overall Equipment Effectiveness) is used to measure how productively a machine is
being utilised. In principle, OEE is calculated as: -
OEE = Availability x Performance Rate x Quality Rate
Availability = Required Production Time – All Recorded Downtime
Required Production Time
Performance Rate = Actual Production Rate
Standard Production Rate
Workplace Ownership
Through autonomous maintenance and small group improvement activities, employees
acquire new skills and can detect and rectify minor machine problems before they cause further
machine deterioration and failures. Employees also take greater pride in a safer and cleaner
workplace.
Quality Rate = Good Output
Good Input
[Mycron steel berhad]Quality Control [SMU 3813]
14
Formal Continuous Improvement
With OEE as a measurement index, continuous improvement activities are undertaken to
fix problems at machine centres. Simple problems are directly solved by shopfloor teams
using small group activities. More complex problems are escalated to management and
support staff and resolved using more advanced problem-solving tools.
The main objectives of Autonomous Maintenance are:
1) Machine in ideal condition: Any departure from normal condition must be identified
immediately. Operators are trained to capture abnormalities using the fugue tag
2) Knowledge based work force: Utilising the training and education pillar, workers are
trained to “Know My Machine” with the eventual aim of becoming a knowledge
based worker
3) Cultural change: shop floor operators begin their continuous improvement quest by
rectifying abnormalities, eliminating root causes and making improvements to prevent
recurrence. The eventual target is to maintain and have ownership of a machine which
is in tip top condition
