Quality Control Activities
HSS Otomotiv ve Lastik Sanayi A.S. quality control activities which are included
in Quality Management System are executed by Quality Management Department and the
other related units.
Quality Management Process
Internal Audit Activities
Control Activities in Quality Management Process is performed by means of annual
audits that include all units in quality system. Those audits provide all the items
of related system standards, all the related units and the items of the units. Audits
are performed according to annual audit plan in the following intervals:
System audit is performed two times a year by the audits who are independent and
assigned by Management representative.
Process Audit is carried out for all the processes twice a year by means of corresponding
audits held by independent units.
Product Audits are carried out according to product audit plan and needs concerning
internal quality problems, new product activities and plans for products determined
by technical facilities unit.
Work Safety Audits are made every two week; working environment is supervised and
determined if there is any situation that might jeopardise work safety.
However, for these periods specified above, the intervals between audits can be
changed or rescheduled on account of customer complaints, alterations in the organization,
and internal or external quality deficiencies in quality system.
Failure Prevention Activities
1. Precautions for preventing failures that have to be taken before the occurrence
of failures (Precautions against Failures): As a consequence of the audits of the
units, a team is made up in order to determine the possibility of failures that
are likely to be made by related units. An analysis of possible failure is done
and the results are fixed to a notice board. Supplementary techniques can be used
such as brainstorming and fishbone in order to try to develop ideas and think of
ways of solving problems and these techniques can be used to determine precautions
against failures to put into practise. The effectiveness of precautions against
repeated failures can be audited by related units and Unit Quality Chiefs. Eventually
prevention activities are discussed in Management Quality Meeting.
Failure Modes and Effects Analysis (FMEA): When a new product is put into production,
when process alterations are made, and when an important quality problem occurs,
Failure Modes and Effects Analysis (FMEA) is decided to be made. Afterwards technical
design, process flow charter, product tree, operation cards, control instruction
and plans are arranged and then Failure Modes and Effects Analysis (FMEA) Team is
chosen. Process intervals are determined in the Failure Modes and Effects Analysis
(FMEA) meetings and activities. Definitions of examinations concerning production
process and production function; process phases, functions and the determination
of functions of all parts and characteristics that fulfil the functions are FMEA
Team’s responsibility. Failure modes, effects, causes and control processes are
determined and recorded in a form by FMEA Team through examining the tables about
probability, strength, inventiveness points. After the date of corrective and preventive
actions and authorities have been determined, the predictable risk priority indicator
is determined and when the risk priority indicator is under 100, corrective and
preventive actions will be set into progress. When an investment has to be made
in corrective and preventive actions, investment approval will be received by relevant
unit. The effectiveness of corrective and preventive actions is inspected by relevant
units and FMEA results are considered in management quality meetings.
Quality Activities in Purchasing Process
Quality Control Activities begins with Supplier Determination Activities in Purchasing
Process. ISO 9000:2000, ISO/TS 16949 is requested from suppliers as the basic requirements
of quality system. If the supplier fulfils those system requirements the supplier
will be beyond the scope of quality system progress. Supplier who is within the
scope of progress is audited in accordance with “Supplier System Audit” at first
to find out the status of supplier in the scope ISO 9000:2000 – ISO/TS 16949. An
interview is held with supplier and a process programme is requested. If requested
by supplier HSS Otomotiv Quality Management Unit gives education to supplier and
support them in progress programme. The progress is audited by means of system audits
periodically (at least annually)
The first control in Purchase Process is measurement control and first sample control
which includes material, function, steadiness phases. The determination of the appropriateness
of first samples (first sample control report) phase is followed by making the order
for initial mass production and administrative approval of initial mass production,
access quality control of initial mass production and serial purchase phases.
Access Quality Control Administrative Approval/Control: The sum of order, deadline
date and identification control are checked and if the shipped materials are the
materials that needs technical approval such as mould, axle, computer parts (hardware
or software); materials are delivered notifying related (expert) units.
In the controls that are held in accordance with access quality control plan the
products which are examined by access quality control unit are measured and the
results are recorded in form of consignment measurement.
Control Activities in Production Process
1. Preproduction control work obligations: Work obligations are distributed to workers
and checked with preproduction control form of preproduction process terms by Unit
Manager, Unit Executive or Shift Executive.
2. Controls during Production: Cord fabric cutting, stainless steel wire, rolling
and vulcanizing process, activities are carried out according to material and production
information, control plans and work obligations. In case of inappropriateness during
the production controls, the problem is resolved by starting corrective and preventive
actions in accordance with relevant process procedure. When the problem cannot be
determined or when team-work is required, the problem resolving techniques are used
such as brain-storm CEDAC – 8D methods.
3. The Final Decision Committee Working: The Final Decision Committee Working System
is used in every process from access quality control to final product. The Final
Decision committee is a committee which takes place when workers cannot decide finding
solutions by current control plan, other documents and personal experiences against
problems that might affect quality. The Final Decision Committee is charged to find
solutions towards changeable situations, to take emergency precautions, to decide
to use the material and/or product in spite of the bias when the conditions do not
affect quality.
4. Production Final Control: Control Plan in production is the process of examining
air springs in accordance with fault searching technique after vulcanization. At
the end of Production Final Control the air springs which are separated for the
Final Decision Committee or renovation or separated as scrapped items are examined
again by Unit Manager or Shift Executive and the damaged parts are marked and sent
to renovation unit. The renovated air springs are vulcanized and sent to the Final
Decision Committee section. The air springs which are regarded as scrapped items
by the Final Decision Committee are examined again and marked and sent to scrapped
items section. If the air springs are sent to shipping section with metal parts,
metal assembly is made according to metal assembling instructions. After assembling
metal parts, air springs are examined according to sticking, perpendicularity, leakage,
eye, axis deviation criteria. “Leakage Test was made”, “Axis control was made” labels
are placed on air springs afterthe examination
and the air springs are sent to shipping unit.
Control Activities in Shipment Process
In air spring control which is held according to Sampling Plan and Instructions,
controller number labels are placed on air springs up to the amount of indicated
number of samples or indicated number of samples in product control rate.
Air springs, which are ready to transfer to sales
depertment, are controlled 100% by a team which includes Production Manager and
Shift Supervisors according to failure inspection key two times a month (without
giving prior notice).
Results of the controls are recorded in stud
control investigation and recording form. The products, which are produced and
readied for delivery by production depertment, are received with “Product Delivery
Receipt”. The in box quantity and the correctness of products received are checked
by Shipment Department according to shipment control plan. The products are transferred
to trackback form after quantity verification and controls and shelved in the stock
area filling in the control cards.
