Quality System

Home

NIL's quality system is certified with an ISO/TS 16949 Quality System Certificate.

Quality system and personnel is available 24 hours/7 Days/ 52 Weeks. Quality system consists of Quality Manual and procedures. All processes are controlled by computers and/or PLC's and recorded by computers. Each and every action is recoded, and thus, traceable. The table below might give you an idea of our recording system.

Process Controlled By Recording Medium Recorded
Incoming material Head of the Shift Computer By hand
Heat treatment schedules Chief of Sales Computer By hand
Cleaning, drying PLC Paper By hand
Hardening, carburising PLC Computer Auto
Tempering PLC Computer Auto
Tests Quality Control Computer Auto
Outgoing Audit Quality Control Computer Auto
Outgoing material Head of the Shift Computer By hand

REPEATABILITY

The process parameters and the results expected, together with test methods etc. are recorded to the computer. Thus, it is easy to repeat the exact processes, in every coming of the same material.

TRACEBILITY

  • A unique code for each company: Company Code

  • A unique code for each part of each company: NIL Number

  • A unique code for each coming of NIL Number: Incoming Code

  • A unique number for each batch: Charge Number

This system makes a unique and perfect tracebility system work. Just let us know one of these;

  • The date that you have sent your parts
  • Your bill of lading number
  • The date we have send you
  • Our bill of lading number
  • Our charge number (which is attached to each package sent to you)

and our home made software system trace it to the smallest detail.

MEASURABILITY

There is a sophisticated calibration system software (home made) for the test machines. They are traced daily. The results of the heat treatment on each step is tested and recorded.

QUALITY TEST SYSTEM

Every shift has its own Quality Personnel. Results of the processes are tested on each step, by well trained test experts, with (at the beginning of each shift) calibrated test machines, in an environmentally controlled laboratory and recorded to a sophisticated and home made software. The results are accepted or rejected automatically by the software, eliminating human mistakes. It is not possible to go further steps before test results are approved. And it is not possible to arrange a bill of lading if there is a missing test or any rejects.
