The remanufacturing process

Automotive remanufacturing - Standards and legislation

As automotive remanufacturers, we are making progress. Europe’s End of Life Vehicle Directive means that customers are encouraged to reuse all salvageable materials at the end of the product lifecycle.

Automotive remanufacturing needs clear legislation, but in the field of automotive remanufacturing, there is still no legislation that distinguishes the use of a fully tested, OE quality part from a part salvaged from a scrap yard. This needs resolving, and fast for the safety of road users and to protect the reputation of the automotive remanufacturing industry.

  • We need to clearly define the term ‘remanufactured’. There is a big difference between a reused, a refurbished or repaired part and remanufactured part
  • CLEPA defines a remanufactured part as: ‘fulfilling a similar function to the original part. Manufactured using a standardised industrialized process in line with specific technical specifications. The industrialized process incorporates defined core management standards. A remanufactured spare part is warranted as a new spare part.’

A definition completely in line with TRW’s remanufacturing philosophy. And we are passionate about spreading the word.

  • We need a review of the tax treatment of these products
  • We need a CO2 credit for the automotive remanufacturers

It’s TRW’s priority to lead the way and to be a voice for the remanufacturing industry. We are working hard with key Associations such as APRA and CLEPA who have a responsibility and key role to play in leading industry change and promoting the issue of automotive remanufacturing with the EU Commission.

Automotive remanufacturing – the process

  • Sorting
    We sort the incoming old parts and identify them by part number. Damaged or incomplete parts are not used.
  • Automotive remanufacturing and testing
    The old components are completely disassembled and rebuilt achieving an as new condition. Parts that can’t be remanufactured are replaced by corresponding original or equivalent parts.
  • Assembly
    The as-new individual parts are assembled to TRW’s specifications. Permanent interim checks and final testing guarantee that TRW’s high quality standards are 100% met.
  • Packaging
    All products that go through TRW’s remanufacturing process are securely packed for transport, warehousing and sales.
  • Logistics
    TRW stores the products until ordered and provides worldwide distribution.


Core handling and returns

The ‘raw material’ for automotive remanufacturing isn’t manufactured. It is sourced like a ‘raw material’ from salvage yards or returned by garages.

Only components returned in a suitable condition and following our strict returns procedures are suitable for remanufacturing. Parts that are removed by brute force or have been dropped or badly treated upon removal are usually unsuitable for automotive remanufacturing.

TRW is working in conjunction with other well-known names in the automotive remanufacturing industry and industry body CLEPA, to identify the perfect returns solution for your business.

When a part has been returned to TRW in a suitable condition, the deposit value is credited to the garage.


Testing remanufactured parts - safety first and foremost

All TRW’s remanufactured automotive products are safety critical – and we take no chances with the safety of any of our parts.

Any core considered for our automotive remanufacturing process must pass a strict selection process – if it doesn’t make the grade, then it isn’t remanufactured. Simple.

And no remanufactured product leaves a factory with the TRW name on it until it has gone through the same gruelling testing schedule as our new OE product.

The very latest technology and software is used in the remanufacturing process for all TRW’s products to test for performance and safety.


Automotive remanufacturing – monitored quality, without compromise.

We can detect even the smallest of hairline cracks in rebuilt steering racks and vigorously test the strength of our remanufactured calipers.

In the remanufacturing process for rebuilt steering gears, we use the realisation of the Poka-Yoke idea to avoid errors. This means that every examination step needs to be finished successfully before the remanufactured steering gear is released to the next. This method also contributed to Toyota’s worldwide success.

And with all our automotive remanufacturing, a Failure Mode and Effectiveness Analysis (FMEA) is carried out to uncover possible failures and identify improvements at the earliest possible stages.


Pace of technology and development

Due to the development of technology, automotive remanufacturing is at a critical stage today.

There is huge scope for the future of remanufactured electronics and mechatronics – and this is an area where TRW can and will lead the way.

At the top of the technical systems ladder, TRW is in the optimum position to capture this intelligence and transfer it to this element of the market
