How It Runs, Step by Step
Define the list
Send the OE numbers, the alternates you already hold, or the vehicle and engine code. Anything in the 136-number catalogue is quoted directly.
Identify the part
Archive photographs, recorded alternate numbers and application notes are checked against your list before anything is quoted.
Confirm by sample
Where a number is ambiguous, a sample or a dimensioned photograph settles flange pattern, drain position and sensor boss before tooling time is booked.
Select the process
Stamped steel or cast aluminum, drawn, die cast, sand cast or gravity cast, according to what the original part is.
Produce
Scheduled against the stated annual oil pan capacity of 500,000 pieces.
Inspect
Checked under the quality systems recorded on the original site, ISO 9001 and TS 16949.
Pack and mark
Carton specification, labelling and marking agreed per programme.
Ship
Consolidated so long-tail references travel with the volume lines.
Outcome
One factory, one packing standard and one lead time across a whole number family.
Every figure and capability named on this page is one RUIFAN recorded on its original site. Where a detail was never recorded, it is agreed per programme rather than stated here.
What the factory records
- Founded 1994 in Ruian, Zhejiang
- Stated annual oil pan output of 500,000 pieces
- Quality systems recorded as ISO 9001 and TS 16949
- Deep and shallow draw stamping; die, sand and gravity casting
- Chrome plating and vacuum metallization
- Development of oil pans and aluminum castings from customer samples or drawings
Background Reading
Oil Level Sensor Hole Variants and Why They Matter
Why two pans with almost the same number are not interchangeable when one has an oil level sensor boss and the other does not.
Upper and Lower Two Piece Oil Pans
What an upper pan does that a lower sump does not, and how to avoid ordering the wrong half of a two-piece system.
Die Casting Sand Casting and Gravity Casting for Engine Parts
The three casting methods listed in the RUIFAN process sheet, what each one is good for, and how the choice shows up in the finished part.
Questions About Replacement Oil Pan Programmes
How long does replacement oil pan programmes take?
Lead time was not recorded in the archived catalogue and is confirmed per programme, because it depends on whether tooling exists, how many references are in the order and where it is shipping.
What do you need from us to start?
For catalogue references, the number list, quantities and destination market. For anything not in the catalogue, a sample, a drawing or a dimensioned photograph.
Who owns the tooling?
Tooling cost, lead time and ownership are agreed in writing before any work begins. Nothing on that is assumed.
Can this run alongside a catalogue order?
Yes, and it usually should. Consolidating is what makes low-volume references economic to produce and to ship.
What quality systems apply?
ISO 9001 and TS 16949 are the systems RUIFAN recorded on its original site. Certificate numbers and validity dates are supplied on request.
