Why foundries lose repeat business: a register for rejections, delays and replies

Why a foundry's regular buyers quietly cut its schedule after a rejection or a late lot, and how a one-page register of every problem and reply becomes a tool for winning the next order.

The pump maker that has taken your casings for years releases its next schedule, and your share is smaller. Nobody calls to say why. Look for the reason in the last few problems. A lot of casings showed blowholes after machining. A dispatch slipped while the furnace was relined. A rejection email waited three weeks for a reply. Repeat casting orders depend on how the last problem was handled. Keep one register of every rejection, delay and complaint, with the date you replied and what you changed, and take it to the buyer before the next schedule is decided.

What the buyer remembers when the next schedule is split

The defects that hurt most are found in the buyer's machine shop, not at the gate. The boring bar opens up a blowhole or a sand inclusion. A hard spot breaks an insert. By then the machine hours are spent, and some buyers debit you for those hours as well as the casting.

His quality engineer remembers two things about it: how many came back, and how long you took to answer. If the buyer keeps a vendor rating, both go into it.

A delay you warned the buyer about is an inconvenience. One discovered when the truck did not arrive is a planning failure in the buyer's own plant.

Why the foundry forgets what the buyer remembers

Each problem reaches a foundry through a different door. The debit note goes to accounts, the WhatsApp photo of the blowhole to the supervisor, the call about the late lot to the owner. The rejected castings come back weeks later on a challan and sit in a corner of the fettling shop.

Nobody joins these up. So the foundry cannot answer the question the buyer is silently asking: is this supplier getting better or worse?

The register: one row per problem

Keep it as a shared sheet. The example column is one illustrative row.

ColumnWhat to writeExample
Raised onThe date the buyer first told you, by any routeDay 1
Customer and partBuyer, part number and pattern numberPump maker, casing, pattern 112
ProblemRejection, short supply, late dispatch or wrong papersRejection
Found whereIncoming inspection, after machining, at assembly or in the fieldAfter machining
QuantityPieces affected, out of the lot18 of 300
CauseThe defect and its root, in shop wordsShrinkage at the flange boss, riser too small
First replyWhen, and who answered the buyerDay 2, quality head, by phone
Written answerWhen the cause and action note went, and to whomDay 6, to the quality engineer, purchase copied
Change madeWhat is different on the floor nowRiser enlarged, first casting of each lot cut and checked
DebitValue of the debit note, and whether you accepted itAccepted after seeing the pieces
ClosedWhen the buyer confirmed it, or "open"After the next lot came through clean
Next scheduleDid the next release grow, hold or shrink?Held

The last column turns a quality log into a sales tool. Enough rows show which problems, answered which way, cost you volume.

Reading the register before the buyer does

Sort it by pattern, not by customer. When one pattern appears in three rows, the pattern or its method is the problem. Fix it before you quote that buyer anything new.

Give every row a written answer within a week of the complaint. A row still waiting after seven days goes to the owner's desk, whoever was handling it.

Before any review meeting or visit, print that customer's rows, closed ones included, and take them in. Go through them yourself before the buyer raises them: what happened, why, and what changed. A supplier that brings its own failures to the table turns the meeting from blame into evidence.

Close a buyer's open rows before you show the buyer the register, and do not use it to contest every debit.

For example: a Sangli foundry and a shrinking schedule

Imagine a grey iron foundry in Kupwad MIDC, Sangli, pouring pump casings for a pump maker in Pune. The details are illustrative.

Over two releases, the schedule for the main casing fell to about half. The owner assumed a rival had undercut the foundry and cut the rate by about 4 per cent. The buyer accepted it, and the quantity stayed where it was.

Then the owner built the register from that customer's debit notes and returned-casting challans. There were four rejections in a year. Three were on the same casing pattern, all shrinkage at the same boss, and each had been answered by sending replacement castings and nothing else. When the owner asked to see the buyer's notes, two read "repeat defect, no corrective action".

The foundry enlarged the riser on that pattern and began cutting the first casting of every lot. The owner sent the four rows, the cause and the change to the quality engineer and purchase, and asked for a review. There the owner walked through the rows before anyone raised them. Over the next releases the casing quantity climbed back to roughly three quarters of its old level, not all of it. The rate cut stayed, which was the price of guessing instead of looking.

A sheet or a CRM, and what neither can fix

A shared spreadsheet is enough if one person handles every complaint. A CRM, set up through CRM implementation and customisation, earns its place when several people raise complaints or the register should sit beside each customer's quotations.

The register will not save an account lost to a foundry with machining in-house, or a buyer cutting the supplier list for reasons of its own. And if the rows show your rejection rate is the real problem, the cure is method and metallurgy, not a better reply.

If the register shows that most rows came in the first lot of a new buyer, start with getting the first repeat order. Agreeing who answers what is the job of complaint and escalation management. See also casting and foundry.

Fill the first rows from your debit notes

Ask accounts for every debit note from your three largest buyers. Ask stores for every returned-casting challan. Enter each as a row and fill in what you can remember; the blank columns are the habits to fix first. If you want the register set up and the reply routine agreed with your team, tell us what you need.

Questions

Questions owners ask.

Should we accept every debit note for castings rejected after machining?
Not without seeing the pieces. Ask for the rejected castings back, or photographs and the inspection report, before accounts accepts the debit. Some defects are yours, such as blowholes and shrinkage. Others start in the buyer's own machining. Record the outcome in the register either way.
Who in the foundry should own the register?
One person who talks to both the shop floor and the buyers. In a small foundry that is the owner or the quality head. Supervisors add the cause and accounts adds the debit, but one person decides when a row is closed and who calls the buyer.
Can we ask a buyer for our vendor rating?
Yes. If the buyer keeps a rating for each supplier, ask for yours and what goes into it. Put each figure beside your own register rows. Where the buyer's numbers and yours disagree, you have something specific to raise at the next review instead of a general complaint about volumes.
