Parts go to the finisher whose process, bath and test results the buyer can check.

A purchase engineer at a pump maker has a drawing with a note on it: zinc plate, or anodise, or harden to a stated range. The usual shop is full. The engineer searches the process name, opens a few websites and an IndiaMART listing, and looks for the same things: is this process done here, on which metals and part sizes, and what record comes back with the lot. A page that answers those questions gets a trial lot. A rate and a phone number do not.

In one paragraph

Metal finishing and surface treatment covers the job-work shops that coat, plate, treat, harden or polish metal parts that belong to someone else. GullySales looks at how a fabricator or purchase engineer finds your works, what you show about the process and the result, and how a trial lot becomes a repeat order.

The five trades on this page do different things to the part. One lays on a coat, one deposits a layer, one changes the skin, one changes the grain inside, one works the surface by hand and machine. What they share is that the part is the customer's, sent in a batch against a drawing, a sample or a specification. They share a first lot that is judged before the second one comes, a rate quoted per kilogram, per square foot or per piece that makes unlike shops look alike, and an oven, tank, furnace or bench that earns only when it is loaded.

5 kinds of business

Each kind of business in metal finishing & surface treatment sells a little differently.

Open the page closest to yours for how its buyers choose and what we would fix first.

Powder coating companies

Callers ask the rate per square foot and move on. Oven size, shade standards and photographs of finished work give fabricators more to go on, and a list of regular buyers helps in the weeks the oven runs light.

Electroplating companies

Buyers treat plating as a commodity priced per kilogram. A purchase engineer needs the coatings you offer and your process records to approve you, and quality checklists answered from a ready pack.

Read the page for electroplating companies

Surface treatment companies

Design engineers search by process name, such as anodising or passivation. The work is a page for each process, the alloys and sizes you can take, and documents ready for approval trials.

Heat treatment companies

A metallurgist asks about hardness, testing and records first. Furnace types, test reports and batch records shown on the page answer that, and move the talk away from price per kilogram.

Metal finishing companies

A surface judged by eye and hand, and rejected work arrives from other shops. Photographs of before and after, and a finish standard agreed with the buyer, set you apart from a rate per piece.

What they share

What usually goes wrong across metal finishing & surface treatment.

Whichever of these you run, you will probably recognise most of them.

“Buyers compare our rate and nothing else”
A caller asks the price per kilogram, per square foot or per piece, hears ours and rings the next shop. Our process, our checks and our rejection record are not in front of the buyer, so a lower rate wins.
“Enquiries arrive without the detail we need to quote”
A grade and a weight, a photograph of a part, or a call saying we need it finished. Nobody asks for the drawing, the quantity or the standard at the first reply, and the lead goes cold while we chase it.
“The first lot is done and then nobody follows up”
A trial lot goes out, the buyer inspects it, and we wait. We do not know whether it passed, who approved it or when the next lot is due, so repeat orders depend on the buyer remembering us.
“Our process records are rebuilt for every approval”
Test reports, batch sheets, thickness or hardness readings and process notes sit in files and in the supervisor's head. Each new vendor questionnaire means gathering them again, and the buyer waits.
“Our capacity is full one week and idle the next”
A large order from one customer fills the line, and then a gap follows. Without a list of past buyers and what they sent, nobody calls to fill the quiet days.
“Our best work is on a phone and cannot be shown”
The cleanest finish, the toughest part or the largest batch is the proof a new buyer wants. Customers do not allow their names to be used, and so we have shown nothing at all.

Where to start

What to fix first in metal finishing & surface treatment.

In the order we would look at them. Your own enquiry records may change the order, and we would say so.

Give each process its own page: what it does to the part, the metals and part sizes you take, the standards you work to and what record comes back with the lot.
Ask for the drawing or sample, the quantity, the material and the standard in the first reply to every enquiry, and keep one list of enquiries so that none goes quiet.
Quote with the basis stated, whether per kilogram, per square foot or per piece, and say what the rate includes, such as masking, racking, testing and packing.
Keep the inspection and test records of each lot in a ready pack that can go to a buyer's vendor approval without being rebuilt.
After a trial lot goes out, record who is to approve it and ask them for the result, so that a pass becomes a repeat order and a reject is learned from.
Photograph finished parts with permission, and where the customer cannot be named, describe the work by part type and industry.

FAQ

Tell us what you need

Why do buyers treat our work as a rate per kilogram or per piece?

Because the rate is the only thing they can compare. Put the process, the part sizes you take, the checks you run and the records you send on the page, and the buyer has something to weigh against the rate.

What should a quotation for job work state?

The unit of the rate, the quantity it applies to, what is included, such as masking, racking, testing and packing, and which costs are one-off. Written the same way each time, two quotes can be compared fairly.

How do we show our work if customers do not allow their names to be used?

Show the equipment, the checks and the records, and describe jobs by part type and industry. Ask permission before naming anyone, and describe the work in general terms if they say no.

What do we do when a trial lot goes quiet?

Note the approver's name when the lot leaves, and ask for the inspection result by phone or WhatsApp. A buyer who has not replied may be waiting on someone else, and the question tells you who.

Does a small shop with one oven, one tank or one furnace need a website?

Yes. A buyer looking for a process in a particular city searches before ringing anyone, and a short page for each process you run is what they find. A small shop can say plainly what it does well.

What can GullySales do for a finishing or treatment works?

We read your requirements brief, talk to you, and then put the scope, fee and term in writing. The work starts from your enquiries, your process records and your idle days, and results are reported against a baseline recorded first.

How much does it cost?

There is no price list, because the work differs by business. The fee is scoped after we have read your brief and spoken to you, and put in writing before anything starts, split into our time, your media spend and production.

How long is the contract?

The term is agreed in writing after we have spoken, along with the fee and the reporting. It is never a default twelve months, and renewal is decided on the numbers against the baseline recorded at the start.

How soon will we see results?

It depends on what is being changed and how many of the people who matter see it. After we have read your brief and spoken to you, we say what we would expect to move first and how it will be measured against the baseline. Nothing here is guaranteed.

Who will actually do the work?

The person you speak to before anything starts. We work from one office in Nagarbhavi, Bengaluru, with no account managers in between.
