Manufacturing · Casting & Foundry
Buyers think of us as a small-parts shop, but we cast alloys most foundries will not touch.
Investment casting is chosen when a part is too intricate to machine and too small or detailed for sand. The buyer is usually an engineer who has a complex drawing and a limited quantity. They want to know whether the process can hold the shape and which alloys the foundry pours.
Scope, fee, reporting and term are agreed in writing after we have read your brief and spoken to you.
In one paragraph
Investment casting, also called lost-wax casting, builds a ceramic shell around a wax pattern, melts the wax out and pours metal into the cavity to make small, complex parts with a fine surface. GullySales helps investment casters explain their alloy range, part size and finish to buyers in pumps, valves, medical, firearms and general engineering.
That is a narrow question, and a general metalworking website does not answer it. The pages below the drawing stage matter: alloy list, size range, finish and what is done after casting.

Who it is for
This is written for you if investment casting is what you make or sell.
- Lost-wax foundries pouring stainless, carbon, alloy steels and non-ferrous metals
- Units that make wax patterns in-house and also build wax tools
- Shops that serve valve, pump, textile machinery and instrument buyers
- Foundries that machine and heat-treat the casting before dispatch
Not for
It is not the right fit if.
- A shop that wants to compete on very large parts, which this process does not suit
- A foundry that has not yet produced a stable shell process and cannot hold its yield
How buyers choose
What decides the sale of investment casting.
Part complexity and surface finish
The engineer decides on investment casting because machining or fabrication would cost more. They want to see surface finish and detail on actual castings.
Alloy range
Stainless grades, tool steels, cobalt and nickel alloys, or non-ferrous metals. The shop that lists what it has poured is shortlisted for matching drawings.
Wax tool cost and quantity
The wax pattern tool is a one-time cost that must be spread over the run. Buyers ask for it separately and compare with other shops.
Dimensional reports and first-article sample
The buyer measures the first lot against the drawing. A foundry that offers dimensional reports at the first lot starts ahead.
Where orders are lost
What usually goes wrong when you sell investment casting.
In the words owners use on the first call.
“People send drawings for parts we should not take”
Parts too big or tolerances too tight for the process come in, and the foundry spends time quoting or declining. A clear range page cuts these.
“We lose to a Chinese or Taiwanese quote on rate”
Rate is compared with no regard to lead time, tooling risk and communication. The foundry has never set out what a local supplier gives.
“Buyers do not know we can do that alloy”
The shop pours several alloys, but its website says stainless and carbon steel. Searches for a particular grade never reach it.
The scope
The work we would propose for investment casting.
Measured on qualified enquiries, quotation requests, follow-up on each quotation, trial orders won and repeat orders. Anything here that needs a platform, directory or tool we have not used with you is confirmed with you before it goes in the scope.
- An alloy and size range pageOne page per alloy family, with weight range, section thickness and example parts, so a search for a grade lands on you.
- Sample gallery with specification notesPhotographs of castings with alloy, weight and finish noted beside each, as an engineer would want them.
- Prospecting among small-batch OEMsInstrument makers, valve makers, textile and packaging machine builders who buy small complex castings.
- Tool-cost and quantity explanationA quotation that separates wax tool cost from piece price, and a follow-up call to discuss quantity.
A local-supply case against imported quotes
A short comparison sheet on lead time, sampling, communication and changes to the drawing, for buyers weighing an import.
What we do
What you get for investment casting.
Each deliverable and what it is there to change.
An alloy-by-alloy range sheet
Grades, weight range and parts cast, so engineers searching a grade find you.
A casting gallery with specifications
Photos with alloy, weight, finish and secondary operations noted.
A quotation format that splits tool and piece cost
Makes the quotation easy to compare and easier to approve.
A local-supply comparison sheet
What a buyer gains from a nearby foundry, in plain terms.
How the result is measured
- Qualified drawings received
- Drawings declined as out of range
- Quotations followed up
- Wax tool approvals and trial orders
- Repeat orders after first lot
- Searches by alloy that reached the pages
Recorded as a baseline before work starts, so every later report has an honest comparison.
How it works
From your first message to the first report.
No open-ended retainer. Every step gives you something in writing.
First
Your brief
You tell us what you need in a few short steps: your business, what you want, where enquiries come from and how they are handled.
After the brief
A conversation and a written scope
We read it, then talk with whoever handles your enquiries. If you want our help, the scope, the fee and the reporting come in writing, and nothing starts before you have read them.
Before work starts
Baseline recorded
The numbers this work is meant to move, such as enquiries, quotations, orders, visits or renewals, written down so every later report has an honest comparison.
After the baseline
The first fix goes live
The fix we agreed to start with is put in place and measured against the baseline, whether that is a reply, a follow-up, a page, a listing or the handover between marketing and sales.
As agreed
Report against the baseline
What moved, what did not, and what changes next, in plain words. How often you get it is set in writing before work starts.
At renewal
Renew on the numbers
The term ends and you decide whether to continue from the results. The length is agreed in writing before anything starts.
What we need from you
What to have ready before we talk.
None of it has to be tidy. We read what you have.
- Alloys poured and any alloys you could pour
- Smallest and largest castings, and weight range
- Photographs of finished castings
- Recent quotations that were lost, and the reason if known
- Machining, heat treatment and finishing you offer
Export and new regions
Selling investment casting beyond your home market.
Where you sell decides standards, documents, payment terms and freight. We work from Bengaluru and have no overseas office, so for a new region we start from your own enquiries, your existing buyers and the directories you already use.
Buyers in Europe and North America
Small-batch OEMs there often source investment castings through agents. Your current export enquiries show whether you are in that channel.
Dimensional and material reports
Overseas buyers ask for a dimensional report and a material certificate with the first lot. Say what you issue, with the equipment behind it.
Samples and wax-tool payment
Sample freight is small, but the tool payment needs agreeing first. Bring it into the first reply.

Why us
Why owners pick GullySales over an agency.
Marketing and sales, as one job
