Surface treatment companies · Manufacturing

Be the specialist a design engineer finds when the drawing says anodise or passivate.

A design engineer at an electronics enclosure maker has finished a drawing with a note that reads hard anodise, black, and does not know who in the city does it. The engineer searches the process name, calls two shops and sends a drawing to the one that asks sensible questions about alloy and thickness.

Scope, fee, reporting and term are agreed in writing after we have read your brief and spoken to you.

In one paragraph

Surface treatment companies change the surface of a metal part through processes such as anodising, phosphating, passivation, black oxide and pickling so it resists corrosion, wear or heat. Marketing makes you the specialist that engineers search for by process name. Sales turns a drawing note into a trial lot, a documented process and, once approved, repeat lots.

Surface treatment work is specified, not shopped for. The process name sits in the drawing note, so the buyer starts from a specific method and looks for a shop that does that method well, with the paperwork their customer will ask for. A page for each process, with the alloys, sizes and checks stated plainly, gives the engineer a shop to call.

How buyers decide

How surface treatment companies are chosen.

Buyers are design engineers, quality heads and purchase managers in electronics, aerospace-linked, defence-linked, auto, tooling and consumer product firms. They search for the process by name along with a location. They then check which alloys you treat, which size range your tanks take, the thickness and colour options and whether you can supply a test report.

Some buyers send a trial lot to see consistency before a drawing is released for supply. They look at dimension change after treatment, uniform colour, absence of staining and packing quality. Larger firms ask for process records, customer approvals you already hold and traceability of lots.

Once a surface treater is approved for a part family, the engineer has little reason to look elsewhere for the next part until a quality problem or a missed schedule.

The problem

What usually goes wrong for surface treatment companies.

What owners tell us on the first call, in their words.

  • “We do many processes but the website lists them as one line”

    Anodising, phosphating, passivation and black oxide are all described as surface solutions, so a search for any of them misses us.

  • “Engineers cannot tell what alloys and sizes we can take”

    Tank size, alloy limits and thickness ranges are in our heads, so every enquiry becomes a call.

  • “We are one of many with a tank and a price”

    Buyers see a list of surface treaters and compare only on rate per piece.

  • “Approval trials go silent”

    After sending a sample lot, we hear nothing while the engineer waits for customer clearance.

  • “Quality documents are rebuilt each time”

    Process steps, test records and certificates of treatment are assembled for each new buyer.

  • “We cannot show work for confidential sectors”

    Our best parts are for defence-linked and electronics clients who do not allow names or photographs.

What we do

What we do for surface treatment companies.

Everything included for surface treatment companies.

  1. A page for each process

    One page each for anodising, phosphating, black oxide, passivation, pickling and conversion coating, with alloys, size range, thickness and colour options clearly listed.

  2. A capability sheet by alloy and size

    A single sheet that lists the alloys, tank sizes, maximum part lengths, finishes and test checks you can deliver.

  3. Process and certificate pack

    A pack with your process flow, the checks and records you keep, and a sample certificate of treatment, prepared with your quality person.

  4. Trial lot tracker

    A record of each sample lot with the engineer, part, process and the customer clearance it is waiting on.

  5. Anonymised work write-ups

    Descriptions of part families such as enclosure panels, camera housings or tool components, giving the problem and the process, without names or photographs that would breach confidentiality.

  6. Enquiry intake form

    A short form asking for alloy, process, thickness, colour, size and quantity, linked to your WhatsApp.

How the result is measured

  • Enquiries by source and process
  • Enquiries that gave alloy and size
  • Trial lots started against regular orders won
  • Approvals in progress
  • Repeat orders from approved parts
  • Treatment certificates issued with lots

Recorded as a baseline before work starts, so every later report has an honest comparison.

Worth a page and a campaign of their own

Hard and decorative anodising · Phosphating and black oxide for steel · Passivation of stainless steel parts · Chemical conversion coatings · Pickling and descaling · Rust-preventive oiling for storage and transport · Process records and treatment certificates · Trial lots for approval · Handling and packing of finished parts

Priority campaigns

Campaigns for what surface treatment companies most want to sell.

Each one planned around when your buyers decide, and measured against the baseline.

  • Process-name search campaign

    Search ads and pages for the specific processes you run, such as hard anodising or stainless passivation, targeted at your region.

  • Electronics and enclosure maker outreach

    A note and capability sheet to makers of electronic housings and heat sinks about anodising options and colour consistency.

  • Stainless equipment passivation campaign

    Outreach to food, dairy and pharma equipment fabricators about passivation and pickling after welding.

  • Fastener and hardware black oxide campaign

    A page and message for fastener and tool makers about black oxide and phosphating for steel parts.

  • Approved-vendor record update

    A refreshed set of process records and treatment certificates for customers who hold you on an approved vendor list.

Beyond search

Where we reach buyers of surface treatment companies, beyond Google.

Search matters, but it is rarely the only way this industry's buyers find a supplier.

  • Design and manufacturing engineers

    The engineer who writes the drawing note. Makers of enclosures, instruments, tools and components near you are approached with a page named for the process on that note.

  • Stainless and process equipment fabricators

    Weld seams on stainless tanks and pipework discolour and need pickling and passivation before the equipment ships. That is the one-line pitch to the fabrication head.

  • Fastener, tool and hardware makers

    Steel parts leave the machine bare and rust in transit. Black oxide, phosphate and an oil film are the answers a tool or fastener maker asks about.

  • Machine shops

    A job-work machine shop that sends aluminium and steel parts out for different processes would rather deal with one source for both.

  • Electronics and instrument firms

    Anodised housings and front panels must match in colour from one batch to the next, and the buyer checks sample against sample.

Who it is for

This is written for these surface treatment companies.

  • Anodising shops for aluminium parts, hard and decorative
  • Phosphating and black oxide shops for steel and fasteners
  • Passivation and pickling shops for stainless steel
  • Chemical conversion coating on aluminium
  • Anti-rust and oil coating treatment for steel parts
  • PVD and vacuum coating studios
  • Descaling and rust removal units for fabricated and cast parts
  • In-house surface treatment units that take outside work

Not for

It is not the right fit if.

  • You want a guaranteed Google ranking or a guaranteed number of leads. Nobody honest can promise either.
  • You need enquiries by next week and have nobody to answer them.
  • You want posts and reach reported, not enquiries and orders.

How it works

From your first message to the first report.

No open-ended retainer. Every step gives you something in writing.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

How the work runs for surface treatment companies

  1. 1

    Read old drawing notes and open approvals

    Past drawing notes and approvals show which processes buyers name most and which approvals are still open.

  2. 2

    Document the capability

    A sheet by alloy, size and process, and a process and certificate pack.

  3. 3

    Write a page for each process

    A page for each process, written with your technical person and checked by them.

  4. 4

    Reach the engineers

    Outreach to design and quality teams, with search ads on process names.

  5. 5

    Track trial lots and refresh vendor records

    A sample-lot tracker, updated vendor records and a referral ask for approved buyers.

FAQ

Questions surface treatment companies ask before they call.

Not here? More answers, or ask on WhatsApp.

We run many processes. Should each have its own page?
Yes. Buyers search by process name, so a separate page for anodising, phosphating, passivation and the others matches how they look. Each page stays distinct by alloy, size and use.
Can you write about technical specifications?
Only what your team confirms. We describe the process and the checks you run. We do not state coating life or performance figures that you cannot back with your own test reports.
How do we show work we cannot name?
By part family, process and problem, with no client name, drawing or photograph that would breach confidentiality. A name is used only with written permission.
Is advertising worth it for a specialist process?
Search ads on a specific process name suit it, because the buyer already knows the process they want. Repeat work depends on the relationship with the engineer.
Can you help with customer approvals?
We help you prepare the documents and find the right people to send them to. Approvals are your customer's decision, and we cannot promise one.
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?
Fixes to reply time, follow-up and your Google Business Profile are the quickest to show, because the enquiries already exist. Ads can follow soon after follow-up is in place. SEO and content take longer. How long each takes depends on your business, and we tell you which applies to you after we have spoken. 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.
What do you need from us?
To start, last month's enquiries in any format and time with whoever handles them. After that, access to the accounts the work touches, such as the website, Google Business Profile or CRM.
