Use the end-use application, part family, forming route, material and acceptance basis to decide whether a new OEM forging project belongs in the HULK Metal RFQ process.
OEM forging scope - pre-RFQ screening
Quote, review or stop: the five-field forging scope gate
Which industries do you NOT serve?
The short answer: some projects must stop before quotation
NO-GO UNTIL REVIEWEDHULK Metal does not quote new OEM forging programmes for automotive, chemical including petrochemical and refining, medical or high-precision industry applications. Gears, shafts, aluminium forging, cold forging, rolled ring forging, forged wheels, grade 4340, titanium forging and H13/D2 tool-steel forgings are also outside the established scope.
The word “industry” matters, but it does not decide the case by itself. A buyer can name an allowed industry and still send a forbidden part family, material or process. The opposite also happens: a suitable forged part can be attached to an excluded end-use application.
Scope rule: the project must pass the end-use application, part family, forming route, material grade and acceptance basis together. A pass on one line does not overrule a stop on another.
- StopAny excluded industry, part family, forming process or material is present.
- ReviewThe application class or production route is unclear and needs a written scope decision.
- ContinueThe five fields meet the established OEM scope, subject to drawing-based feasibility and acceptance review.
The forging scope gate at a glance
The fastest screening method is to compare the RFQ against four separate lines. Do not use a legacy page or a general forging definition as proof that a new project is in scope.
| Gate | Continue to drawing-based review | Stop before quotation |
|---|---|---|
| End-use application | Mining, agriculture, oil and gas upstream or pipeline, valve, wind energy, construction and related industrial hardware | Automotive, chemical including petrochemical and refining, medical, or high-precision industry applications |
| Part family | Flanges, forged rings as OEM parts, wear parts, valve parts, wind flanges and hubs, couplings and hubs, upset parts, brackets, pulleys and sheaves | Gears, shafts, forged wheels, H13/D2 tool-steel forgings; lifting hooks are not a lead product for new projects |
| Forming route | Hot die forging and hot upsetting, quoted to the buyer's drawing | Cold forging, cold heading and rolled ring forging |
| Material | Carbon steel, alloy steel and stainless steel, with the exact grade checked against the drawing | Aluminium forging, titanium forging, grade 4340 and its equivalent designations |
| Commercial model | OEM custom parts to a controlled drawing | Stock-size selection or a standard forged-parts catalogue |
This is why “Can you forge this drawing?” is incomplete. The same outline can belong to an allowed mining spare or an excluded automotive programme. The RFQ has to identify both.
Applications that remain in the established OEM scope
Several application lanes are explicitly covered. They still require feasibility review, drawing agreement and acceptance planning; inclusion in this list is not a blanket approval of every material or geometry.
- Field equipmentMining equipment spare parts, agricultural wear parts and construction hardware.
- Energy and flowOil and gas upstream or pipeline parts, valve forgings, wind flanges and hubs, and forged rings as OEM parts.
- Mechanical hardwareCouplings and hubs, upset forged parts, brackets, pulleys, sheaves and non-hook hand-tool components.
An oil and gas request illustrates the boundary clearly. Upstream drilling or pipeline work belongs in the stated scope; refining and petrochemical processing do not. The buyer should state the service environment, not only the broad industry label.
Large-diameter flange quantities are confirmed per drawing. A familiar flange drawing does not create a standard catalogue, fixed MOQ or assumed delivery slot. The written offer must connect the exact part to the exact commercial conditions.
What if the application is allowed but its downstream market is not?
State the final market. Upstream oil and gas belongs in scope; refinery and petrochemical processing do not. A similar shape does not move the application across that boundary.
Part, material and process rules override a matching industry
A buyer may work in mining, wind energy or construction and still request an excluded part. The negative scope is not cancelled by the end industry. The table below shows the most consequential cases.
| Request | Why it stops | Correct next action |
|---|---|---|
| Gears or shafts | These part families are outside the established capability list, including gear blanks and crankshafts. | Do not ask for a tolerance, MOQ or lead-time review as if the family were available. |
| Cold forging or cold heading | HULK Metal's confirmed forming scope is hot die forging and hot upsetting, not cold processing. | A hot route is a different engineering decision; do not relabel the same cold process. |
| Rolled ring forging | Forged rings are available as OEM parts to drawing; ring rolling is a separate excluded process. | Send the forged-ring drawing and identify the required route, not only the word “ring”. |
| Grade 4340 | 4340 and its equivalent designations are outside the available material list. | Send the actual grade for review; do not substitute 4140 unless the drawing permits it. |
| Aluminium, titanium or H13/D2 tool steel | These are excluded materials or forging applications in the established scope. | Stop before requesting tooling or a production plan. |
| Lifting hook programme | Hook families are not a lead product line for new projects. | Do not use another hand-tool or hardware request to imply a hook capability. |
Do not reword the request to pass the gate. Changing “cold forging” to “forging” does not change the process route. Changing a banned steel grade to a vaguer steel description does not make it available. The latest controlled drawing and material statement still govern.
- Do not infer scope from an industry nameThe part family and process still have to pass.
- Do not infer scope from a legacy pageAn existing page does not create a new-project capability.
- Do not infer scope from a quote requestAsking for a price does not make an excluded route available.
Run a red-flag check before sending the drawing
Search the enquiry for a restricted industry, part family, process or grade. If one appears, resolve that field in writing before asking for tooling, MOQ or delivery. A short “not sure” response is safer than assigning an allowed label that the application does not support.
Five fields to send before a quotation can begin
A useful scope review does not begin with price. It begins with enough information to decide whether HULK Metal should quote the project and which first-party owner page the buyer should read next.
- End-use application. State where the part operates and which industry receives it. Use “oil and gas upstream” or “refinery” precisely; the two are not in the same scope.
- Part family. Name the physical part and its function. A drawing title alone may not show whether the item is a gear, shaft, coupling, bracket, flange or forged ring.
- Forming route. Confirm hot die forging or hot upsetting where known. Do not use a generic “forging” label to hide a cold or ring-rolling request.
- Material grade. Give the grade and material condition from the controlled drawing. If the buyer has not fixed the grade, identify that as an open decision.
- Drawing revision and acceptance basis. Send the finished-part drawing, forging drawing or sample basis, and identify dimensional, material, hardness, tensile and NDT requirements that release the batch.
Open the checklist below to make the screening explicit. These are native disclosure controls; all rules remain readable without JavaScript.
Pre-RFQ scope checklist
1. Industry statement: compare the application with automotive, chemical including petrochemical and refining, medical and high-precision industry exclusions.
2. Part-family statement: compare the item with the gear, shaft, forged-wheel and hook boundaries.
3. Process statement: confirm hot die forging or hot upsetting and rule out cold forging or ring rolling.
4. Material statement: identify the exact grade and check aluminium, titanium and 4340 exclusions.
5. Acceptance statement: attach the drawing revision and the inspection methods that will release the order.
A quotation is not a valid comparison basis if it omits one of those fields. That rule protects both sides: the buyer compares like with like, and the supplier does not build a price around an unstated excluded application.
What to send after the project passes the gate
For an allowed application, the next step is the established OEM forging RFQ route. HULK Metal supplies custom hot die forged parts to the buyer's drawing and does not maintain a stock-size catalogue. The OEM forging process page describes the product route; this FAQ only settles whether a new project belongs in it.
Send the drawing or sample information together with material, quantity, delivery destination and required inspection records. The live FAQ on information for an inquiry provides the compact input list. For material classification, use the existing materials FAQ and keep the final grade tied to the drawing.
Tolerances, machining allowances, hardness bands, case depths, unit weights, MOQ, tooling cost and timing are not fixed on this page. They are per drawing or Contact us for details. That wording is not a delay; it prevents a generic catalogue value from being mistaken for a commitment on a custom part.
What this page does not confirm
Several details remain outside a scope FAQ. HULK Metal uses induction heating and multiple forging presses, performs in-house inspection and arranges heat treatment through an audited partner. The company states ISO 9001 only; this page does not add a certificate, standard, NDT level or heat-treatment furnace claim.
An excluded item should not be placed into the RFQ as a test of whether the rule can be changed. A capability that does not appear in the confirmed list requires a written scope decision before price, tooling, MOQ or delivery planning. An old page, a competitor claim or an abandoned enquiry does not create that decision.
Can an old HULK Metal page confirm a new capability?
No. Use the current written scope and the controlled order requirement. A legacy page may help a buyer understand a historical offer, but it does not override the current scope or turn an excluded part, material or market into a new-project approval.
Five fields first, then the drawing. Send the application, part family, forming route, material grade and drawing revision. A clear stop now prevents an unsuitable quotation, tooling deposit or acceptance dispute later.
