What this article covers
This guide turns an early sourcing request into an engineering-ready RFQ for TV structural parts. It focuses on the information that lets a manufacturer judge process fit, tooling needs, validation scope and production readiness.
- How to define the exact structural component and its assembly role.
- Which drawings, revisions and physical-sample details should be shared.
- How to describe interfaces, material, finish and tooling status.
- Why volume, lifecycle and timing belong in the same engineering conversation.
- What validation, packaging and destination requirements should be explicit.
- A minimum RFQ package that can start a useful feasibility review.
A useful RFQ does more than ask for a price. It gives the manufacturing team enough information to understand what the part is, how it fits into the television, which process is likely to make it, what tooling exists, what remains uncertain and what evidence will be required before production. The clearer those inputs are, the less time both sides spend correcting assumptions after quotation.
TV structural components are especially sensitive to incomplete RFQs because apparently similar products can have different panel modules, board layouts, speaker positions, ventilation, mounting interfaces, rear-cover concepts and tooling histories. A request that includes only screen size and annual quantity may be commercially convenient, but it is not yet an engineering definition.
The goal of this guide is not to make every buyer complete a perfect specification before contacting a supplier. Early projects are often incomplete. The goal is to make the uncertainty visible so the supplier can distinguish confirmed requirements from open engineering questions.
1. Define the exact component before discussing price
Start by naming the part and describing its role in the final assembly. The request may cover a stamped metal back plate, molded rear cover, rear housing, structural chassis, bezel, frame, speaker cover, stand-related component, tooling package or a combination of parts.
If the terminology is not standardized inside the buyer’s organization, connect the name to the drawing or physical function. The TV Back Plate, Back Cover, Rear Housing and Chassis guide explains why these terms should not be treated as universal synonyms.
A useful definition can include:
- internal part number or model reference;
- screen size and program name;
- whether the part is visible exterior, internal structure or both;
- whether the RFQ covers one part, multiple components or an assembled module;
- which surrounding parts are supplied by others;
- the intended manufacturing process if it is already fixed.
This first step prevents one of the most common sourcing errors: comparing quotations from suppliers that are actually quoting different scopes.
2. Share the latest drawing, revision and sample status
The manufacturer needs to know which geometry is authoritative. Provide the latest available 2D drawing, 3D model or physical sample status and identify the revision. If the drawing is preliminary, say so. If only a sample exists, say that too.
Revision control matters because tooling, samples and inspection records can quickly become disconnected when files change through email. A useful RFQ should state which revision is being quoted and which dimensions or interfaces are still open.
When sending files, consider including:
- 2D drawing with datums, critical dimensions and tolerances where defined;
- 3D model for geometry and interference review;
- assembly drawing showing the component in context;
- existing inspection report or sample issue list if one exists;
- photos only as supplementary context, not as a substitute for dimensional data;
- a note identifying any geometry expected to change before tooling freeze.
A product image can help orient the discussion, but it cannot establish material grade, thickness, hidden geometry, tolerances or revision status. Those details must come from controlled engineering information.
3. Call out the interfaces that can change tooling and fit
A structural part does not work in isolation. The RFQ should identify the interfaces that determine fit and assembly. For a TV rear structure, these can include the panel/module, main board, power board, speakers, connectors, cable routes, ventilation, stand, wall-mount pattern, decorative covers and surrounding bezels or housings.
Not every interface needs a long written explanation if it is already clear in the drawing. But the supplier should know which interfaces are functionally critical and which areas have flexibility. That distinction can affect feasibility, tool design and later change management.
If a mounting point is controlled by another supplier or a purchased module, identify that dependency. A local feature that looks easy to move in the structural drawing may actually be fixed by another system component.
For multi-part rear structures, define the responsibility boundary. Is the structural supplier only making a stamped plate, or also assembling molded covers, brackets or hardware? Quotation, inspection and packaging should all follow the same scope definition.
4. State material, thickness and finish—or state that they are not final
Material information can materially change the manufacturing route. For sheet-metal parts, identify the specified grade and thickness where they are known. For molded parts, provide the resin specification or approved material family. For both, include finish, appearance or coating requirements that influence processing and inspection.
If the project is still evaluating materials, do not fill the RFQ with a guessed value. State that the material is open and describe the performance or appearance requirement that the team is trying to achieve. The supplier can then treat material selection as an engineering question rather than as a frozen specification.
For a TV metal back plate, buyers may want to clarify:
- sheet-metal grade and thickness;
- coating or surface treatment;
- visible vs non-visible surface areas;
- corrosion or handling expectations where applicable;
- areas sensitive to flatness, forming marks or appearance;
- any customer-specific material documentation requirement.
KINGSUN’s current product pages intentionally avoid assigning a universal SGCC thickness to a product based only on imagery. Where worksheet values are verified for named models, they are presented as model-specific references; final project material still follows the approved drawing.
5. Explain the existing tooling situation early
Tooling status can change both quotation and schedule. Tell the supplier whether the project is expected to use a current platform, transfer an existing tool, adapt a tool or develop dedicated tooling.
If a tool already exists, useful information includes ownership, physical location, last produced revision, maintenance condition, available design records and the machine or press on which it previously ran. The supplier may need to inspect the tool before confirming whether transfer or adaptation is realistic.
If the project hopes to use a shared platform, identify which interfaces must remain common and which are allowed to change. “Same screen size” is not enough to prove tool compatibility. The Shared Tooling or Custom Mold guide provides a fuller decision framework.
If new tooling is expected, state whether the RFQ should include tooling development, trial samples, modification cycles, inspection support and production preparation. Tool price without scope is difficult to compare meaningfully.
6. Provide realistic volume, lifecycle and timing inputs
Volume helps the supplier match the project to the manufacturing route and production resources. Exact forecasts are not always available, especially early in sourcing, so a reasonable range is more useful than no information.
Separate the different stages:
- engineering / trial sample quantity;
- pilot or validation quantity;
- expected monthly or annual production range;
- expected product lifecycle;
- planned ramp date and any phased regional launch.
Timing should also distinguish the dates that matter. “Need ASAP” is not a schedule. Buyers should identify when drawing freeze is expected, when samples are needed, when validation should finish and when production is expected to begin.
This allows tooling, material preparation, equipment matching, sampling and packaging planning to be sequenced against the actual project instead of against one ambiguous delivery date.
7. Define what must be proven before production approval
An RFQ should identify known validation requirements even when the full control plan is not finished. The supplier needs to understand what evidence will be expected from samples and what characteristics matter most to the final assembly.
Depending on the component and project, validation may include:
- dimensional inspection and critical datum relationships;
- appearance acceptance for visible surfaces;
- assembly-fit checks with surrounding components;
- material or coating confirmation;
- tooling-trial issue tracking and revision closure;
- packaging and handling review;
- customer-specific documentation that has been explicitly requested.
Do not assume that a supplier automatically knows every brand-specific or destination-specific validation requirement. If a required standard, drawing note or customer procedure exists, include it in the sourcing package or identify it as a pending input.
8. Packaging, logistics and destination can affect the part requirement
Structural components can be large relative to their mass and can be sensitive to bending, scratching, deformation or contamination. Packaging therefore belongs in the project discussion rather than being treated as a final shipping detail.
The RFQ should indicate whether the part will move to a nearby assembly line, travel by long-distance truck, enter export logistics or require returnable packaging. The buyer should also state whether packaging design is included in supplier scope and whether there are restrictions on pallet size, stacking, labeling or handling.
Destination information is useful when it changes documentation, packaging or logistics assumptions. But the manufacturer should not invent regulatory requirements from a country name alone. The buyer or responsible compliance team should identify the standards and destination-specific requirements that apply to the program.
9. Make open issues and change control visible
Many sourcing problems begin when one side thinks the design is frozen and the other side still expects change. An effective RFQ identifies open items and assigns a status to them.
A short assumption sheet can be valuable. It might list material as “confirmed,” wall-mount pattern as “confirmed by customer drawing,” speaker opening as “under review,” and coating as “to be nominated before sample approval.” That level of visibility helps the supplier quote with the correct level of confidence.
When revisions are issued, keep the commercial and engineering records synchronized. The supplier should know whether a new revision changes only annotation or whether it affects material, geometry, tooling or inspection scope. Not every revision requires a new quotation, but every material change should be visible.
Requirement · Current value/revision · Status (confirmed/open) · Owner / expected decision date.
This simple structure often prevents more confusion than a long email thread because it separates facts from pending decisions.
10. A minimum useful TV structural-component RFQ package
Not every project begins with complete data. If the program is early, the following minimum package can still support a useful first feasibility review:
| Input | Minimum useful information | Why it matters |
|---|---|---|
| Part definition | Part type, screen size, model/program context, scope boundary | Prevents suppliers from quoting different components |
| Geometry | Latest drawing revision or physical-sample status | Provides the basis for process and tooling feasibility |
| Interfaces | Critical mounting/opening/assembly relationships | Shows which geometry cannot be changed freely |
| Material | Specified grade/resin or an explicit “open” status | Affects process, tool design and validation |
| Tooling | Existing/shared/transfer/new-tool expectation | Changes engineering scope, schedule and quotation structure |
| Volume | Sample, pilot and forecast range | Supports equipment, tooling and capacity planning |
| Timing | Sample need date and target production timing | Lets engineering and manufacturing tasks be sequenced |
| Validation | Known dimensional, appearance, fit and documentation requirements | Defines what “approved” must mean |
If only half of these items are known, the RFQ can still move forward as long as the unknown half is clearly marked. A transparent incomplete requirement is easier to manage than a complete-looking requirement built on assumptions.
11. Common RFQ patterns that create avoidable rework
Several patterns repeatedly reduce quotation quality:
- Screen size only: assumes all rear structures for one screen size are interchangeable.
- Image only: asks the supplier to infer dimensions, material and hidden interfaces from appearance.
- Price first, drawing later: creates a number before the manufacturing scope is understood.
- Annual volume without sample timing: does not show when tooling and validation must be ready.
- Existing tool with no tool information: assumes an asset is transferable before ownership and condition are known.
- “Standard quality”: leaves acceptance criteria undefined.
- Multiple drawing revisions in email: makes it unclear which file the quotation actually uses.
A stronger RFQ does not need to be longer for its own sake. It needs to make the important variables visible.
12. How KINGSUN uses the RFQ to identify a manufacturing path
KINGSUN’s current website connects TV structural products with metal stamping, mold manufacturing, injection molding and an OEM & ODM process. A clear RFQ helps determine which of those capabilities are relevant to the specific part.
For example, a stamped back plate with a stable drawing may move quickly into material, forming and tooling review. A molded rear housing may require a different set of questions around resin, cosmetic surfaces and mold structure. A project with an existing tool may first require tool inspection. A project with unresolved part terminology may need the scope aligned before quotation.
The website RFQ form is intended to collect project context. Drawings and project files can be sent through the sales email shown on the Contact / RFQ page. If the requirement is not yet complete, identify what is known and what remains open; the first response should help organize the engineering conversation rather than pretend that every decision is already fixed.
