OEM manufacturing · Artwork & specifications
An OEM supplier for your custom enamel pins.
Bring your existing design into a clearly defined manufacturing brief. For business enamel pin orders, the artwork, construction, design versions and supplied arrangement need to be considered together.
Prepare your OEM brief
Green Frog Supply supports the discussion from your available artwork through manufacturing, review and packing with our own factory in Hangzhou, China. Keychains, medals and enamel charms can also be discussed; the shield pin shown is an illustrative custom concept.
Send the design and its context.
A useful brief describes the product and the order, as well as the image. Mark estimated or unresolved details as provisional.
Design
Share the artwork or clearest available reference. Identify the wording, shape or identity details that your organisation needs to retain, and tell us which material is available for further work.
Product
Describe the intended use, size direction, enamel surface, visible metal, reverse and fittings. If a decision remains open, explain the effect or function you are trying to achieve.
Order
List quantities by design or version, target market, required presentation and target timing. Clarify whether you mean individual pieces, components or complete sets.

An image can introduce the project without being a complete manufacturing instruction. We discuss the suitability of the material and any additional information required before arrangements are confirmed.
Review the detail at product size.
A larger drawing can conceal decisions that become important in a small metal product. Review the feature in the context of the complete pin.

Lettering & fine lines
Identify the detail that must remain recognisable. Size, spacing and the way a feature is represented may need to be discussed together.
Metal & colour boundaries
Consider the shape of the colour areas and the metal divisions between them. A proposed adjustment should preserve the design intention, rather than simply remove detail.
Outline & reverse
Look at edges and fixing positions alongside the front. A clear face design does not settle the reverse, attachment or supplied structure.

Record the feature, the intended appearance and the question to resolve. No single minimum line width or detail limit is assumed for every product.
Define the complete supplied product.
A specification connects the artwork to an object and the way it will arrive. Keep the front, reverse, fitting and presentation in the same discussion.

Shape & size direction
Name the design version and intended dimensions or size direction. Identify details that matter to the business use.
Enamel & visible metal
Discuss the desired recessed or more level surface together with colour areas, metal boundaries and the visible finish.
Reverse & fitting
Specify the relevant fixing, its position and the assembled or component scope. Confirm what remains with your team.
Presentation & protection
Explain any backing-card, sleeve, set or outer-packing requirements. Identify the counting unit before quantities are treated as an agreed scope.
These are decisions to define, rather than a list of standard configurations promised for every order. The production and quality guide explains the relationship between surface, structure and review.
Read the production & quality guideKeep versions and quantities separate.
The same outline can lead to different supplied products. A change in colour, fitting or packaging should remain visible in the brief.

Illustrative version A
Navy and coral design; individual pin; fitting and presentation to confirm.
Illustrative version B
Forest and sage colour direction; quantity listed separately; any other change identified.
Illustrative paired set
Two specified versions supplied together; set composition, presentation and quantity unit to confirm.
Use your own version names and quantities when enquiring. The examples do not imply a stocked set, fixed specification or minimum order quantity. Separate confirmed information from questions that still affect the quotation scope.
Give feedback that identifies the change.
Make each comment traceable to a named artwork version or sample reference. Keep the requested change separate from the features you want to retain.
Reference
Name the artwork, version or sample being reviewed.
Observation
Identify the exact part of the product and explain what you see.
Requested change
Describe the intended result or the question you need resolved.
Keep
State which design features and supplied requirements should remain unchanged.

Artwork review concerns the design and the requirements recorded in it. A physical sample allows discussion of surface, reverse, connection and presentation within the agreed scope. Approval of an image is not described as inspection of a physical product.
Six cooperation handovers.
Cooperation keeps the references and decisions clear between your team and ours. Each handover has an input to share and a result to agree.
Share the existing design

Your input
Send the artwork, intended business use and important identity details.
Agree together
Identify the available material, open questions and any further input required.
Define versions & supplied form

Your input
List each design, version, estimated quantity, fitting and presentation requirement.
Agree together
Bring the product scope and counting units into one brief, with provisional decisions marked.
Review artwork & samples

Your input
Collect feedback against named references and identify the feature concerned.
Agree together
Discuss the proposed changes, retained features and any further review or sampling needed.
Confirm production arrangements

Your input
Bring the selected reference, quantities, timing direction and review requirements together.
Agree together
Confirm the actual scope and arrangements before treating the brief as a manufacturing instruction.
Review product & presentation

Your input
Compare the relevant product features and supplied arrangement with the agreed reference.
Agree together
Identify questions that need clarification or further action for the project.
Discuss packing & dispatch

Your input
Share the receiving requirements, quantity units and information needed by your team.
Agree together
Confirm the packing and dispatch arrangements for the actual order.
This is a cooperation framework, not a fixed-day schedule. Sampling, costs, timing and commercial terms are confirmed for the individual project.
How the physical product progresses.
Manufacturing changes the object. The illustrated geometric pin below is a separate manufacturing example; it is not a production record of the shield pin.

Manufacturing reference
The design version, size direction, construction, surface and fittings provide the inputs.
Resolve open decisions before the reference is treated as an instruction.

Tooling & metal form
Tooling and the metal body express the agreed outline, relief and connection points.
The defined form carries the design intention into the next work.

Colour & surface work
Enamel colouring, polishing and plating are arranged for the selected design and finish.
The surface-related operations do not follow one universal order.

Fittings & assembly
The body is brought together with the specified fixing or connection.
The supplied scope may be an assembled accessory or agreed components.

Product review
Relevant features and the supplied arrangement are compared with the agreed reference.
Identify the version and specific question when feedback is needed.

Packing preparation
Protection, presentation and packing are organised around the product and quantity unit.
Clarify versions, pieces or sets and the dispatch information to confirm.
The sequence is illustrative. The actual manufacturing route is defined for the product, material, structure and finish.
Agree the product and packing review.
Quality discussion is more useful when it names a feature and a reference. The supplied arrangement belongs in that discussion alongside the pin itself.

Review against
Identify the agreed artwork, specification or sample relevant to the feature. Resolve differences between references rather than assuming they answer the same question.
Identify
Consider colour areas, boundaries, front and reverse, dimensions, fittings, versions and quantity units. State which parts matter to your purchasing review.
Clarify
Discuss the presentation, protection and any supporting information your team requires. Review methods, conditions and available records are confirmed for the project.
No inspection percentage, acceptance level, certificate or test programme is implied by the illustration. Share any particular requirement before manufacturing arrangements are agreed.
The factory behind the brief.
Green Frog Supply is operated by HANGZHOU FORTHRIGHT TRADE CO., LTD in Hangzhou, China. Our own factory connects the design discussion with the work needed to supply the product.

Our in-house scope includes tooling, metal forming, enamel colouring, polishing, electroplating, assembly, inspection and packing. The tooling and assembly views illustrate two different parts of that scope; the environment image provides broader work-area context.
In-person visits and video factory reviews are available by appointment. Project-specific factory and quality information can also be discussed for your purchasing review. The agenda and actual materials are confirmed for the project.


Changes and repeat orders need a reference.
A new request should show what continues and what changes. Identify the stage the project has reached so the effect of the request can be reviewed.

Keep
Name the previous design or sample reference and the requirements that remain applicable.
Change
List changes to artwork, colour, structure, fitting, quantity or packing. Identify the requested timing.
Reconfirm
Discuss the effect on work, cost and arrangements. For a repeat order, confirm the current quantity, versions, presentation and schedule.
An earlier order does not establish permanent tooling storage, automatic repeat production, free changes or unchanged commercial terms. Confirm the current project rather than relying on assumptions.
OEM questions, answered.
Practical questions about files, versions, samples and the scope to discuss.
01What should our company send for an OEM enamel project?
Send the artwork or reference you have, the intended business use, product type and target size direction. Add estimated quantities for each design or version, your finish and fitting requirements, packing needs and target timing. Mark provisional decisions clearly. This helps us discuss the manufacturing scope and identify what still needs to be defined before arrangements are agreed.
02Can we begin if we only have an image rather than editable artwork?
You can share the available image to explain the design and the features your team wants to retain. Its suitability for manufacturing needs to be reviewed with the intended product size, detail and construction. We will discuss what additional artwork or clarification is needed. An image is a starting reference, rather than a guarantee that it can be used directly for production.
03How are small lettering and fine details reviewed?
Identify the wording or detail that matters to your organisation and show it at the intended product size. Lettering, metal divisions, colour areas and the outline need to be considered together. A detail may require discussion about its size, spacing or representation. Any proposed change should be reviewed against your design priorities; we do not publish one minimum-detail rule for every product.
04Should different colours or fittings be listed as separate versions?
Please identify each version and its quantity, including changes to colour, visible metal, fittings or presentation. Explain whether the quantities refer to individual pieces, components or complete sets. A shared front design does not necessarily mean the supplied products are identical. A clear version list helps define the scope without assuming that one specification covers every item.
05What is the difference between reviewing artwork and reviewing a sample?
Artwork helps define the design, outline, colour arrangement and other recorded product requirements. A physical sample allows discussion of the actual surface, reverse, fittings and supplied presentation within the agreed scope. Feedback should identify which reference is being reviewed. Approval of an artwork image should not be described as a completed inspection of a physical product or its assembly.
06Can an OEM order include assembly and packaging?
Yes. Our in-house scope includes assembly and packing, and the supplied arrangement is discussed for the project. State which fittings belong with the product, whether any assembly remains with your team, and what presentation, protection or packing you require. Confirm the counting units and versions as well, so that the brief describes what should arrive together.
07How should we request a change after a reference has been agreed?
Identify the reference version, the exact feature to change and what should remain unchanged. Tell us whether the request concerns artwork, product structure, finish, quantity, fitting or packing. The effect on the work, cost and timing needs to be reviewed for the stage the project has reached. Changes are not assumed to be included automatically or at no cost.
08Can a repeat order use the previous product reference?
Share the previous project or product reference, together with the quantity, required versions, packing and timing for the new order. We need to confirm which requirements still apply and which have changed before new arrangements are agreed. A previous order does not by itself confirm current manufacturing arrangements, tooling availability, identical commercial terms or an automatic repeat-production schedule.
09Is the OEM work supported by your own factory?
Green Frog Supply is operated by HANGZHOU FORTHRIGHT TRADE CO., LTD in Hangzhou, China. Our in-house work includes tooling, metal forming, enamel colouring, polishing, electroplating, assembly, inspection and packing. In-person visits and video reviews can be arranged by appointment. Project-specific factory and quality information can be discussed, with the actual agenda and materials confirmed individually.
10How are order quantity, cost and timing confirmed?
Provide the design, product type, versions, estimated quantities, target timing and supplied arrangement. Detail, construction, finish, fittings, sampling and packing all affect what needs to be assessed. We discuss the actual project rather than applying one published promise to every enquiry. Required design deliverables, order quantities, costs and schedule must be confirmed before they are treated as agreed terms.
Look at a defined product brief.
These published custom concepts show different decisions to discuss. They are examples, not stocked products or customer cases.
Bring the known and open points.
Share the design you have and the decisions that still need discussion. Identify each design or version and the supplied arrangement you are considering.
