Introduction: Why MOQ, Tooling Cost and Lead Time Are Connected
A quotation for 600 frames means little until the specification is fixed. Split that order across six colors and the production economics change. Add a proprietary hinge and the development schedule changes too.
Brands comparing custom eyewear manufacturers need to look at those dependencies. MOQ reflects purchasing and production batch constraints. Tooling cost follows the engineering work required. Lead time includes approval delays as well as factory work. Changing one requirement can move all three .
Start with construction. An injection frame needs a different production route from a machined acetate frame. A new shape does not automatically require the same tooling investment in both.
Customization depth matters just as much. A printed temple logo is a different job from a recessed metal badge requiring a mounting feature.
Then consider the complete product. Polarized lenses may introduce separate sourcing requirements. A custom case can have its own minimum order. Testing for the destination market also needs a place in the budget and schedule.
The useful question is where the minimum comes from. Ask the custom glasses manufacturer to identify the constraint.
Injection molding involves machine setup and material preparation. Acetate orders depend on available sheet stock. Metal frames may require dedicated component batches and finishing runs. For armações de óculos, a custom bridge or hinge can impose a minimum beyond the frame assembly requirement. Especially when dealing with premium materials like Italy Mazzucchelli acetate, Zeiss lenses, or OBE hinges.
| Frame Material Type | Minimum Order Quantity (MOQ) | Average Production Lead Time | Best Strategic Use Case |
| Machined Acetate Frames | 300 pcs | 75 – 90 Days | Premium independent brands; complex colorways |
| Pure Titanium Frames | 300 pcs | 75 – 90 Days | High-end optical lines; lightweight luxury market |
| Plastic Injection Frames | 600 pcs | 40 – 60 Days | Mass-market fast fashion; high-volume promotional |
| Standard Metal Frames | 600 pcs | 40 – 60 Days | Geometric wire-frames; standard sun and optical lines |

A stock case with a printed logo may suit a trial order. A specially constructed case introduces another supplier’s production minimum. Frame MOQ and packaging MOQ need separate confirmation.
A reorder forecast can support component planning. It is not a commitment to buy unless agreed. Ask whether scheduled releases are possible and who carries the unused stock.
The drawing matters more than the word “custom.” Have the factory identify which features require new tooling.
An existing injection frame may accept a new color without geometry changes. Changing its bridge width can require mold modification or replacement. Machined acetate frames follow a different route: new cutting programs and fixtures may matter more than a frame mold. OEM and ODM labels alone cannot settle the cost.
Separate engineering work from tool manufacture. Clarify whether trials and corrections are included. Sample charges may be separate again. A custom eyeglass manufacturer should distinguish initial development costs from charges that repeat on every order.
Check how tooling is recovered in the price. A quotation with no separate tooling line may recover development through the unit price. Compare the total spend at the intended order quantity, then ask how repeat-order pricing changes.
Who owns the tooling after payment? Can it be transferred? What maintenance is included? Establish revision charges and any order-based credit in writing. Payment for a tool does not automatically establish exclusive use.
At SUSON, we sign strict NDAs before you share any buyer-owned designs, and our in-house mold workshop ensures your proprietary tooling remains exclusive to your brand.
💡 Want to know if your design requires a new mold? Send your 2D/3D drawings to SUSON, and our in-house engineering team will provide a free mold assessment with NDA Protectionwithin 24 hours.
Ask when the quoted clock starts. Deposit receipt and approved samples are different milestones.
SUSON’s workflow moves from design confirmation into specification review and quotation. Mold development and sampling follow the agreed solution. For buyer-owned designs, the process includes an NDA.
O pre-production sample gives bulk production an agreed reference. Approve fit and dimensions against the specification. Check the finish and branding too. A late temple-logo change can require another approval cycle even when the frame itself is ready.
Color approval deserves a physical reference. A translucent brown temple can look convincing in a photograph yet differ under shop lighting. Specify the reference sample and viewing conditions before approval. Otherwise, the buyer and factory may be accepting different versions of “brown.”
Material availability and factory capacity shape the production window. A booked assembly slot is little help if the hinges have not arrived.
Allow time for inspection and possible rework before packing. Keep shipping transit separate from factory lead time. A promised dispatch date is not an arrival date. Ask for dated milestones rather than one unexplained delivery estimate.

For a market test, start with an existing frame and fewer colors. Spend the development budget on features customers will notice.
Freeze artwork before sampling. Specify the logo dimensions and position; “slightly smaller” is not a production instruction. Confirm packaging early enough to avoid finished frames waiting for boxes.
Shared components can simplify a collection, but combining unrelated SKUs does not necessarily reduce their individual minimums. Split deliveries may ease inventory pressure without reducing the committed production quantity. Get both figures into the agreement.
Use this checklist when comparing quotations from an eyewear manufacturer:
A factory management certificate does not replace product testing. Check which model a report actually covers.
Those controls need to carry through into the order. SUSON connects OEM/ODM customization with sampling and bulk production approval. Existing designs offer a starting point for branding; buyer-owned designs enter a specification and development process.
Its quality control process covers incoming materials through finished products, including dimensional and surface checks. Discuss these inspection points alongside the quotation so the approved frame and delivered batch are judged against the same requirements.
It depends on the specification and batch constraints. Request separate minimums for each color and packaging option.
No. Branding an existing frame may avoid new frame tooling.
Use available components and approve complete specifications before bulk production.
Send SUSON your frame drawing or reference model with quantities by color. Include the destination market and required arrival date. Our in-house engineering workshop and strict NDA protocols protect your exclusive designs from day one.
