A sunglasses sketch can look finished while leaving the factory with unanswered questions. How thick is the temple near the hinge? Where is frame width measured?
For brands planning sunglasses OEM production, the real task is turning design intent into measurable requirements. A production-ready specification needs defined materials and dimensions with agreed tolerances. It also needs a sample approval record and inspection criteria. Otherwise, someone on the production floor has to guess.
A tech pack combines drawings with construction details. It should identify the frame geometry and lens shape. Material choices belong alongside color references; logo artwork needs positioning instructions. Packaging requirements matter too.
The weak point is usually interpretation. “Standard hinge” leaves the component open to substitution. “Same as reference” is worse when the reference exists only in a photograph.
Assign the pack a model number and revision date. Every supplier conversation should refer to that version.
An OEM sunglasses manufacturer needs to check whether the drawing can actually be built at the target cost. A thin temple might lack space for the selected hinge. A decorative insert may require additional tooling.
Flag unresolved details before asking for a firm price. Confirm the quantity per color and the destination market. Testing requirements can change the quotation.
SUSON’s OEM/ODM customization process includes specification discussions and production solution confirmation before quotation. Use that stage to resolve construction questions while changes are still inexpensive.
Stuck on Your Eyewear Tech Pack?
Unsure if your temple thickness matches your chosen OBE hinge? Send your rough sketches or CAD files to SUSON. Our in-house engineering team will perform a Free Manufacturability Review (DFM) under a strict NDA within 24 hours.
Record lens width and bridge width. Add temple length and overall frame width. Lens height alone does not define the lens outline; the drawing also needs its shape and curvature. Specify temple angle and thickness at identified locations.
Give each critical dimension a measurement method and an agreed tolerance. For illustration, a 145 mm frame width with a proposed tolerance of ±0.5 mm is inspectable. The factory must confirm that tolerance against the construction and process.
Avoid applying one tight tolerance everywhere. Concentrate on dimensions that control assembly and fit.
Acetate suits polished frames with layered color effects. TR90 is useful where low weight and flexibility matter. Stainless steel and titanium require different joining and finishing decisions. They are not interchangeable entries on a purchasing sheet.
Para polarized sunglasses, identify the lens material separately from polarization. Define tint and thickness. Specify required UV performance and coatings; a dark lens is no proof of UV protection.
Include hinge construction and nose pad material in the bill of materials. Record the temple core where used. Require approval before substituting components.
“Matte black” is not a complete finish specification. Two samples can share the same color yet look different because their surface texture differs.
Use a Pantone reference where appropriate, backed by an approved physical sample on the intended material. Agree on viewing conditions. Transparent acetate needs particular care because thickness affects its appearance.
Dimension the logo from a fixed feature such as the hinge center. State the application method. Small lettering that works in print may lose definition when engraved.
Use sampling to answer specific questions:
Check frame symmetry and lens seating. Open both temples and compare their resistance. Wear the frame long enough to notice pressure behind the ears.
Suppose a sample looks right but its temple rubs the frame when folded. Record the interference and check the clearance again on the revised sample.
Sign off a Golden Sample linked to the final specification revision. Keep matching references with the brand and factory.
State which reference governs each requirement. The sample may define surface appearance, while the drawing controls dimensions. Resolve any conflict before authorizing the order.
Inspection needs written acceptance criteria. SUSON’s eyewear quality control covers incoming materials and production-stage checks alongside finished-product inspection. Agree on what inspectors should accept before the order starts.
Support this checklist with defect photographs and agreed sampling rules. UV performance requires testing; visual inspection cannot establish it. Set applicable test methods and limits for the destination market. Add impact or coating tests where required by the product specification or applicable rules.
Tie the quotation to the approved specification revision. A lens upgrade after approval can change both price and delivery.

Clarify when the production clock starts. Sample approval and deposit receipt may both be prerequisites. Record who owns the tooling and how later revisions are charged.
Ask a prospective sunglasses OEM manufacturer to identify problems in the pack. Useful feedback is specific: a hinge clearance issue or a finish that needs a different process.
Request examples of comparable constructions. Check how revisions reach the workshop and who authorizes component changes.
For a project requiring eyewear manufacturing and export support, SUSON handles work from model design through finished products. Agree on approval responsibilities and shipping arrangements during the technical discussion.
These details help keep the handoff practical.
Include dimensioned drawings and material specifications. Add color references with vector logo artwork. Supply packaging instructions and editable CAD files (such as .STP, .STEP, or .DWG) to ensure seamless engineering transition. keeping revision identifiers consistent.
There is no fixed count. New constructions may need several corrections. Approve a representative pre-production sample before releasing the bulk order.
Yes. SUSON offers custom development covering dimensions and materials as well as construction processes. Send the current drawing with the problem clearly marked so proposed changes can be assessed.
Before releasing a sunglasses OEM order, make sure the drawing and approved sample agree. Send your tech pack to discuss your OEM/ODM project with SUSON. Include the target quantity and sales market so the discussion can move directly to production requirements.
