Product Overview
Eyewear fittings join or retain parts of a frame in a compact space.
The focus is the small mechanical interface, not a claim that a generic metal collection is an exact eyewear drawing.
Structure & Mating Interfaces
Provide the frame and temple interfaces, pivot arrangement and any adjustment or stop feature.
Identify surfaces exposed to the user and the required finish.
Engineering Focus
Why distinguish frame attachment from pivot movement?
The attachment locates the fitting on the frame, while a pivot may establish movement.
Combining them into one general fit requirement hides the different surfaces that control each.
The frame and temple drawings provide the references needed to assess both.
Manufacturing Route & Finishing
Compare MIM for integrated small shapes with machining or other suitable forming routes.
Pin holes and working contacts may need post-forming finishing.
The proposed route is confirmed for your drawing, material and quantity. An image does not establish a fixed tolerance or a complete process specification.
Compare manufacturing capabilities →Materials & Surface Requirements
Define base material, final condition and cosmetic finish separately.
Identify visible faces, permitted edge rounding and the dimensions that must be met after finishing.
Any magnetic, electrical or acoustic requirement needs its own specification.
Review material-selection information →Quality & Sample Approval
Check attachment fit, pivot movement, edges and appearance after finishing.
Use the actual mating frame for the agreed operating test.
Specify the drawing revision and the condition in which each dimension is inspected. Record the agreed dimensional and functional checks before sample approval.
Quality documentation →Prepare a Product-Specific RFQ
- Component definition. Send the 2D drawing and 3D model, where available, with the drawing revision and the requested part or assembly scope.
- Mating information. Include the assembly references needed to define the interfaces discussed above.
- Delivered condition. State material, finishing and inspection requirements, identifying any items that need a manufacturing recommendation.
- Supply plan. Include sample needs, expected order and annual quantities, packaging requirements and target timing.
Product Questions
Can eyewear hardware be selected by visual resemblance?
No. Frame connection, pivot geometry and user-contact requirements must be confirmed for the intended model.

How are appearance and functional fit checked?
Check attachment fit, pivot movement, edges and appearance after finishing. Use the actual mating frame for the agreed operating test.
Technical Context
The product-specific notes above identify drawing-review questions. General process and material references are collected separately; they do not verify a material grade, production qualification or performance claim for the pictured part.
