OEM/ODM

After the customer approves:

• Product specification
• Price
• Quantity
• Color
• Packaging
• Logo
• Delivery terms
• Payment terms
• Quality requirements

The order can enter formal production preparation.

A production order should contain a clear final approved version.

Typical documents include:

• Purchase Order
• Product Specification
• Approved Sample
• Color Reference
• Logo Artwork
• Packaging Artwork
• QC Requirements
• Delivery Schedule

The approved sample becomes an important physical quality reference for production.

After the order is confirmed, the factory prepares production materials.

For acetate eyewear, this may include:

• Acetate sheets
• Acetate blocks
• Metal cores
• Hinges
• Screws
• Nose pads
• Logo components
• Packaging materials

Materials are checked before entering production.

The purpose is to avoid problems such as:

• Incorrect color
• Material defects
• Surface damage
• Wrong thickness
• Pattern inconsistency
• Hardware mismatch

For precision acetate frames, CNC equipment can be used for controlled cutting and shaping.

Typical processes include:

• Front cutting
• Lens opening
• Outer contour machining
• Temple cutting
• Decorative machining
• Logo processing
• Edge processing
• CNC processing helps improve:
• Dimensional consistency
• Shape accuracy
• Production repeatability
• Batch stability

However, CNC machining is only one part of premium eyewear production.

High-quality acetate eyewear also requires skilled manual finishing.

Hand polishing is an important process for premium acetate frames.

The frame edges are gradually processed to achieve:

• Smooth edges
• Refined surface
• Better transparency
• Improved gloss
• Reduced sharp edges
• Better tactile quality

Depending on the product, polishing may involve multiple stages.

General principle:

Cutting creates the shape; finishing creates the final appearance.

This is particularly important for luxury, vintage, thick acetate, and laminated acetate products.

The next stage involves installing the hardware.

Typical components include:

• Metal hinges
• Screws
• Temple cores
• Nose pads
• Decorative rivets
• Metal logos
• The assembly process checks:
• Hinge alignment
• Opening resistance
• Screw stability
• Temple symmetry
• Hardware positioning
• Connection strength

For products using spring hinges, the hinge mechanism receives additional attention during functional inspection.

After the main components are assembled, frames undergo shaping and alignment.

Technicians adjust:

• Front curvature
• Temple angle
• Left/right symmetry
• Nose area
• Temple height
• Overall frame balance

The objective is to make the finished product consistent with the approved sample.

For optical frames, this stage is particularly important because a small alignment deviation can affect the wearing experience.

For OEM/private-label customers, branding can be incorporated into different parts of the product.

Possible methods include:

• Laser engraving
• Silk-screen printing
• Hot stamping
• UV printing
• Embossing
• Metal logo
• Heat transfer

Customized temple printing

Logo placement may include:

• Temple exterior
• Temple interior
• Lens
• Case
• Packaging
• Cleaning cloth
• Shopping bag

Before mass production, the logo artwork and position should be approved.

For sunglasses or complete eyewear products, lenses can be processed according to the customer's specifications.

Possible lens options include:

• Clear optical lenses
• Tinted lenses
• Gradient lenses
• Polarized lenses
• UV-protection lenses
• Blue-light lenses
• Prescription-compatible solutions
• Customized lens colors

Depending on the destination market and product category, the appropriate testing and compliance requirements should be confirmed before mass production.

After frame processing, hardware, lenses, and branding are completed, the product enters final assembly.

The production sequence may include:

Frame → Hardware → Lens → Logo → Alignment → Cleaning → Final Inspection

Each unit is checked before packaging.

Eyewear packaging can be customized as a complete system rather than as a single case.

A complete packaging solution may include:

Primary Packaging

• Individual glasses pouch
• Microfiber cleaning cloth
• Protective film

Secondary Packaging

• Eyeglass case
• Paper box
• Magnetic case
• PU leather case
• Microfiber pouch

Brand Packaging

• Gift box
• Instruction card
• Warranty card
• Brand card
• Paper shopping bag
• Customized stickers

This allows the factory to provide a one-stop eyewear packaging solution.

Before shipment, packaging is also inspected.

Typical checks include:

• Logo accuracy
• Color accuracy
• Printing quality
• Box dimensions
• Case structure
• Cloth quality
• Accessory quantity
• Barcode
• Label
• Individual packaging

The purpose is to ensure that the packaging received by the customer matches the approved artwork and specification.

Before loading, the factory confirms:

• Total quantity
• Model quantity
• Color quantity
• Size quantity
• Packaging quantity
• Accessory quantity
• Carton quantity

The shipping documents should correspond with the actual shipment.

For B2B customers, this reduces receiving and inventory problems.

Finished products are packed according to the agreed shipping method.

The factory prepares:

• Inner cartons
• Master cartons
• Product labels
• Carton marks
• Shipping labels
• Packing list

Carton protection should be appropriate for the transportation method and destination.

For international orders, the factory can coordinate with the customer's nominated forwarder or shipping partner.

Possible arrangements include:

• Sea freight
• Air freight
• Express
• Door-to-door logistics
• Customer-appointed forwarder

The shipping method depends on:

• Order volume
• Destination
• Required delivery date
• Budget
• Product characteristics

The factory should provide the necessary shipping information and coordinate the loading schedule.

After shipment, the customer receives the goods and performs an incoming inspection.

The recommended receiving procedure is:

Carton Inspection → Quantity Check → Packaging Check → Product Sampling → Functional Check

If the customer identifies an issue, the factory should receive:

• Product photos
• Video evidence where necessary
• Product model
• Quantity affected
• Batch information
• Detailed description

This allows the factory to trace the production batch.

Professional OEM/ODM service should continue after shipment.

If a quality issue occurs, the factory should follow a structured process:

Step 1 - Issue Registration

Record the complaint and affected quantity.

Step 2 - Evidence Collection

Review photos, videos, samples, and production records.

Step 3 - Root Cause Analysis

Determine whether the issue originated from:

• Raw material
• Processing
• Assembly
• Packaging
• Transportation
• Customer handling

Step 4 - Corrective Action

Implement appropriate improvements.

Step 5 - Preventive Action

Modify the relevant production or QC procedure to reduce recurrence.

Step 6 - Customer Feedback

Provide the customer with the investigation result and solution.

This is more professional than simply replacing defective products without identifying the root cause.

For repeat customers, the second order should become more efficient than the first.

The factory can maintain:

• Approved sample
• Technical specifications
• Color references
• Logo artwork
• Packaging artwork
• Production records
• QC requirements

This helps shorten future development time and improve batch consistency.

For long-term customers, the workflow becomes:

First Development → Approved Product → Production Database → Repeat Order → Faster Manufacturing

Once a customer has established a successful product line, the factory can further support collection expansion.

For example:
