Wholesale Transparent Color Acetate Injection Optical Frame with Spring Hinge

An acetate injection front in a transparent colour with a metal spring hinge, moulded at 51-20-145 for a men's line that needs a crystal look at volume.

Overview

Acetate injection sits between sheet acetate and plain plastic: the material is acetate, but the front is moulded from pellet rather than cut from sheet, which lowers cost and gives tighter control over wall thickness on complex shapes. The result is a frame with acetate depth of colour and a metal spring hinge at a price point that suits volume retail. Transparent fronts expose the hinge block and the lens seat, so the internal surfaces are polished to the same standard as the outside.

Moulded fronts are dimensionally consistent, which matters when a buyer orders the same model across seasons and expects the lens to drop in without reworking. Sizes are fixed by the mould, and the size printed on the temple matches the drawing within tolerance. The spring hinge is riveted into a reinforced seat, because a transparent front shows any stress whitening around the rivet immediately. Transparent and two-tone effects come from controlling melt and mould temperature rather than from painting, so the colour survives daily cleaning and does not wear at the edges.

Key Features

Product Showcase

Views show the OAI435369 sample and, where noted, a sister model from the same range, so the hinge position and temple profile can be compared before a sample is ordered.

Specifications

The values above come from the current specification sheet for this model. A size marked as fixed by the mould cannot be changed without new tooling, while colour, logo, lens and packing remain adjustable within the stated minimum.

OEM & ODM Customization

A wholesale transparent color finish shows every internal mark, so the mould is cleaned and the melt held steady through the run. The acetate injection front is moulded at 51-20-145, the injection optical frame carries a metal spring hinge, and the transparent color is approved on a moulded chip rather than a printed card.

Customisation on an injection frame is mostly a question of what the mould already allows. Colour and finish can change freely, logo can change freely, and packaging can change freely; geometry changes require a new insert or a new mould. We quote those two paths separately so a buyer can see the cost of a new shape against the cost of a new colour before deciding.

• Finish: solid, transparent, translucent and two-tone finishes are quoted from the same mould, with per-finish minimums confirmed at quotation stage.
• Colour: matched to a physical swatch or Pantone reference; transparent tones are approved on a moulded chip rather than a printed card.
• Hinge: spring and standard hinge options are available, and the hinge grade is stated on the specification sheet.
• Logo: hot stamp, laser and silkscreen are priced per position, with a proof issued before production.
• Packaging: sleeve, pouch and case options are quoted per unit, including barcode labels applied at packing.
• Documentation: CE and FDA files follow the model number, and the lens specification is listed on the declaration.

Buyers who want the wider picture can review the OEM and ODM optical frames programme, which explains how tooling, sampling and documentation are handled across models.

Manufacturing & Quality Control

Production is organised around four checkpoints, and a frame cannot move to the next stage until the previous one is signed off. The process below is the same for a sample order and for a repeat run.

Inspection records are kept against the model number, so a question raised months after shipment can be traced back to the batch, the operator and the material lot. The full procedure is described under quality control.

Applications

• Optical chains needing an acetate look at a plastic price
• Distributors supplying transparent and crystal frame trends
• Online brands shipping lightweight frames in volume
• Department store optical counters with seasonal colour changes
• Duty-free and travel retail programmes
• Buyers testing a new shape through a low tooling entry

The injection range is listed with custom men optical frame and pairs with custom optical frame styles when a buyer needs a full family across materials.

FAQ

What is the difference between acetate injection and sheet acetate?

Sheet acetate is cut and reamed from a block, which allows deeper colour and hand adjustment. Injection acetate is moulded from pellet, which is more repeatable and less expensive at volume but fixes the geometry in the mould. Both are acetate; the choice is a cost and tooling decision.

Can I order a mixed colour run?

Yes, when each colour meets its own minimum. MOQ for this model is 600 pieces, and the colour split is confirmed at quotation stage so the per-colour minimum is clear before the order is placed.

How is a transparent colour approved?

On a moulded chip, not on a printed card. Transparent acetate shifts with wall thickness and lighting, so approval on the actual material is the only reliable method.
