Briefing
Detailed
A CP optical front specified with a plastic spring hinge, which keeps the weight down while still letting the temple flex under a one-handed pull.
Overview
CP, or cellulose propionate, is the material behind most value-priced plastic frames, and it earns the position: it moulds cleanly, takes deep colour, and resists the stress cracking that ruins cheaper styrene fronts. This frame is produced from CP granule in a steel mould, so the shape is fixed and the unit cost stays low at volume. A plastic spring hinge is the cheaper of the two spring options and the lighter one, and on a value frame that matters more than the marginal gain in durability a metal hinge would bring.
The build targets buyers who need a dependable plastic optical frame at a competitive landed cost: chain stores, pharmacy optical counters, export distributors and promotional programmes. Hinges are chosen per price point, and the frame can be supplied with a plastic spring hinge where the extra flexibility is worth the cost step. The hinge seat is moulded with extra wall thickness behind it, because that is where a plastic spring hinge fails first when a frame is opened past its limit. Colour is set in the mould rather than sprayed, so a scratch on the rim does not expose a different tone underneath.
Key Features
Cellulose Propionate Front
CP granule is dried, melted and injected into a polished steel mould. The material takes saturated colour well, keeps its gloss after polishing, and holds up to the knocks a frame receives in a display tray, which is why it remains the default for value optical lines.
Hinge and Temple Choice
The hinge is the part that decides how long a plastic frame feels new. A spring hinge lets the temple flex outward without cracking the hinge seat, while a standard hinge keeps the cost lower and suits markets where frames are replaced on a shorter cycle.
Fixed Size, Stable Fit
Injection moulding fixes lens width, bridge and temple length, so the size printed on the arm is the size delivered on every reorder. That consistency matters when a chain distributes the same model to hundreds of doors and needs lenses to drop in without adjustment.
Colour and Logo in the Mould
Solid colours are matched to a swatch or Pantone reference, with Any colour, matched to a swatch in the standard range, and transparent tones are controlled through melt and mould temperature. Logo is applied after moulding by hot stamp, laser or silkscreen, or set into the mould for a raised mark.
Product Showcase
Views show the OCP310420 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.

OEM & ODM Customization
A custom cp optical frame is specified here with a plastic spring hinge rather than a metal one, which keeps the weight low and the cost predictable while still giving the temple enough flex for daily handling. The cp optical frame is the base model, and because the optical frame shares its front with the standard hinge version, a plastic spring hinge can be sampled on the same shape before the order is placed.
Cost engineering is the core of a CP project. Because the tooling carries the shape, the levers that change price are wall thickness, hinge grade, colour complexity and packaging, not the front design itself. A buyer who can accept an existing shape and change only the colour and logo gets the shortest path from approval to shipment, and the sample confirms those choices quickly.
- Shape: existing moulds can be re-coloured and re-logoed; a new shape requires a dimensioned drawing and a tooling quotation.
- Hinge grade: standard, spring or screw-fixed hinges are quoted separately so the price step is visible before the order is placed.
- Colour: solid, transparent and tinted options are matched to a physical swatch, with per-colour minimums confirmed at quotation stage.
- Logo: hot stamp and silkscreen suit flat temple surfaces, while laser marking gives a finer line on dark colours.
- Packaging: polybag, pouch, hard case and printed sleeve are priced per unit, and mixed packing across colours is possible within one carton.
- Compliance: CE and FDA documentation is issued per model, and the lens specification on the declaration matches the shipment.
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.
1. Granule and Colour Check
Each granule batch is checked for moisture, colour concentrate ratio and contamination before drying. A wrong masterbatch ratio is the most common cause of shade drift in plastic frames, so the first shots of every run are compared with the approved colour chip.
2. Moulding and Trimming
Frames are injected, cooled on fixture to limit warp, then trimmed and deflashed by hand. Hinge seats are checked for flash and screw thread condition before the temple is attached.
3. Assembly and Fit Test
Temples are fitted, hinge tension is set, and each frame is opened and closed repeatedly to confirm return. Bridge width and temple parallelism are measured on a flat plate so the frame sits level on a counter.
4. Packing and Carton Audit
Frames are wiped, sleeved and counted, with a sample drawn from each carton for colour, logo position and hinge feel. Carton marks and barcode labels are checked against the buyer's instruction before sealing.
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
- Chain optical stores needing a low-cost house frame
- Pharmacy and supermarket optical counters
- Export distributors serving price-sensitive markets
- Promotional and seasonal frame programmes
- Safety and protection eyewear ranges where a plastic front is required
- Online sellers testing new shapes before committing to tooling
This CP model is catalogued under custom men optical frame, and buyers building a matched family often combine it with the custom optical frame range for other face shapes.
FAQ
Why can the size not be changed on a CP frame?
The size is set by the steel mould. Changing lens width, bridge or temple length means cutting a new mould, so for this model the size is fixed at the value shown and colour or logo remain the adjustable variables.
What is the minimum order quantity?
MOQ is 1200 pieces for this model. A mixed order across two or three colours is accepted when each colour reaches its own minimum, and the exact split is confirmed at quotation stage.
Which certifications are available?
CE and FDA documentation is issued against the model number, covering the frame material and the lens specification shipped. If your market needs additional testing, the requirement is quoted as a separate item.
