What to specify for a custom polycarbonate diffuser order
This product is a polycarbonate light diffuser extrusion made as a continuous profile. Its value to an OEM buyer lies in matching the section and visible finish to the actual lighting assembly. The listing does not identify a fixed size or optical target for this item, so your drawing and acceptance requirements should lead the quotation.
| Material | Polycarbonate (PC). State a particular grade if your project requires one. |
|---|---|
| Cross-section | Send a drawing or sample showing the mating surfaces and any features needed to locate or retain the cover. |
| Dimensions | Provide the section measurements, required cut length and tolerances that determine fit. |
| Appearance | Describe the surface finish and the visible result you need from the completed fixture. |
| Order scope | Include initial quantity, expected repeat volume, delivery destination and target schedule. |
No product-specific transmission figure, resin grade, certification number, MOQ or lead time is published for this item.
How the extruded PC diffuser supports your fixture design
Start with fit
Extrusion can produce complex profile shapes and different wall thicknesses. Define the actual housing interface first, so the proposed section is judged by how it assembles rather than by a catalog photo alone.
Specify the visible surface
Surface requirements can be discussed for this extrusion. Tell us what the diffuser must look like in the lit fixture and which areas remain visible when the light is off.
Keep the quote comparable
Material, shape difficulty, quantity and product requirements set the price. Share the same inputs with each supplier when comparing offers for a custom LED light diffuser profile.
Develop an OEM diffuser profile around your fixture
Dachang supplies custom-extruded PC diffuser profiles for lighting OEM inquiries. For a new fixture, send the proposed section and explain how the cover fits the housing. For a replacement part, send the existing sample and identify the fit or appearance issue you need to solve. Those details let the factory assess a custom extrusion rather than quote an assumed stock profile. For other lighting parts, see our lighting polycarbonate profiles.
If your specification calls for an additive or a particular surface treatment, include the requirement and its test method. Anti-fog and anti-scratch additives can be discussed, but they are not standard features of this item.
A useful RFQ contains
A drawing or sample
Show the cross-section and how it meets the housing.
Acceptance requirements
State critical dimensions, material, surface and appearance targets.
Commercial scope
Give the order quantity, delivery location and intended timing.
Agree on PC diffuser inspection requirements before production
Polycarbonate is the specified material for this product, while a precise resin grade and test result remain job specific. Put any required material declaration, optical test, dimensional check or customer approval step into the inquiry. Ask for written confirmation of the selected specification and review a sample in the intended fixture when fit or appearance is critical.
Extruded profiles can vary slightly in size as the plastic leaves the die. Mark the dimensions that matter most to assembly so we can review tolerances against the proposed shape before you commit to a production order.
Get a bulk quote for your polycarbonate diffuser profile
Price depends on the material, section complexity, order quantity and other product requirements. A larger committed quantity may affect the offer, but there is no published price break for this profile. Request the MOQ, tooling scope, sample plan, packing method and delivery date together so your purchasing team can evaluate the full order rather than a unit price alone.
If the material or geometry comes from your customer, you can keep those details in a direct exchange with Dachang. Send enough information to price the work, then confirm the final drawing and acceptance criteria in the purchase documents. Profiles with several functional features are handled like our complex plastic profiles.

Questions buyers ask about this PC diffuser extrusion
Q: Can I request a custom profile instead of the shape shown?
A: Yes. Different shapes and thicknesses can be extruded. Dachang can review your drawing or sample for a project-specific quotation; the pictured section does not define every available design. You can also compare it with our standard polycarbonate light diffuser.
Q: What should I send to get a meaningful quote?
A: Send the cross-section drawing or a sample, critical fit dimensions, material requirement, visible finish and intended quantity. Include destination and timing so we can address the commercial terms in the same reply.
Q: Does this listing confirm a light transmission value or certification?
A: No product-specific optical value or certificate number is published here. State the performance or compliance requirement in the RFQ and request evidence for the selected material and finished part before approving it.
Q: How will MOQ and lead time be set for an OEM order?
A: Neither term is published for this diffuser. Dachang quotes according to material, shape difficulty, quantity and product requirements, so ask for MOQ, sample timing and production timing with your proposed design.
Q: Can I discuss customer-specific material requirements privately?
A: Yes. Share the relevant grade, test method and drawing requirements directly with our sales team rather than relying on a public product description. Ask that the agreed specification be recorded in the final quotation and order documents.
