Plastic Diffuser For LED Strip

A: The two 42 x 7mm polycarbonate covers are the channel lenses in this range, and the 40 x 5mm Sabic 945A profiles suit narrower housings. Match the cover width to the inner slot width of your channel, then check the 1.1mm wall against the slot depth. Channel tolerances vary between brands, so send the channel drawing or post a short sample and the fit is checked before any tooling is cut.

A: From 300kg total weight. Extruded profiles are priced by weight, so that converts into very different metre counts depending on the section: at 73g per metre it is a long run, at 190g per metre considerably shorter. Tell us the profile and the length you need and the quantity is converted for you before you commit, whether that is a first trial run or a bulk repeat order.

A: A new cross section is quoted between $400 and $1500 depending on how difficult the section is, and mold design plus sampling is completed within 72 hours of a confirmed drawing. Mold ownership is agreed order by order and is not published here, so raise it in your enquiry if it matters to your programme.

A: Batches are measured on a translucent integrating sphere against the transmission agreed for your part, inside the 50% to 95% range Dachang works across, and customers can provide original LED light boards so the target is matched on the real light source. Bear in mind that transmission alone does not describe appearance: a clear cover at high transmission still shows the diode line, while a milky or frosted surface trades some output for even luminance along the fixture.

A: Extrusion drag lines are inevitable but can be minimized. Adding a zigzag design to the surface breaks up the reflection, improves appearance and makes the remaining lines much harder to see on a finished fixture.

A: For PC, flat and wide designs with appropriate thickness keep enough flexibility for roll packaging, which cuts freight volume noticeably on container quantities. Acrylic cannot be rolled because PMMA is brittle, so acrylic covers always ship as straight cut lengths. Confirm which applies to your section before you plan packing and container loading.

A: Yes, and a physical sample is usually faster than a drawing because it carries the wall thickness, snap geometry and surface finish all at once. If your existing part is qualified to a specific grade, name it. The grades used across this range, Sabic 945A, Iupilon E-2000, Makrolon 2805 and Panlite ML-7500ZCL, behave differently on transmission and flame rating, so matching the look without matching the resin can still fail your approval.

A: We specialize in extrusion profiles. For end caps, we can coordinate with cooperating manufacturers to produce them together upon request, so the cover and its caps arrive as one matched set.

A: Polycarbonate LED strip light diffusers are widely used in commercial lighting, architectural installations, retail displays, industrial facilities, refrigeration cabinets and outdoor environments where durability and impact resistance are essential.
