Frequently Asked Questions

Explore these common queries about extruded diffusers and plastic profiles manufacturing. Contact us for further assistance!
What types of materials do you use for your light diffusers, and what are the size ranges?

We primarily use high-quality polycarbonate and acrylic in our extrusion process to manufacture light diffusers. Both materials offer excellent light transmission and durability. We can also produce custom materials as customer requires. Our production size ranges from 3mm to 200mm in width and 0.3mm to 10mm in wall thickness.

Do you offer different levels of light diffusion?

Yes, we offer a wide variety of diffusion levels. From clear lenses that provide maximum light transmission to frosted and opal diffusers that offer a higher degree of diffusion, we have options to suit various lighting requirements and achieve the desired light effect.

What is the maximum length of diffuser you can produce in a single extrusion?

Our standard maximum length for a single extruded piece is typically around 6 meters. However, we can create longer lengths by connecting multiple pieces, and for some specific products, we can make it over 50 meters in one roll.

Can you produce custom shapes for led diffusers, such as tubes and rods?

Yes, we specialize in custom plastic extrusion. We can create diffusers in various shapes, including tubes, rods, and other complex profiles, to match your specific design needs. We can even make thin, rigid profiles or shapes that can slightly bend.

Can your diffusers be used for both indoor and outdoor applications?

While many of our products are suitable for indoor use, we also offer UV-stabilized polycarbonate diffusers and acrylic diffusers that are designed for outdoor applications. These are more resistant to weathering and can withstand exposure to sunlight without yellowing or becoming brittle.

Can your led light diffusers be used in advertising, display or wall applications?

Absolutely. Our led light diffusers are commonly used in retail displays, signage, and other advertising applications, including being mounted on walls. The smooth, even light they provide can help showcase products and attract attention. A thin, translucent diffuser can be used to create a backlit display with uniform illumination.

Are your plastic light diffusers compatible with dimming systems?

Yes, our diffusers are generally compatible with most LED dimming systems. They will not interfere with the dimming function and will continue to provide smooth, even light distribution at different brightness levels.

Are your light diffusers suitable for use in the automotive industry?

Yes, our durable polycarbonate diffusers are used in automotive lighting applications, including interior ambient lighting, dashboard displays, and exterior lighting components. They offer excellent light transmission and can withstand the demands of the automotive environment.

Can your led diffuser be used in agriculture to improve plant growth?

Yes, our LED diffusers are increasingly used in agricultural settings, particularly in vertical farming and greenhouses. They ensure that plants receive uniform light distribution, promoting healthy growth and maximizing yields.

What is the lead time for a custom led strip light diffuser order, and do you ship internationally?

The lead time for custom orders depends on the complexity of the design, size, and quantity. Generally, it ranges from 2-3 weeks. We will provide a more accurate lead time estimate after we review your requirements.We offer international shipping to serve our global clients.
