Custom Gradient Shade Band PVB Interlayer for Automotive & Architectural Glazing

Blending functionality with premium aesthetics, the Custom Gradient Shade Band PVB Interlayer features a distinct tinted band at the top edge that smoothly fades into absolute clarity. Primarily designed for automotive windshields to act as an integrated sun visor, this innovative film is now rapidly gaining popularity in architectural applications to reduce glare in overhead canopies and facades, eliminating the need for aftermarket window tinting or physical sunshades.

Key Advantages & Benefits

  • Integrated Glare Reduction: The dark upper band significantly reduces eye strain and blinding sun glare without obstructing the primary viewing area.
  • Seamless Color Transition: Manufactured via co-extrusion technology, ensuring the gradient fade is perfectly smooth with no harsh lines.
  • Cost-Effective Manufacturing: Allows glass processors to offer premium tinted windshields without needing to stock separate colored glass panes.
  • Customizable Colors: Available in popular automotive shades including Blue, Green, Grey, and Bronze.

Versatile Applications

  • Automotive OEM and ARG front windshields
  • Bus, coach, and recreational vehicle (RV) glazing
  • Architectural skylights and glass canopies
  • Curtain walls requiring upper-level solar shading

Frequently Asked Questions (FAQ)

Q: Can the width of the shade band be customized?
A: Yes. The width of the gradient band can be adjusted during manufacturing to meet specific vehicle aerodynamic curves or architectural sightline requirements.
Q: Does the tinted band affect the safety properties of the PVB?
A: Not at all. The tinted portion is co-extruded from the exact same tough PVB resin as the clear portion, ensuring uniform impact resistance across the entire glass pane.

FAQ

What aluminum alloys do you use to make motorcycle engine cases?

We mainly use high-performance aluminum alloys such as ADC12 and A356. The ADC12 is ideal for complex shapes such as side covers due to its excellent flow properties, while the A356 is the first choice for structural parts such as crankboxes that require excellent strength and elongation. We use a spectrometer to confirm the composition of each melt to ensure material stability.

How to ensure the tightness of the engine cover and prevent oil leaks?

Preventing leaks is the core standard we ensure. We control internal density through precise high or low pressure casting parameters. After casting, we perform precision CNC machining on the sealing surfaces and perform pneumatic leak tests on the oil passages and water passages to ensure zero leaks in the assembly.

How long is the delivery lead time for OEM motorcycle engine covers

For new OEM projects, the lead time from mold design to T1 sample delivery is typically 35-50 days. Once samples are approved, our capacity of 5000 tons per year allows us to adjust mass production plans to meet your specific delivery deadlines

What surface polishing options do you provide for motorcycle engine case covers?

Our process includes Shot Blasting and vibration deburring to achieve a clean, matte appearance. At the same time, we can also prepare powder coated or painted surfaces based on the aesthetic requirements of your brand.

Application Background and Use Scenario

Heat Pipe R&D and Sample Preparation


Heat pipe development requires stable and repeatable sample-level processing before entering mass production. During R&D stages, engineers need precise control over heating, degassing, and welding preparation to verify product structure and process feasibility. This equipment is designed to support such sample preparation tasks under controlled conditions.


Process Validation Before Mass Manufacturing


Before scaling up to full production lines, manufacturers often need to confirm welding parameters, heating lengths, and degassing performance. This machine provides a practical platform for process validation, helping reduce risks during later mass production deployment.


Integrated Heating and Degassing Process


The heating process is controlled by both temperature and time, allowing operators to set parameters according to different pipe diameters and material requirements. This helps maintain consistent thermal conditions during sample processing.
