2.28mm Ultra-Thick Load-Bearing Structural PVB

For high-risk, extreme load-bearing applications like walkable glass floors and transparent swimming pool bottoms, standard interlayers are insufficient. Our 2.28mm Ultra-Thick Load-Bearing Structural PVB provides massive shear strength and impact absorption. By eliminating the need to stack multiple layers of 0.76mm PVB, this monolithic ultra-thick film reduces lamination defects, prevents delamination under heavy flexural stress, and ensures total safety for structural glazing.

Key Advantages & Benefits

  • Extreme Load Capacity: Engineered to support heavy, continuous loads (like human traffic or tons of water pressure).
  • Monolithic Reliability: A single 2.28mm extrusion eliminates the micro-bubbles and delamination risks associated with stacking thinner PVB layers.
  • Post-Breakage Rigidity: If a heavy multi-ply glass panel fractures, this ultra-thick film firmly locks the shards in place, preventing catastrophic collapse.
  • Processing Efficiency: Saves immense labor time in the cleanroom by requiring only one layer of film layout per glass gap.

Versatile Applications

  • Walkable glass floors and cantilevered glass balconies
  • Transparent swimming pool walls and bottoms
  • Glass stair treads and landings
  • Zoo and large aquarium enclosure panels

Frequently Asked Questions (FAQ)

Q: Why not just use three layers of 0.76mm PVB?
A: Stacking multiple layers traps air between the PVB films, drastically increasing the risk of bubbles during autoclaving. A single 2.28mm layer ensures a flawless, bubble-free laminate with superior structural integrity.
Q: Does the extreme thickness reduce optical clarity?
A: We use a highly purified, ultra-clear resin formulation for our thickest films, ensuring that even at 2.28mm, the glass retains pristine, distortion-free transparency.

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.
