Low-Flow PVB for Fabric & Mesh Encapsulation

Unleash limitless architectural creativity with our Low-Flow PVB for Fabric & Mesh Encapsulation. Standard PVB becomes highly fluid during the autoclave heating process, which can crush, warp, or wash out the dyes of delicate materials placed inside the glass. Our specialized low-flow formula bonds at lower pressures and maintains its viscosity, securely encapsulating silk, metal mesh, dried botanicals, or printed PET films without destroying their intricate details.

Key Advantages & Benefits

  • Material Preservation: Prevents the shifting, tearing, or crushing of delicate decorative inserts during the lamination process.
  • Bubble-Free Sealing: Specifically designed to fill the micro-voids of woven fabrics and wire meshes, ensuring perfect optical clarity without trapped air.
  • Structural Safety: Transforms decorative art glass into fully certified safety glass suitable for architectural partitions and doors.
  • Dye & Color Protection: Low-temperature processing ensures the vivid colors of printed inserts or silks do not bleed or fade.

Versatile Applications

  • High-end hotel lobbies and restaurant partitions
  • Custom decorative doors and closet panels
  • Elevator cab interiors with encapsulated metal mesh
  • Bespoke artistic stained glass alternatives

Frequently Asked Questions (FAQ)

Q: Can any fabric be laminated inside the glass?
A: Most synthetic and natural fabrics can be used, provided they are completely dry and free of oils or sizing chemicals. We recommend conducting a small lamination test before mass production.
Q: How thick should the PVB be for mesh encapsulation?
A: The PVB thickness must exceed the thickness of the mesh or fabric. Typically, two layers of 0.76mm (one on each side of the fabric) are used to ensure the insert is fully embedded.

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.
