Micro-Wire Encapsulation PVB for Heated & Defrosting Glass

In freezing environments, maintaining clear visibility is critical. Our Micro-Wire Encapsulation PVB is specially designed to laminate ultra-fine, electrically conductive tungsten wires between glass panes. This specialized high-flow interlayer perfectly surrounds the wires without breaking them during the autoclave process. When powered, the wires generate heat, rapidly melting snow and ice while preventing interior condensation.

Key Advantages & Benefits

  • Precision Encapsulation: High-flow resin fills microscopic gaps around the heating wires, preventing air bubbles and short circuits.
  • Rapid Defrosting: Enables the production of high-performance heated glass that clears ice and fog in minutes.
  • High Optical Clarity: Once laminated, the ultra-fine wires and the PVB film remain virtually invisible to the naked eye.
  • Thermal Shock Resistance: Designed to withstand the rapid temperature changes of heated glass without delaminating.

Versatile Applications

  • Automotive and locomotive heated windshields
  • Commercial freezer and supermarket display doors
  • Architectural skylights in heavy snowfall regions
  • Marine bridge windows and aviation cockpits

Frequently Asked Questions (FAQ)

Q: Does this PVB conduct electricity?
A: No, the PVB itself is highly dielectric (insulating). It safely encases the conductive wires, directing the heat into the glass while preventing electrical shorts.
Q: What wire diameter can be encapsulated?
A: It is optimized for micro-wires typically ranging from 15 to 50 microns in diameter, depending on the heating requirements.

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.
