Ballistic-Grade Multi-Layer Security PVB

When lives are on the line, our Ballistic-Grade Multi-Layer Security PVB delivers uncompromising defense. Formulated specifically to be used in complex, multi-ply glass and polycarbonate laminates, this high-adhesion interlayer effectively absorbs massive kinetic energy from ballistic projectiles. It stretches and elongates under extreme impact, decelerating bullets and preventing deadly glass spall from injuring occupants on the safe side.

Key Advantages & Benefits

  • Kinetic Energy Absorption: Engineered with high elasticity to absorb the shockwave and kinetic force of high-velocity ammunition.
  • Multi-Material Adhesion: Bonds exceptionally well to various glass thicknesses, acrylics, and polycarbonates used in ballistic compositions.
  • Spall Reduction: Keeps the innermost layers of glass intact, preventing dangerous flying glass fragments (spall).
  • Optical Clarity: Despite being used in thick, multi-layer buildups, it maintains excellent light transmission and low optical distortion.

Versatile Applications

  • Armored VIP transport vehicles and cash-in-transit trucks
  • Military and government facility checkpoints
  • Bank teller windows and high-security currency exchanges
  • Police station and embassy glazing

Frequently Asked Questions (FAQ)

Q: Is PVB enough to make glass bulletproof?
A: PVB is a critical component, but it works in a system. True bullet-resistant glass requires alternating layers of thick glass, PVB, and sometimes polycarbonate to defeat specific ballistic threats (e.g., NIJ or EN 1063 standards).
Q: What thickness is recommended for ballistic applications?
A: 0.76mm and 1.14mm thicknesses are most commonly used between the multiple glass plies to provide the necessary energy absorption and structural binding.

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.
