Key Advantages & Benefits

  • Ultimate Portability: Folds into a compact, briefcase-like form factor with an ergonomic handle for effortless transportation.
  • Optimized Solar Angle: Integrated adjustable aluminum kickstands allow you to tilt the panel precisely toward the sun for maximum efficiency.
  • Plug-and-Play Connectivity: Comes equipped with standard MC4 connectors and multiple adapter cables, compatible with most major portable power stations and solar generators.
  • Durable Protection: The solar cells are protected by a highly transparent, scratch-resistant ETFE lamination and enclosed in a splash-proof Oxford cloth casing.

Versatile Applications

  • Camping, overlanding, and RVing
  • Emergency backup power for home use
  • Mobile work sites and outdoor photography
  • Tailgating and outdoor events

Frequently Asked Questions (FAQ)

  • Is this foldable panel waterproof? The solar panel surface (ETFE) is highly waterproof. The fabric casing is splash-resistant (IP65 rated), meaning it can withstand light rain, but it should not be fully submerged in water.
  • Does it include a charge controller? This specific model is just the solar panel designed to plug into portable power stations (which have built-in controllers). A separate PWM or MPPT charge controller is required if charging standard 12V/24V deep-cycle batteries.

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.
