Introduction
In modern life, tri-proof lights have become essential equipment in industrial lighting. Their production process must balance material strength, protective performance, and intelligent design to meet the demands of various lighting environments. So, how are tri-proof lights manufactured? The following content will introduce the main manufacturing process of tri-proof lights and the core advantages of Toppo.
Material Selection and Preprocessing

The shells of tri-proof lights are primarily made from two types of materials: aluminum alloy and engineering plastics (PC/PMMA). Aluminum alloy is formed through die-casting, while engineering plastics are manufactured using injection molding, offering corrosion resistance and impact resistance. Toppo's tri-proof lights use high-strength aluminum materials and high-temperature resistant PC/PMMA, ensuring stable operation in extreme temperatures ranging from -40°C to +50°C. They also pass the IK10 impact resistance certification, suitable for high-vibration environments such as factories and tunnels.
Structural Design and Mold Development
Structural design needs to consider both functionality (such as heat sink fins, sealing grooves) and installation adaptability (track, suspension, etc.). Toppo's Tubar series incorporates fin-type heat sinks within aluminum shells and ensures IP69K sealing through ultrasonic welding. Additionally, the shell is equipped with stainless steel track buckles for easy installation.

Electronic Component Assembly

LED chips, driver power supplies, and circuit boards are soldered together using automated equipment and fitted into the lamp body. The driver power supply must adapt to a wide voltage range to ensure stable power supply. The assembly process must avoid static electricity and contamination to guarantee the long lifespan of the lamp.
Sealing and Protection Treatment
The lamp body joints and end caps undergo multi-layer sealing treatment, commonly using silicone gaskets and ultrasonic welding. After sealing, airtightness is verified through air pressure testing. Toppo's lamps feature a quick-release end cap design, supporting multiple lamps in series, simplifying the wiring process.

Performance Testing and Certification

The finished product must pass tests for luminous flux, light distribution, color temperature, color rendering index, voltage, current, ambient temperature, internal junction temperature, and water and dust resistance to ensure stability in various environments.
Packaging and Transportation
During packaging, scratch-resistant materials are used to prevent transportation damage. Toppo supports OEM/ODM services, providing multi-core connection modules to meet the needs of large projects.

Conclusion
The above content provides a detailed introduction to the complete production process of tri-proof lights, which covers materials, structure, assembly, testing, and packaging and transportation. Each step requires precise control. Only through a rigorous production process can tri-proof lights maintain stability in various harsh environments.
