Dear screen players, please pay attention! The topic we are going to talk about today is the "century problem" in the industry - why are the top spherical LED screens produced in specific areas? Do you often hear that a certain spherical screen delivers fast and has stable quality, but you don’t know the geographical password behind it? Don’t worry, this will take you to lift the mystery of the production base!

1. Three golden rules for site selection of spherical screen factories

​​1. The effect of industrial chain clustering​​
Making a spherical screen is like making a Lego, you have to get all parts suppliers. ​ ​Pearl River Delta Region​​Why can it become a major manufacturing center? A complete set of suppliers such as chip packaging, driver ICs, structural parts, etc. can be found within a radius of 50 kilometers! To give a real case: A spherical screen project only takes 45 days from design to mass production, and it depends on the suppliers in the industrial park next door.

​​2. Logistics cost control technology​​
Spherical structure transportation is a technical job, look at this set of comparative data:

​​Key reminder​​: Spherical screens with a diameter of more than 3 meters must be transported through special transportation, and you can save 30% of the freight when you are close to the port!

​​3. Concentration of technical talents​​
There are great questions hidden on the production line:

• Structural engineers need to understand surface module splicing
• Programmers must master spherical correction algorithms
• Quality inspectors need to train radian measurement techniques
  In industrial agglomeration areas, recruiting skilled technicians is three times faster than in first-tier cities!

2. Five core functional areas of the production base

​​1. Curved surface module workshop​​
There is the "heart" of the spherical screen hidden here, and the three production lines each perform their duties:
Line 1 special stamping arc frame in the morning (Error ≤0.5mm)
Assemble waterproof adhesive strips in the afternoon of Line 2 (IP65 protection standard)
Line 3 night shift to perform aging test (72-hour continuous roaster)

​​2. Sphere Calibration Laboratory​​
The temperature in this room will always be 23±1℃ and the humidity will be controlled at 45%! Do you know why? ​ ​Thermal expansion and contraction coefficient of metal frame​​It will directly affect the splicing accuracy. Last year, the temperature in a laboratory exceeded 2℃, which directly led to the rework of 200 modules!

​​3. Intelligent warehousing system​​
There are many more storage requirements for spherical screen accessories:

• The drive plate should be stored vertically to prevent deformation
• LED lamp beads must be protected from light and oxidation
• Custom shelves must be used for curved housing
  After using the WMS system, the material search time is reduced from 15 minutes to 90 seconds!

3. Guide to choosing a factory to avoid pits

​​Three soul questions that novices must ask​​

1. What is the longest distance for the supplier? (Suggested ≤80 kilometers)
2. Can you do a quick proofing? (At least there must be a 3D printing workshop)
3. Are environmentally friendly equipment complete? (VOCs processing devices must not be missing)

Last year, a customer fell into a big trap: he chose a cheap factory, but the environmental protection random inspection failed to shut down for two months, and the losses were enough to build half a new factory!

​​Five characteristics of high-quality factories​​
✅ Anti-static glue pads on the workshop floor
✅ The testing equipment has an annual calibration certificate
✅ Real-time monitoring of temperature and humidity of raw material silo
✅ Production board updates in time
✅ There is a backup generator set in the factory

Take backup power for example. This summer's power limit season, some factories rely on their own generators to save orders of tens of millions, but their competitors can only stare at me!

Personal experience in combat

After working in the display project for ten years, I discovered an interesting phenomenon:​​The site selection of spherical screen factories determines product genes​​! Coastal factories make export screens very fast, but to customize the special curve, you still have to find a production base with a R&D center. Last year, I helped the playground to renovate the spherical water screen, which was achieved by relying on the factory's own fluid laboratory to accurately cooperate with the water flow and the light.

Recently, I was following up on the smart factory renovation project and found​​Workshop digitalization degree​​Directly affects delivery speed. After the introduction of the MES system, the production cycle of spherical screens has been reduced from 20 days to 12 days, which is more competitive than price reduction! When inspecting the factory next time, it is recommended to focus on their data large screen - real-time production data is the hard power!
