Why are the requirements for silicone in the lotus lantern molds higher?
Lotus lanterns usually have multiple layers of overlapping petals, clear venation patterns, and curved surface transition structures. Common mold silicone rubber is prone to the following problems:
· The details are not clearly replicated, and the patterns are blurry.
· During demolding, it tears, and the mold has a short lifespan.
· The shrinkage rate is unstable, resulting in size deviations of the finished products.
Therefore, industrial-grade lotus lantern molds require silicone to possess three core properties: high fluidity, low shrinkage rate, and high tear strength.
What can our industrial-grade silicone molds do?
0.1mm detail reproduction capability
Low viscosity and good leveling property enable it to perfectly replicate minute structures such as the venation of lotus leaves and the edges of petals, without the need for a second mold modification.
The tear resistance strength has been increased by more than 30%.
The edges remain intact even after multiple demoulding processes. A single set of molds can complete the production of over 800 lotus lanterns, reducing the mold opening cost.
Shrinkage rate < 0.1%
High dimensional stability, suitable for use in conjunction with various lamp body materials such as ABS, resin, and gypsum.
Temperature range: -50℃ to 250℃
Suitable for various processing environments such as vacuum injection molding and thermosetting resins, providing more reliable industrial production.
Real customer case: A transformation of a lighting factory in Zhejiang Province
"Previously, we used regular silicone. Every time we made 20 lamps, we had to change the mold. The edge of the petals always lacked material. After switching to your industrial-grade silicone, one set of molds could produce 200 lotus lamps continuously, and the patterns remained clear, and the demolding process was also very smooth." -- Manager Zhang, a certain LED handicraft factory in Zhejiang Province
How to choose the right silicone model for your process?
We offer three common hardness levels (A5 / 10 / 20), which can be matched according to the complexity of the structure of the lantern, the expected production volume, and the injection method (pouring or brushing). If you are unsure which one to choose, you can send us the 3D drawing or physical photo of the lantern, and we will recommend a solution based on the specific structure.
