Silicon Carbide Plate in Mobile Phone Glass Manufacturing

Silicon Carbide Sintering Plate: The "High-Temperature Bearing Expert" in Mobile Phone Glass Manufacturing

In the mobile phone glass production chain, silicon carbide sintering plates are core components that ensure the quality of 

cover glass and display glass, providing full-process support for the two key processes of high-temperature forming and 

strengthening. 

Their core advantages are concentrated in three dimensions:

1. Excellent High-Temperature Stability to Lock in Dimensional Accuracy

Mobile phone glass needs to undergo high-temperature strengthening at 600-800℃ to improve hardness and shatter 

resistance. Silicon carbide sintering plates can be used repeatedly in this temperature range without cracking or deformation. 

They can accurately carry glass substrates, firmly locking in the preset dimensional accuracy of each piece of glass and 

fundamentally avoiding product scrapping caused by carrier deformation, thus meeting the stability requirements of 

large-scale production.

2. Low-Pollution Dense Surface to Ensure Defect-Free Appearance

After special process treatment, their surface is dense and smooth, with extremely strong chemical inertness. In a high-

temperature environment, they will neither undergo material exchange with glass nor produce dust or impurity shedding. 

This feature can completely eliminate defects such as scratches and stains on the glass surface, perfectly meeting the strict 

standards of mobile phone glass for "defect-free appearance".

3. High Thermal Conductivity Uniformity to Reduce Processing Breakage Rate

Silicon carbide materials have excellent thermal conductivity, which can quickly and evenly transfer the heat from heating 

equipment to all areas of the glass. This effectively avoids glass stress imbalance caused by local temperature differences, 

significantly reduces the breakage rate during high-temperature processing, and provides key support for the high-quality 

production of mobile phone glass.
