Glass Fiber Sizing Machine

Precision Craftsmanship for Electronic Glass

Electronic glass fabric goes into circuit boards. The quality needs are very high. The glass filaments are very fine. They break easily. Tension control must be exact. This glass fiber sizing machine is made for electronic glass, industrial filters, and high-performance composites. We use a micro-tension control system. The goal is to protect each fine filament while adding size. This ensures the final product is top grade. Our customers often ask how we achieve such fine control. We tell them it is all in the micro-tension tech. This is the Glass Fiber Sizing Machine for precision work.

Glass fiber size can corrode machines. So we use 316L stainless steel for all key parts. The size box and guide parts can handle high heat and acids. The squeeze roller uses imported high-hardness rubber. Its hardness is Shore 85±3. The pressure can be set from 0 to 25 kN. The size temperature control is very tight at ±0.5℃. The guide rollers have a nano-ceramic coating. The surface is ultra-smooth at just Ra 0.08 μm. The friction is below 0.08. This is the best way to cut wear on fine glass filaments. This Glass Fiber Sizing Machine is built for the most delicate work.

The micro-tension control is the heart of this machine. It keeps yarn tension in a very tight range of 3 to 15 cN. The change is under ±1.0 cN. One client makes electronic glass for export. They trust our micro-tension system. We use a double-dip and double-squeeze process. This helps the size get into every filament. The drying system is very efficient. The drying temperature is controlled to ±2℃. The size pickup is even at over 96%. The machine has an auto beam change and a quality tracking system. The beam is very straight, with an error of just 0.08mm over 1 meter. The winding density error is under 1.5%. This machine meets ISO 11111-1:2016 and CE standards. It also meets IPC-4412B for electronic-grade glass. At Jiangsu Global Jingtian, we help you reach the highest standards. This Glass Fiber Sizing Machine is your ticket to the high-end electronic materials market.
