The Mica Tube Customized Processes The Following Steps
 

Confirm specifications

Customers need to provide detailed specifications such as length, inner diameter, outer diameter, thickness, and material of mica tubes.

Material selection

Select the suitable mica material according to the customer’s requirements and application. Usually, we need to send you the temperature resistance demand. We will suggest muscovite mica and phlogopite mica.

Glue mica paper

After confirming the mica tube size and material, our mica sheet glue machine will make the glued mica paper. The mica paper width is 1010mm, and the regular mica tube length is 1m.

Mica Tube Mold

The mica tubes are made on the mold; the mold’s outer diameter fits the mica tube’s inner diameter. We have a stock of different sizes of molds. When you have a new demand, please tell us, and we will check the stock, then offer the price and the finishing time

Make Mica Tube & Bake

Roll the glued mica paper on the tube mold tightly, and knead the mica tube to the tight structure. Then, pull out the mold from the mica tube and put the mica tube back in the oven.

Quality Inspection & Packing

Inspect the mica tubes’ quality, including testing of appearance quality, dimensional accuracy, bending strength, and other indicators. Then, the mica tube will be packed safely for transportation.

 

 
 
Manufacturing Process of Mica Tube

Material Selection

The process begins by choosing high-quality mica sheets. These sheets are selected for their durability and performance in harsh conditions.

 

High Temperature Resistance Mica Tube

Bonding with Resin

To enhance strength, the mica sheets are bonded with resin-based substances like silicone. This step ensures the tubes are both robust and functional.

Mica Tubes

Shaping and Cutting

The mica is precisely cut and shaped into tubes. These tubes can be customized in terms of length, diameter, and thickness to meet specific application needs.

Electrical Mica Tube

Testing and Quality Control

Each mica tube undergoes rigorous testing. This ensures they meet high-performance standards for insulation, temperature resistance, and mechanical strength.
