1. Product structure of graphite sheet

When it comes to graphite, we are all familiar with graphite. Graphite is divided into natural graphite and synthetic graphite. Due to the difference of thickness and thermal conductivity, synthetic graphite sheet and double edge technology are used for heat sinks.

2. Process status

1. Are you still using the hole replacement process?

2. Are you still struggling with matching materials?

3. Are you still worried about low production capacity and high defect rate?

Here, I would like to share with you some other processes besides hole changing process -- [graphite sheet double-edged burger process].

3. Processing steps

4. Combination line of small hole nesting equipment

Synthetic graphite sheet for the coil material, each piece of graphite raw material is 3mm~5mm interval, quantum technology launched PLC intelligent identification, memory drawing die cutting machine, solve the industry due to the gap error of graphite sheet, lead to waste of graphite raw material, improve the material utilization rate.

The above graphite composite line equipment adopts four lamination, three punching and one cutting, which is matched with non-hole changing technology.

5. Use equipment

6. Mold design

7. Match materials

Match suitable materials according to the requirements of the product

1. Synthetic graphite sheet material T=0.025mm cutting specification: 54mm

2. Dumb black single-side adhesive tape rolling material T=0.012mm blanking specification: 62mm

3. Transparent PET double-sided adhesive (with self-releasing film) roll T=0.01mm cutting specification: 62mm

4. Transparent silicone double-layer protective film rolling material T=0.05mm blanking specification: 100mm

5. Blue silicone protective film coil T=0.05mm cutting specification: 65mm

6. Transparent and light release film coil T=0.05mm blanking specification: 68mm

7. Low-viscosity PET protective film roll T=0.1mm cutting specification: 95mm

The thickness of the auxiliary material and release force and viscosity according to the actual needs of the company to match
