1. What is felt?
Felt, a common industrial tool, is mostly made of wool, and is also made of cow hair or fiber, which is processed and bonded. The main characteristics are elasticity, which can be used as a material for shockproof, sealing, padding and elastic wire needle cloth base felt. It is used in various industrial machinery-anti-vibration, oil-containing lubrication, friction resistance and other industries.
1.1 Felt can be classified from the following three aspects:
By material
Natural fiber felt: mainly wool, with high elasticity and hygroscopicity.
Synthetic fiber felt: such as polyester fiber, wear-resistant and chemical corrosion-resistant.
By process
Needle punched felt: The density is enhanced by needle punching process, which is suitable for sound insulation and filtering scenarios.
Punching felt: The shape can be customized and used for precision parts or pads.
By function
Filter felt: used for oil filtration and air purification.
Buffer/soundproof felt: shock-absorbing and noise-reducing materials in automobiles and home appliances.
2. Application industries and fields of felt

4. How to choose a suitable <Truster CNC> Felt Cutting Machine?
4.1 Clarify material adaptability
Material type and thickness
CNC Felt Cutting Machine is mainly used for non-metallic materials (such as leather, felt, textiles, EVA foam, etc.), and it is necessary to confirm whether the equipment is suitable for the target material according to its own processing needs. The cutting thickness is usually recommended to be within 50mm. Some models of <Truster CNC> felt cutting machines support precision cutting of thicker materials (need to be verified in combination with equipment power and cutter head performance).
Special functional requirements
If processing lightweight materials (such as thin felt), attention should be paid to the suction function of the conveyor belt to prevent material displacement from affecting accuracy.
For scenes with high precision requirements (such as instrument gaskets and complex patterns), a CNC Felt Cutting Machine model with an error of ≤0.1mm should be selected.
4.2 Clarify the working area of the CNC Felt Cutting Machine
Standard size range of CNC Felt Cutting Machine
Common work surface widths are 1.6 meters to 2.5 meters, and lengths cover 2.5 meters to 3.5 meters, for example:
1.3 meters × 2.5 meters, 1.7 meters × 3 meters and other basic specifications.
Some models support wider formats, such as 2.1m x 3m, which is suitable for batch cutting of large-sized felt or composite materials.
Customized options – CNC Felt Cutting Machine
Users can choose to lengthen or widen the CNC Felt Cutting Machine according to their needs, for example:
Lengthen to 3.5m (such as 1.5m x 3.5m or other sizes) to meet the continuous cutting needs of extra-long materials.
For special scenarios, the CNC Felt Cutting Machine with a double gantry structure can be customized to improve the processing efficiency of complex patterns.
