Interlocking Felt Cutting Machine
As PET felt acoustic panels, polyester fiber acoustic materials, and decorative felts see increasingly widespread use in architectural acoustics, interior design, office spaces, and commercial venues, felt products are evolving from traditional standard sheets toward irregular shapes, modular designs, custom configurations, and interlocking structures.
For manufacturers of felt tiles and acoustic panels, a key challenge in production is how to ensure consistent cutting dimensions while simultaneously boosting efficiency, minimizing material waste, and rapidly meeting diverse customer customization needs.
CNC oscillating-knife felt cutting machines utilize digital controls to drive an oscillating blade in high-speed reciprocating cuts along pre-set paths, enabling the direct processing of flexible materials such as PET felt, polyester fiber acoustic panels, and decorative felt. When integrated with CAD/CAM design and automatic nesting software, these machines can also produce a wide range of interlocking felt tiles, custom-shaped acoustic panels, and complex acoustic decorative components.
Detailed introduction
As the use of sound-absorbing panels, PET felt, decorative felt, and various acoustic materials grows across interior renovations, office spaces, commercial buildings, and public venues, manufacturers face increasingly demanding requirements for precision cutting—including irregular shapes, modular tiles, and complex contours. Traditional manual cutting methods are not only inefficient but also prone to issues such as dimensional inaccuracies, uneven edges, and material waste.
To address the processing needs for felt tiles, sound-absorbing panels, and other flexible acoustic materials, oscillating knife cutting machines utilize digital CNC control and high-speed oscillating knife technology. These systems can automatically execute contour cutting, irregular shape cutting, hole punching, and the fabrication of interlocking structures based on CAD designs. For products requiring the assembly of multiple felt modules, optimized nesting and interlocking structural designs can further enhance material utilization and reduce the need for manual processing steps.
What is an interlocking felt cutting machine?
The interlocking felt cutting machine is a digital cutting system designed for felt tiles, PET acoustic panels, and acoustic decorative materials. Its core capability goes beyond simply cutting felt into fixed dimensions; instead, it utilizes digital nesting to arrange multiple cutting modules based on product structure and assembly methods, producing components that can be interconnected, combined, or interlocked.
For instance, when manufacturing wall-mounted or ceiling-suspended acoustic panels, artistic felt shapes, and modular acoustic decor, designers can create various geometric profiles using CAD software, while a CNC system controls an oscillating knife to cut the material along the specified paths.

Why do felt tiles require oscillating knife cutting?
Felt is a flexible material characterized by a fibrous structure and a certain degree of elasticity. When processed using conventional mechanical cutters, the results are easily affected by the material’s thickness, hardness, and fiber structure.
An oscillating knife cuts into the material through high-speed vertical vibration, enabling rapid, continuous cutting. Compared to manual cutting with scissors or standard tools, digital oscillating knife cutting offers greater path stability and is well-suited for the batch processing of complex shapes.
For the production of felt tiles, the equipment can directly read digital graphic files—such as DXF, AI, and CAD formats—and automatically execute cutting based on preset dimensions and paths.
This means that production staff do not need to create physical templates for every specification; instead, they can simply modify the digital files to produce felt products in various sizes and shapes.
How does an interlocking structure improve the processing efficiency of felt tiles?
Traditional felt tiles typically require individual measuring, marking, and cutting. When dealing with a large number of tiles in various shapes, manual processing often leads to inconsistent dimensions.
The advantage of digitally cut interlocking tiles is that the connection structure for each module can be determined during the design phase.
Once cut according to digital files, the various modules can be assembled directly.
This approach is particularly well-suited for sound-absorbing panel systems that require rapid on-site installation. Manufacturers can produce standardized modules in advance, which are then assembled on-site according to numbering or layout plans, thereby minimizing the need for on-site cutting.
How does digital cutting reduce waste of felt materials?
For the production of felt tiles and acoustic panels, material utilization directly impacts product costs.
When cutting manually, operators typically need to arrange pieces individually according to templates, which often results in significant offcuts. In contrast, CNC cutting machines utilize nesting software to arrange shapes of various specifications—either automatically or through manual optimization.
Once the software optimizes the layout based on shape dimensions and spacing, the cutting paths are transmitted to the CNC system.
For bulk orders, this digital nesting approach helps maximize material utilization and minimizes material waste caused by inefficient manual layout planning.
Typical production process for felt tiles:
The processing of felt tiles using an oscillating knife cutting machine typically follows this workflow:
Design drawings → CAD file processing → Material placement → Vacuum hold-down → Automatic nesting → Tool parameter setup → CNC oscillating knife cutting → Dimensional inspection → Module sorting → Packaging or on-site installation.
During the CAD design phase, interlocking structures for the various modules can be defined in advance, allowing the finished products to be assembled directly after production.
For mass production, multiple product shapes can be nested together to minimize frequent material changes and repetitive operations.
Automation configuration in the production of felt acoustic panels:
If the enterprise has a high volume of orders, automation features can be further configured.
For example:
An automatic feeding system can reduce the manual labor involved in material handling.
A vacuum hold-down system helps secure felt sheets, minimizing material movement during cutting.
A CCD vision positioning system is suitable for materials featuring printed patterns or markings, or those requiring precise alignment.
Automatic nesting software optimizes layouts based on product designs, thereby improving material utilization.
An automatic tool-changing system is ideal for production scenarios that require switching between different tools during processing.
Configurations can be tailored to production scale, material type, and product structure, rather than applying the same automation system to every application.
For felt tiles, PET acoustic panels, and custom acoustic decor products, production requirements are shifting from simple sheet cutting toward digital design, complex contour machining, and modular assembly.
Interlocking felt cutting machines utilizing oscillating knife technology can directly translate CAD designs into actual cutting paths, enabling the processing of felt modules in various shapes and sizes without the need for extensive traditional tooling. Through digital nesting, automated cutting, and versatile tool configurations, enterprises can further enhance production flexibility, dimensional consistency, and material utilization rates.
For manufacturers producing felt tiles, PET acoustic panels, irregularly shaped acoustic panels, and custom acoustic decor, oscillating knife CNC cutting solutions offer a digital alternative to traditional manual cutting. Final equipment configuration should be determined through sample testing and selection based on specific factors such as material type, thickness, product dimensions, interlocking structures, and daily output requirements.
