Seal cutting
Seals play a key role in industry, providing tight connections and preventing leakage of liquids or gases, which protects equipment from damage and improves operational efficiency. Their application spans a wide range of industries, from automotive, aerospace to the chemical industry, where they are used in a variety of components such as engines, pumps and valves, ensuring system reliability and safety.

Functions and use of seals
Seals are used in all hydraulic installations – both water and sewerage and heating, as well as those used in the construction of machinery or in mechanical vehicles. Without seals, it is also difficult to imagine the efficient operation of gas installations, since their function is to prevent liquids or gases from escaping from the installation.
Why is the care of seals so important?
Lack of seals or malfunctioning seals in the installation can lead to leaking or leaking air outside. This, in turn, entails a risk of failure – such as flooding of the engine or other vehicle or machine components; serious financial losses – high water bills or operation of the installation; and finally, there is a real danger – a leaky gas installation can lead to a build-up and explosion of gas.
Cutting seals with an oscillating knife – what is it?
The oscillating knife is a modern type of head mounted for CNC machines. It is used to cut materials that are characterized by low density. These include: rubber, also reinforced rubber, fabrics, foams, cardboard.The oscillating knife, guided by a numerically controlled machine, guarantees the highest precision in maintaining the shape and dimensions of the seals.
The technology makes it possible to make seals in both standard sizes and shapes, as well as fitting to installations with unusual shapes.The oscillating knife greatly expands the production possibilities – it works in parallel with the milling spindle. In this way, the components are cut using a cutter, and then their final layer is cut with a knife blade.
What materials do we cut seals from?
For the production of seals, we mainly use silicone plates available in different color versions and with different hardnesses.
Silicone is characterized by excellent resistance to high and low temperatures, which makes the seals of this material retain their properties over a wide range of temperatures. In addition, silicone seals are resistant to UV radiation and ozone, which guarantees their long service life even in harsh environmental conditions. Silicone is also flexible and resistant to many chemicals, making it an ideal choice for applications in the food, medical, aerospace and automotive industries. Thanks to these properties, silicone seals provide reliable sealing in a wide range of applications.
Why do we bet on these products?
The choice of a silicone seal over other materials is justified due to silicone’s exceptional temperature resistance, which provides a stable seal in applications that require working under extreme thermal conditions. In addition, silicone is characterized by excellent flexibility and resistance to aging, UV radiation and ozone, which ensures the seal’s long-term durability, even in demanding environments. In addition, its chemical resistance to many substances makes silicone seals an ideal choice in applications that require contact with a variety of chemicals.
Cutting rubber seals with an oscillating knife – benefits
Cutting seals with an oscillating knife offers precise cutting thanks to the oscillating movement of the blade, which minimizes the risk of material damage and ensures accurate patterning of the seal shape. Due to the small vibrations of the tool, this process is more controlled and convenient compared to traditional methods, which increases the efficiency and comfort of work. In addition, the use of an oscillating knife allows for fast and efficient cutting of hard sealing materials, which translates into saving time and reducing waste.
Send us your design and we will take care of cutting seals to size!
For the production of seals, we need their design, recorded in a vector file, including in .dxf or .dwg formats. We can also scan the seal supplied by the customer and on the basis of it we can create a model, according to which we will program the production process at the next stage.
Based on the model of the seal, we program the paths that the blade will take during the cutting of the material. CNC machines guarantee the perfect repeatability of the manufactured objects. Therefore, when mass ordering, you can be sure that each of the parts will retain the dimensions and shapes specified in the design. In the case of seals, this is crucial, because even minor deviations from the norm could cause the installation to leak. We guarantee professional service.
