The gasket is a kind of sealing part used in machinery, ships, automobiles, and other fields.
Classified by material type: Gaskets are divided into metal gaskets, non-metal gaskets, and metal and non-metal composite gaskets.
Metal gaskets-copper gaskets, stainless steel gaskets, iron gaskets, aluminum gaskets, etc.
Non-metallic gaskets-asbestos gaskets, non-asbestos gaskets, paper gaskets, rubber gaskets, etc.
Metal and non-metal composite gaskets-graphite composite gaskets, rubber composite gaskets, built-in 304/316 stainless steel with a thickness of 0.1-0.2mm.

Gasket manufacturing process
Two processes for producing gaskets-stamping and cutting.
The traditional stamping method can be used to produce gaskets with a single shape, standard size, and large demand. It is necessary to make a mold according to the size of the gasket first, and then use the equipment to stamp. The advantage of the stamping mode is that standardized gaskets can be produced quickly and in batches. However, it takes a long time to make a mold, and one type of mold can only produce a gasket of one specification, so the disadvantage of the stamping method is that it is inflexible and cannot meet the processing of small batches, multiple styles, and different sizes of gaskets.
So how to produce small batches and multiple styles of gaskets more flexibly and efficiently?
CNC Oscillating Knife Cutting Machine——Using pneumatic and electric oscillating tools, using the blade to rotate and vibrate to cut various types of gaskets, cutting is pollution-free, environmentally friendly, and accurate in size. It can cut gaskets of different sizes and shapes at will, and the processing method is flexible.
Advantages of cutting gaskets with AMOR oscillating knife cutting machine:
1. Different tools can be configured to meet various types of gasket cutting-the vibration knife cutting machine supports a variety of tool combinations such as electric oscillating tools, pneumatic oscillating tools, and milling cutters, and can meet various non-metallic gaskets and composite reinforced gaskets Cutting, such as non-asbestos gaskets, silicone gaskets, rubber gaskets, paper gaskets, cork gaskets, PTFE gaskets, graphite composite gaskets (built-in stainless steel) and other types of gasket cutting.
2. Using intelligent nesting software to improve material utilization-AMOR CNC gasket cutting machine is equipped with intelligent nesting software, with 30+ gasket drawings, customers only need to change the size to get the cutting graphics, No CAD drawing is required. The software supports secondary nesting of remaining materials, which improves the utilization rate of materials.
3. Flexible processing methods, no mold required-fully meets the processing needs of various types of gaskets and variable sizes. Rapid production can be achieved without the need to make molds, which shortens the production cycle and reduces the cost of mold production;
4. Reduce the dependence of gasket production on workers-AMOR CNC gasket cutting machine is easy to operate, no programming, automatic cutting, only need to learn 2-3 days to operate in quantity, reducing the degree of dependence on skilled workers in gasket production, To ensure the stability of production.

3 factors affecting the cutting of sealing gaskets by oscillating knife cutting machine
There is no doubt that the oscillating knife cutting machine is very suitable for non-metallic gasket cutting machines. However, in order to obtain a perfect gasket cutting effect, you must pay attention to the following three factors:
1. Choose the right tool for different gasket materials.
The material, thickness, and hardness of the gasket will affect the choice of the tool.
For gaskets with small thickness and low hardness, you can choose an electric oscillating knife cutter to give full play to the cutting advantages of speed, such as rubber gaskets with a thickness of less than 5mm, silicone foam gaskets, etc.
For gaskets with small thickness but high hardness, it is recommended to choose a more powerful pneumatic oscillating knife cutting tool, which can well overcome the difficulty of cutting caused by high material hardness, such as 2mmPFFE gaskets, 5mm non-asbestos gaskets, 10mm silicone gaskets Sheets and graphite composite gaskets, etc.
For gaskets with large thickness and high hardness, it is recommended to choose milling tools, such as 5mm epoxy resin plate gaskets, 5mm PTFE gaskets, etc.
2. If you choose a pneumatic oscillating tool, you must ensure stable air pressure.
Combining the choices of the above three tools, the pneumatic oscillating tool is the absolute main force for cutting non-metallic gaskets. When choosing the pneumatic oscillating tool to cut the gasket, if you want to achieve the best cutting section and cutting speed, then you must ensure the cutting When the air pressure is greater than 0.7MPA, this can effectively reduce the damage of the blade and ensure a good cutting effect, especially when cutting hard PTFE, non-asbestos gaskets and graphite composite gaskets.

3. Choose the right blade.
We need to choose the right blade according to the different gaskets to be cut. Only in this way can we achieve the perfect cutting of the gasket and ensure the continued use of the blade. There are three factors for choosing a blade: blade shape, blade length, and blade thickness. Through many years of customer experience, AMOR CNC provides customers with a set of scientific blades for different gaskets, which not only meets the requirements of small hole cutting in the gasket industry According to the needs of various gaskets, a variety of unique knives have been developed to provide customers with a good cutting experience.
AMOR CNC has a wealth of experience in gasket cutting and provides you with high-quality CNC gasket cutting machines. The machine is driven by a Japanese Mitsubishi servo motor and rack transmission.
