There are various types of gaskets commonly used in valves. According to the material of the gaskets, they can be divided into three categories: non-metal, metal and composite.
1. Non-metallic gaskets mainly include rubber sheets and asbestos rubber sheets, polytetrafluoroethylene sheets and glass fiber PTFE sheets. The CNC Oscillating Cutter is mainly used for cutting non-metallic gaskets. The process of cutting will be explained in detail in the following.
2. Metal gaskets (rings) are made of metal gaskets such as trapezoidal, elliptical, diamond, triangular and toothed. It is suitable for mediums with flammable, explosive, high temperature and high pressure, good sealing performance and high stability.
3. Composite gasket refers to a gasket made of metal and non-metal materials. It has the properties of high temperature and high pressure of metal materials, and the flexibility and elasticity of non-metallic materials.
Different types of gasket cutting machines
Today, we mainly discuss the cutting method of non-metallic gaskets. According to different factors, we can help you choose the right CNC cutting equipment.
5 ways to process traditional gaskets:
First, the plate cutting gasket;
In the process of cutting Teflon plate and asbestos board, because the size of the plate is relatively large, we can use the turning plate or the molding plate to directly round the gasket, or cut into squares or round blocks, and then turn it into a lathe. The gasket can also be made into a die for a thinner gasket and directly punched out under the press;
Second, the mold stamping gasket:
Presses are used in the cutting of gaskets and are suitable for mass production of standard gaskets, but there are two serious problems with this type of processing.
First of all, the way the mold is processed is not flexible enough. If the size and style of the gasket change, it is necessary to re-make a mold. The accumulation of the mold not only occupies the place, but also costs a lot of money. Sealing gaskets like small batches are very unsuitable for stamping.
Secondly, the waste of materials, good punch workers will give you the means to save materials and reduce waste, but how many workers can there be? The number of pieces determines his income. Many times he doesn’t waste material when you waste it. Anyway, I gave you the amount. The cost problem has nothing to do with me. How do you say this? It’s hard to control, you can’t stare at it every day, it’s too tired.
Third, turning processing gasket:
This processing method is suitable for PTFE solid rods and tetrafluoroethylene molded tubes.
PTFE pipe turning gasket has good surface flatness, large output, precise precision and less waste. It is also a relatively economical processing method. The disadvantage of processing is that each type of gasket needs a matching pipe mold;
The PTFE rod is a solid rod. Generally, the lathe for the gasket is small, which saves electricity, and many companies have adopted automatic lathes, which are convenient for processing. This processing method is generally suitable for bulk or small gaskets. Large gaskets are not primarily considered for material savings.
Fourth, molded gasket
Direct molding using a mold, such a gasket generally has a certain thickness requirement, such as requiring a thickness greater than 3 mm, the gasket is directly molded and sintered, the density is good, the pressure resistance is good, but the processing speed is slow, and the mold processing is simple and suitable. Large quantities of gaskets are produced.
Five, wound gasket
For metal-wound composite gaskets, this is a gasket made of V-shaped or W-shaped stainless steel belt and PTFE, spirally wound, and spot-welded at the beginning. It is suitable for high temperature and high pressure steam, oil, gas, solvent and other production occasions.
The above five methods are the processing methods of traditional gaskets. Each cutting method has its advantages and has its shortcomings.
Two problems with these five traditional processing methods:
1. High dependence on the technical level of workers;
The workers in the sealing industry are aging, the recruitment of mature operators is becoming more and more difficult, the labor costs and management costs are getting higher and higher, the product quality is unstable, and the utilization rate of materials cannot be controlled.
2. The production process requires the production of a large number of molds;
The processing method is not flexible enough, and it is suitable for the production of single-size and large-size gaskets. Can not meet the processing of sample production, shaped parts and non-standard specifications of the gasket. Moreover, the mold production will cause the gasket to have a long production cycle and cannot be delivered in time.
So, is there a more flexible processing method to help customers in the sealing industry reduce production costs, ensure product quality, and meet different types of order production?
The answer is: yes!
With the continuous development of numerical control technology, more and more industries choose to use intelligent cutting equipment instead of workers. CNC oscillating knife cutting machine is a kind of CNC machining equipment widely used in the sealing industry. It adopts advanced oscillating knife cutting technology and can choose different tools according to materials. It can meet the cutting of non-metallic gaskets such as asbestos sheet, asbestos rubber sheet, graphite composite sheet, rubber and PTFE.
AMOR CNC gasket cutting machine adopts reasonable and advanced mechanical structure design and professional sealing industry intelligent processing software, which enables AMOR sealing industry cutting machine to cut sealing gaskets of different sizes and shapes with high precision, high speed and more stable.
Cutting the gasket with CNC oscillating knife cutter has 4 advantages:
1. More flexible; the gasket automatic cutting machine does not need a mold, only need to import the processing data (PLT, DXF, AI format) into the system, can cut, and can modify the size and shape of the gasket.
2. Saving materials; automatic nesting software can complete typesetting quickly and accurately, without manual discharge. After a lot of testing, using automatic cutting machine saves more than 10% of materials.
3. Guarantee product quality; CNC cutting is more precise and meets the sealing requirements of sealing gaskets.
4. Reduce the dependence of production on labor; the operation of CNC gasket cutting machine is very simple, the requirements of many workers are low, and the problem of high labor cost and difficulty in recruitment is solved.
If you are a producer in the gasket industry, you are facing difficulties in recruiting skilled workers, low productivity, low material utilization, low volume orders, high product reject rates, and long lead times. Then, you can look at the CNC oscillating knife cutting machine. It can help you solve these problems and make your production super easy.
