Plastic Cutting

One of the main characteristics of plastic materials is their ability to be molded into a finished component without the need for further work. Complex shapes, holes and undercut features can be molded into the part using molding tools and techniques. At Shamesh Azadi, all plastic cutting services and machining and turning of various types of Teflon sheets and bars are performed at reasonable prices. Contact the sales department for prices.
Why Plastic Cutting

The molding tools and forming equipment used in the various plastic molding processes are always handmade. Their production often takes weeks and months to produce the desired result. Where a plastic component is specified and the numbers used are not large, machining becomes more economical.

Not all plastic materials can be machined. The stiffer the plastic, the easier it is to machine. More flexible and softer plastics are not suitable for machining. Polyethylenes do not contain any toxic or impacting substances that change the properties of food and are completely hygienic. In the Azadi ingot collection, it is produced from first-class raw materials without any impurities. You can also use it with confidence in restaurants, food processing centers, medical and household uses. Cutting of Teflon types in the form of bars, pipes and bushings, sheets and plates is possible.
What points should be observed in plastic cutting?

Cutting tools used in the machining of all materials rely on the strength of the component being cut.

In the case of plastics and Teflon, machining is more for rigid and hard materials, such as fiber-reinforced thermoset plastics, glass-reinforced nylons, acrylic or PEEK, which have good relative hardness. When the cutter tries to cut the part, the less rigid plastic deforms and bends, which makes it difficult to achieve fine dimensional tolerances.

Teflon can be cut in various sizes and these orders are accepted according to the wishes and orders of customers.
Plastic Cutting Methods
CNC Machining

If the part to be cut has a complex shape, its specifications can be programmed into the computer. A CNC machining center can be used to produce repetitive parts. The multiple interchangeable cutters commonly used in CNC machines allow for the machining of complex and varied components.
Turning

If the shape to be obtained is round, a simple turning operation can be used. Specialized equipment attached to the lathe can increase the performance capabilities of the lathe.
Milling

This cutting method can vary from simple milling to profiling and CNC milling. As with turning, either adding to the milling machine or using a more complex milling machine can increase the ability of the milling machine to create more complex shapes.
Sawing

This cutting method is usually used to simply remove sections of plastic material from a stock of bars for further processing by other machining operations.
Die Cutting

In certain cases, the use of a die cutting plastic material can produce a simple component. This process is limited to sheet materials. A male and female die is used to extrude a predetermined shape. This process can be a manual process or an automated one using a special machine.
Hot Knife Cutting

Softer and harder types of plastic can be cut using a hot knife to cut the plastic. An electrically heated wire or blade melts the plastic locally. This type of process is commonly used to cut foam and expanded polystyrene (EPS) blocks.
Punching

Special shapes can be cut on metal-type punch presses. Like a CNC machine, they are always computer-controlled and equipped with several tools. This process is limited to thinner thermoplastic and thermoset sheet.
Waterjet Cutting

This process is used to cut fiber-reinforced thermoset components that would otherwise be difficult to cut by other processes. The hard reinforcing layers in this material defy trimming with conventional knives and cutting equipment. The narrow cutting path and fast feed without dust or chips are advantages.
Laser Cutting

This process can be used to cut and profile certain types of acrylic and other plastics, although they are not thermosets. The process uses an industrial laser to melt the plastic, often followed by computer-controlled profiles.
Ultrasonic Cutting

Some thinner plastics can be cut using ultrasonic machining. The high frequency generated by the ultrasonics in the tool has the effect of locally melting the plastic being cut. Again, integrated with computerized specification control, this process lends itself to high-speed automated production lines.
