Nylon 6 Nylon 66 Machine Parts

Nylon is the common name of polyamide, is one of the world's most common engineering plastics, with excellent strength, toughness and wear resistance, but also easy to process, can be used as a variety of machine parts.Nylon processed parts have good overall performance, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubricating, and low coefficient of friction, a certain degree of flame retardancy, easy processing, nylon processed parts suitable for filling with glass fiber and other fillers to enhance the modification, improve performance and expand the range of applications, followed by its overload protection function, when the torque is too large, the gear itself is damaged, power transmission interrupted so as to protect the lower device or life safety, reduce losses.PA gears

Properties and grades of machined nylon (PA)

Nylon (PA) is known for its high crystallinity, producing strong, strain-resistant components. In addition, the use of nylon reduces the need for extensive lubrication, reduces noise, and eliminates wear, corrosion and theft problems.PA PA6 processing part,

Nylon 6 and Nylon 6/6 nylons are available in two common grades that are noteworthy for their properties and uses. They can be used interchangeably in a variety of applications, but have some property differences.Machining Nylon Polyamide

Nylon 6 Milling PA6 6 Nylon is typically produced in two forms: a high-strength type for textile applications and a high-strength type for industrial use. It is usually formed into filament yarns and staple fibers. Most often, this nylon is used for tire cord, parachute, rope or industrial cordage. Similar to nylon 6, nylon 6/6 has many industrial uses, from thin-walled parts to large, thick-walled bearings. It is also an excellent candidate for metal replacement.

Advantages of nylon:PA6 Screw Machine Parts

1, high mechanical strength, good toughness, high tensile and compressive strength.

Its tensile strength is higher than metal, compressive strength and metal equivalent, but the stiffness is not as good as metal. Tensile strength is close to yield strength, more than twice that of ABS. It has a strong ability to absorb shock and stress vibration, and its impact strength is much higher than that of ordinary plastics and better than acetal resin.

2、Good fatigue resistance.

Parts made of nylon can be alternately bent, but still maintain its original mechanical strength properties. pa can usually be used in places where fatigue is often very obvious, such as escalator handrails, plastic rims of new bicycles, etc.

3. High softening point and heat resistance

(Like nylon 46, high crystalline nylon has high heat deflection temperature and can be used for a long time at 150 degrees C. When PA66 is reinforced with glass fiber, the heat deflection temperature can be over 250 degrees C.)

4, smooth surface, small coefficient of friction, wear-resistant.

When used as moving mechanical parts, it has self-lubrication, low noise, and can be used without lubrication if the friction is not too great. If you really want a lubricant to reduce friction or help heat dissipation, you can choose water, oil, grease, etc. Therefore, it has a long service life as a transmission part.

5、Corrosion resistance

Very resistant to alkali and most salt solutions, resistant to weak acids, motor oil and gasoline, resistant to aromatics and common solvents, inert to aromatics However, it is not resistant to strong acids and oxidizers. Resistant to gasoline, grease, alcohol and weak bump erosion, with excellent anti-aging ability. It can be used as packaging materials for lubricants and fuels.

6、Self-extinguishing, tasteless, non-toxic, weather-resistant, resistant to biological erosion, excellent anti-bacterial and anti-mildew properties.

7、Excellent electrical properties.

Due to its high volume resistivity, nylon is not easy to decompose under high pressure. In dry environment, it can be used as an industrial frequency insulating material. Even in high humidity conditions, it can maintain good electrical insulation.

8. Light weight, easy to dye and easy to mold.

Its melt viscosity is low and its flow speed is fast. High freezing point, easy injection molding, fast molding speed, short molding cycle, high production efficiency.

Disadvantages of nylon (PA)

1, low water absorption, low dimensional stability. Uneven wall thickness will lead to deformation and distortion of mechanical parts. High requirements for machining equipment. Not easy to resist strong acids and strong oxidizing agents. Can not be used as acid-resistant materials.

2、Poor cold resistance.

3、Poor antistatic property.

4、Heat resistance is poor.

Nylon applications

Nylon material is an engineering thermoplastic, easy to process, can be used as a variety of mechanical final parts. Today, it is widely used in a variety of applications, such as clothing, rubber-like automotive tire reinforcement, rope and line, as well as many injection-molded parts for vehicles and machinery. Bearings, bushings, wheels, rollers, etc.
