3. CNC machining Delrin parts advantages
Delrin plastic has many unique advantages which make Delrin as one of the most used plastic materials for rapid prototyping. Below are Delrin material properties.
High Hardness
The hardness of Delrin is usually around 88 HRM. Delrin’s molecular chains are tightly arranged and have excellent rigidity and wear resistance. Therefore, it is suitable for the manufacture of mechanical parts, gears, bearing rings, and other parts that require high hardness.
Excellent rigidity
Delrin has a compact molecular structure and exhibits excellent rigidity. It has good ability to resist deformation when subjected to force. This makes it suitable for the manufacture of mechanical parts that require high precision and structural stability.
Low coefficient of friction
Delrin’s low coefficient of friction helps reduce friction between parts and improve mechanical efficiency. It is widely used in bearings, slides, and other parts that require reduced friction and improved mechanical efficiency.
Excellent wear resistance
The hardness of Delrin gives it excellent abrasion resistance, making it suitable for long periods of high-friction environments. Commonly used in gears, bearings, and other parts that require high wear resistance.
Good chemical resistance
Delrin shows good stability to some solvents and chemicals and is not easy to corrode. Suitable for some special environments, such as parts in the chemical industry.
Dimensional stability
Delrin shows good dimensional stability over a wide temperature range and is not easily affected by temperature changes. It is suitable for precision mechanical parts that require high dimensional accuracy.
Good insulating properties
Delrin has good insulating properties and is suitable for electronic and electrical applications. It is widely used in the manufacture of electrical components, insulating parts, etc.
High fatigue resistance
High fatigue resistance allows Delrin plastic to excel in long-term use and frequent movement of mechanical parts. It is suitable for parts that need to withstand frequent movement and deformation.
High abrasion resistance
High abrasion resistance enables Delrin to maintain a long life in high-friction environments. Suitable for parts in high friction environments such as gears and bearings.
Low Moisture Absorption
Low moisture absorption means that Delrin is relatively insensitive to changes in humidity. It is suitable for parts in humid environments where stable performance needs to be maintained.
Good weather ability
Good weather ability makes Delrin relatively insensitive to sunlight and climate change. Suitable for parts in outdoor environments, such as automotive parts.
High tensile strength
High tensile strength allows Delrin to withstand large tensile forces. It is suitable for structural parts that require high tensile strength.
Oilability
Good resistance to some lubricants, which aids operation in lubricated environments. Suitable for mechanical parts that need to operate in a lubricated environment.
High melting point
A high melting point allows Delrin to maintain good performance in high-temperature environments. Suitable for applications requiring high-temperature stability, such as engine parts.
Dimensional Accuracy
CNC machining Delrin performs well in the manufacture of precision parts and helps maintain dimensional accuracy. Ideal for engineering parts that require high precision.
Low moisture absorption
Low hygroscopicity means that it is relatively insensitive to changes in humidity, which helps maintain stable performance in different environments. Ideal for parts that require stable performance in humid environments.
