Introduction
Black Delrin CNC Milling Parts are precision parts made of high-performance thermoplastic engineering plastic Black Delrin through advanced computer numerical control (CNC) milling technology. These parts are made of a single Black Delrin material and are widely used in medical equipment, automotive parts, electronic components, sports equipment, and other fields due to their excellent mechanical properties, wear resistance, corrosion resistance, and biocompatibility.
Features
Excellent dimensional stability
Black Delrin CNC Milling Parts have excellent dimensional stability, mainly due to the high rigidity and low shrinkage characteristics of Black Delrin material. Black Delrin's elastic modulus is as high as 3000MPa, much higher than general plastic materials, making the parts deform very little when subjected to force. At the same time, Black Delrin's shrinkage is extremely low, usually between 0.1%-0.2%, much lower than other thermoplastics (such as ABS's shrinkage is usually between 0.4%-0.7%). Under extreme temperature changes (-40°C to 120°C), the size change of Black Delrin parts is only within ±0.01 mm, ensuring its stability and reliability during long-term use.
Excellent corrosion resistance
The Black Delrin material used in Black Delrin CNC Milling Parts has high density and chemical stability. Its density is usually around 1.4g/cm³, higher than most plastics. Its molecular structure is tight and not easily penetrated by chemicals. After Black Delrin is immersed in a 30% hydrochloric acid solution for 24 hours, its mass loss rate is only 0.1%, which is much lower than other plastic materials (such as ABS, which can reach a mass loss rate of more than 5% under the same conditions).
Extremely high safety
Thanks to the non-toxicity and low irritation of the Black Delrin material itself, Black Delrin parts will not cause allergic reactions or rejection reactions in the manufacture of parts that directly contact the human body, such as medical equipment and surgical tools, and it can ensure the safety and health of patients. In addition, Black Delrin's flame retardancy and low smoke toxicity are also significant advantages. Its limiting oxygen index (LOI) is as high as 24%, much higher than that of ordinary plastics. It can effectively prevent the spread of fire in emergencies such as fire, reduce the release of toxic gases, and protect personnel safety.
Application
Mechanical parts
Due to its hardness, high wear resistance, and self-lubrication, Black Delrin is often used to manufacture various mechanical parts, such as gears, bearings, sliding and rotating machinery, etc. These parts need to withstand large loads and friction during operation, and the excellent performance of Black Delrin ensures that they can operate stably for a long time, reducing the frequency of maintenance and replacement.
Medical equipment
Black Delrin CNC Milling Parts has good biocompatibility and corrosion resistance, making it a material that can manufacture medical equipment parts. In addition, due to its easy cleaning and disinfection characteristics, it is also particularly suitable for medical environments that require frequent cleaning and disinfection.
Electronic appliances
Due to its good electrical insulation and arc resistance, Black Delrin is often used to manufacture electronic product housings, insulating parts, etc. In addition, its high-temperature resistance also enables it to maintain stable electrical performance in high-temperature environments, thereby ensuring the normal operation of electronic equipment.
Sports equipment
In the field of sports equipment, Black Delrin is also used for its wear resistance, impact resistance, and self-lubrication. Parts made of Black Delrin can be seen in sports equipment such as skis, skateboards, and bicycles. These components not only improve the durability of sports equipment but also enhance the user experience of athletes.
