ABS
ABS is a copolymer consisting of three monomers: acrylonitrile, butadiene, and styrene. The mix of these monomers gives ABS a distinct set of characteristics, such as high impact strength, satisfactory heat resistance, and outstanding dimensional stability.
PMMA
PMMA, also referred to as acrylic, is a durable and transparent material that is resistant to UV radiation and weathering. Thanks to its appealing aesthetics, it can be readily colored, molded, and utilized in a wide range of construction applications.
PE
Polyethylene (PE) is a widely utilized thermoplastic polymer renowned for its outstanding properties. This lightweight, resilient, and adaptable material finds extensive application in diverse fields, owing to its ease of processing into various shapes and sizes.
Nylon
During machining, nylon, a synthetic thermoplastic polymer, necessitates careful attention to prevent overheating, as this can result in problems such as melting, distortion, or harm to the material.
PEEK
PEEK (Polyetheretherketone) is a distinctive engineering plastic renowned for its exceptional qualities, such as resistance to high temperatures, self-lubricating capabilities, ease of fabrication, and superior mechanical strength.
PC
Polycarbonate is a robust and durable plastic that possesses flame-resistant and antioxidant characteristics. It exhibits superior impact resistance, clarity, and mechanical attributes.
PP
PP (Polypropylene) is noted for its exceptional chemical resistance, a high melting temperature, and its low density. When machining PP with a CNC machine, it is essential to employ a sharp tool with a large rake angle and a slow cutting speed. These precautions ensure that the material does not overheat and melt.
PET
Polyethylene terephthalate (PET), a thermoplastic material, is a suitable choice for CNC milling and turning processes because of its excellent machinability and adaptability. With appropriate tooling and cutting settings, PET can be readily shaped and molded, rendering it perfect for producing prototypes, bespoke components, and containers via CNC machining.
POM
POM(Polyoxymethylene) is a thermoplastic material known for its exceptional stiffness, low friction coefficient, ease of machining, and outstanding dimensional stability. However, working with POM can be difficult because of its high melting temperature and tendency to chip or crack if the cutting parameters are not precisely managed.
PVC
PVC is robust, long-lasting, and resistant to chemicals, weather conditions, and flame. However, machining it can generate hazardous dust and fumes that may pose a risk to workers’ safety. To ensure the safety of workers, it is essential to utilize appropriate safety gear and ventilation during the process.
