Machining Properties
Acrylonitrile Butadiene Styrene (ABS) is a thermoplastic polymer material with high strength, strong toughness, and easy processing. usually, it is used in the field of electronics.
Liquid crystalline polymers (LCP) are highly crystalline, inherently flame retardant, thermotropic (melt-orienting) thermoplastics.
Nylon
Nylon was the first commercially successful synthetic thermoplastic polymer, with excellent mechanical properties, thermal, chemical and abrasion resistance.
PBT
Polybutylene terephthalate (PBT), a milky white semi-crystalline thermoplastic polyester, has high mechanical strength, and heat resistance.
Polycarbonate is a tough thermoplastic resin with flame retardancy. It has excellent impact strength, mechanical properties, and is easy to process, shape and thermoform.
The full name is Polyethylene, which is the simplest polymer organic compound and the most widely used polymer material. It has good inherent lubricity and is easy to process.
PEI
Polyetherimide (PEI for short) is an amorphous high-temperature super engineering plastic, and its cost is relatively low compared with other high-temperature materials.
Polypropylene is abbreviated as PP, which is a colorless, odorless, non-toxic, translucent solid substance. Widely used in the production of automobiles, parts, chemical containers, etc.
PPA
Polyphthalamide is a kind of synthetic resin with high hardness, high strength, good chemical resistance, and low cost. With excellent physical, thermal and electrical properties.
PPS
Polyphenylene Sulfide is a new type of high-performance thermoplastic resin, which has the advantages of high mechanical strength, high-temperature resistance, flame resistance …
PMMA(Acrylic)
PMMA (Acrylic) is a highly transparent material with excellent resistance to ultraviolet radiation, weather resistance, and outstanding strength, stiffness, and optical clarity.
PEEK
Peek is a kind of special engineering plastic with high-temperature resistance, self-lubrication, easy processing, and high mechanical strength, and other excellent properties.
HIPS
HIPS (High Impact Polystyrene) is a bright and pure amorphous plastic. It has the advantages of easy processing, rigidity, dimensional stability, and transparency.
PSU
PSU (polysulfone) is a high-temperature, amber-colored, semi-transparent plastic material. It has good radiation stability and heat resistance.
PU
PU(Polyurethane) is an extremely elastic, tear-resistant elastic material. It has excellent wear resistance, air permeability, and aging resistance.
TPE
TPE(Thermoplastic Elastomer), also known as artificial rubber or synthetic rubber. It is a kind of elastomer that has the elasticity of rubber at normal temperature.
TPU
Thermoplastic polyurethane (TPU) is an elastic material with good oil resistance, grease resistance, and wear resistance. It is also a mature environmental protection material.
The benefits of metal CNC machining servcies
Metal CNC machining services have a number of advantages over other methods of machining. One of the biggest advantages is that it is much more precise than other methods. This means that you can produce parts that are exact replicas of the originals. Another advantage is that you can produce large quantities of parts in a very short period of time.

Frequently asked questions
Thermoset plastic and thermoplastic are two different types of plastic. Thermoset plastic is a type of plastic that cannot be melted and reformed. Once it has been molded, it will retain its shape. It can be used in CNC Machining. Thermoplastic is a type of plastic that can be melted and reformed. It is often used in injection molding.
Engineering plastics offer:
- High strength and stiffness.
- Excellent heat and chemical resistance.
- Dimensional stability.
- Examples: PEEK, PPS, POM.
Yes, many thermoplastics can be recycled and reused in injection molding. However, recycled materials may have slightly reduced properties compared to virgin materials. Proper testing is recommended to ensure performance.
Flexible materials include:
- TPU (Thermoplastic Polyurethane): Elastic and abrasion-resistant.
- TPE (Thermoplastic Elastomer): Soft and rubber-like.
- Silicone: Highly flexible and heat-resistant.
