Description
In industrial design, engineering plastics are often used to customize plastic parts to verify your ideas. If your idea includes hardware materials and plastic materials, do you need to distribute them to two different suppliers, and finally assemble them yourself? At H&G Precision, you don’t need to. All our plastic hardware materials can be CNC processed. We have long-term provided customers with a series of services from processing to surface treatment to assembly, so that your design can not only ensure performance, but also be attractive in appearance. client.
What surface treatments can be done on CNC processed plastic?
We can not only do surface treatment for hardware products, plastic products can also be customized with surface treatments such as: spray painting, silk screen, baking paint, powder spraying, electroplating, laser engraving, polished transparent, fumigated transparent, dyeing, etc. If you need small batch customized processing , we can also provide customized packaging services according to your needs, saving you procurement time and costs.
But what you need to know: How to choose the right plastic material when CNC processing plastic?
1.ABS
ABS is one of the most common thermoplastic materials with good mechanical properties, excellent impact strength, high heat resistance and good machinability.
ABS’s low density makes it ideal for lightweight applications. CNC machined ABS parts are often used as prototypes before injection molding for mass production.
Material properties:
Typical density: 1.00-1.05 g/cm3
2.Nylon
Nylon, also known as polyamide (PA), is a thermoplastic frequently used in engineering applications because of its excellent mechanical properties, good impact strength, and high chemical and abrasion resistance. But it absorbs water and moisture easily.
Nylon 6 and nylon 66 are the most commonly used grades in CNC machining.
Material properties:
Typical density: 1.14 g/cm3
3.Polycarbonate
Polycarbonate is a thermoplastic with high toughness, good machining properties and excellent impact strength (better than ABS). It can be tinted but is usually optically clear, making it ideal for a wide range of applications including fluid installations or automotive glazing.
Material properties:
Typical density: 1.20-1.22 g/cm3
4.POM
POM, commonly known by the trade name Delrin, is the engineering thermoplastic with the highest machinability among plastics.
POM (Delrin) is usually the best choice when CNC machining plastic parts that require high precision, high stiffness, low friction, excellent high temperature dimensional stability and extremely low water absorption.
Material properties:
Typical density: 1.40-1.42 g/cm3
5.PTFE
PTFE, commonly known as Teflon, is an engineering thermoplastic with excellent chemical and heat resistance and the lowest coefficient of friction of any known solid.
Polytetrafluoroethylene (Teflon) is one of the few plastics that can withstand operating temperatures above 200°C and is an excellent electrical insulator. However, it has purely mechanical properties and is often used as a lining or insert in components.
Material properties:
Typical density: 2.2 g/cm3
6.HDPE
High-density polyethylene (HDPE) is a thermoplastic with a high strength-to-weight ratio, high impact strength and good weather resistance.
HDPE is a lightweight thermoplastic suitable for outdoor use and pipes. Like ABS, it is often used to create prototypes prior to injection molding.
Material properties:
Typical density: 0.93-0.97 g/cm 3
7.PEEK
PEEK is a high-performance engineering thermoplastic with excellent mechanical properties, thermal stability over a very wide temperature range, and excellent resistance to most chemicals.
PEEK is often used to replace metal parts due to its high strength-to-weight ratio. Medical grades are also available, making PEEK suitable for biomedical applications as well.
Material properties:
Typical density: 1.32 g/cm 3
