CNC Machining Plastic Parts---Unique advantages and application

Unique advantages

Cost-effectiveness:

Plastics have unique physical and mechanical properties, and more importantly, the cost of plastic CNC machining is usually lower than that of metals and alloys even in mass production, making plastics a cost-effective material choice.

Corrosion resistance:

Especially in areas with high humidity, corrosion resistance is a major advantage of plastics. For applications that require long-term use in harsh conditions, plastic products processed by CNC machining are a reliable choice.

Fast production:

Plastics are compatible with CNC machines and can quickly produce parts with high precision and precise tolerances. For example, when processing nylon materials or POM, we can achieve a surface roughness of Ra 1.6. This means that plastic CNC machining can provide an efficient solution in the manufacture of parts that require complex geometries and tight tolerances.

Variety of material selection

There are many types of materials in precision CNC plastic processing, each with its own unique advantages and applicable scenarios.

POM : 

This material has high hardness, rigidity, and wear resistance. It has a narrow processing temperature range and good acid and alkali stability, but poor thermal stability. It is often used to make wear-reducing and wear-resistant parts, such as transmission belts, gears, spring sheets, and various parts in chemical equipment. Because of its wear resistance and corrosion resistance, it can also replace many non-ferrous metals and is used in automobiles, machine tools, instruments, and even electric kettles and faucets.

Nylon:

This is a thermoplastic resin with excellent comprehensive properties, such as strength, heat resistance, wear resistance, corrosion resistance, and self-lubricating effect. Therefore, it is widely used in places such as bearings, gears, and transmission belts that require durability and wear resistance. In new energy vehicles, because it can adapt to high-voltage environments, some high-voltage connectors are also replaced with nylon.

PEEK: 

This material is heat-resistant and corrosion-resistant, and is particularly suitable for parts that require high strength and high performance, such as implants for aerospace and medical use. It is also used to make various mechanical components, such as structural parts and connectors. In the medical field, PEEK can be used to make surgical instruments and implants.

PA6: 

As a type of nylon, it has good mechanical properties, heat resistance, and corrosion resistance. This material is widely used in fibers, engineering plastics, and electronic and electrical components.Each material has its own characteristics and uses, and the choice should be based on actual needs. For example, if you need high wear resistance, choose nylon or PEEK; if you need heat resistance, choose PEEK or acrylic.

CNC machining plastic parts - diversity of applications

Aerospace field:

In the aerospace industry, CNC plastic machining is used to manufacture lightweight, durable, and heat-resistant parts, such as aircraft interior components (seats, luggage compartments, lampshades, control knobs), insulation components, and lightweight structural parts. These parts need to be highly precise and durable to withstand extreme flight conditions. CNC machining provides the necessary precision and repeatability to ensure consistency and high performance of parts even in mass production.

Medical industry:

In the medical field, CNC plastic machining is used to manufacture precision medical devices such as prostheses. These devices need to be highly precise, biocompatible, and customized to the specific needs of the patient. CNC machining allows for the mass production of prosthetic parts with intricate details and high precision while maintaining cost-effectiveness and production efficiency.

Other Industry Applications:

CNC plastic processing is also widely used in many industries such as automobiles, automation, consumer goods, electronics, industrial equipment, new energy, medical devices, robots, semiconductors, etc. JST has produced many similar CNC machined plastic bicycle parts, and our production capacity is 500,000 PCS per month. JST has produced many CNC turned plastic parts, and the materials include nylon, acrylic, PP, PTFE and PEEK. The diameters of these custom precision CNC machined plastic parts range from 5mm to 300mm.
