We uphold the commitment to precision manufacturing and excellent quality, relying on advanced materials science and manufacturing technology to provide tailor-made high-quality solutions for global customers. CNC Plastic Machining Parts is one of our products. The processing flow of CNC Plastic Machining Parts will be introduced below.

1. CNC plastic processing parts refer to parts obtained by precise processing of various plastic materials through computer numerical control technology. This type of product has a wide range of applications in modern manufacturing, including automobiles, aerospace, electronic equipment, medical devices and other industries. Plastic materials have become an important choice in many fields due to their advantages such as light weight, corrosion resistance and flexible molding. Combined with the high precision and automation advantages of CNC processing, we are able to manufacture plastic parts with precise dimensions and stable performance.
During CNC machining, the computer controls the motion trajectory of the machine tool through a preset CNC program, and performs cutting, milling, drilling and other process operations on the material. Compared with traditional manual operations, CNC machining can greatly improve machining accuracy and production efficiency, and is particularly suitable for the manufacture of parts with complex shapes and high precision requirements.

2. Process flow of CNC plastic parts

During the production process of CNC plastic parts, Ningbo Haishu Dongxiang Precision Hardware Co., Ltd. strictly follows the following process flow to ensure the accuracy and quality of each part.

The first step in CNC plastic machining is the selection of materials. Different plastic materials have their own characteristics and applicable scenarios. We usually choose suitable materials according to the specific needs of customers. Common CNC machining plastic materials include:

ABS (Acrylonitrile-Butadiene-Styrene Copolymer): This material has good impact resistance and processability, and is widely used in automotive parts, electronic housings and other fields.

Nylon (PA): Nylon materials have excellent wear resistance and mechanical strength, and are suitable for high-load parts such as gears and bearings.

Polyoxymethylene (POM): POM is suitable for high-precision parts due to its hardness and rigidity, and is often used in medical devices and electronic components.

Polypropylene (PP): PP is lightweight and chemically resistant and is often used in parts for tanks and chemical equipment.
After selecting the right plastic material, Ningbo Haishu Dongxiang Precision Hardware Co., Ltd. will cut and fix the material to ensure that it can be accurately placed on the CNC machine for processing.
Ningbo Haishu Dongxiang Precision Hardware Co., Ltd. will use CAD (computer-aided design) software to draw a 3D model of the plastic part according to the customer's product design requirements. This process includes detailed dimensioning and shape design to ensure that every detail of the part can be accurately reproduced. After the design is completed, the engineer will import the 3D model into CAM (computer-aided manufacturing) software to generate the corresponding CNC code. These codes include parameter settings such as the movement trajectory, speed, feed rate, etc. of the machine tool during the processing.
Programming is one of the core steps of the entire CNC processing process. Accurate program writing directly affects the final quality and processing efficiency of the part. Our experienced technical team can design the optimal processing path for complex parts to ensure smooth production.
After programming is completed, the core stage of processing officially begins. At this stage, the machine tool performs various process operations on the plastic material according to the preset CNC program. The specific processing processes mainly include the following.
Milling: CNC milling machines remove materials through high-speed rotating tools, which are suitable for processing complex shapes such as planes, slots, and concave and convex surfaces.
Turning: On CNC lathes, the material rotates while the tool moves radially or axially, mainly used to manufacture cylindrical parts such as shafts, threads, etc.
Drilling: The drilling process in CNC processing can achieve high-precision hole processing, which is suitable for plastic parts that require multiple holes.
Engraving: For the processing needs of surface patterns or logos, Ningbo Haishu Dongxiang Precision Hardware Co., Ltd. can achieve fine graphics and text engraving through engraving technology.
During the processing process, the machine tool accurately controls the position and feed speed of the tool through a computer to ensure that each cut can accurately cut the material. In order to ensure the surface finish and dimensional accuracy of plastic parts, we will adjust the tool speed and feed speed according to the characteristics of the material to reduce thermal deformation and tool wear during processing.
Cooling and lubrication: In CNC plastic processing, temperature control is particularly important. Since plastic materials are relatively soft, long-term cutting processing can easily lead to an increase in the surface temperature of the material, which in turn causes problems such as melting and deformation. Ningbo Haishu Dongxiang Precision Hardware Co., Ltd. usually uses special coolants or air cooling systems to reduce the surface temperature of the material and keep its shape stable. At the same time, proper lubrication can reduce the friction between the tool and the material, extend the tool life, and improve processing efficiency.

Ningbo Haishu Dongxiang Precision Hardware Co., Ltd. is able to provide customers with precision plastic parts processing services through advanced CNC processing technology. Our CNC plastic parts have been widely used in many fields due to their high precision, flexibility and excellent material properties. In the future, we will continue to uphold the spirit of innovation, continuously optimize the processing technology, and provide global customers with better products and services.
