Process advantages
High precision and consistency
CNC machining uses a numerical control system to manage the tool path, allowing for micron-level machining accuracy and making it ideal for creating products with tight tolerances. Furthermore, batch processing ensures product consistency and drastically reduces defect rates.
Strong processing flexibility
No need to open mold; it can be processed swiftly in accordance with the 3D and CAD files, making it ideal for proofing, small batch production, and manufacturing parts with complicated structures and irregular geometric shapes.
Wide Material Compatibility
CNC machining can be used on a wide range of engineered plastics to meet various strength, temperature, wear, and other performance criteria.
Shortened Delivery Time
Compared to injection molding, CNC machining saves mold opening time, allows for speedier manufacturing, and saves clients significant development cycles.
Material Choosing
Commonly used materials for CNC machining plastic parts include:
ABS
Has good dimensional stability and processing performance, making it popular in consumer electronic housings, prototype proofing, and other applications.
PC (polycarbonate)
Strong strength, good transparency; ideal for optical components, safety coverings, and other uses.
POM (Saigang)
Good self-lubrication, high wear resistance, ideal for precision mechanical parts such gears and sliding parts.
PEEK
Excellent high temperature and chemical corrosion resistance; widely utilized in high-end industries such as aviation and medicine.
Nylon (nylon)
Has excellent strength and hardness, making it ideal for mechanical structural parts, fixed seats, and other applications.
PMMA (acrylic)
High transparency, smooth surface after processing, ideal for display components and appearance samples.
Surface Treatment Process
Plastic parts after CNC machining can be subjected to a variety of surface treatments to improve their appearance or functional performance:
Grinding and Polishing
Remove burrs and knife marks, increase smoothness;
01
Sandblasting
Increases surface roughness or creates a matte look.
02
Spray Painting
Meets color appearance criteria while also being waterproof and scratch-resistant.
03
Silk Screen Printing/Pad Printing
Apply a logo or design to the surface of plastic items;
04
UV Coating
Improves surface toughness and anti-aging capabilities, commonly used in electronic housings.
05
Laser engraving produces permanent markings that are difficult to remove.
Application Scenarios
Medical Equipment
CNC processed plastic parts are frequently utilized in medical equioment housings, functional components, connectors, and other parts, as they exceed industry standards for sterility, corrosion resistance, and high precision. We can process medical-grade materials like PEEK and PC to assure the safety, reliability, and stability.
Automotive Industry
Used for structural part testing and small batch manufacture, including vehicle-mounted electronic devices, interior buckles, sensor brackets, and so on. CNC processing can respond swiftly to iterations during the design verification stage, allowing customers to shorten their development cycles.
Consumer Electronics
CNC processed plastic parts are used in mobile phone accessories, earphone structural components, and smart wearable gadgets to meet the dual needs of brand customers for product appearance and structural strength. They have high precision and good surface effects.
Industrial Automation and Robotics
Used for robot housings, brackets, slide rails, insulation components, and so on. High-strength technical plastics, such as POM and nylon, may provide good wear resistance and structural support performance when CNC machined, and are frequently employed in factory automation systems.
Smart Home and IoT Devices
Smart terminal devices, including smart door locks, thermostats, security cameras, and gateway control boxes, have exceptionally high structural correctness and appearance texture criteria. CNC machining plastic parts enables rapid prototype and multi-batch flexible manufacturing, allowing clients to accelerate the entire process from concept verification to market launch.
The aviation and UAV industries
Applicable to the production of components such as structural parts, tiny connectors, support systems, and so on that must be lightweight, heat resistant, and strong. PEEK, PC, and high-strength nylon are all commonly utilized materials.
Quality Control System
We constantly follow the production principle of "quality first" and have built a comprehensive quality control method for CNC machining plastic parts:
- Incoming material inspection: All raw materials come from high-quality vendors with material certification.
- Process control: Create a first-piece confirmation, inspection, and sampling procedure to guarantee that the structure and dimension fit the criteria of the designs.
- High-precision inspection equipment includes a three-coordinate measuring machine (CMM), a height gauge, a caliper, and a thread gauge.
- Appearance inspection: Strictly control color, finish, surface flaws, and so forth.
To protect against friction or pressure damage during transportation, all final products will be appropriately wrapped with dust bags, pearl cotton, and foam cartons.
