1, Core Material Selection Guide
Choosing the right materials is the first step to success. We offer a variety of high-performance engineering plastics to meet the needs of different scenarios:
ABS: It has excellent comprehensive performance, good strength, toughness, and processability, and is easy to bond and spray afterwards. Commonly used for shells, functional prototypes, and consumer product components.
Nylon (PA6, PA66, PA12): Known for its excellent wear resistance, high strength, and chemical resistance. It is an ideal choice for manufacturing gears, bearings, pulleys, and industrial parts that require sustained friction.
Polyoxymethylene (POM/Delrin): "Saigang" material, with extremely high stiffness, low friction coefficient, and excellent dimensional stability. Commonly used for transmission components and precision structural parts that require precise fitting and high wear resistance.
Polycarbonate (PC): Renowned for its excellent impact resistance and transparency, while also possessing excellent insulation properties. Suitable for protective covers, windows, lenses, and electronic insulation components.
PEEK: a top-level high-performance thermoplastic with extremely high temperature resistance, chemical stability, and mechanical strength. Widely used in aerospace, medical implants, and harsh semiconductor and petrochemical environments.
PTFE (Teflon): Provides extremely low friction coefficient and excellent chemical inertness, making it the preferred choice for seals, bushings, and chemically corrosion-resistant parts.
2, Widely applicable scenarios
The application of CNC machining of plastic parts covers almost all high-tech and industrial fields:
Automotive and Transportation: Lightweight interior parts, sensor housings, insulation brackets, prototype parts for testing.
Medical and laboratory equipment: diagnostic equipment casing, surgical tool handles, disposable instrument prototypes, cleanroom components.
Consumer electronics products: Product design validation prototypes, precision brackets, connectors, small batch customized casings.
Industry and Automation: Low wear gears, guide rails, sealing gaskets, insulation fixtures, and machine protective covers.
Aerospace and Defense: Non metallic components with special requirements for weight and strength, such as drone components, communication equipment brackets, and antenna covers.
Semiconductor and food machinery: corrosion-resistant, low precipitation, and cleanroom compliant conveying components and tools.
3, Frequently Asked Questions (FAQ)
Q1: What are the main advantages of CNC machining of plastics compared to metals?
A1: Plastic is lighter in weight, with natural insulation and corrosion resistance. It has less tool wear and faster processing speed, and can achieve more complex thin-walled structures at lower costs.
Q2: What machining accuracy can you achieve?
A2: Our precision CNC machine tool can stably achieve a tolerance range of ± 0.02mm to ± 0.05mm, depending on the material properties and part structure.
Q3: How long does it take from drawing to obtaining parts?
A3: For typical parts, prototypes can be delivered within 3-7 days. The small batch production cycle depends on the quantity, and we are known for our fast response.
Q4: How to obtain a quotation?
A4: Please provide your 3D drawings (STEP, IGS, X_T format is preferred) or 2D drawings, and indicate the material, quantity, tolerance, and surface treatment requirements. We will provide a detailed quotation within 24 hours.
Q5: Is it cost-effective for small batch orders?
A5: Very cost-effective! CNC machining does not require expensive mold investment and is the perfect solution for small batch and multi variety production, which can greatly reduce your initial costs and development risks.
4, Professional surface treatment options
To enhance appearance, performance, or add special features, we offer a variety of post-processing services:
Sandblasting/frosted: Obtain a uniform matte texture, enhance tactile sensation, and mask processing textures.
Polishing/Highlighting: To achieve a mirror or highlight effect on transparent or colored plastics, commonly used for exterior parts.
Spray coating/baking paint: Provides various colors and textures (such as rubber paint), and increases weather resistance.
Screen printing/laser engraving: permanently add logos, serial numbers, or instructional text.
Electroplating (water electroplating): Achieving metallic luster (chromium, nickel, gold, etc.) on materials such as ABS, enhancing aesthetics and wear resistance.
Conductive coating: endows plastic parts with electromagnetic shielding (EMI/RFI) function.
