Plastic CNC Machining for Various Industries

Aerospace
3-Axis CNC Milling

3-axis CNC milling is an economic and efficient solution that is ideal for machining parts with simple geometries and flat surfaces.

Automotive
4-Axis CNC Milling

4-axis CNC milling adds rotary capability, allowing more complex cutting on multiple angles without relocating the part, improving accuracy and efficiency.

Industrial Equipment
5-Axis CNC Milling

5-axis CNC milling offers outstanding versatility for machining parts with curved surfaces or complex geometries, and ensures excellent precision and finish.

Advantages of CNC Milling

CNC milling is a highly versatile and precise manufacturing method, offering efficiency, repeatability, and quality for prototyping and full production.

High Precision and Consistency

CNC milling machines achieve ±0.005mm tolerances, ensuring parts meet design specs. Automated control ensures consistent accuracy in batches, ideal for aerospace, medical, and electronics industries.

Wide Material Compatibility

CNC milling supports various materials, including metal,plastic,ceramic and composite materials, allowing selection based on mechanical properties, weight, corrosion resistance, or cost.

Fast Turnaround Times

CNC milling is highly efficient for rapid prototyping or small-batch production, delivering functional parts within days with optimized tool paths, multi-axis machines, and minimal manual intervention.

Excellent Surface Finish

CNC milling offers smoother surfaces and sharp edges, often eliminating the need for post-processing, which is especially advantageous for tight-assembly parts and customer-facing components.

Cost-Effective for Mid to Low Volumes

For custom, complex, or low-to-medium volume production, CNC milling offers great value without the need for costly molds or tooling, making it perfect for both one-offs and recurring projects.

Scalability from Prototypes to Production

Start with a single prototype and scale seamlessly. Our CNC milling capabilities support full production without compromising quality, even as your volume grows.

CNC Milling Surface Finishing Options

Surface finishing is crucial in CNC milling, improving part appearance, durability, and performance. Solnit provides various CNC milling finishing options to meet functional and aesthetic needs across industries.

Finishing Option Process Description Typical Applications / Benefits
Anodizing (Type II/III) Electrochemical oxidation for aluminum. Type II for color, Type III for hardness. Corrosion resistance, color customization, surface hardening (Type III).
Powder Coating Dry powder applied electrostatically and cured to form a tough polymer layer. Durable wear-resistant coating, aesthetic color and texture.
Bead Blasting Abrasive blasting with glass or ceramic beads to create matte texture. Smooth satin finish, tool mark removal, pre-treatment for coating.
Polishing Mechanical or manual buffing to create a glossy or mirror-like surface. Decorative finish, pre-plating preparation, consumer or luxury parts.
Electroplating / Nickel Plating Metal layer deposited via electrochemical process (e.g., nickel, chrome). Improved conductivity, corrosion/wear resistance, used in electronics/tools.
Passivation Chemical removal of free iron from stainless steel surfaces. Enhances corrosion resistance, especially for medical and food-grade parts.
Brushing Abrasive brushing to create directional grain/satin texture. Aesthetic enhancement, hides minor defects, popular in consumer products.
Black Oxide Chemical conversion coating for steel, creating a dark oxide layer. Mild corrosion protection, anti-glare, used in shafts, tooling, fasteners.
