PuKong Prototype: Rapid Prototyping Process for Robot Enclosures

At PuKong Prototype, we specialize in high-quality rapid prototyping for robot enclosures, ensuring precision, durability, and aesthetic excellence. Our streamlined process integrates advanced manufacturing techniques, including CNC machining, 3D printing, silicone molding, and post-processing treatments, to deliver functional prototypes quickly and efficiently. Below is a detailed breakdown of our production workflow:

1. Design & Programming

Before production begins, our engineers analyze the 3D CAD model of the robot enclosure to determine the optimal manufacturing method. Depending on the complexity, material, and required tolerances, we select between CNC machining, 3D printing, or silicone molding.

• CNC Programming: For metal or high-precision plastic parts, our team generates G-code using CAM software (e.g., Mastercam or Fusion 360) to guide CNC machines.

• 3D Printing Slicing: For resin or thermoplastic parts, we prepare the model in Ultimaker Cura or Formlabs PreForm, optimizing support structures and layer thickness.

2. Manufacturing Process

(A) CNC Machining

For aluminum, steel, or engineering plastics (e.g., ABS, POM), we use 3-axis, 5-axis CNC milling, or lathe machining.

• Steps:

• Raw material clamping → Toolpath execution → Precision cutting → Deburring

• Tolerance: Achieves ±0.05mm for critical dimensions.

(B) 3D Printing

For rapid iterations or complex geometries, we employ:

• SLA (Stereolithography): Smooth, high-detail resin parts.

• SLS (Selective Laser Sintering): Durable nylon components.

• FDM (Fused Deposition Modeling): Cost-effective thermoplastic prototypes.

(C) Silicone Molding (Vacuum Casting)

For small-batch production (10–50 units), we create silicone molds from a master pattern (3D printed or CNC-machined).

• Process:

• Master model preparation → Silicone mold pouring → Urethane/resin casting → Demolding & trimming.

3. Post-Processing & Finishing

(A) Assembly & Adjustment

• Components are dry-fitted to ensure proper alignment.

• Fasteners (screws, adhesives) are applied, and moving parts are tested for smooth operation.

(B) Surface Treatment

• Painting: Automotive-grade spray painting with masking for multi-color designs.

• Anodizing (for Aluminum): Enhances corrosion resistance (e.g., Matte Black, Gold, Clear).

• Electroplating: Chrome, nickel, or gold plating for metallic aesthetics.

• Laser Engraving: Adds logos, serial numbers, or instructional markings.

4. Quality Inspection

Each part undergoes rigorous checks:

• Dimensional accuracy (CMM or calipers).

• Surface finish (no cracks, bubbles, or uneven coatings).

• Functional testing (fit, durability, electrical insulation if applicable).

5. Packaging & Shipping

• Anti-scratch wrapping: Bubble/Foam wrap or foam inserts prevent transit damage.

• Custom packaging: Cardboard boxes or wooden crates for bulk orders.

• Tracking & Logistics:

• Each shipment is assigned a unique tracking number (e.g., DHL/UPS/FedEx).

• Customers receive real-time updates via email/SMS until delivery.
