I. Manufacturing Process
This product is a laptop cooling stand, featuring a hollowed-out frame with an irregularly shaped aluminum alloy structure. It needs to balance lightweight design, structural rigidity, and aesthetic appeal. The core process utilizes aluminum profile extrusion/sheet metal cutting + CNC machining + anodizing. The specific steps are as follows:
1. Raw Material Selection: 6063 aluminum alloy is used (good extrusion formability, excellent anodizing color performance, suitable for consumer-grade product appearance requirements); for those prioritizing lightweight and strength, 6061-T6 aluminum alloy can be selected, using aluminum alloy sheets or custom-shaped profile blanks.
2. Blank Forming:
◦ Sheet Metal Processing: For small-batch custom models, laser cutting/waterjet cutting is used to cut the aluminum alloy sheet into the basic outline of the stand, reducing subsequent milling allowance; thin-walled sections are bent to form the support structure, ensuring frame stability.
◦ Profile Extrusion: For mass production, a custom hollowed-out frame extrusion die is used to extrude an integrated profile blank, directly forming the hollowed-out ribs and frame of the stand, significantly reducing processing costs.
3. CNC Precision Machining:
◦ A three-axis CNC machining center is used to complete the drilling and tapping of the angle adjustment slots, anti-slip pad mounting slots, and positioning holes on the stand, as well as chamfering and deburring the edges; the support contact areas are precision milled and polished to avoid scratching the laptop casing.
◦ The angle adjustment hinge uses a boring + tapping composite process to ensure smooth rotation after assembly; mass production uses pneumatic tooling fixtures to improve clamping efficiency and machining consistency.
4. Surface Treatment:
◦ Matte Anodizing: A 10~15μm thick layer of deep space gray/blue anodizing is applied to create a uniform matte texture, improving the grip and corrosion resistance (resisting hand sweat and desktop moisture); the surface can be sandblasted to enhance anti-slip properties and visual appeal.
◦ Local Sandblasting + High Gloss: The brand logo area on the stand is high-gloss machined (roughness Ra 0.2μm or less), then anodized to create a decorative effect with contrasting light and shadow.
◦ Anti-slip treatment: Silicone anti-slip pads are attached to the laptop contact points, or micro-arc oxidation is applied to the aluminum alloy surface to increase the coefficient of friction.
5. Assembly and Inspection: Assemble the angle adjustment hinge and anti-slip silicone parts; test the load-bearing capacity of the stand (≥15kg) and the smoothness of angle adjustment; inspect the uniformity of the oxide layer and dimensional accuracy of the outer surface.
II. Manufacturing Accuracy
This stand needs to adapt to the placement requirements of laptops of different sizes while ensuring stability in use. The core accuracy indicators are as follows:
1. Dimensional Accuracy:
◦ Inner frame dimensional tolerance: ±0.5mm, suitable for 13~17 inch laptops.
◦ Angle adjustment slot dimensional tolerance: ±0.2mm, ensuring the accuracy of the hinge positioning and the locking effect after adjustment.
◦ Positioning hole position accuracy: ≤0.3mm, ensuring the secure assembly of the anti-slip pads and hinges.
◦ Overall stand height tolerance: ±0.3mm, ensuring the levelness of the laptop after placement.
2. Geometric Tolerances:
◦ Flatness of the stand support surface: ≤0.2mm/100mm, preventing the laptop from tilting when placed.
◦ Parallelism of the hinge hole centerline: ≤0.1mm, ensuring smooth angle adjustment.
◦ Parallelism of the frame diagonals: ≤0.5mm, ensuring the squareness of the stand and preventing the laptop from sliding.
3. Surface Finish:
◦ Surface roughness Ra1.6~3.2μm (after anodizing), ensuring a smooth feel and visual appeal.
◦ Support contact surface roughness Ra3.2μm, with silicone pads to enhance anti-slip performance.
◦ High-gloss decorative surface roughness Ra0.2~0.4μm, achieving a mirror-like finish.
III. Industry Applications
