ABS Engineering Plastic
ABS Engineering Plastic is a very common general-purpose choice in machining engineering plastics: considering cost, processing efficiency, and appearance, it is suitable for structural parts, appearance parts, and functional verification prototypes. When you want parts to have a certain rigidity, are easy to post-process, and aim for small batches/rapid iteration, ABS is often the most cost-effective solution.
Material description

Order suggestion: If there are exterior/assembly surfaces, please define "key surfaces" in the remarks; ABS is more sensitive to sharp corner stress and thin-walled large planar surfaces, so it is recommended to add fillets and reinforcing ribs; If repeated screw assembly and disassembly are required, it is recommended to evaluate inserts/structural optimization and provide 2D annotations (hole position/tolerance/reference).

Wall thickness and deformation control
- Wall thickness and deformation control: Avoid ultra-thin large flat surfaces; Reinforcement or increased thickness may be added if necessary to reduce processing stress and the risk of deformation during use.
- Internal Corner Fillets and Stress Concentration: Try to make internal corners rounded (recommended R0.5+) to reduce cracking risk and improve machining stability.
- Hole position and assembly: It is recommended to reserve allowance for fitting/positioning holes and perform secondary processing (reaming/reaming); Please provide 2D annotations and datums for key hole positions.
- Screw connections: For repeated disassembly and assembly, it is recommended to thicken the structure and use reasonable countersunks; If more reliable connections are needed, the assembly method and number of tests can be specified in the remarks.
- Appearance surface definition: If spray painting, screen printing, or laser engraving is required, please define the display surface and non-visible surfaces to facilitate control of knife pattern direction, clamping stamping, and post-processing standards.

Polishing
Used to improve knife texture and edge feel, enhancing appearance consistency; For display surfaces, more refined transitions and texture control are recommended.
Spray paint
Used to unify color and texture (matte/matte/semi-matte/highlight, etc.), significantly enhancing the "finished product" appearance; It is recommended to provide reference images or effect requirements.
Screen printing
Suitable for logos, markings, scales, and other graphic and text information; It is recommended to provide vector files and position dimension descriptions to facilitate quick alignment and mass production consistency.
Laser carving
Used for durable labeling such as QR codes, serial numbers, and nameplate information; If you need depth and contrast, it's recommended to first confirm the style and position.
