polish
It is used to improve the feel of knife grain and edge, and improve the consistency of appearance; it is recommended for finer transition and texture control on the display surface.
ABS Engineering Plastic
ABS is a commonly used engineering plastic, with advantages such as "good processability, good appearance, and low cost," suitable for appearance prototypes and light-load structural parts.
Quote checklist: Upload your 3D model and, when available, a 2D drawing. Identify the required process, material, quantity, critical dimensions, finish, appearance standard, and target delivery date.
Key Material and Manufacturing Parameters
Engineering note: Values below are typical reference ranges. Final manufacturability, tolerances, material condition, surface finish, cost, and lead time depend on the drawing, geometry, quantity, and selected process.
Upload CAD files and mark critical features for an engineering review before production.
| Process | CNC machining (engineering plastics) |
|---|---|
| Material | ABS (acrylonitrile-butadiene-styrene copolymer) |
| Typical color | Natural color/black, etc. (Subject to spot plates/bars; painting is recommended for high appearance consistency requirements) |
| Dimensional tolerance | Conventional ±0.20 mm (subject to structure and datum); it is recommended to mark tolerances or note "accuracy first" for key holes/critical surfaces |
| Minimum wall thickness | Recommended ≥1.0 mm (thin-walls/large flat surfaces are recommended to be reinforced or increased in thickness to reduce the risk of deformation) |
| Minimum aperture | Recommended ≥1.5–2.0 mm; it is recommended to reserve a margin for mating holes/assembly holes and re-expand/ream holes |
| Chamfer/fillet | It is recommended that the inner angle be made R0.5 or above (to reduce the risk of stress concentration and cracking) |
| Strength and rigidity | General engineering plastic level, suitable for light-medium load structural parts; if high impact/high wear resistance, PC/PA/POM, etc. can be evaluated |
| Service temperature | Suitable for normal to medium temperature environments; it is recommended to evaluate more temperature-resistant material systems in scenarios close to heat sources/long-term high temperatures. |
| Electrical characteristics | Has certain electrical insulation properties (suitable for structural insulation parts in non-high voltage harsh environments) |
| Surface and Appearance | Machined surfaces can achieve a better appearance; it is recommended to polish + spray paint to unify texture and color difference for display parts. |
| Typical applications | Structural parts, cosmetic parts, fixtures and fixtures, assembly verification parts, small batch end-use parts |
| Finishing | Polishing, screen printing, laser engraving, painting |
| Typical lead time | Relevant to size, quantity, processing difficulty and finishing; clear delivery and expedited options will be given after uploading the file |
Finishing
spray paint
Used to unify color and texture (matte/semi-matte/high-gloss, etc.) to significantly improve the "finished product" look and feel; it is recommended to provide reference pictures or effect requirements.
screen printing
Suitable for logos, scales and other graphic information; it is recommended to provide vector files and position and size instructions to facilitate quick alignment and mass production consistency.
Laser engraving
Used for durable markings such as QR codes, serial numbers, and nameplate information; if there are requirements for depth and contrast, it is recommended to confirm the style and position first.
Why Choose Engineering Plastics-ABS (CNC Machining)
Strong versatility and high cost performance
It is more balanced between cost, processing efficiency and performance, and is suitable for rapid iteration and small batch delivery.
Large appearance and finishing space
Combined with polishing and painting, a more unified display effect can be obtained; it can also be combined with screen printing/laser engraving to achieve clear identification.
Suitable for structural parts and functional validation
Used for assembly verification, interference inspection, fixtures and light-medium load parts, with high delivery efficiency.
Electrical insulation application friendly
Suitable for structural insulation and shell parts in non-harsh environments; if there are any standard requirements, please state them in the remarks.
Recommended Applications
- General structural parts/cosmetic parts: Requires controllable costs, fast processing, and stable delivery
- Functional validation sample: Assembly verification, interference inspection, structural first version trial fitting
- Finishing required: Polished/painted for uniform texture; screen printing/laser engraving for logo
- Insulating structural parts: Shell/bracket type parts that have certain requirements for electrical insulation
Consider Another Material or Process
- Prolonged high temperature close to heat source: It is recommended to evaluate more temperature-resistant materials
- High impact/high toughness: It is recommended to evaluate PC, PA and other more impact-resistant materials
- High wear resistance/low friction sliding: It is recommended to evaluate material systems such as POM, PA+ addition, etc.
- Highly chemically corrosive environment: It is recommended to choose more chemical-resistant materials according to medium and temperature.
Design and DFM Guidelines
- Wall thickness and deformation control: Avoid ultra-thin large flat surfaces; reinforce or increase thickness if necessary to reduce processing stress and risk of deformation during use.
- Internal corner fillets and stress concentration: Internal corners should be rounded as much as possible (recommended R0.5+) to reduce the risk of cracking and improve processing stability.
- Hole location and assembly: It is recommended to reserve allowance for mating holes/positioning holes and perform secondary processing (enlarging/reaming); please provide 2D markings and benchmarks for key hole locations.
- Screw connection: For repeated disassembly and assembly scenarios, it is recommended to thicken the structure and provide proper countersinking; if a more reliable connection is needed, assembly method and frequency can be noted in the remarks.
- Appearance surface definition: If painting/screen printing/laser engraving is required, please define the display surface and the invisible surface to facilitate control of the direction of the knife pattern, clamping printing and finishing standards.
