Skip to content Custom ABS components for equipment housings, covers, brackets, and prototype assemblies. TENGHUI provides in-house CNC milling and turning for prototypes, low-volume orders, and repeat production, with coordinated finishing and inspection.
Send your CAD files, drawings, and quantity requirements for a quotation and manufacturability review.
ABS—acrylonitrile butadiene styrene—is a thermoplastic commonly selected for its balance of impact resistance, stiffness, machinability, and appearance. Properties vary by grade, stock form, processing history, and test conditions. Material availability and any specified performance requirements are reviewed during quotation.
| Material Characteristic | General Guidance | What to Specify |
|---|---|---|
| Density | Common unfilled grades are approximately 1.04–1.06 g/cm³ | Confirm the specific grade where component weight is critical |
| Impact Resistance | Suitable grades provide useful toughness for housings and handled components | Operating temperature, impact conditions, and relevant test requirements |
| Strength & Stiffness | Suitable for many covers, enclosures, and lightly loaded parts | Loads, wall thickness, support points, and allowable deflection |
| Heat Performance | Depends on grade, load, exposure time, and component design | Actual operating temperature and duration |
| Dimensional Stability | Residual stress, machining heat, clamping, and geometry can affect dimensions | Critical fits, flatness, inspection conditions, and assembly requirements |
| Chemical Resistance | Compatibility varies with the chemical, concentration, stress, and exposure | Cleaning agents, oils, adhesives, and other contact substances |
| Color & Appearance | Stock colors and appearance depend on availability | Required color, cosmetic surfaces, and whether painting is acceptable |
| Special Requirements | Flame resistance, electrical properties, and regulated uses require specific grades and documentation | Applicable material specifications and acceptance criteria |
*Heat deflection temperature is a test result under defined conditions, not a universal continuous-use temperature. Use the selected grade’s data sheet for engineering assessment.
Choose a finish based on appearance, handling, assembly, and dimensional requirements. TENGHUI coordinates surface preparation and finishing according to the approved project requirements.
Parts retain visible tool marks without an additional decorative finish. This is a practical option for internal components, fit checks, and functional prototypes.
Painting provides options for color, gloss, and texture on visible housings, covers, and presentation models. Provide the required RAL or Pantone reference.
Controlled sanding can reduce visible machining marks and prepare accessible surfaces for painting. The result depends on geometry and starting surface.
A matte or textured appearance can be reviewed using suitable preparation and coating methods. The achievable result depends on part design and specification.
Silk screening or pad printing can be evaluated for logos, labels, and identification marks on suitable surfaces. Provide artwork, dimensions, and color references.
ABS can be a practical choice for prototypes and equipment components where its material properties meet the application requirements.
CNC machining is a practical option when you need parts made from ABS stock without mold tooling. It suits many prototypes, assembly checks, and low-volume components.
For complex prototype geometry, SLA printing with an ABS-like resin may be considered. ABS-like resin is a different material and should not be assumed to match ABS in impact behavior, heat resistance, or chemical compatibility.
If injection molding is required, tooling, material, quantity, and project feasibility are reviewed separately. There is no fixed quantity at which one process is always the most economical.
Tolerances are confirmed after reviewing part size, geometry, stock condition, and finishing requirements.
Thin walls, long features, large flat areas, and temperature changes can make tight tolerances more difficult to maintain. Mark critical dimensions, fits, and inspection requirements on your drawing so achievable limits can be agreed before production.
General tolerances should follow the drawing or the requirements confirmed for the order.
We plan workholding, material removal, and machining sequence around the part geometry.
For parts sensitive to residual stress or deformation, staged machining and time between operations may be considered. Final inspection focuses on the specified dimensions and assembly features.
Thin walls, uneven sections, and unnecessary tight tolerances should be reviewed during the manufacturability assessment.
Painting and printed markings can be evaluated for suitable parts.
Provide your color reference, artwork, cosmetic surfaces, and acceptance requirements. For close color matching or repeat cosmetic orders, an approved physical sample is recommended.
Paint and ink thickness, adhesion, and compatibility should be considered where surfaces are handled, cleaned, or assembled.
Standard ABS is generally better suited to indoor applications than prolonged outdoor exposure.
For outdoor parts, the material grade, UV exposure, temperature, moisture, and coating system require review. A black material or protective paint should not automatically be assumed to provide adequate weather resistance.
Share the expected environment so suitable material options can be assessed.
ABS may be considered for non-patient-contact housings, covers, and equipment components where its properties meet the design requirements.
Cleaning agents, operating temperature, flame resistance, and any applicable material requirements should be specified. Material availability and documentation must be confirmed before ordering.
No medical, food-contact, or biocompatibility status is implied by the material name alone.
Straightforward CNC prototypes can often be completed in approximately 3–7 working days.
Larger quantities, complex geometries, staged machining, painting, and special inspection may require additional time. We confirm the delivery plan after reviewing your files and project requirements.
Please provide:
For functional parts, include relevant loads, operating temperatures, and exposure to cleaning agents or chemicals.
Upload your 2D drawings (PDF/DWG/DXF) and 3D CAD files (STEP/IGES). We evaluate part geometry, materials, and tolerances within 24 hours.
Once we receive your design files, our senior manufacturing engineers will manually perform a comprehensive DFM review and deliver an accurate, optimized quote within 24 hours.
