ABS injection mold

We specialize in custom ABS injection mold development, ABS plastic component production, and optional assembly services—not finished product trading. Our molds are engineered to maximize the performance of ABS (Acrylonitrile Butadiene Styrene) , with tailored structures optimized for ABS’s flowability, rigidity, and surface finish, delivering high-quality ABS parts for electronics, home appliances, automotive interiors, and consumer goods.

1. Custom Mold Structures: Tailored to ABS’s Molding Characteristics

ABS’s balanced properties (good flow, moderate shrinkage, high rigidity)

Our custom mold structures address these needs:

Cavity & Core: Machined via high-precision CNC machining (tolerance as tight as ±0.02mm) to leverage ABS’s excellent detail reproduction. Features include:

Smooth surface finishes (Ra ≤0.4μm) to replicate high-gloss or textured ABS parts (e.g., phone casings, appliance panels).

Reinforcement rib design (thickness 1/3–1/2 of base wall, spaced 2–3× wall height) to prevent sink marks—critical for ABS’s moderate shrinkage (1.5–2.5%).

Draft angles (1–3° for vertical surfaces) to ensure easy demolding, as ABS’s rigidity can cause sticking if angles are insufficient.

Gating System: Optimized for ABS’s flow behavior (medium melt viscosity). Options include:

Edge gates (for small-to-medium parts, e.g., electronic connectors) to minimize weld lines—ABS’s butadiene component can weaken welds if flow paths are uneven.

Hot runner systems (for large or multi-cavity parts, e.g., automotive interior trims) to maintain consistent melt temperature, reducing material waste by 15–20% and ensuring uniform part density.

Cooling System: Designed to control ABS’s cooling rate (critical for dimensional stability). Key features:

Uniform cooling channels (spaced 8–12mm apart) to avoid uneven shrinkage—prevents warping in large ABS parts (e.g., TV back panels).

Targeted cooling for thickened areas (e.g., boss structures) to reduce cycle time by 25–30%—ABS’s heat conductivity (0.19 W/m·K) requires efficient heat dissipation to avoid extended cooling.

Ejection System: Calibrated for ABS’s rigidity to prevent part damage:

Ejector pins (arranged at non-visible areas) with rounded tips to avoid marking ABS’s hard surface.

Stripper plates (for large flat parts) to distribute ejection force evenly—prevents cracking of rigid ABS components.

2. ABS Material Variants & Their Applications

ABS is available in modified grades to suit specific needs—we select the right ABS variant based on your component’s function and environment:

General-Purpose ABS (GP-ABS): Ideal for consumer goods (e.g., toy parts, household appliance housings). Offers balanced impact resistance (10–15 kJ/m²), rigidity (Shore D 75–80), and cost-effectiveness—suitable for low-to-medium stress applications.

High-Impact ABS (HI-ABS): Used for durable parts (e.g., laptop casings, tool handles). Modified with extra butadiene to boost impact resistance (20–30 kJ/m²)—withstands drops and shocks without breaking, ideal for portable devices.

Flame-Retardant ABS (FR-ABS): Perfect for electronic components (e.g., PCB enclosures, power supply housings). Meets UL94 V-0 standards—prevents flame spread in electrical applications, maintaining structural integrity at high temperatures (up to 100°C).

Glass-Filled ABS (GF-ABS, 10–30% GF): Great for structural parts (e.g., automotive interior brackets, industrial machine components). Reinforced with glass fiber to enhance tensile strength (up to 60 MPa) and reduce shrinkage (1.0–1.5%)—suitable for load-bearing ABS parts requiring dimensional precision.

High-Gloss ABS: Suitable for aesthetic parts (e.g., cosmetic packaging, audio device panels). Features a polished surface finish (no post-processing needed)—leverages ABS’s ability to retain high gloss, ideal for consumer goods where appearance is critical.

3. ABS Injection Molding Process: Optimized for Performance

Our injection process is fine-tuned to maximize ABS’s properties, with key advantages:

Precision & Consistency:

Melt temperature control (220–260°C) to ensure ABS flows evenly—avoids cold slugs or burn marks.

Injection pressure (70–100 MPa) calibrated for ABS’s viscosity—ensures full cavity filling without excessive stress (which can cause part warping).

Dimensional tolerance control (±0.03mm for small parts) via servo-driven machines—critical for ABS components requiring tight fits (e.g., electronic connectors).

Surface Quality:

Mold cavity polishing (Ra ≤0.2μm for high-gloss parts) to eliminate defects—ABS’s excellent surface reproduction ensures no visible blemishes.

Weld line reduction (via gate placement and melt temperature optimization)—improves strength and appearance of ABS parts with complex geometries.

Efficiency:

Cycle time optimization (20–40 seconds per part) via targeted cooling—balances production speed with ABS’s cooling requirements.

Multi-cavity molds (8–32 cavities for small parts, e.g., buttons) to boost output—ABS’s good flow supports uniform filling across multiple cavities, with daily production up to 50,000 parts for standard designs.

Cost-Effectiveness:

Hot runner systems reduce material waste (15–20%)—minimizes scrap from cold runners, lowering per-unit costs for high-volume ABS parts.

Integrated molding of features (e.g., ribs, bosses) eliminates post-processing—cuts labor costs and ensures consistent quality.

4. Our Services: Beyond Molds—ABS Components & Assembly

We provide end-to-end solutions for ABS production, tailored to your needs:

ABS Component Manufacturing: Produce custom ABS parts in sizes (5×5mm to 500×300mm), shapes (complex geometries, thin walls down to 0.8mm), and finishes (glossy, matte, textured). Supports color matching (RAL/Pantone codes) and post-processing (painting, plating, printing) to enhance ABS’s aesthetic appeal.

Value-Added Assembly: Optional assembly services for ABS sub-assemblies—such as attaching metal inserts (for strength), bonding ABS parts with adhesives, or integrating non-ABS components (e.g., rubber gaskets, electronic modules). Delivers ready-to-integrate sub-assemblies, saving your production time.

Custom Design Support: Offer 3D mold design and ABS prototyping (via CNC machining or injection molding). We produce 10–50 prototype parts in 3–5 days to test ABS’s performance (impact resistance, fit) and optimize the mold design before mass production.
