Mold for plastic dialers

We specialize in custom plastic dialer mold development, plastic dialer component production, and optional assembly services—not finished dialer trading. Our molds are engineered to fit your unique dialer designs (e.g., rotary structures, number/scale markings, anti-slip features) , with tailored structures, material compatibility, and efficient injection molding to deliver high-performance plastic dialer parts.

1. Custom Mold Structures: Tailored to Dialer-Specific Needs

Every plastic dialer mold is customized based on your dialer’s function (e.g., rotary operation, push-dial, digital marking) , size, and assembly requirements. Core structural components include:

Cavity & Core: Machined via high-precision CNC machining (tolerance as tight as ±0.015mm) to replicate dialer details—such as rotary grooves (for smooth rotation), embossed/engraved numbers/scales (0.1–0.3mm depth for clear visibility), anti-slip textures (on dialer edges), and shaft holes (for rotating axes, diameter tolerance ±0.008mm to ensure seamless rotation).

Gating System: Customized to avoid visible marks on dialer surfaces (critical for user interaction) and reduce material waste. Latent gates (hidden at the dialer’s shaft hole or edge) are preferred—they leave no obvious traces and eliminate post-molding trimming. For small dialers (≤50mm diameter), pin gates are used for precise material flow.

Cooling System: Designed for dialers’ typical "disc/ring" shapes—spiral or circular cooling channels ensure even heat distribution. This prevents warping (a common issue for thin dialer edges, 0.8–2mm thickness) and reduces cycle time by 18–25%, supporting mass production.

Ejection System: Uses ejector sleeves (for shaft holes) or stripper rings (for circular dialers) to protect precision parts. Ejector sleeves avoid damage to the shaft hole’s inner surface, ensuring smooth rotation of the final dialer component.

2. Suitable Plastic Materials: Matched to Dialer Applications

We select plastic materials based on your dialer’s use scenario (e.g., consumer electronics, industrial control, medical devices) to balance durability, usability, and cost. Recommended materials include:

ABS (Acrylonitrile Butadiene Styrene): Ideal for standard consumer dialers (e.g., retro landline phones, kitchen timers, small household appliances). Offers good rigidity (Shore D 75–80), easy surface printing/engraving (for numbers/scales), and moderate impact resistance—suitable for daily, low-to-medium wear use.

PC (Polycarbonate): Perfect for high-demand dialers (e.g., industrial control panels, medical equipment, automotive dash dialers). Features excellent heat resistance (up to 130°C), shatterproof properties, and chemical resistance (to cleaning agents)—ensures durability in harsh environments (e.g., high temperature, frequent disinfection).

TPR/TPU (Thermoplastic Rubber/Urethane): Used for dialers needing anti-slip or soft-touch features (e.g., fitness equipment dialers, elderly-friendly devices). Provides elastic feel (Shore A 50–70), good grip, and wear resistance—reduces hand slippage during operation. Can be used for two-shot molding (combining with ABS/PC for rigid core + soft surface).

PA6 + Glass Fiber (10–20% GF): Suitable for heavy-duty dialers (e.g., outdoor equipment, construction machinery, marine control dialers). Combines high tensile strength (reinforced by glass fiber) and weather resistance—withstands humidity, temperature fluctuations (-30°C to 110°C), and repeated mechanical stress (e.g., frequent rotation).

POM (Polyoxymethylene): Great for precision rotary dialers (e.g., measuring instruments, laboratory equipment). Boasts low friction coefficient (0.15–0.3), high dimensional stability, and smooth surface finish—ensures quiet, smooth rotation (no "sticking" or "jitter") over long service life (≥50,000 rotations).

3. Injection Molding Process: Optimized for Dialer Quality & Efficiency

Our injection molding process is fine-tuned for plastic dialer production, addressing its unique requirements (e.g., rotary precision, surface marking clarity). Core advantages include:

Rotary Precision Control: Computer-controlled servo molding machines (pressure accuracy ±0.5 bar) ensure uniform plastic filling in dialer cavities—critical for consistent shaft hole size and groove depth. This guarantees smooth rotation (rotational resistance variation ≤5%) across all batches.

Surface Marking Clarity: Molding parameters (temperature 230–280°C, based on material) are optimized to replicate embossed/engraved numbers/scales with sharp edges. Post-molding defects (e.g., blurred markings, sink marks on dialer surfaces) are controlled via real-time monitoring—defect rate kept below 0.4%.

Flexible Process Adaptation: Supports two-shot molding for dialers needing soft-touch surfaces (e.g., TPU over ABS) and insert molding (for metal shafts, if required). Enables integration of multiple features in one step, reducing assembly steps later.

Cost-Effective Mass Production: Multi-cavity molds (4–16 cavities, based on dialer size) enable fast cycle times (25–45 seconds per batch). For standard 60mm-diameter dialers, daily production capacity reaches 20,000–35,000 components—lowering per-unit costs for large orders (10,000+ parts).

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

We provide end-to-end solutions for plastic dialer production, not just molds:

Plastic Dialer Component Manufacturing: Produce custom dialer parts (e.g., rotary discs, dialer covers, shaft sleeves) using our tailored molds. Components can be made to match your size (30–150mm diameter), color (custom RAL/Pantone codes), and functional requirements (e.g., waterproof, anti-fingerprint).

Value-Added Assembly: Optional assembly services for dialer sub-assemblies—such as inserting metal rotating shafts, attaching anti-slip pads, bonding dialer discs to brackets, or installing position sensors (for digital dialers). Delivers ready-to-integrate sub-assemblies, saving your production time and labor.

Custom Design Support: Offer 3D mold design and rapid prototyping (via SLA 3D printing). We can produce 5–15 prototype dialers in 3–4 days for you to test rotation smoothness, marking visibility, and assembly fit—optimizing the mold design before mass production.

We are plastic mold maker and can provide custom mold service, we can make injection molds, blow molds, rotational molds and die-casting molds.
