Plastic pad mold

We specialize in custom plastic pad mold development, plastic pad component production, and optional assembly services—not finished product trading. Our molds are engineered to match your plastic pads’ unique needs (e.g., ultra-thin thickness, insulation performance, sealing edges) , with tailored structures, material compatibility, and optimized injection molding to deliver high-performance plastic pad parts for electronics, furniture, and industrial equipment.

1. Custom Mold Structures: Tailored to Plastic Pad Requirements

Plastic pads (e.g., electronics insulation pads, furniture buffer pads, equipment sealing pads) demand extreme flatness, precise thickness control, and functional adaptability—our mold structures are customized to address these key demands:

Cavity & Core: Machined via high-precision CNC grinding (tolerance as tight as ±0.01mm for thickness, ±0.02mm for size) to ensure uniform pad thickness (0.1–3mm, based on use) and clean edges. For pads with holes (e.g., for fixation or wire passage), the mold’s core pins are calibrated to ±0.005mm to avoid hole misalignment. Surface polishing (Ra ≤0.2μm) ensures the pad has no burrs—critical for insulation or sealing functions.

Gating System: Designed for thin pad filling without damaging surface integrity. Micro edge gates (width 0.8–1.2mm, positioned at non-functional edges) or tab gates (small extended tabs for easy trimming) are used—they leave minimal residues and avoid affecting the pad’s flatness. For ultra-thin pads (≤0.3mm), hot runner systems with micro nozzles ensure stable plastic flow, reducing material waste by 12–18%.

Cooling System: Optimized for thin, flat pad designs. Parallel cooling plates (spaced 5–8mm apart) cover the entire mold cavity, ensuring even heat dissipation—preventing warping (a major issue for thin pads) and reducing cooling time by 25–35%. For pads with localized thickened areas (e.g., sealing edges), additional cooling pins are added to maintain uniform temperature.

Ejection System: Uses ultra-thin ejector pins (diameter 0.8–1.5mm, arranged in a matrix) or stripper plates to avoid pad deformation. Ejector force is precisely controlled to ensure the pad is released flat—no bending or creasing that would compromise its insulation or sealing performance.

2. Suitable Plastic Materials: Matched to Plastic Pad Applications

Plastic pads serve diverse functional roles (insulation, buffer, sealing, wear resistance)—we select materials based on performance needs, environmental adaptability, and use scenarios:

PET (Polyethylene Terephthalate): Ideal for electronics insulation pads (e.g., PCB board isolation pads, battery buffer pads). Offers excellent electrical insulation (dielectric strength ≥15kV/mm), high temperature resistance (up to 120°C), and good mechanical strength—prevents short circuits and withstands electronic device operating temperatures.

PE (Polyethylene): Used for lightweight buffer pads (e.g., furniture leg pads, packaging protection pads). Provides good impact resistance, low friction coefficient (avoids surface scratches), and chemical resistance (to water, oils)—suitable for low-load, non-high-temperature indoor scenarios.

Silicone-Modified PP: Perfect for sealing pads (e.g., equipment junction pads, kitchen appliance waterproof pads). Combines PP’s rigidity with silicone’s elasticity—offers good sealing performance (prevents water/dust ingress) and temperature resistance (up to 100°C), compatible with humid environments.

PTFE (Polytetrafluoroethylene): Great for high-performance industrial pads (e.g., machinery sliding pads, high-temperature equipment insulation pads). Features extreme temperature resistance (-200°C to 260°C), chemical inertness (resistant to most acids/alkalis), and low friction coefficient—suitable for harsh industrial conditions.

TPU (Thermoplastic Polyurethane): Suitable for flexible buffer pads (e.g., electronic device anti-drop pads, sports equipment cushion pads). Offers high elasticity (Shore A 60–80) for shock absorption, wear resistance, and transparency—ideal for applications requiring both protection and aesthetics.

3. Injection Molding Process: Optimized for Plastic Pad Quality

Our injection molding process is fine-tuned to solve common thin pad issues (filling difficulty, warping, surface defects) with these core advantages:

Thickness Consistency: Low-pressure (50–80MPa) and precise temperature control (180–240°C, material-dependent) ensure plastic fills the cavity evenly—each pad’s thickness variation is kept within ±0.01mm, meeting strict insulation or sealing requirements.

Surface Integrity: Mold cavity polishing (Ra ≤0.2μm) and controlled injection speed (30–50mm/s) eliminate surface defects like sink marks or bubbles. Post-molding inspection via optical scanners checks for flatness and burrs, with a defect rate below 0.2%.

Efficient Mass Production: Multi-cavity molds (32–64 cavities, based on pad size) maximize output. For standard 20×20mm pads (0.5mm thick), daily production reaches 100,000–150,000 components. Automated trimming and sorting systems reduce labor costs and ensure consistent quality.

Cost Optimization: Hot runner systems minimize material waste; for high-volume orders (200,000+ pads), per-unit cost can be reduced by 10–15%. Two-shot molding is optional for pads needing dual properties (e.g., rigid core + flexible edge), integrating functions in one step.

4. Our Services: Beyond Molds—Plastic Pads & Assembly

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

Plastic Pad Manufacturing: Produce custom pads in various sizes (5×5mm to 200×200mm), thicknesses (0.1–3mm), and designs (solid, perforated, with adhesive layers). Supports custom colors (RAL/Pantone codes) or surface treatments (anti-static coating, flame-retardant finishing).

Value-Added Assembly: Optional assembly services for pad sub-assemblies—such as attaching double-sided adhesive tapes (for easy installation), laminating with metal foils (for enhanced conductivity), or cutting pads into complex shapes (for equipment fitting). Delivers ready-to-integrate sub-assemblies, saving your production time.

Custom Design Support: Offer 3D mold design and rapid prototyping (via SLA 3D printing). We can produce 30–50 prototype pads in 2–3 days for you to test insulation performance, buffer effect, or sealing tightness—optimizing the mold design before mass production.
