Reunion's in-house injection molding capability allows outdoor equipment manufacturers to tailor the M15 plastic waterproof connector to their specific design requirements—from color and texture to cable assemblies and packaging.
Housing Color– Any RAL or Pantone color molded directly into the material—no painting or secondary finishing required. Color is integral and will not chip or peel.
Surface Texture– Smooth, matte, or textured finishes for grip or aesthetic requirements.
Cable Assemblies– Custom length (0.1m to 20m), PUR (oil/chemical-resistant) or PVC jacket, single-ended or double-ended, with or without overmolded strain relief.
Contact Loading– 2, 3, 4, or 5 pins as required; unused positions left empty or fitted with dummy pins for mechanical balance.
Cable Marking– Custom printing or heat-shrink labels for circuit identification.
Connector Orientation– Straight or right-angle versions for panel-mount or cable-mount applications.
Packaging– Anti-static bags, reels, or custom-labeled cartons for automated assembly lines.
Reunion operates a dedicated injection molding facility within its 4,000m² Shenzhen plant:
Material Drying– PA66 is precisely dried to remove moisture and prevent molding defects.
Injection Molding– Precision molding on automated presses with ±0.02mm tolerance control; color pigment added directly to resin.
Contact Stamping & Plating– High-speed stamping from copper alloy with selective gold plating in automated barrel-plating lines.
Secondary Operations– Insertion of gold-plated contacts and O-ring seals into the molded housing.
Cable Processing– Automated cutting, stripping, and tinning; in-house PUR/PVC cable extrusion for custom cable assemblies.
Assembly– Semi-automated lines with vision-inspected contact placement and torque-controlled fastening.
Electrical Testing– 100% verification of continuity, insulation resistance (≥5000MΩ), and dielectric withstand.
Environmental Sampling– Batch sampling for IP67 immersion (1m, 30min),and thermal cycling .
Packaging– Anti-static vacuum sealing with desiccant; export-grade carton packing with custom labeling as required.
| Certification | Scope |
| ISO 9001:2015 | Quality management—design, production, and after-sales service. |
| ISO 14001:2015 | Environmental management—verified waste reduction and sustainable practices. |
| ISO 13485:2016 | Medical device quality management—applicable for M15 used in diagnostic or monitoring equipment. |
| UL Recognized | Component-level safety certification for North American markets. |
| RoHS | Restriction of hazardous substances—compliance with EU Directive. |
Reunion's M15 plastic connector production line operates under strict process controls.. IP67 sealing is verified on every production batch through actual immersion testing (1m, 30 minutes) using water. Test records, material certificates, and inspection reports are retained for each batch, supporting your quality audits and customer documentation requirements.
The M15's PA66 housing is inherently corrosion-proof—it does not rust or oxidize. In independent salt spray testing per ASTM B117 (96 hours), we observed no surface degradation, no reduction in sealing integrity (IP67 verified post-test), and contact surfaces remained within specification due to gold plating. By contrast, brass connectors with nickel plating often show visible corrosion (pitting, white rust) within 48-72 hours of salt spray exposure, which can compromise the O-ring seal and thread integrity. For marine environments (offshore platforms, coastal lighting, ships), the plastic M15 significantly outperforms plated metal connectors.
Yes. While the housing is plastic, the threaded locking interface incorporates metal inserts to ensure consistent torque retention over hundreds of mating cycles. Reunion's testing shows retention force remains >90% of initial specification after 500 mating cycles, thread wear is minimal due to metal-to-metal thread engagement, and the O-ring seal remains effective across the temperature range. For high-cycle applications (e.g., annual maintenance requiring connector disconnection), we recommend lubricating the O-ring with silicone grease at each mating to extend seal life.
