Our multi-ring integrated plastic mounts are engineered as high-rigidity, precision-injected structural components—ideal for centralized positioning and modular integration of multiple parts in medical, electronic, and industrial applications. With a robust black engineering plastic construction, these mounts combine spatial organization, dimensional accuracy, and easy assembly to streamline complex component layouts.

I. Product Overview: Integrated Ring Structure for Centralized Management

Designed to organize and secure multiple components in a single assembly, these mounts feature a functional, rigid design:
  • Material:

    • ABS/PA66: High structural strength (tensile strength ≥ 70 MPa), impact resistance, and dimensional stability—suitable for load-bearing integration scenarios.

  • Core Structural Features:

    • 1 Large Central Ring + 3 Peripheral Small Rings: Optimized for housing different-sized components (e.g., tubes, sensors, modules), with reinforced ribs connecting rings to prevent deformation under 300N radial load.

    • Positioning Protrusions: Built-in alignment tabs inside/around each ring ensure ±0.1mm precision when mating with target components.

    • Universal Compatibility: Customizable ring diameters (central: 20–50mm; peripheral: 10–25mm) to fit specific part dimensions.


II. Injection Mold Engineering: Precision for Multi-Ring Alignment

The mount’s performance relies on mold design tailored to its integrated ring geometry:

1. Mold Design Highlights

  • Ring Dimensional Control: 5-axis CNC-machined cavities (tolerance ±0.05mm) ensure consistent inner/outer diameters across all rings—critical for component fit.

  • Rib & Undercut Handling: Slider mechanisms form reinforced ribs and positioning tabs without damaging delicate ring edges during ejection.

  • Uniform Cooling: Conformal cooling channels follow the ring/rib contour, reducing cycle time by 20% and eliminating warpage in the integrated structure.

2. Injection Process Parameters (PA66)

Parameter Specification Purpose
Melt Temperature 260–280°C Ensures smooth flow into rib/ring intersections (no voids).
Mold Temperature 80–100°C Maintains dimensional stability of interconnected rings.
Injection Pressure 1000–1200 bar Fills thin rib sections (1.5–2mm width) for structural integrity.
Cooling Time 45–55s Fully cures the integrated structure to avoid post-mold deformation.

III. Key Advantages

  • Centralized Integration: Organizes 4 components in one mount, reducing assembly time by 40% vs. individual positioning.

  • High Rigidity: Reinforced rib design resists bending/twisting, even in high-vibration environments (tested to 5G vibration for 24h).

  • Precision Alignment: ±0.1mm ring positioning tolerance ensures consistent component fit across production batches.

  • Cost-Effective: Single-piece injection replaces multiple discrete brackets, cutting material and assembly costs by 30%.


IV. Application Scenarios

These mounts excel in scenarios requiring organized, precise component integration:
  • Medical Devices: Centralized holder for infusion tubes, sensor modules, or diagnostic equipment components.

  • Electronics: Positioning frame for multi-interface connectors, small motors, or circuit board modules.

  • Industrial Instruments: Mounting base for pressure sensors, fluid line ports, or actuator components.


V. Customization & Quality Assurance

  • Customization Options:

    • Adjust ring sizes, quantities, or positioning tabs to match your specific components.

    • Material upgrades (e.g., flame-retardant ABS for electronics, chemical-resistant PA66 for medical use).

  • Quality Control:

    • CMM-verified dimensional accuracy for all rings and positioning features.

    • Impact resistance testing (passes 1.5m drop test without cracking).

    • RoHS-compliant (free of heavy metals) for electronics/medical applications.
