Product Overview

 

 

Tweeter Mounting Brackets: Injection-molded and die-cast pods engineered to decouple high-frequency drivers from vehicle door panels and dashboards, eliminating mechanical buzz, rattle, and squeak issues.
Microphone Plastic Housings: Multi-component shells featuring tight acoustic chamber tolerances, electromagnetic interference shielding compatibility, and ergonomic split-line designs for handheld, boundary, and studio condenser microphones.

 

Types and Configurations
 

Tweeter Mounting Brackets

Surface-Angle Adjustable Pods: Dual-axis swivel housings utilizing ribbed ball-and-socket joints for customized directional staging on vehicle A-pillars and dash decks.
Flush-Mount Retention Rings: Low-profile bezels featuring integrated cantilever snap-fits and stainless steel spring clips for rapid, toolless snap-in installation.
Acoustic-Decoupled Hybrid Brackets: Rigid structural substrates overmolded with Thermoplastic Elastomer lips to isolate driver vibration from surrounding sheet metal.

Microphone Plastic Housings

Handheld Shells: Two-piece symmetric barrels incorporating internal PCB mounting ribs, anti-roll geometry, and secure thread-locking interfaces.
Desktop and Boundary Bases: Weighted enclosures featuring low-center-of-gravity mass distribution, integrated cable strain relief channels, and acoustic port baffling.
Miniature Capsule Enclosures: Ultra-thin-wall (under 0.8 mm) molded caps designed for lavalier and headset applications without compromising structural rigidity.

 

 
Materials and Construction
 
01/

PC/ABS: Selected for automotive interior components requiring high impact resistance, dimensional stability, and UV resistance under direct sunlight.

02/

PBT-GF30 (30 Percent Glass-Filled): Utilized for high-stress tweeter brackets requiring high flexural modulus and creep resistance under sustained fastener torque.

03/

POM (Acetal): Applied to snap-fit functional elements requiring high fatigue endurance across repeated assembly cycles.

04/

Damping and Overmolding: Shore A 50 to 70 TPE compounds chemically bonded to rigid substrates to absorb high-frequency acoustic resonance.

05/

Surface Texturing: Mold-tech and VDI standards applied directly to steel cavities for scratch-resistant matte finishes or high-gloss acoustic chambers.

06/

Threaded Fastening Solutions: Brass and 303 stainless steel inserts (M2 to M5) installed post-molding via high-frequency thermal insertion, guaranteeing uniform pull-out and torsional resistance.

 

 

Key Features

Dimensional Repeatability: Linear shrink rates controlled within plus or minus 0.003 mm per mm via scientific molding parameter optimization, preventing warp in thin-wall housing ribs.


Acoustic Chamber Integrity: Minimized parting-line flash (under 0.02 mm) in internal acoustic paths to prevent air turbulence and frequency distortion.


Fatigue-Resistant Snap-Fits: Cantilever designs simulated and tested for cyclic deflection, enduring over 500 assembly and disassembly cycles without structural whitening or fracture.


Thermal and Environmental Endurance: Polymer formulations verified via accelerated weathering and thermal shock testing, maintaining structural integrity from minus 40 degrees Celsius to plus 85 degrees Celsius.

FAQ

 

 

Q: What is your standard timeline from CAD data receipt to T1 samples?

A: Following a 48-hour DFM review and client sign-off on mold flow analysis, tool fabrication takes 3 to 5 weeks depending on multi-slide complexity. T1 samples, alongside initial inspection reports, are delivered within 7 business days post-molding trial.

Q: How do you eliminate sink marks on thick-walled sections of tweeter brackets?

A: Sink marks are prevented during the engineering phase by executing CAE mold-flow simulations. We apply strategic core-out techniques, optimize gate placement (such as utilizing sub-gates or tunnel gates near thick bosses), and design conformal cooling channels to ensure uniform volumetric cooling shrinkage.

Q: What is the typical Minimum Order Quantity for custom-molded parts?

A: MOQ is driven by polymer resin batch sizes and press setup optimization, typically starting at 2,000 units per production run. Pilot production runs or Engineering Verification Test quantities can be negotiated with adjusted piece pricing.

Q: How do you ensure the pull-out strength of threaded brass inserts in plastic microphone housings?

A: We utilize thermal press-in or ultrasonic insertion methods rather than conventional molded-in insertion. This technique melts a precise micro-layer of plastic around the knurled insert, achieving pull-out and torsional torque values that exceed standard molded-in insert benchmarks.

Q: What documentation is provided for automotive-tier tweeter bracket shipments?

A: Every production lot is accompanied by a Certificate of Conformance, raw material Certificates of Analysis, material compliance submissions, and a full PPAP Level 3 documentation package upon initial submission.

Q: How is intellectual property and tooling security handled for custom housing designs?

A: All client CAD data, technical drawings, and tool designs are protected under strict, mutual Non-Disclosure Agreements. Production molds are engraved with client ownership plates, housed in dedicated secure tool rooms, and strictly operated solely for authorized purchase orders.
