Trumpet Airbox Injection Mold

Core Competencies

• Acoustic structure mold manufacturing technology: For intake mesh grilles and flow guide chambers, mold steel utilizes high-polish performance grades, processed through precision EDM and grinding to ensure specific surface roughness standards, with airflow noise below design thresholds during operation.
• Complex structure molding capability: Intakes often feature clips, sealing grooves, and multidirectional ribs. The mold employs multislide and internal core pulling mechanisms to ensure smooth undercut ejection and accurate assembly dimensions for subsequent horn unit and frame mounting.
• Rich surface treatment processes: Supports various mold surface treatments, including grain etching, matte sandblasting, and localized gloss finishes, producing intake components with clear texture and fluid lines that align with motorcycle design trends.
• Onestop component delivery: Beyond mold manufacturing, capabilities extend to plastic welding and assembly, completing intaketoseal welding and waterproof assembly to reduce client supply chain management costs.

Technical Specifications

• Acoustic permeability: Utilizes low airflow resistance engineering plastic formulations, with molded components exhibiting sound pressure loss below design values within specific frequency ranges, ensuring horn sound quality without attenuation.
• Dimensional stability: Scientifically arranged cooling channels effectively control injection molding shrinkage rates, ensuring dimensional consistency across high-volume production and preventing warpage deformation that compromises sealing performance.
• Surface consistency: Specially treated mold cavities produce components free of flash and sink marks, ensuring uniform color after painting or plating.
• Ejection reliability: Mold draft angles and rib thickness are precisely calculated, combined with ejector pin and air ejection systems to ensure mesh structures eject without scratching or deformation.

Application Scenarios

• Street motorcycles: Applicable to horn air intakes, speaker housings, and flow guide components for naked bikes, sport bikes, and cruisers.
• Off-road motorcycles: Mold manufacturing for waterproof air intakes on enduro and motocross models, meeting high-intensity vibration environments.
• Scooters: Front or side-mounted horn air intakes for urban commuter models, supporting grained surfaces and complex contour designs.
• Electric motorcycles: Warning horn intake systems for new energy twowheelers, meeting lightweight design and waterproof rating requirements.
• Motorcycle aftermarket: Custom intake mold development and production services for modification brands.

FAQ & Solutions

Q1: Short shots or incomplete filling in motorcycle intake mesh grilles after molding, how to resolve?
Solution: This typically results from inadequate mold venting or excessive flow resistance from thin ribs. We incorporate venting grooves and porous steel inserts during mold design, optimizing wall thickness transitions at grille intersections; simultaneously guiding clients to increase melt temperature and injection pressure to ensure complete filling in thin-wall areas.
Q2: Air leakage or abnormal noise after the intake horn assembly, what causes this?
Solution: This often relates to sealing surface flatness deviation or clip dimensional inaccuracy. We utilize precision grinding during cavity machining to ensure sealing surface flatness within 0.05mm, with adjustable insert structures for clip positions to facilitate postcorrection, and conduct full inspection of mating surfaces after molding to ensure assembly airtightness compliance.
Q3: For molds exported to Europe, how to ensure service life and maintenance convenience?
Solution: Leveraging 15 years of export experience, our mold designs fully comply with DME and HASCO standards. Hot runner systems utilize internationally branded components, accompanied by detailed maintenance manuals and spare parts lists. Critical wear parts such as slides and ejector pins adopt standardized designs for local procurement and replacement, ensuring long-term stable mold operation.
