Changzhou Jingyuan Noise Controlling Material Co.,Ltd.

Your Silence, Our Expertise

OEM Muffler R&D Capabilities:

• Acoustic Performance Engineering: Tailored noise cancellation and sound profiling to meet specific brand and market requirements.

• Backpressure & Flow Optimization: Design for maximum engine efficiency and power output.

• Material Selection & Durability Testing: Expertise in stainless steel, aluminized steel, and other alloys for superior corrosion resistance and longevity.

• Prototyping & Validation: Rapid prototyping coupled with comprehensive performance and endurance testing.

• Full Customization: Develop a muffler from concept to production, perfectly aligned with your vehicle or equipment platform.

Our production line operates on a precision-driven, customer-centric workflow that integrates advanced technology, strict quality control, and flexibility to accommodate both standard and customized orders. The process is divided into five key stages:

Stage 1: Design & Engineering

• Customization Kickoff: For tailored solutions, our acoustic engineers collaborate with the sales and R&D teams to translate customer requirements (e.g., noise reduction targets, space constraints, material preferences) into detailed 3D designs and technical drawings.
• Simulation & Validation: Using specialized acoustic simulation software, we test the design’s performance virtually—predicting noise reduction levels, airflow resistance, and structural durability—to refine the plan before production.

Stage 2: Material Sourcing & Preparation

• High-Quality Material Selection: We source premium materials such as sound-absorbing foam, mass-loaded vinyl, galvanized steel, and weather-resistant composites from certified suppliers, ensuring compliance with industry standards (e.g., ISO, ASTM) for acoustic performance and safety.
• Material Processing: Raw materials are cut, shaped, and treated (e.g., anti-corrosion coating for outdoor barriers) using automated cutting machines and laser precision tools to ensure consistency.

Stage 3: Component Manufacturing

• Production for Standard Parts: Engineers turn your needs into 3D designs. Premium materials (steel, sound-absorbing foam) are prepped via CNC cutting machines for consistent, accurate component shapes.
• Handcrafted Precision for Custom Parts: Custom sound enclosures and anechoic chamber panels require manual craftsmanship—skilled technicians assemble and seal components, ensuring airtightness (critical for noise isolation) and precise fitting.

Stage 4: Assembly & Integration

• Modular Assembly: Components are assembled in modular sections (e.g., enclosure panels, attenuator chambers) to simplify transportation and on-site installation. Each section is inspected for alignment, structural integrity, and acoustic sealing.
• Integration of Accessories: For complex solutions (e.g., anechoic chambers with testing equipment), we integrate additional features such as access doors, ventilation ports, or electrical wiring, ensuring compatibility and safety.

Stage 5: Packaging, Delivery & Installation Support

• Protective Packaging: Products are packaged in shock-resistant materials to prevent damage during transportation, with clear labeling for easy on-site identification.
• On-Site Support: For installation, our team provides technical guidance or on-site assistance to ensure proper setup, and we conduct a final performance test with the customer to confirm satisfaction.

Since our founding in 1996, we have grown from a specialized acoustic engineering firm into a global provider of innovative noise control solutions—driven by a commitment to quality, technical expertise, and a deep understanding of our clients’ evolving needs.

• 1996–2010: Founding & Early Focus: Our journey began with our founder acoustic engineer passionate about addressing unmet noise challenges in industrial and commercial settings. Initially, we focused on developing high-performance sound attenuators, a niche where we quickly gained recognition for our ability to balance noise reduction with airflow efficiency. During this period, we built our first manufacturing facility, establishing strict quality control processes to ensure every product met industry-leading standards.
• 2011–2020: Expansion of Product Portfolio: As demand for comprehensive acoustic solutions grew, we expanded our offerings to include sound enclosures and acoustic insulation barriers. This expansion allowed us to serve a broader range of industries, from manufacturing and power generation to construction and transportation. This decade marked our transition to a global service provider, with partnerships and projects spanning North America, Europe, and Asia.
• 2021–Present: Innovation & Client-Centric Growth: Today, we continue to innovate, leveraging digital tools (such as 3D modeling and acoustic simulation software) to enhance the precision and speed of our customized solutions. We have also expanded our service scope to include post-installation maintenance and acoustic monitoring, ensuring that our clients’ noise control systems remain effective long-term.

For over 25 years, our history has been defined by adaptability, technical excellence, and a relentless focus on our clients’ success. We recognized that one-size-fits-all solutions were insufficient for many clients, so we doubled down on our customized services—establishing a dedicated engineering team focused on designing tailor-made noise control strategies.

We specialize in manufacturing and supplying a comprehensive range of premium noise control products, tailored to meet diverse industrial, commercial, and specialized acoustic needs:

• Sound Attenuators: Designed to reduce airborne noise in ductwork, ventilation systems, or industrial pipelines, ensuring efficient noise reduction without compromising airflow performance.
• Commercial Airflow Attenuation Solutions: Customized for commercial spaces (such as offices, shopping malls, or healthcare facilities) to minimize noise generated by HVAC systems, fans, or air handling units—balancing acoustic comfort with optimal airflow.
• Sound Enclosures: Robust, durable enclosures engineered to isolate high-noise equipment (e.g., generators, compressors, pumps, or industrial machinery), effectively containing noise within a controlled space.
• Anechoic Chambers: Specialized, echo-free test environments used for acoustic testing, product R&D, or noise measurement—meeting strict industry standards for accuracy and performance.
• Acoustic Insulation Barriers: High-performance barriers for outdoor or indoor use (e.g., roadways, factories, or construction sites) to block and absorb noise, protecting surrounding areas from excessive sound pollution.
