How does your company ensure product quality? What quality control processes are in place?

Our company is committed to delivering products of the highest quality through a comprehensive and systematic quality control process that spans the entire production cycle:

  • Incoming Quality Control (IQC):
    At the forefront of our manufacturing process, we conduct rigorous inspections on all incoming raw materials and components. This includes dimensional measurement, hardness checks, surface treatment evaluations, and material certification to ensure compliance with design and regulatory specifications. By addressing quality from the source, we eliminate potential issues at the outset.

  • In-Process Quality Control (IPQC):
    During the production process, we implement multiple critical control points to monitor and inspect semi-finished products in real-time. Through first article inspection and regular in-line inspections, we ensure the stability of production parameters, correct assembly procedures, and consistent product quality. Any anomalies are addressed immediately to maintain process integrity.

  • Final Quality Control (FQC):
    Upon completion of assembly, we conduct a thorough inspection of the finished products. This includes functional testing, appearance checks, and performance parameter verification to ensure every unit fully complies with design specifications and customer expectations before moving to the packaging stage.

  • Outgoing Quality Control (OQC):
    Prior to shipment, we perform a final sampling inspection to verify product quantity, packaging integrity, labeling accuracy, and documentation correctness. This final safeguard ensures only the best products reach our customers.

Does Forsa hold any relevant quality certifications?

Yes, we are certified under the following international quality management systems and continuously integrate advanced quality control methodologies to enhance our manufacturing capabilities:

  • ISO 9001: Quality Management System
  • IATF 1649: Automotive Quality Management System

These certifications not only signify the standardization of our manufacturing and management processes but also confirm our technical and quality capabilities to align with the international automotive industry.

What performance and durability tests are conducted on shock absorbers?

To ensure that our shock absorbers deliver superior performance and high reliability across various application environments, Forsa conducts a series of critical performance and durability tests, including:

  • Damping Force Test (Dyno Test):
    Measures compression and rebound damping curves at various speeds to ensure consistency and precision in damping characteristics.

  • Durability Test:
    Simulates long-term use with hundreds of thousands to millions of cycles to verify structural integrity and seal durability.

  • Salt Spray Test:
    Exposes the product to high-salinity, high-humidity conditions to evaluate corrosion resistance—ensuring reliable performance in coastal or humid environments.

  • Temperature Cycling Test:
    Simulates extreme climate conditions to test performance stability in both high-heat and sub-zero environments.

  • Fatigue Test:
    Conducts high-cycle, high-load fatigue testing on critical structural components to ensure that materials and design can withstand long-term repetitive stress without failure.

  • NVH Test (Noise, Vibration, Harshness Test):
    Evaluates the shock absorber's noise and vibration performance during operation to ensure smooth and quiet running, enhancing ride quality.

All test data is thoroughly recorded, and a quality history is established for customer project tracking and technical report requirements.

Do you provide warranty for OEM/ODM products? What are the warranty terms?

Yes, we provide comprehensive warranty coverage for all OEM/ODM products to protect your investment and ensure long-term satisfaction:

  • Warranty Coverage:
    Our warranty covers manufacturing defects and material issues related to the product itself. Each product is labeled with a production batch number, which serves as the reference for warranty validation.

  • Warranty Period:
    All products are covered by a 2-year (24-month) warranty from the date of shipment.

  • Claim Process:
    In the event of a claim within the warranty period, we follow our internal Quality Incident Handling Procedure to promptly investigate and address the issue. The product will undergo professional inspection to determine the root cause and responsibility.

  • Cost Responsibility:
    If the issue is determined to be unrelated to our manufacturing process—such as improper installation, abnormal use, unauthorized modifications, external damage, or use beyond design specifications—the customer will be responsible for any related costs, including but not limited to shipping, inspection, and handling fees. This policy ensures a fair and transparent approach for all parties.

We firmly believe that strict quality control and comprehensive testing are the foundation of delivering exceptional products. Should you have any further questions regarding our quality management system or wish to explore specific details, please feel free to contact us at any time.
