Inquiry
  • Overview
  • Recommended Products

For commercial vehicle operators maintaining FUSO and TOYOTA trucks, drivetrain reliability directly impacts operational efficiency and total cost of ownership. Our Japanese Gray Cast Iron Flywheels are engineered to meet the exacting standards of these iconic truck manufacturers, delivering OEM-equivalent performance, exceptional durability, and perfect fitment for clutch system repairs and overhauls in demanding transportation applications.

Premium Material: High-Grade Gray Cast Iron
We utilize FC250/GC250 grade gray cast iron, specifically formulated for heavy-duty automotive applications. This material provides an optimal balance of mechanical properties crucial for truck flywheels:

  • Excellent Thermal Stability: Maintains dimensional integrity under repeated clutch engagement cycles, resisting warping and heat checking

  • Superior Vibration Damping: The flake graphite structure absorbs torsional vibrations 3-5 times more effectively than steel, protecting transmission components

  • High Compressive Strength: Withstands clutch pressure plate forces exceeding 4000 N without deformation

  • Excellent Wear Resistance: Provides consistent friction surface characteristics throughout the service life

Precision Manufacturing Process
Our production process combines advanced foundry technology with precision machining:

  • Sand Casting: Using resin-bonded molds to achieve dense, homogeneous castings with minimal internal stresses

  • CNC Machining: Precision turning of friction surfaces to ensure flatness within 0.05mm and surface finish of Ra 3.2-6.3 μm

  • Thermal Management: Controlled cooling and stress relief annealing to prevent distortion and ensure long-term stability

  • Dynamic Balancing: Computerized balancing to G6.3 grade at operational RPM, reducing vibration to below 2.8 mm/s

Performance and Application Excellence
These gray cast iron flywheels deliver critical performance characteristics:

  • Smooth clutch engagement with minimal chatter

  • Reliable starter motor gear engagement through precision-machined teeth

  • Consistent performance across temperature ranges from -40°C to 300°C

  • Service life matching OEM specifications (typically 300,000+ kilometers)

Designed as direct replacements for:

  • FUSO Canter, Fighter, and Super Great series

  • TOYOTA Dyna, Toyoace, and Coaster models

  • Various industrial engines in generator and machinery applications

Each flywheel undergoes comprehensive quality verification including:

  • Magnetic particle inspection for surface defects

  • Dimensional validation using coordinate measuring machines

  • Hardness testing to ensure 187-241 HB consistency

  • Runout measurement within 0.1mm TIR

Our technical support team provides application-specific guidance for proper installation and maintenance procedures. By maintaining strict adherence to Japanese manufacturing standards and quality control protocols, we ensure these gray cast iron flywheels deliver the reliability, performance, and longevity that FUSO and TOYOTA truck operators depend on for their daily operations, minimizing downtime and reducing total operating costs through extended service intervals and dependable performance.

Why are we called OEM experts in Exhaust Manifolds
We develop over 100 different types of exhaust manifolds every year
Dandong Pengxin  Production Process for Exhaust Manifold
Drawing Preparation: The Foundation of Precision,3D Scanning & Drafting: Our professional engineers use advanced scanners to convert samples into 2D/3D drawings (7–10 days).
Pattern & Sample Development: Where Time Invested Pays Off
Complexity: Exhaust manifolds often require 3–5 sets of metal patterns (vs. 1 set for simpler castings).Lead Time: 35–40 days for multi-cavity patterns; 25–30 days for simpler designs.
Initial Orders & Batch Production: Scaling Responsibly
Machine Allocation: One manifold order may occupy 2–3 molding machines. Our 16-machine facility prioritizes urgent orders and collaborates with partner foundries for auxiliary cores.
How Investors Can Mitigate Delays
Allocate 8–12 weeks for pattern/sample development. Compressing this risks quality failures. First batches take 20–30% longer due to process fine-tuning. Post-approval, lead times stabilize.

Why Choose Us

How did Dandong Pengxin Become a Top Manufacturer of Exhaust Manifold

To become a world-leading exhaust manifold producer, Dandong Pengxin Machinery introduced in advanced manufacturing technologies, material innovation, quality control, and supply chain efficiency. Below are the key strategies to achieve this goal.
1.Advanced Casting Technologies (1) High-Precision Casting Processes Resin-Coated Sand Casting (Main production materials are gray cast iron and ductile iron） Ensures thin-wall, complex geometries with excellent surface finish (Ra 6.3–12.5 μm). Ideal for high-performance exhaust manifolds with tight tolerances.
(2)Investment Casting(Main production materials are 316 Stainless Steel and Heat-resistant steel)
Used for premium turbine housings and racing exhaust components,especially for some freight trucks in the United States.
(3)Gravity Casting for Aluminum Manifolds
Lightweight solutions for hybrid/electric vehicle exhaust systems,Gravity casting is the preferred method for mass-producing exhaust manifolds, involving melting metals like cast iron or aluminum and pouring the molten material into preheated steel molds solely by gravitational force. The process naturally fills mold cavities without external pressure, though some advanced variants may apply minimal supplemental pressure (0.2-0.5 bar) for complex geometries. This cost-effective method yields components with uniform 3-6mm wall thicknesses and smooth surfaces, offering superior metallurgical integrity and higher production rates than sand casting, making it ideal for durable exhaust systems requiring consistent quality in high volumes.
2.Quality & Certification Standards ISO 9001/TS 16949 (IATF 16949) → Automotive quality compliance. Leak & Pressure Testing → Ensures 100% gas-tight manifolds. Thermal Cycling Tests → Simulates 10+ years of thermal fatigue. 3D Scanning & CMM Inspection → Validates dimensional accuracy (±0.1mm).
