For the rotary engine enthusiast seeking to unlock maximum performance, the flywheel is not just a component; it's a critical tuning element. Our High-End Lightweight 12A Flywheel, engineered to a meticulously balanced 10-pound weight, represents the pinnacle of drivetrain optimization for Mazda's iconic rotary engine. This premium flywheel is designed to deliver dramatic improvements in engine response, acceleration, and overall driving exhilaration.

Advanced Material for Optimal Performance

Crafted from a billet of high-strength chromoly steel or a premium aerospace-grade aluminum alloy, this flywheel achieves an ideal balance of minimal weight and uncompromised durability. The use of chromoly steel ensures immense tensile strength to handle the high-RPM stresses of the 12A engine without risk of failure. The significant weight reduction over the stock unit drastically reduces the engine's rotational mass, which is key to its performance benefits.

Precision Engineering and Manufacturing

The manufacturing process begins with a solid billet, CNC-machined to exacting tolerances. This method, superior to casting, ensures a perfectly uniform

Custom Auto Assembly High-Performance Flywheel for RENAULT FW116 Sizes 50kg and 100kg details

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).

Process designs derive from engineering drawings

Leveraging customer-provided 3D designs, our engineers develop precision mold models and perform comprehensive casting simulation analysis prior to production.

3D scanners

Many distributor clients lack 2D drawings - Dandong Pengxin's engineering team expertly converts physical samples into precise manufacturing drawings through professional scanning and reverse-engineering processes.
