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 |

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 ProcessesResin-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
R&D
Our Company Owns A Provincial Level Technology Center, Plus A 15 Person R&D Team, With average 20+ Years Of R&D Experience. We can help customers design for free according to their requirements, or produce according to the drawings or samples
Production Capacity
