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 steelUsed 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 StandardsISO 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

Production Capacity
At Pengxin-Casting, process control begins as early as in the planning and development phase of the products. We support our customers to perform all required tests and inspections in a laboratory. It goes without saying that our plants are certified according to ISO 9001 and IATF16949 in line with a validated quality management. As we strive to accomplish our zero-error policy, you can rely on the following process control measures: Drawing Control → Pattern Control → Raw Material Control → Molding Sand Control → Pouring Process Control → Raw Casting & Machining Control →Other Requirement Control→ Packing & Delivery Control
Pattern Control
We simulate feeding system to check the pattern design from the filling process and material solidification. In this way, we can shorten the mold development cycle, reduce the number of mold trials and improve product quality. The software we use includes
Abaqus, Moldflow and Moldex 3D, simulate feeding system, reduce casting defects and improve efficiency
Raw Material Control
We check the chemistry property as new raw material coming
Machining Control
All dimensions 100% measuring
Raw material spectral analysis and X-ray detection Critical dimensions with CMM measuring
