About Us

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.

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.

Metal Mold for Exhuast Manifold, Coated sand casting

Industry exclusive: Complete exhaust manifold solutions exceeding 1 meter  in length instead of segmented

assembly.

Metal Mold for Exhaust Manifold, Sand Casting

90% of our exhaust manifolds are cost-effectively produced using molding machines, keeping both mold and casting expenses low.

Exhaust Manifold Core Box

Dandong Pengxin Machinery utilizes proprietary core box forming technology to rapidly produce casting shells and conduct pour tests post-mold completion, significantly reducing lead times.

Shell Molding Machine

To address production bottlenecks where each manifold occupies 2-3 molding machines, we implement dual solutions: our 16-machine fleet enables flexible scheduling, while partner foundries provide supplemental sand core production capacity for urgent orders, ensuring reliable delivery timelines.

Coated sand casting

Dandong Pengxin specializes in high-precision resin-coated sand casting, producing 50, 000+ annual metric tons of automotive components. Our automated lines yield CT7-8 grade castings with 3-6mm walls and Ra 12-25μm finishes. IATF 16949 certified and ISO9001.

Molding Machines

We have four iron sand mold casting machines and two FBO III automatic molding lines. Their production capability is 120 sand flasks each hour, 9000 tons each year. Their sand flask size is 605×505×200/200mm

Our Factory strength display

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 sample

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 syetem to check the pattern desgin 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
