I don't have complete drawings, can I send inquiry?
Yes, we can help you analyze based on your description, samples and photos.
I am not sure if you can do my parts?
Most of our customers come to us because “others say they can’t do it”.
Are you a factory or a trader?
We are a factory and have a project management team that can handle the technology, cost and delivery at the same time.

Our Expertise in Carbon Steel Casting Parts
We specialize in engineering-grade carbon steel casting components designed for load-bearing, impact-resistant, and cost-efficient industrial applications. Our manufacturing capability covers thin-wall sections, complex internal runners, and heavy-duty geometries required for harsh mechanical environments.
Using precision investment casting, sand casting, and controlled pouring & solidification simulation, we produce custom carbon steel assemblies for automotive, construction hardware, mining equipment, lifting devices, agricultural machinery, and energy-sector components.
Our size capability ranges from 0.1 to 24 inches, with part weights from 1 ounce to 50 pounds, supporting both prototype and stable mass-production batches. Every casting undergoes mechanical-property verification to ensure required strength, toughness, fatigue resistance, and dimensional consistency based on final operating conditions.
Our Manufacturing Approach
To ensure consistent casting quality, we've broken down “control” into tangible data and processes: material batch traceability, comprehensive casting parameter logging, pre-production simulation validation, and digital verification for every batch inspection—replacing reliance on master craftsmen's intuition.
Alloy Composition and Melting Control
We apply spectral analysis and in-furnace composition adjustments for carbon and alloy steels, such as AISI 1020, 1045, 4130, 4140, and 8620, as well as ASTM A216 WCB. Focus points include C, Mn, Si, S, P, Cr, Mo, Ni precision control to achieve target strength, hardenability, and weldability, while preventing porosity, segregation, and grain coarsening.
Engineering Design of Mold & Feeding Systems
Mold engineering is optimized using flow and solidification simulation to control shrinkage, hot spots, crack-risk zones, and inclusion trapping.
Heat Treatment for Mechanical Performance
Heat-treatment processes vary based on grade and performance requirements, including:
Precision Machining & Quality Inspection
CNC finishing achieves dimensional accuracy of ±0.05–0.1 mm with CMM verification for complex tolerances. The surface finish typically reaches a Ra of 3.2–6.3 μm, depending on the casting and machining stages. Complete inspection options are available, including UT, MT, tensile, hardness, metallography, run-out, thread gauge validation, and alignment with engineering drawings and acceptance standards.

What are the Advantages of Carbon Steel Casting Parts ?
Suppose you're unsure whether carbon steel is the right material. In that case, we help evaluate stress-load conditions, cost trade-offs, heat-treatment feasibility, and fatigue life through early-stage manufacturability assessments and process simulations.
