Explore our custom-engineered high-performance components, developed for automotive, agricultural, and industrial automation networks globally.
Established in 2013, HC Machine has emerged as a premier Chinese innovator in high-precision casting and forging technology.
We operate at the intersection of metallurgy and advanced mechanical engineering. By combining modern investment casting practices with computer-controlled machining, we offer single-source manufacturing capabilities for critical industrial sectors. Our engineering experts support customer projects from chemical profiling and tooling layout through to heat treatment and finish machining.
HC Machine holds ISO 9001 certification and operates a rigorous three-tiered inspection system. We are committed to achieving zero defects and high delivery compliance, making us a strategic manufacturing partner for OEMs worldwide.
Discover Our Plant CapabilitiesOur state-of-the-art facilities integrate design simulation, precision casting, and advanced dimensional metrology to produce parts that perform under pressure.
We maintain an in-house engineering team where over 30% of the workforce consists of technical staff. Ten dedicated quality inspectors implement exhaustive tracking to ensure a >99.5% product qualification rate.
Our CNC machining facility features 40 modern machining centers, precision CNC lathes, and advanced Coordinate Measuring Machines (CMM). This layout allows us to comfortably process annual production volumes exceeding RMB 30M.
We maintain structured quality gates at every step of production. Our incoming material testing, in-process dimension checks, and final testing ensure that our components comply with your exact engineering requirements.
The modern industrial manufacturing landscape requires global procurement teams to look beyond low prices. Leading industrial operations prioritize supply chain resilience, carbon compliance (such as CBAM), material transparency, and strict geometric consistency.
At HC Machine, we specialize in high-integrity casting processes designed to solve these exact challenges. Our capabilities range from custom-alloyed steel compositions that withstand high temperatures to ultra-durable carbon steels designed for mechanical stress.
Our precision castings are engineered to perform in demanding, high-load operational environments:
Direct from our manufacturing lines, featuring our high-performance oil valves, tractor parts, and custom silica sol components.
Cast with high-grade low-temperature carbon steel (LCC), designed for leak-free service in industrial fluid control lines.

Delivering high surface finish quality and dimensions that require minimal secondary machining operations.
View DetailsOur engineering approach is designed to prevent casting defects before production begins.
One of the primary challenges in steel casting is shrinkage porosity, which occurs when molten metal contracts as it cools. At HC Machine, our engineers utilize advanced thermal simulation software to model the casting process.
This software allows us to optimize riser placement and dimensions, ensuring that molten steel feeds continuously into the cooling zones. This virtual prototyping step minimizes the risk of internal micro-shrinkage and subsurface gas pockets.
By adjusting sand mold venting and metal pouring temperatures, we maintain complete control over the grain structure, producing parts with high mechanical strength and impact toughness.
We offer both high-precision silica sol investment casting and cost-effective water glass casting to balance precision with project budgets:
| Parameter | Silica Sol Investment Casting | Water Glass Casting |
|---|---|---|
| Surface Roughness | Ra 3.2 - 6.3 μm | Ra 12.5 - 25 μm |
| Dimensional Tolerance | ISO 8062 CT4 - CT6 | ISO 8062 CT7 - CT9 |
| Minimum Wall Thickness | 1.5 mm | 3.0 mm |
| Best Suited For | Complex, thin-walled automotive & valve components | Heavy-duty agricultural machinery brackets & links |

Our second curated selection of specialized alloy components, agricultural hardware, and high-tolerance industrial castings.
How our internal control standards help keep global operations running smoothly.
We verify critical tolerances using coordinate measuring machines (CMM) and air gages. This setup allows us to confirm that machined dimensions match your drawings before the parts leave our plant.
We perform optical emission spectroscopy (OES) testing on every batch of molten steel. This analysis helps us verify that the concentrations of carbon, manganese, chromium, and other alloy elements meet your target standards.
Managing risk through material compliance, certifications, and responsive engineering support.
We supply EN 10204 3.1 material test certificates with every shipment. These reports confirm the chemical composition, tensile strength, yield point, elongation, and Charpy impact values of your castings.
Located near Ningbo Port, we offer easy access to major shipping routes. We support multiple shipping terms (FOB, CIF, DDP) and can integrate with your local distribution centers to help manage inventory levels.
Our engineers work directly with your design teams via online conferences. We review casting features, suggest cost-effective design changes, and resolve tolerances before cutting tool steel molds.
