- Product Introduction
Gray iron sand castings-they're everywhere in core components. Mechanical manufacturing, automotive, energy sectors-you name it. Performance stands out, cost stays in check. That's why they're the go-to, no fancy reasons.
Our casting know-how's been honed over years. Quality control? We don't cut corners. Whatever specs you need, we can tailor-make it. No generic solutions, just precision for your exact use case.
Core performance parameters
Material's gray cast iron, HT150 to HT300 grades. The sweet spot for most industrial needs.
Shock absorption, wear resistance, easy machining-all rolled into one. Perfect for pressure and vibration-heavy environments. The flake graphite structure acts like a built-in lubricant, extending service life far beyond ordinary materials.
Mechanical properties
Solid. Compressive strength 200-400 MPa, Brinell hardness HB170-240. Shock absorption coefficient 0.15-0.25-cuts down equipment vibration noticeably during operation.
Wear resistance index
Tested and proven. 20MPa pressure, 0.5m/s friction speed-wear stays under 0.05mm per 100 hours. That's durability you can count on.
Heat resistance
250℃ continuous work, 400℃ instantaneous high temp. Handles harsh thermal conditions without breaking a sweat.
Customized production capacity
3D simulation paired with precision casting. No more guesswork in production.
Size range's flexible. 50mm to 5000mm length, 30mm to 3000mm width, 20mm to 2000mm height.
Weight：From 1kg up to 50,000kg-small precision parts to heavy-duty components, we cover it all.
Precision standards：CT8-CT10 dimensional tolerance, surface roughness Ra12.5-Ra25μm. Tight enough for even the most demanding assemblies.
Cost control advantage
Sand molds vs. metal molds-no contest. Costs drop by 70%, new product development cycle shortens 30%. That's a massive boost to your bottom line.
Stable raw material supply chains, plus efficient in-house processes. We trim total costs by 25% without sacrificing quality. Performance doesn't have to come with a premium price tag.
Quality control system
Implement full-process quality control: Conduct spectral analysis on raw materials to detect their composition. The control accuracy of the smelting temperature of the medium-frequency electric furnace is ±10℃. The finished products need to go through 12 quality inspection procedures such as ultrasonic flaw detection and hardness testing to ensure that the defect rate of the products is less than 0.3%.
