In industries where precision, strength, and reliability are critical, you need more than just raw materials—you need engineered excellence. That's exactly what CSG Extrusion delivers. As a leading casting company, we specialize in high-quality metal casting, marine services, and advanced machining solutions, supporting clients across industrial, maritime, and manufacturing sectors.
Comprehensive Casting Services Under One Roof
At CSG Extrusion, we take pride in offering a full spectrum of casting capabilities tailored to your project's technical requirements. Whether you're building machinery components or custom marine parts, our casting services are designed for durability, performance, and cost-effectiveness.
Sand Casting
We provide reliable sand casting for complex shapes with excellent surface finishes. Ideal for low-to-medium volume production, our sand castings are used in automotive, construction, and heavy equipment industries.
Cast Iron Casting
Our cast iron casting process is perfect for parts that need high strength, rigidity, and wear resistance. Common applications include engine blocks, industrial tools, and gear housings.
Aluminum Casting
Lightweight yet robust, our aluminum casting is ideal for aerospace, marine, and high-precision mechanical parts. We use both sand and gravity die casting methods for optimal strength and surface finish.
Brass & Bronze Casting
Our brass casting and bronze casting offer corrosion resistance and aesthetic appeal, suitable for marine components, valves, and decorative hardware. For extra strength and durability in seawater environments, we also offer aluminum bronze casting, a marine-grade alloy trusted by global shipbuilders.
Lead Casting
For applications involving shielding or ballast weights, we offer accurate lead casting using refined, high-density materials. These are especially useful in marine, defense, and radiation shielding industries.
Marine Services Backed by Casting Expertise
We're not just a foundry, we're a full-service partner for marine-grade engineering. Our marine services include fabrication of corrosion-resistant parts, custom casting of propellers, pump housings, and rudder systems, all built to withstand harsh ocean conditions.
We serve shipyards, maintenance facilities, and marine equipment suppliers who demand reliability at sea.
High-Precision Machining | Lathe Machines & Custom Lathe Works
CSG Extrusion complements its casting expertise with in-house machining using industrial-grade lathe machines. Our lathe works are used to finish parts to exact tolerances, no matter how complex or delicate the geometry.
From shafts and bushings to pump parts and gear blanks, we deliver tight-turnaround lathe jobs that meet international quality standards.
Safety & Pressure Standards | Hydraulic Pressure Testing
Precision is not just about shape, it's about strength under pressure. That's why we offer hydraulic pressure testing for components that will face extreme conditions.
Whether it's a marine valve, pipe system, or industrial casting, our pressure testing protocols verify that your part can handle real-world stress, before it ever leaves our workshop.
