Cast iron robot castings | EPC, a new era of "iron arm"

In the wave of intelligent manufacturing, robots are no longer sci-fi imagination, but "steel employees" in factories, logistics, welding and assembly lines.

What supports the efficient, stable and lasting operation of these intelligent "iron arms" is their inherent high-precision cast iron structural parts-we inject solid and reliable "bones" and "joints" into intelligent equipment by EPC process.

Why do high-end robots choose our EPC iron castings?

Complex structure, integrated molding-bid farewell to tailor-made welding and enhance rigidity

Robot base, arm, reducer shell, joint bracket and other parts are often complicated in structure, uneven in wall thickness and staggered in internal cavities.

Traditional sand molds can't meet the precision requirements, while EPC adopts foamable EPS model, which can realize near-net forming, no flash and no draft inclination without parting surface, greatly reducing the subsequent machining amount and improving the rigidity and dynamic stability of the whole structure.

Reliable material and excellent performance-HT 250/Qt 500 is optional, with both strength and toughness.

We select high-strength gray cast iron (HT250/HT300) or nodular cast iron (QT500-7, QT600-3), giving consideration to shock absorption, wear resistance and fatigue resistance, especially suitable for high-load working conditions under high-speed reciprocating motion of robots.

The internal structure of the casting is compact and the metallographic structure is uniform, which ensures long-term operation without deformation and stability.

Accurate size and consistent repetition-tolerance control reaches CT7 level.

Relying on digital modeling, high-density foam molding and vacuum negative pressure pouring system, we realize the dimensional control accuracy within ±0.3mm, and the batch consistency is high, which perfectly matches the strict requirements of the robot for assembly accuracy and motion repeatability.

Green and intelligent manufacturing, environmental protection and high efficiency-no binder, less pollution and high yield.

The EPC process does not need traditional clay sand or resin sand, and does not produce waste sand pollution; After the foam model is gasified, more than 95% of it is converted into gas to be exhausted.

With the help of environmental protection treatment system, clean casting and low-carbon production can be truly realized, which is in line with the sustainable development concept of smart factories.

No matter six-axis, four-axis or special customized models, we can provide one-stop casting solutions from design optimization, simulation analysis to batch delivery.

Casting is more than "shaping";

Intellectual creation begins with "casting the foundation"

Behind every efficient robot, there is a silent but key iron casting-it doesn't speak, but carries thousands of cycles;

It does not shine, but supports the intelligent body.

We use the "invisibility" of the lost foam to create the "tangible" of the robot;

With the "constancy" of ingenuity, the "infinity" of intellectual creation is achieved.
