Explosion-proof Die Castings

We developed our explosion-proof die castings at the request of an Australian client who needed something special. They worked in mining areas, where heavy trucks often ran over manhole covers and drains. Normal cast iron parts would break into pieces, which could fall in and block the pipes. They needed something unbreakable - so we made these products.

We use Zamak3 zinc alloy and die casting. Zinc alloy is tough, not brittle like cast iron. We also made the walls thicker and added grid-shaped reinforcing ribs on the back. The result? Even if a pickup truck drives over it, the part bends but does not shatter. In our factory, we tested samples by striking them with a hammer. They flattened but stayed in one piece - no fragments came off. These products keep your drains clear and safe.

We make these products with large machines, using 500-ton die casting presses. Higher pressure ensures the material fills the mold tightly, producing a very dense part. High density also makes the product resistant to water and rust. We tested the parts by soaking them in salt water for one month. The surface showed only minor white rust, which wiped off easily. This makes them suitable for use near the ocean or in salty soil. With 20 years of mold experience, we know how to achieve the right density, ensuring these products last in harsh environments.
