About SUPER SDLG Loader GET Parts

Our customers once conducted comparative tests between the bucket teeth we produced for SDLG and those from other suppliers. The test results showed that our bucket teeth had a 30% longer service life than theirs.

How did this gap come about?

Based on the samples provided by the customer, our comprehensive analysis concludes that: they did not design the bucket teeth specifically for the customer’s operating environment, compatible machinery, or performance requirements. The chemical composition used is extremely limited, achieving only the minimum necessary for casting without considering usability or durability. Their bucket teeth exhibit uneven hardness distribution—different stress zones possess inconsistent hardness levels, and surface hardness differs from core hardness. Even areas requiring enhanced hardness receive no corresponding reinforcement. Outdated casting techniques result in coarse internal microstructure, accelerating wear and causing frequent chipping.

So, how did we approach this?

First, we upgraded the raw materials from standard carbon steel to custom alloy steel, precisely adding composite microalloying elements such as chromium, molybdenum, nickel, and boron. This enhances the bucket teeth’s hardness and low-temperature impact toughness, preventing fractures in low-temperature environments or hard rock conditions. We also implemented precise raw material screening, significantly reducing internal impurities and minimizing microscopic microcracks. This approach eliminates potential risks of bucket teeth fractures.

We have implemented improvements and adjustments to our production processes, adopting “precision die forging” and “vacuum lost foam casting” techniques. These methods eliminate internal porosity and sand voids in steel components, resulting in denser internal structures, superior surface finish, and a direct increase in service life of 30% to 50%.

We have elevated our single heat treatment process into a proprietary composite heat treatment technique. By employing differentiated heat treatment methods that integrate quenching, carbon distribution, and bainitic isothermal transformation, we not only perform surface heat treatment for surface strengthening but also achieve a significant enhancement in internal hardness. This process further improves the hardness and toughness of the cutting edge, resulting in superior rock penetration capability.

Of course, structural adjustments are essential. To enhance the wear resistance of bucket teeth and extend their service life, they must possess excellent self-sharpening properties. Through specialized structural design, we ensure that bucket teeth maintain a sharp profile throughout wear, thereby reducing machine resistance and fuel consumption.

We welcome you to contact us and experience our high-wear-resistant bucket teeth.
