High Abrasion-Resistant Alloy Steel Cast Excavator Bucket Teeth & Adapters for Mining

Product Introduction

Product Overview

Bucket teeth are important excavator components, much like human teeth, and are also vulnerable parts. A tooth seat and a tooth tip joined by a pin shaft make up the assembly. Since bucket teeth wear out and fail, only the tooth tips have to be replaced.
Sand casting, forging and precision casting are the ways bucket teeth are made. Compared with precision casting and forging, sand casting costs the least but gives lower craftsmanship and tooth quality. Forging: higher cost, with better craftsmanship and tooth quality. Precision casting: moderate cost, but raw material requirements are very strict and the craftsmanship level is relatively high. Because of their ingredients, some precision cast bucket teeth have even surpassed forged bucket teeth in wear resistance and quality. Precision casting is the mainstream process for making bucket teeth on the market.
Bucket teeth are consumable spare parts of excavating machinery, and they break up minerals, rocks and other materials. They should last longer, so they need high hardness with a low wear rate and breakage rate. For that reason they are made from high manganese alloy steel or high chromium alloy steel, cast on an advanced automatic casting line and given a special heat treatment, which improves product quality and useful life!

Key Advantages

Fairly consistent quality
Cast wear parts made of high manganese-chromium alloy steel have a longer record of service life than those made of other kinds of material.
NGZR has over 10 years of experience in R&D, manufacturing and after-sales service for high Mn & high Cr cast wear parts, such as high chrome cast grinding media, high Mn-Cr alloy cast mill liners and crusher wear parts, for the mining and aggregate industries.

Reduced operating cost
Cast wear parts of Mn-Cr alloy steel (bucket teeth, adapters and guard boards) combine a long service life with consistent quality.
NGZR combines a large production capacity with an advanced lost foam process, a fully automatic precision casting line and a manual resin-sand wooden mould casting production line. This lets us offer all customers more competitively priced products, so their purchase cost falls below its previous level.

Tailored alloy steel composition
To suit customer needs, the NGZR foundry can adjust the chemical composition of the alloy steel (Mn /Cr) or add other special metallic elements (Si /Mo /Cu /Ni, etc). Together with special heat treatment, this gives these cast excavator bucket wear parts particular mechanical properties that fit each customer's different working conditions.

Custom drawings, sizes and shapes
The NGZR foundry can customize excavator bucket wear parts according to the drawing dimensions of the customer's existing ones. We can also modify the shape, thickness and wear resistance of the existing parts, helping customers reduce wear parts cost and raise production efficiency.

On-site measurement & installation guidance
Should a customer be unable to supply drawings of the excavator bucket wear parts currently in use, NGZR will send a service engineer free of charge to measure and draw up the product dimensions.
On request, NGZR can offer a door-to-door installation guidance service, which is paid.
