Technical Advantage:

Teeth & adapters & cutting edges are key components of the excavator bucket assembly.  These components are subject to extreme forces, wear and impact during excavation.  Therefore, strict technical quality control must be maintained to ensure that these parts meet the required standards of durability, strength and performance.Ensuring technical quality control of these G.E.T components is critical to the smooth operation and longevity of the excavators & bulldozers & loaders & scrapers & motor graders...

Firstly, the components must come from a reputable manufacturer or supplier who has a good reputation of supplying high-quality products. Before making a purchase, it is important to conduct thorough research and seek advice from industry experts to ensure the supplier has a solid reputation for producing reliable and durable excavator parts. The whole process is controlled strictly from Pattern Design-Wax Model Manufacturing-Wax Model Assembly-Model Shell Making-Dewaxing-Model Shell Baking-Melting-Compound Analyse-Pouring-Sand Stripping-Heat Treatment-Shot Blast Cleaning-Inspection-Machining-Packing-Warehouse, with using many profession inspection machines like Spectrum analysis instrument & impact test machine & Universal strength tester & X ray machine & Microstructure machine & Hardness tester & Hinged arm CMM &CMM & Height indicator & Roughness tester & MPI & UT & Checking fixture .

Once components are obtained, strict quality control processes must be implemented at all stages of production and post-production. This includes meticulous inspection of raw materials, precision machining processes, heat treatment procedures and surface coating applications.  In addition, it is critical to conduct comprehensive dimensional inspections, material hardness testing, and metallurgical analysis to verify component integrity and performance.

In addition, regular quality audits and performance testing should be conducted to evaluate the wear resistance, impact strength and overall functionality of bucket teeth, adapters, cutting edges, protectors, lip shround and heel shround.  This will help identify any deviations from specified standards and enable timely corrective measures to be taken.

We attach great importance to the quality, and quality control is the core of our company . We have a complete strict QC team from raw material to finished products with using professional mechanical equipment and a perfect quality inspection process .

As a main manufacturer of G.E.T spare parts ,we offer a wide range of spare parts of bucket teeth & adapters, blades,protectors, side cutters,heel shround,lip shround, pins & retainers, bolts & nuts to match, such as brand Caterpillar (including J series, K serious, A series,Lip Shround, Side Cutter, Heel Shround,Protector...),Volvo,ESCO(Super V series),Komatsu(Kmax tooth,Side Cutter,Ripper Tooth..),Doosan,Hyundai,Bofors,MTG,JCB,Uniz Series,Liebherr,John Deere, Combi etc.

Direct replacement parts for leading brands can be provided and used for excavators,loaders,bulldozers,graders,scarifies,both in the construction and mining sectors.

From design-mould-sample-mass production process control, every step of production will be carefully checked to ensure good performance and appearance . Different products use different materials such as Z1/Z11 & Z2/Z12 &Z3/Z13/A9,Z4/Z14/Z10 and heat treatment processes to ensure the best cost value ,With the use of high-quality raw materials, our products have high abrasive resistance, performance, and durability .

All the finished products will be fully inspected again before delivery, so most of the major customers are zero complaints .Our products quality control is very stable, but free replacements can be provided if there are any quality problems .

Development Advantage:

Bucket teeth & adapters play an important role in the construction and mining industry, and their development has changed dramatically over time . Form humble origins in ancient civilizations to today’s modern innovations, the evolution of bucket teeth has played a vital role in increasing the efficiency and durability of heavy machinery .

Fast forward to today, the development of bucket teeth has reached a new pinnacle of innovation. With the advent of modern engineering and materials science, manufacturers are now able to produce bucket teeth specifically designed for optimal performance and longevity. Advanced alloy, heat treatment and investment casting technologies allow the teeth to withstand the harshest working conditions and provide superior digging power . Advanced manufacturing techniques such as computer-aided design and 3D modeling can create highly specialized bucket teeth to meet the specific needs of different industries .

The development of bucket teeth not only improves the performance of heavy machinery, but also has a positive impact on safety and environmental sustainability. By increasing digging efficiency and reducing the need for frequent replacements, modern bucket teeth help provide a more sustainable and cost-effective approach to construction and mining operations. Additionally, the durability of advanced bucket teeth ensures a safer working environment, minimizing the risk of equipment failure and potential accidents on the working site .

According to the constantly updated market demand,we continuously develop new products as per OEM samples to meet customers’ needs .If there are special appearance or material requirements, we can customize as per customers’ drawings or samples .

Our technical team ever worked for NINGBO TONGDA CASTING, who have first-class technical ability . Among them, the technical supervisor has more than 20 years of experience in the development and production of teeth and structure parts ,ever served many leading companies as BYG,PENGO,JCB,FEURST,JOC ....
