Yuezhong Experience Summary: How to Identify Inferior Excavator Bucket Teeth?

In the process of purchasing excavator accessories, the quality of excavator bucket teeth directly affects the working efficiency and service life of the equipment. However, the market is flooded with a large number of inferior bucket teeth, which may deceive consumers by cutting corners, false hardness ratings, etc., resulting in premature wear of equipment, reduced operating efficiency, and even safety hazards. In this article, Yuezhong, as an excavator teeth supplier, will use years of experience to deeply analyze the common traps of inferior excavator teeth, and provide practical identification methods to help you avoid purchasing unqualified products.

一、 Common traps of inferior excavator teeth

1. Cutting corners to reduce material costs

Inferior bucket teeth usually use low-quality steel or reduce the use of materials in key parts to reduce costs. Common problems include: Use of non-standard steel: High-quality bucket teeth should use high-manganese steel (such as Mn13, Mn18) or alloy steel, while inferior products may use ordinary carbon steel, which greatly reduces wear resistance and impact resistance. Reduce the thickness of key parts: Some manufacturers reduce the material thickness at the easily worn parts such as the teeth tip and teeth seat, causing the bucket teeth to wear or break quickly during heavy-load operation.

2. False hardness rating, misleading consumers

Hardness (HRC) is an important indicator to measure the wear resistance of bucket teeth. The hardness of high-quality bucket teeth is usually between HRC 45-55. However, some bad manufacturers will: falsely mark the hardness, causing the bucket teeth to wear quickly under working conditions such as sandstone and hard soil. Surface hardening treatment fraud: Some inferior bucket teeth only quench the surface, and the interior is still a soft material. Once the surface is worn, the internal structure quickly fails.

3. Inferior casting process affects structural strength

高品質 digger bucket teeth should use precision casting process, while inferior products may: have pores and sand holes: poor quality control during the casting process, resulting in internal defects and reduced impact resistance. Heat treatment process does not meet the standards: without proper heat treatment (such as quenching + tempering), the material is not tough enough and easy to break.

二、.How to identify inferior excavator bucket teeth?

1. Observe the appearance and workmanship

Check the surface finish: the surface of high-quality bucket teeth is smooth, without obvious sand holes, pores or burrs; inferior products are often rough and uneven.

Measure the thickness of key parts: Use a caliper to measure the thickness of the teeth tip, teeth seat and other parts, and compare them with industry standards. If they are too thin, they may be cut corners.

Check the casting mark: Genuine excavator bucket teeth usually have clear brand logos, material codes (such as Mn13) and production batch numbers, while inferior products may be blurred or completely missing.

2. Test hardness and wear resistance

Simple hardness test: Use a file or hardness tester to test the surface of the bucket teeth. High-quality bucket teeth should be difficult to be scratched by ordinary files.

Comparative wear test: Use new and old bucket teeth under the same working conditions for a period of time. The wear rate of inferior bucket teeth will be significantly faster than that of genuine ones.

3 . Check materials and ingredients

Spark test (for experienced technicians): Grind the bucket teeth with a grinding wheel and observe the shape and color of the sparks. High manganese steel sparks are forked, while ordinary carbon steel sparks are short and concentrated.

Spectral analysis (professional detection method): Use a metal composition analyzer to detect whether the material meets the standard (such as Mn13 should contain 11%-14% manganese).

4. Evaluate prices and supplier reputation

Be wary of too low prices: If the price of a bucket teeth is far below the market average, it is likely to be a low-quality product.

Choose a regular supplier: Give priority to authorized dealers or well-known brand direct stores to avoid purchasing from unknown channels.

When purchasing bucket teeth, you cannot make a decision based on price alone, but should consider the material, hardness, casting process and supplier reputation. Through appearance inspection, hardness test, component analysis and other methods, you can effectively identify inferior products and avoid losing more than you gain. The harm of inferior excavator bucket teeth is very serious. At the least, it will reduce the operating efficiency, and at the worst, it will cause safety hazards and threaten personal safety. Therefore, choosing regular brands and reliable suppliers can ensure the efficient, safe and long-life operation of the excavator.
