Washers Manufacturer In China

Ningbo Teng Qi Fasteners Co., Ltd is a leading washers manufacturer in China. A washer is a flat, thin, often round metal or plastic disk with a hole in the center. It is used in conjunction with nuts, bolts, screws, or other fasteners to distribute the load and prevent damage to the connected material or to the fastener itself.

Several purposes of washer:

Load Distribution:Washers provide a larger surface area for the force applied by the fastener. This helps to distribute the load more evenly, reducing the likelihood of the fastener or the material becoming damaged under pressure.
Preventing Loosening:In some cases, washers can help prevent nuts and bolts from loosening due to vibration or movement. For example, split lock washers are designed to create spring tension and resist rotation.
Reducing Friction:Washers can reduce friction between the fastener and the surface it's being tightened against, making it easier to tighten the fastener without damaging the material.
Alignment:In certain applications, washers can help align components, ensuring that they are properly positioned before being fastened together.

Type of Washer:

Flat Washers: Standard round washer with a hole in the center, used for load distribution and reducing surface damage.

Lock Washers: These include split lock washer and toothed lock washer, designed to prevent nuts and bolts from loosening due to vibrations.

Spring Washers: These washer are designed to create tension and absorb shock, often used in applications where there’s movement or vibration.

Fender Washers: These have a larger outer diameter compared to the hole, used to distribute loads over a larger area.

Wave Washers: Curved or wavy washer that create spring tension and are used to compensate for axial play or thermal expansion.

Choosing the right washer type and size is important to ensure that the fastening connection is secure, properly aligned, and protected from damage.

When selecting washer, it’s important to ensure that they are compatible with the fasteners you’re using and that they meet the requirements of your application in terms of load distribution, corrosion resistance, and other factors.

Control MethodDetail
Material Inspection:Verify the material's composition, heat treatment, and quality upon receipt. Conduct metallurgical analysis to ensure the material properties meet the standards.
Process Control:Implement strict process control measures for heat treatment, machining, threading, and any other manufacturing steps. Maintain consistent process parameters to ensure uniform quality.
Inspection Points:Introduce inspection points at various stages of manufacturing to check for defects, dimensions, and quality. Inspect threading, dimensions, surface finish, and other critical parameters.
Sampling and Testing:Regularly sample products for testing, such as tensile testing, hardness testing, and metallurgical analysis, to ensure they meet the required specifications.
Thread Inspection:Thoroughly inspect threading using proper thread gauges to ensure accurate dimensions and fit with mating components.
Traceability:Implement a traceability system to track each fasteners journey from raw material to final product. This aids in accountability and recalls if necessary.
