Product Description
1. Material Selection
Rivet nuts are commonly made from:
Aluminum: Lightweight and corrosion-resistant, often used in aerospace and automotive applications.
Steel: Offers high strength, suitable for heavy-duty applications.
Stainless Steel: Provides excellent corrosion resistance, ideal for harsh environments.
2. Blank Preparation
Cutting: Raw material is cut into blanks of specific dimensions. This can be done using methods like shearing, sawing, or laser cutting.
Surface Treatment: The blanks may undergo surface treatments (such as cleaning or coating) to enhance corrosion resistance or prepare for further processing.
3. Forming Process
The forming process can vary based on the design of the rivet nut, but common methods include:
Cold Heading:
The blank is placed into a cold heading machine where it is shaped into the desired form by applying pressure.
This process typically creates the body and flange of the rivet nut simultaneously, resulting in high strength and minimal waste.
Thread Rolling:
After the body is formed, threads are created through a process called thread rolling, which involves deforming the material to create the desired thread profile.
This method enhances the mechanical properties of the threads due to work hardening.
4. Machining Operations
Following the forming process, additional machining may be required to achieve precise dimensions and features:
Drilling: Holes may be drilled for additional features or to create a pilot hole for installation.
Tapping: Some rivet nuts may require tapping to ensure threads are within specific tolerances.
Turning: In cases where the rivet nut needs to be shaped or finished further, a lathe can be used.
5. Surface Finishing
To enhance the rivet nut's performance and appearance, various finishing processes can be applied:
Coating: Coatings such as zinc plating or anodizing can be applied for corrosion resistance.
Polishing: This can improve surface finish and aesthetic appeal, especially for stainless steel rivet nuts.
Heat Treatment: For steel rivet nuts, heat treatment may be used to improve hardness and strength.
6. Quality Control
Quality checks are essential to ensure that rivet nuts meet the required specifications:
Dimensional Inspection: Using calipers, micrometers, or coordinate measuring machines (CMM) to check dimensions.
Thread Inspection: Ensuring threads are properly formed and meet standards using thread gauges.
Material Testing: Conducting tests such as tensile strength tests to verify material properties.
Material can be carbon steel, stainless steel, alloy, aluminum, brass, copper, bronze, steel Alloy, other type of materials.
Surface treatment: Polishing, zinc plating, hard anodizing, nickel plating, chrome plating, powder coating, phosphate coating, etc.
Our production can be made exactly according to customers' drawing. Very tight tolerance can be controlled to meet clients' requirement. All of the parts are manufactured under ISO 9001 certification and with strict quality control. 8 engineers and 8 quality inspectors with advanced equipment making sure our productions delivered with high quality and making us a professional company in this industry.
