Gmetal Thread Rolling Service

Gmetal provides Thread Rolling Service for metal fasterning and stamping parts which you orderd.

Gmetal Thread Rolling Machines

Gmetal mainly fabricates brackets like Antenna Mounting Brackets, Solar Mounting Brackets and Ubolts which has thread. In order to produce high quality brackets, Gmetal has many advanced thread rolling machines as the following passage shows:

  • Flat Die Thread Rolling Machines: The workpiece is squeezed between the two dies, and the thread is formed as the dies rotate and apply pressure to the workpiece. Flat die thread rolling machines are commonly used for producing straight threads, such as machine screws and bolts.
  • Cylindrical Die Thread Rolling Machines: Cylindrical die thread rolling machines use cylindrical dies with thread profiles on their periphery. The workpiece is rolled between the cylindrical dies, and the threads are formed by the pressure and rotation of the dies. These machines are suitable for producing straight threads and can handle larger workpieces.
  • Planetary (Ring) Die Thread Rolling Machines: Planetary thread rolling machines use ring-shaped dies with thread profiles on the inside. The workpiece is positioned inside the ring die, and multiple planetary dies are used to apply pressure to the workpiece from different angles. This results in faster thread rolling and is ideal for high-volume production of screws, bolts, and threaded rods.
The Process of Thread Rolling

The Process of Thread Rolling

The following steps are the main process that Gmetal used in thread rolling service:

  1. Workpiece preparation: The first step is to prepare the workpiece for the thread rolling process. This step involves cleaning the surface of the workpiece to remove dirt, oil or debris that may affect the quality of the threads. The workpiece should also be inspected for any defects.
  2. Setting up the thread rolling machine: The thread rolling machine needs to be set up with the proper dies or rollers to match the desired thread form, pitch and diameter.
  3. Feeding the workpiece: Load the prepared workpiece into the thread rolling machine. And depending on the machine type and design, the workpiece can be automatically fed or manually positioned for the rolling process.
  4. Thread Rolling Process: Depending on the metal parts you need, Gmetal will select optional thread types to manufacture high quality products.
  5. Finishing pass (optional): Depending on the application and specific requirements, a finishing pass can be performed to obtain a smoother surface finish and improve thread accuracy.
  6. Inspection and Quality Control: After the thread rolling process is complete, the threads are inspected to ensure they meet the required specifications. This step includes checking pitch, diameter, thread form and surface finish.
  7. Additional processes (if necessary): In some cases, thread rolled workpieces may undergo additional processes, such as heat treatment or coating, to further enhance their application-specific properties.

The Benefits of Thread Rolling

Gmetal Thread Rolling Service has many benefits, the key advantages are as following:

  • Improved Thread Strength: Rolled threads have increased strength and fatigue resistance compared to cut threads. The cold-forming process of thread rolling enhances the grain structure of the material, making the threads less prone to failure under load.
  • Enhanced Surface Finish: Thread rolling produces smoother and more precise threads with a better surface finish. This smoothness reduces friction and wear, making threaded connections easier to assemble and disassemble.
  • Consistency and Accuracy: Thread rolling machines use precisely designed dies or rollers, ensuring uniform thread dimensions and pitch. This results in threads with high accuracy and consistency across multiple workpieces.
  • No Need for Secondary Operations: Rolled threads often require no additional finishing processes since they already have a smooth surface finish. This eliminates the need for additional steps such as deburring or polishing, further streamlining production.
  • Cold Forming Process: Thread rolling is a cold forming process, meaning it is performed at room temperature. This avoids the introduction of heat-affected zones or residual stresses that could weaken the material.
  • Thread Versatility: Thread rolling can produce a wide range of thread profiles, including straight threads, tapered threads, and multiple-start threads, offering flexibility in design and application.
