speed vs quality: How to select the right production tooling for the job

Selecting the right production tools is crucial to achieving the right balance between ensuring that products are made efficiently without compromising on quality. 

The saying horses for courses has never been more appropriate when selecting production tools and understanding the differences and advantages of each type of tool, manufacturers can make informed decisions that enhance their assembly processes, ensuring both efficiency and quality.

The two most commonly used types of production tools are clutch tools and transducerised tools. While both serve the purpose of applying torque to fastenings in the assembly process, they operate on different principles and offer distinct advantages. Let’s delve into the key differences between these two types of tools.

clutch Production Tools

Clutch tools are equipped with a mechanical clutch mechanism that disengages the drive once the preset torque is reached. This ensures that the fastener is quickly tightened to the desired torque, however accuracy can be lost during the fastening so they are best suited to non-safety or quality critical joints.

Clutch tools are commonly used in applications where high volume and moderate precision are required. This can be across various industries, including automotive, aerospace, electronics, and consumer goods. In the automotive industry, for example, they are used to assemble non safety or quality critical joints such as door joints or seat assemblies.

Some key features of Clutch tools are:

  • Simplicity: Due to their simple design, they are easy to install, operate and maintain.
  • Cost-Effective: Mechanical clutch tools are usually more cost effective compared to more advanced tooling.
  • Torque Control: The torque is set manually on the tool by adjusting a dial with the provided tool. This provides a straightforward method of controlling torque but does then require manual checking with a torque analyser on a regular basis.
  • Efficiency: Clutch tools can be a speedy way to achieve torque assemblies in high-volume production environments.
  • Ergonomics: Many clutch tools are designed with ergonomics in mind, reducing the physical strain on operators. This is especially important in repetitive assembly tasks.
However Clutch tools do have some limitations:
 
  • Accuracy: Most clutch tools, regardless of the brand only achieve an accuracy of +/-10% to target torque
  • Quality Control: Most clutch tools cannot detect if the target torque was achieved in a defective way, such as with a cross threaded screw.
  • Traceability: Many clutch tools operate in a stand-alone manner and do not connect to a controller or network which means there is no way to record tightening data

clutch vs Transducerised Production Tools

Transducerised Production Tools

Unlike clutch tools, transducerised tools are equipped with a transducer that measures the actual torque applied to the fastener in real-time. This data is fed back to a connected controller, allowing for precise torque control and monitoring.
They are widely used in industries that require high precision and traceability, such as automotive, aerospace, and medical device manufacturing.

Here are their key features:

  • Precision and Accuracy: Transducerised tools offer superior torque accuracy compared to clutch tools. The real-time feedback loop ensures that the exact torque is applied, reducing the risk of over-tightening or under-tightening.
  • Data Recording: These tools can be integrated with data systems to provide detailed records of each fastening operation. This capability is crucial for quality control and traceability in complex assembly processes.
  • Programmable: The target torque is set digitally either on the tool or via the controller or a remote software on a computer. This allow for multiple programmes on one tool and ease of switching between them meaning you can use one tool across multiple joints with different torque requirements.
  • Advanced Features: Transducerised tools come with advanced features such as torque & angle measurement, batch counting, sequencing and early error detection.

However there are some factors to consider:

  • Speed: The high accuracy and smart features can mean the tools are slower to achieve target torque which can have an affect on output.
  • Cost: Transducerised tools are generally more expensive than non-transducerized tools due to their advanced technology and precision components
  • Complexity: While transducerised tools offer many advantages, they are generally more expensive and complex to set up, operate and maintain compared to clutch tools.
  • Calibration: To maintain the highest level of accuracy tools must be calibrated after a set amount of cycles or annually, whichever comes first. This needs to be considered as part of the total cost of ownership.

Conclusion

Selecting the right production tooling is a crucial step in the manufacturing process. By carefully considering factors such as production volume, design complexity, material requirements, precision, cost, and lead time, you can find the optimal balance between speed and quality. This ensures that your products are manufactured efficiently and to the highest standards.

Making the choice between clutch tools and transducerised tools depends on the specific requirements of your manufacturing process. Clutch tools are ideal for applications where simplicity, cost-effectiveness, and moderate precision are sufficient. In contrast, transducerised tools are the go-to choice for high-precision applications that demand detailed data integration and advanced torque control.

By understanding the differences and advantages of each type of tool, manufacturers can make informed decisions that enhance their assembly processes, ensuring both efficiency and quality.
