THE BRIEF

The client enlisted Twenty20 Engineering to design and create the fabrication pack for a furnace test rig. They aimed to conduct prolonged tests on samples of their heat shield and insulation products for a sustained period at 1200 degrees.

The client also included the following points in their specification:

• The test rig needed to be mobile, enabling it to be relocated within the factory facility for use in different departments.
• The heating element inside the rig must be separated from any metallic components using appropriate insulation.
• The heating element required a 90-degree rotation to ease the installation and removal of samples.
• Although the test piece needed to be fully enclosed, it was crucial to incorporate features that would facilitate continuous airflow for efficient heat dissipation.

CHALLENGE

This project faced several challenges, which Twenty20 Engineering tackled by specifying that all components are in contact with the heating element made of a machinable ceramic material. Ensuring that metallic components are isolated from direct contact with high-temperature to facilitate the required 90-degree rotation of the heating element, the control box features a cleverly designed hinge and secure locking feet. Furthermore, 15mm laser-cut holes were strategically placed on the enclosure to maintain airflow for optimal performance while preventing finger access during operation.

The rig was mounted on a table equipped with braked castors, facilitating easy transportation to different locations.

RESULT

Twenty20 Engineering successfully addressed the design challenges with a well-considered solution. This process yielded a comprehensive 3D CAD model, General Arrangement (GA) drawings and a detailed fabrication pack, empowering the client to manufacture the high-temperature testing system in-house.

This innovative system empowers the client to conduct essential high-temperature testing for their products on-site, ultimately leading to a faster time to market.
