Heatgun Redesign

Project context

As part of my Industrial Product Design studies, I was tasked with redesigning a heat gun based on a specific geometric form. The challenge was not only to create a functional and ergonomic design, but also to ensure that the product could be produced using injection molding.

Approach

Following the IPO design process, I started with research into injection molding requirements such as tolerances, draft angles, and injection points. Through concept exploration and CAD modeling in SolidWorks, I iterated on various design directions until I found a suitable solution. After several refinements, I chose a curved cone geometry as the base form, balancing aesthetics, ergonomics, and manufacturability.

Tools & Techniques

• IPO design process

• SolidWorks CAD & injection molding simulations

• Geometric form exploration

• Manufacturability analysis (tolerances, draft angles, injection points)

Outcome

Reflection

The result was a fully injection-moldable redesign of the heat gun, validated through simulations in SolidWorks. Although the product was not physically produced, the design met all criteria for manufacturability and functionality.

This project gave me deeper insight into the technical challenges of designing for injection molding. I strengthened my skills in CAD, learned to apply tolerances and draft angles effectively, and developed a better understanding of how to translate complex geometry into a producible product.
