Choose The Right Plastic For Your Next Project

With thousands of plastics on the market, it can be a daunting task to decide which type is the best forĀ your next rapid prototyping or low-volume manufacturing project. When choosing which plastic to use,Ā there are going to be trade-offs between cost, moldability, surface finish, durability, strength and many others. The choice of plastic depends on […]

What Tolerances Can You Expect When Manufacturing Prototypes And Low-Volume Production?

When you supply your 2D and 3D drawings for a quotation on a new project, you must specify the dimensions for critical areas on your parts, as well as the tolerance that you require. Very tight tolerances are neither practical nor desirable in most instances, so letā€™s look at the tolerances that we specify at Star Rapid for most projects, why we do that and what it means for your parts.

Understanding Surface Roughness for Product Development

Surface roughness is often described by the term Ra but many of our clients are unsure about what this means, how itā€™s measured and why itā€™s important to their productā€™s designs. So here weā€™d like to remove any mystery so youā€™re better able to specify exactly the type of surface roughness you want and need […]

What are the Top Passivation Techniques?

What Does Passivation Mean? Passivation means to alter the chemical structure of a metal at or just below the surface, so that itā€™s more stable and doesnā€™t want to react with other elements in an undesirable way. There are several different manufacturing processes that we routinely use to passivate the surface of a part. The […]
