Need to produce a small batch of complex prototypes? Vacuum casting could be the ideal manufacturing method for you. Also known as urethane casting, the process eliminates the gap between end-use production and rapid prototyping.   Vacuum cast parts  are precise, high-quality, and consistent, allowing for swift product development. Moreover, it empowers your design and engineering team to maintain the highest production standards while bringing concepts to life at a reasonable cost.   Vacuum casting is among our specialties here at HLH Proto, and in this blog, we will share how our service can deliver cast urethane parts quickly and cost-effectively.   Faster than injection molding   If you only need a small quantity of high-quality rubber-like or plastic parts, we recommend vacuum casting over injection molding. It’s faster and more cost-effective because it doesn’t involve production tooling. At HLH, we can produce  vacuum-...

Once primarily known for producing aesthetic plastic models and prototypes, 3D printing has evolved significantly due to technological advancements. It is now a versatile tool capable of creating robust, durable parts for testing and end-use components across various industries, including the airline sector. Here at HLH Proto, we work closely with many companies in the aircraft industry and deliver our  metal 3D printing  solutions for their  rapid prototyping  needs.   By embracing 3D printing, airline companies are opening new possibilities to revolutionize the design, prototyping, and manufacturing of custom components. They acknowledge the game-changing benefits of technologies like direct metal laser sintering (DMLS) in their ability to innovate, improve safety, enhance performance, and reduce costs. From environmental sustainability to cost efficiencies, streamlined production, and lightweight designs, 3D printing is ...
