Producing production-quality parts often requires longer lead times and incurs high costs, making it a challenging and costly process. However, by partnering with HLH Proto, you can overcome these challenges and achieve cost-effective solutions without compromising on quality. HLH Proto offers vacuum mold casting services, an efficient manufacturing process that can produce a diverse range of parts, from small headphone components to large car bumpers. Utilizing a variety of materials, including plastics and metals, HLH Proto’s vacuum mold casting can meet even the most stringent requirements.

Why HLH Proto?

Vacuum mold casting is a process that is greatly dependent on a custom model. The quality of the model is crucial to the success of the casting process, and it can be built using advanced manufacturing technologies such as SLA 3D printing or CNC machining, depending on the requirements of your design.

At HLH Proto, we specialize in both SLA 3D printing and CNC machining, providing our clients with a comprehensive solution for creating the perfect master model for their vacuum mold casting project. You don’t have to work with multiple companies for your prototyping needs.

The process

After making the master model, liquid silicone will be poured around it and cured. Once dry, the model is cut from the mold, leaving the cavity. Then, your chosen resin will be poured into that cavity. One of the best things about vacuum casting is it creates a production-grade replica that you can use for testing or end-use purposes.

More benefits

Vacuum mold casting is one of the most versatile for low-volume prototyping and end-use production. With HLH Proto, you can accomplish rapid iterations and market testing faster and cost-effectively. Vacuum casting is also a preferred method of producing self-colored rubber parts with a low upfront investment. Additionally, molding is easier to scale, especially when making identical parts.
