HLH Prototypes manufactures parts to precision at highly competitive rates. They specialize in product development, rapid manufacturing, and prototyping services. They have state-of-the-art facilities with innovative infrastructure and equipment to produce quality and robust parts for use in commercial and industrial applications. Their engineers and technical staff are dedicated to ensuring quality production and delivery in areas of rapid tooling, vacuum casting, injection molding, rapid prototyping, and 3D printing and much more. HLH Prototypes is relocating to a new improved facility not far from their current location.

Speaking about 3D printing, Susie Su, the Sales Executive said, “Our 3D printing ensures high precision, fast and accurate drawing parts that are robust and with excellent surface finishes. You can use our 3D printing for quick fit, functional models or patterns, and low volume production parts, among others. The SLS and SLA techniques used in 3D printing delivers accurate aesthetic models and functional prototypes. We have vast experience in 3D printing and will always produce high precision parts every time."

HLH Prototypes provides sheet metal prototype through rapid prototyping and rapid production services. They use both manual and tooled manufacturing techniques and processes to ensure highly complex parts. Their processes include shearing, bending, wired cutting, stamping and CNC folding, punching, counter-boring and countersinking to produce brackets, assemblies, enclosures, weldments, cabinets, housing and more. Their process provides options for low to mid volume to deliver accurate and versatile parts. Various sheets of metal can be manipulated and shaped into required geometries.

Speaking about CNC Machining, Nissan He, the Sales Manager said, “At HLH Prototypes, we produce strong and durable CNC machined prototypes that can withstand mishandling because of their excellent surface finishes. During CNC machining, the tooling time is eliminated to deliver parts at cost-effective rates. Our surface finishing delivers colored parts that help to extend them from one SKU to multiple SKUs by offering them in different looks and feels. The part designs can be modified at no additional costs.”

HLH Prototypes delivers vacuum cast parts without the need for lead time and production cooling costs. The company can cast both large and small parts including 2m long car bumpers, and headphones, among others. The vacuum cast process comes in three stages including the master model, silicone tool and castings to deliver production-like parts that are self-colored. Vacuum casting is a process with low upfront investment, making it ideal for low volumes, market testing, rapid iterations, and many other applications.
