In the fast-paced world of new product innovation, you need a partner you can rely on for rapid injection molding, rapid prototypes, and low-volume production.

Our online 3D printing service enables you to 3D print your custom part on demand. We offer five 3D printing technologies to transform your 3D files into plastic, metal, and elastomeric parts. With more than 100 3D printers, we have unmatched capacity that reliably delivers parts within days. In addition to a broad material selection, we offer several post-processing options to improve cosmetics or enhance mechanical properties.
Stereolithography (SLA) uses an ultraviolet laser that draws on the surface of liquid thermoset resin to create thousands of thin layers until final parts are formed.
Short production runs & prototyping
Strong prototyping parts in nylon or nylon glass
Functional prototyping & low-run production
Metal parts prototyping in steel or titanium
Rapid prototyping via CNC machining delivers high speed, high precision, and robust rapid part manufacturing solutions. You take a block or billet of material and cut away at it with a series of tools and drill bits, removing material to make CNC machined parts or products.
CNC milling cuts shapes out of a metal or plastic material blank that is usually flat, holding dimensions to tolerances as tight as 0.002.
Typically used to create a rounded surface, turning rotates the part when machining the desired shape, whereas milling rotates the tool.
Sheet metal parts are found almost everywhere and HLH can help you quickly and accurately make your enclosures, brackets, assemblies, weldments, cabinets, housings and other sheet metal parts and prototypes. Our MOQ is one and offer options for low/mid volumes.
How It Works – Sheet metal encompasses a wide range of processes to manipulate and shape sheets of metal into the required geometry. HLH use bending, laser cutting, punches, welding and other processes to manufacture your sheet metal parts and prototypes.
LEARN MOREVacuum casting or cast urethanes is a perfect solution for production quality parts without the cost or lead time required for production tooling.
At HLH we can cast parts as large and small, everything from headphones all the way up to 2m long car bumpers. We have a massive range of materials available for your projects.
LEARN MOREAt HLH, we offer a rapid injection molding service. Rapid prototyping can also come in the form of injection molded parts. How? Rapid tooling (bridge tooling) delivers low volume production quality parts (up to 100,000) from production resins.
Fast and cost-effective process for creating aluminum or steel injection molds. Ideal for rapid prototyping needs or validating product concept for production.
