HLH Prototypes offers an array of services and products through prototyping and contract manufacturing. The company uses state-of-the-art equipment and a team of seasoned engineers to produce parts for different clients. Based out of Shenzhen, HLH Prototypes is best known to provide bespoke prototyping, rapid manufacturing and product development. For years, the company has been providing its clientele with various prototyping and low-volume manufacturing services through 3D printing, vacuum casting, rapid tooling, CNC milling, injection molding, sheet metal and other finishing techniques. The engineers at HLH Prototypes are committed to providing best in line products at all times. The prototyping and manufacturing agency is moving to a new facility of 15,000sqm, which is not far from their current location.Nissan He, the Sales Manager, said, “At HLH Prototypes, we offer CNC rapid injection molding solutions for fast and quality parts. We build mold from steel or aluminium material depending on the specifications of the client and we obtain injection molds from real production material. We use standard mold bases to deliver precise and accurate mold. Besides, we can simplify the tool’s design to minimize the costs and lead times. We can use tailored solutions to obtain molded parts in rapid lead times.”
The company offers high precision CNC machining as part of its CNC prototyping. The CNC machining is a high precision and high-speed manufacturing process. During this process, various tools are used to cut away a billet of material or block. The removed material is used to create a product or part. At HLH Prototypes, they control tolerances to DIN-2678-1 Medium for plastics and Fine for metals. The company has invested in CNC capabilities to buttress their production diversity and capacity so they can run numerous jobs at once and be able to handle the varying needs of their clients. They offer their products at competitive prices.
Susie Su, the Sales Executive, said, “We provide exceptional die casting, which is suitable for manufacturing large volumes of metal parts for zinc, aluminium and magnesium. HLH Prototypes also provides precision die casting, which entails the manufacture of high-quality die cast tools along with post-process finishing and machining options. The die casting process is ideal for huge and complex parts that are repeatable and accurate. The process leads to low cost per part and delivers a variety of treatments and good surface finishes.”
The company produces production grade vacuum cast parts via their vacuum casting process and this does not involve production tooling costs and lead time. They can cast large and small parts including 2m long car bumpers, headphones and more. The entire vacuum vast process occurs in three phases. A master model is 3D printed or CNC machined. Liquid silicone is then poured to the master model, cured and dried and cut from the mold, leaving the cavity. Lastly, they pour resin into the cavity and do casting.
