Divided into six zones, the 12000sqm facility provides end-to-end metalwork, engineering, prototyping, tooling and production solutions. The facility is equipped with cutting edge technology and complies with ISO 9001:2015, ISO 14001:2015, IATF 16949, and ISO/IEC 27001:2013 quality management standards. HLH Prototypes’ takes up each project with commitment, ensuring solutions as per the client’s specifications, schedule, and budget.

Jack Cheng, the tooling and injection moulding manager at HLH Prototypes, stated, “HLH Prototypes has carved out a niche for itself in the global prototype and contract manufacturing sector. Our status comes from the sheer variety of services that we offer to Aerospace & UAV, Automotive, Communications, Consumer Products, Product Development, Industrial, Medical, Robotics and Automation, and other industries. We offer a full continuum of prototyping services, including CNC Machining, Carbon Fibre, 3D Printing, Sheet Metal, Vacuum Casting and Rapid Injection Moulding. Customized low volume manufacturing solutions for Die Casting, Export Tooling, and more are also readily provided with a promise of quality and prices.”

Particular about quality, HLH Prototypes adopts a three-pronged quality control mechanism. In stage one, a team of experienced engineers conducts a full DFM to bring to the fore deficiencies in design and suggest improvements. The second stage is marked by the use of PIM Spectrometer to inspect materials for their quality and performance. The final stage takes place after manufacturing and before shipping, involving a Full QC inspection and report. Thanks to the quality control mechanism, the bureau can provide customer satisfaction guarantees, wherein any defected parts received by the client are replaced or reworked for free.

On Rapid Injection Moulding, Jack Cheng stated, “Prototypes are the real production materials or low/mid volumes of parts that are often required by industrial businesses. They are often cramped for time particularly when there is a need to swiftly market test new product iteration. Here, production tooling makes little sense, as it involves additional time and outlay. Rapid Injection Moulding is the best bet, offering superior, customized parts in real production grade materials in low lead times and at modest upfront investment. The flexibility factor is also there.”
HLH Prototypes has a pedigree in Rapid Injection Moulding. The bureau adheres to the best techniques to implement high-quality parts from real materials quickly. The moulds are built from either aluminium or steel, depending on the client’s project requirements. The use of standard mould bases is prioritized, which is an effective ploy to bring down costs and lead times. The bureau prefers SPI Finish B-1 600 Grit Paper to achieve the desired surface finish while restricting time and costs. Thanks to HLH Prototypes’ competitive pricing across all services, cheap injection moulding is always possible.
