Pressure die casting is great for manufacturing higher volumes of metal parts in aluminium, zinc or magnesium. HLH manufactures high quality die cast tools, offer precision die casting and post process machining and finishing options.
How It Works – Similar to injection molding but for metals, a mold tool is first manufactured by HLH’s highly skilled toolmakers and engineers. This is then installed on a die casting press and molten metal is injected under pressure into the tool cavity. The parts can then be finished in a range of ways including powder coating and anodizing.
I would like to congratulate you and your company with your service and prototyping quality. The communication with our company was very clear and constructive. The prototypes have a very good quality and the delivery speed are fantastic. With your prototypes we can communicate better and faster with our clients and give them a glance of how the product will look and feel like.Ing. Marc E.J. Van Strydonck Industrial designer

Hi HLH, I received the CNC prototypes last week and have spent the past few days assembling them. I would like to thank you and HLH for the work you have done CNC machining these parts and for delivering them to us as quickly as possible. I look forward to working with HLH again as new projects arise in the future.
We have always been very impressed by the level of service and quality provided by HLH. HLH gives our company a real competitive advantage in allowing us to provide our clients with quick and cost effective pre-production quality prototypes.
The prototypes arrived this morning and they look great. Thank you very much for your work on this project and your prompt and thorough communication. We will certainly be in contact again in the future.

We have worked with HLH Prototypes on a number of projects over the past year and have always been very satisfied with their services. We have produce with them high quality rapid prototypes for testing before tooling as a means to make sure we have the best design possible.
We will surely be continuing our working relationship with HLH Prototypes in many years to come
I would like to convey my sincere thanks to your company for all the work you have provided over the past year in helping to create parts for our models and the dedication you brought to our projects.
Not only was the work done to a high standard, and with considerable speed despite the harsh deadlines, but with the kindest and warmest of attitudes. I am delighted to have worked with your company, and would definitely recommend you to others.
Thank you very much again for your teamâ€™s speed and effectiveness in producing our RP molds. The quality in finish as always was fantastic especially the clear plastic parts.
Our engineers were just commenting on how the quality in the surface and spray finishing are superior to the models that we had received before from other China based RP houses in the past.
Like the previous years, we look forward to displaying your RP models as various international toy trade shows, where they have proven themselves in the past with strength and durability

HLH Prototypes. What canâ€™t they prototype?
We have had everything from soft rubber to hard plastics, various grades of aluminum to stainless steel parts prototyped via HLH to characterize the performance and gain high level of confidence on design months before actual verification parts and data is available. We have used many of their arsenals of processes from SLA, CNC mill, lathe, forming, wire-cutting, EDM, vacuum cast and my favorite – custom springs. Product development is so much more progressive and easier with HLH as your prototype partner.

Die Casting Tips
When it comes to any design, to achieve ultimate project success it is good to check your design against your chosen manufacturing process to see if any changes are needed. For die casting there are many things to consider to ensure you get a better quality of part.
Applying proper draft is crucial in die casting to ensure you get a consistent part without warpage or surface defects. The exact amount of draft you need to add depends on the part and tool design but get in touch early in the process and we can advise.
