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 as new projects arise in the future.

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.
