Case Studies

At Huapin, our experienced team make the best prototypes and precision parts for many companies in the world. We work with all kinds of engineers, product designers, and entrepreneurs from a wide range of industries like automotive,medical devices, aerospace, consumer & commercial products.

We can help you translate your design and invention blueprints into manufactured prototypes using our services such as CNC prototyping, Urethane Casting, and 3D printing. And we can manufacture your parts quickly so you can test the market before investing in tooling and producing larger quantities, using our short-rum manufacturing services such as Rapid tooling, Pressure die casting, and Sheet metal fabrication. 

Here are sample descriptions of our work we did for our customers, with details about how each prototype or part was made.

Precision machined trophies for Core77 Design Awards

Each year, the industrial design website Core77 hosts the Core77 Design Awards, where it “celebrates the richness of the design profession as well as the insight and perseverance of its practitioners.” Aimed at both students and professionals, the Awards cover everything from furniture to commercial equipment to packaging. One of the most unique aspects of the contest, now in its eighth year, is its trophies. These special prizes function as both traditional trophies and working molds, allowing winners to duplicate their trophies in plastic, wax or even something like chocolate. This effectively allows design teams to give an individual trophy to each member of the team — very diplomatic! For the 2019 edition of the awards, the responsibility fell to 3ERP to fabricate all 36 trophies, which we were able to turn around in just a few weeks. Here’s how we did it. 2-in-1 trophies Since the spectacular Core77 trophies

Xbox Controller Prototype

In October 2019, Microsoft began trials for its cloud gaming streaming service, Project xCloud. The service, which runs games on remote servers, allows users to play those games without dedicated hardware. Although xCloud will not run on a console, Microsoft has filed patents for new gaming controllers,  leading some to believe that the company will imminently release new joypads to be used with non-Microsoft devices like iPads and smartphones. Ahead of that potential release, the gaming fanatics at Yanko Design created their own xCloud controllers based on the Microsoft patents. Industrial designer Sarang Sheth brought the two-part design to life with a visual concept, and then gave 3ERP the exciting task of creating a physical prototype of the Xbox controller. We were only too happy to oblige. Fabrication We fabricated the controller using a combination of CNC milling, CNC turning and vacuum casting — processes we considered suitable for the complexity,

Customize Shoes for Lady Gaga

When rapid prototyping is mentioned, the first thing that pops up in our minds is always what it can do for industry. But rapid prototyping is also used for things we want in daily life. People are always looking for unique products to fit their own personal style. That’s why 3D printing services are becoming more and more popular, allowing everyone to get their own designs made for an affordable cost. Here is an example of how rapid prototyping can bring your own individual style from imagination into reality. This is a pair of shoes we did for Lady Gaga awhile ago. It is not just a concept model to review how it looks. It is also a pair proper shoes to wear in daily life. Our task is to make it safe & lightweight. Comparing with a few materials, our customer finally picked up polycarbonate. Instead of making it

Diamond Cut Lamborghini Model

This is an old project we did for UN in 2013. In order to stay within budget, we made it using SLA (stereolithography) and painted it black. The result we got was OK, but not brilliant. This is due to the limitation of the SLA process: the visible layers of the build process is the main problem. Recently, we came up with the idea to make this prototype using 5 axis CNC milling. in order to find a better solution for similar kinds of projects, meanwhile test out the accuracy and stability of our new machine. Challenges of This Project For this kind of model, it is very important to keep all the lines of the edges as sharp as possible. In some areas, the angle between the two surfaces is very large, almost 170 degrees, which means the join line is almost flat. To maintain these fine details is

Rapid Tooling for Tail Light Project

For this tail light project, we needed to fabricate a housing, reflector, light guide, bezel, outer lens and other components. The overall assembly size was about 600 x 400 x 150 mm, which is relatively large, and the customer wanted to test real materials. In this case, 3D printing, CNC machining or vacuum casting would not have worked; prototype molding was the only option. Can you imagine attempting to make prototype tools for over 30 components in just two months? Our customer desperately needed 200-300 sets of tail lights for testing, but mass production tools wouldn’t have been ready for eight months. They needed a solution to get good quality moldings by their deadline and at a much lower cost than production tools. How do we shorter the manufacturing time? Fully understanding the project – As a rule of thumb, fully understanding the project at hand can help save a
