Let’s show you the full process from design to prototype

Industrial Design

Industrial Design

Industrial Design (ID) is the professional practice of designing products, devices, objects, and services used by millions of people around the world every day.

Industrial designers typically focus on the physical appearance, functionality, and manufacturability of a product, though they are often involved in far more during a development cycle. All of this ultimately extends to the overall lasting value and experience a product or service provides for end-users.

Mechanical Design/Engineering Design

Mechanical design, which is also known as machine design or engineering design, is the process of designing effective parts or components for machinery. Those working in the mechanical design field study how mechanical components operate in various situations in order to create a reliable system. The major goal of mechanical design is to develop machinery designs that are safe and align with client specifications.

Engineering Design

Prototyping is an important stage to show how the design works, to verify the functions.
Some customer like to assembly it ,check it closely and give us feeback. We like listening and discussing every point about the prototype and design with them.

3D Scanning and Reverse Engineering

3D scanning is the process ofdigitizing a physical object into three dimensional space. The resulting STL file contains a digital blueprint with geometric coordinate positions. The resulting digital twin unlocks many digital engineering capabilities, including reverse engineering and inspection for dimensional analysis. That means if you lost the 3D data of a part, 3D scanning and reverse engineering is a good way to reverse the object into 3d data. Besides, if you want to manufacture a part  same as a part exsiting, the 3d scanning could help as well.

Our Product Development Serivece Make us Different

Our experienced design staff can design your enclosure for you, starting from anything from a rough description, to components and circuit boards. Customers use our Design Services when they’re too busy to take on the design work themselves, and wish to free up staff for other tasks, or who simply lack the resources or know-how required to design their enclosure. Our design staff’s speed and experience make our design services surprisingly cost effective, and you may save further time because their intimate knowledge of Protocase’s manufacturing capabilities virtually eliminates non-manufacturable features and resultant revision

Our R&D department established for prototyping and mold manufacuring. When found many years ago that many customer have excellent concepts but somehow could find no one to do the design job for them. That is pity, and is an obstacle for the cooperation between us.

Thousands of projects and prototypes have been done with the help of our designer. The stringent requirment of design from customer make us better.
