Our services are not limited to rapid prototyping development, we provide one-stop service from prototype manufacturing to final production, ensuring that your products can seamlessly transition from the concept stage to the market.
Before shipment, we provide OQC reports upon request. If needed, we can provide additional documents on material certificates, inspection reports, certificates of conformity, etc.
We have experts and testing equipment to provide full-scale testing, and we can provide CMM reports or 3D scanning reports upon customer request.
Brightstar has a complete ISO quality management system, proactively handling customer quality issues from the initial communication, providing cost-effective and reasonable suggestions from design, materials, production processes, manufacturability, etc. Once your order is confirmed, we will conduct a comprehensive design for manufacturing (DFM) review to point out any issues that our engineers think may affect the quality of your parts. We are able to share inspection data with you in real time so that we can work together to solve any quality issues you may encounter during production.
Brightstar is ISO 9001:2015 certified. We implement an ISO-standard quality management system to ensure that each prototype undergoes rigorous quality checks. We will also work with you to develop quality standards and conduct regular reviews during the development process. We will provide a detailed quality report after the prototype is developed.
Almost all engineering plastics and metal materials can be processed, ensuring the consistency of prototype parts and mass-produced parts, as well as high dimensional stability, high processing accuracy, and high repeatability. CNC machined parts are far superior to 3D printed parts in terms of accuracy, strength, surface finish and material availability, and the original properties of the material can be guaranteed.
The materials used for vacuum die-casting include polyurethane resin polymers and engineering plastics, such as ABS, PMMA, PC, PP, PA, etc. Cast parts can range from clear, translucent to colored, and from soft rubber to hard plastic. This vacuum equipment can accommodate molds with a size of 2.0M*1.2M*1.0M. Vacuum casting can be used to closely simulate the final injection molded part or finished product and is ideal for low-volume/short-run production. For complex structures, usually one mold can only produce 12 or even 10 castings.
CNC machining, vacuum casting, sheet metal, 3D printing, rapid tooling and injection molding, surface treatment services.
We provide a variety of material options. We can process more than 200 types of metal and non-metal materials. We will recommend the most suitable material based on your product requirements and budget. The impact of different materials on cost and performance is significant, and we'll explain these in detail and help you make the best choice.
Maximum part size that can be processed by CNC: 2000 x 1200 x 900 mm (sometimes need to be divided)
We will recommend the most suitable rapid prototyping technology based on your product design and functional requirements. We will also explain the advantages and limitations of each technology to help you make an informed decision. Generally speaking, 3D printing is suitable for complex prototypes, while CNC rapid prototyping is more suitable for high precision and strength requirements
