Rapid prototyping to manufacturing

CNC machining FAQ
Yes, polyurethane parts can be provided as a final product to an end user. While this process is often used for prototyping, customers also often use it as a bridge process to get a product to market while production processing is ongoing. For very specialized products, such as medical devices, this process is used for production because the very low upfront cost is attractive for short runs. The production quality appearance and the polyurethane developed for functionality make this process very suitable for end use.
Brightstar's in-house prototype finishing provides optimal post-finishing, including assembly and form fit, fastening and metal insertion, sanding and polishing, sandblasting and brushing, painting and printing. We also offer a variety of special surface treatments by working with quality surface treatment suppliers, including laser etching, anodizing, electroplating, chrome plating, chemical finishing, powder coating, and more. To provide customers with rapid simulation prototypes that are identical to the final product, we support one-stop surface finishing operations.
We are equipped with advanced DMG 5-axis machining machines from Germany. As the world's leading machine tool manufacturer, DMG MORI's five-axis gantry machining center is famous for its high precision and high stability. The DMG 5-axis CNC milling machine allows us to flexibly handle Your custom parts, whether simple or highly complex.
We do not provide design services, you are responsible for submitting 2D and 3D CAD drawings and we can then provide design for manufacturing (DFM) review and analysis upon receipt of your drawings.
No given set of tolerances is suitable for all processes and materials. In any case, the final tolerance of your part will depend on many factors, including but not limited to: part size, design geometry, material, surface finish.
Hostar's general tolerances apply to ISO 2768 (medium) for machining plastics and ISO 2768 (fine) for machining metals. Typically, we can maintain CNC machining tolerances between ±0.005 inches (±0.125 mm) and ±0.002 inches (±0.01 mm), and with fine machining, the tightest tolerance can also reach +/-0.005mm
Each manufacturing process is different, depending on part size, quantity required, and finishing requirements. Quality prototype parts can be made in 3-9 days. Rapid injection molding may take 2-5 weeks to complete. More complex parts or other special features take longer. As for shipping, most shipments under 200KG are shipped by air, which may take several days from China to Europe or North America, depending on customer requirements. Shipments over 200KG can be shipped by air or sea, or wherever land transportation is available.
There is no single answer to this question, but there are some rules that apply. For US customers, prototypes used only for development, testing, product evaluation or quality control purposes are allowed to be imported into the United States duty-free at the Most Favored Nation rate (US HTS number: 9817.85.01). Import duties vary greatly from country to country and depend on the type of goods being imported. Most countries in the world adhere to the international Harmonized System (HS) codes, which classify nearly all commercially traded goods.

Many fabrication and prototyping companies now also offer online services, making geographic distance no longer a barrier. Brightstar, a rapid prototype China manufacturer, we offer competitive prices and quick turnaround delivery, with custom CNC parts in just 3 days and 3D printing parts in 1 day, and delivered to you within 3-4 days by international express.
For rapid prototyping and regular production orders, our standard terms are Ex Works (EXW). This means that once the goods leave our premises, the customer will be responsible for shipping, customs clearance and all other related costs. We also offer Delivered at Work (DAP) terms for international express delivery DHL, FEDEX, UPS Express, and the customer is responsible for import duties and fees associated with international shipping. Customers can also choose to use their own shipping account if applicable.
At Brightstar, there is no minimum order quantity requirement. Our services can support you to scale from one-off prototypes to medium and large-volume production.
The time for rapid prototyping depends on the complexity of the project and the technology selected. We will provide a detailed timeline before the project starts and review it with you to ensure it meets your expectations.
We have a strict quality control process and an experienced team to ensure the quality of the prototype even under tight time frames.
