Selective Laser Sintering

Selective Laser Sintering (SLS) uses an infrared laser to sinter powdered material, typically plastic, metal, ceramic, or glass, binding the material together to create a solid structure. SLS builds parts by fusing material layer by layer from the bottom up, without the need for additional support structures. Among several common 3D printing technologies, it has the highest material utilization rate and is relatively cheap.

Prototype Preparation

Create the original prototype first using CNC machining or 3D printing. It is essential to ensure that the prototype is accurate, clean, and free of oils or contaminants.

Insert molding

Insert molding is like overmolding, but the base part doesn't have to be plastic or made by injection molding. For example, it can add a plastic coating to a metal part. It's often used for tools like scalpels, where a metal blade is embedded in a plastic handle, or for parts with bushings, clips, and fasteners placed inside the mold.

Stereo Lithography Appearance

Stereo Lithography Apparatus (SLA) uses an ultraviolet laser beam to selectively cure a polymer resin layer by layer to create objects. It is suitable for making fine parts, and the surface quality is smooth. SLA always requires a support structure. The material is usually a photosensitive resin.

Silicone Mold Making

Hang the master model in the casting box using plastic rods as gates and vents，pour liquid silicone around the prototype, ensuring no bubbles are trapped. Create a vacuum environment to remove any potential air pockets. Place the filled mold in an oven and cure it for 8 to 16 hours (depending on the mold's volume) at a temperature of 40°C. Once the silicone mold is fully cured, cut open the casting box, remove the prototype from the silicone, and the silicone mold is ready for use.

Selective Laser Melting

Selective Laser Melting (SLM) harnesses the power of focused laser energy to fuse fine metal powders, layer by layer, into solid structures directly from digital blueprints. It stands out for its remarkable capability to transform metal and superalloys into complex, high-strength components with unparalleled precision. It is particularly suitable for aerospace, medical, molds, automotive parts and other fields.

Vacuum Casting with Material Selection

Select the appropriate casting material according to the requirements (such as polyurethane resin). Inject the liquid material into the silicone mold under a vacuum environment to ensure uniform filling and minimize air bubbles. Place the silicone mold into a constant-temperature oven, preheat it to 60-70°C, and cure for 30-60 minutes.

Standardized management

Adopt advanced management concepts, establish clear work processes and operating standards, cultivate a skilled, professional and efficient team, and improve production efficiency and quality.

Customer First

With customer needs and satisfaction as the core, optimize production plans, processes, supply chain management, and strictly control costs. Continuous improvement, pursuit of excellent quality, to ensure maximum satisfaction of customer expectations

Quality First

Implement a comprehensive quality management system, from raw material procurement to finished product delivery, every link is strictly controlled to ensure high standards and consistency of products

Innovative Development

Build a learning organization and promote knowledge sharing. Collect and organize knowledge resources from various fields to provide employees with a growth platform. Encourage innovative thinking, create effective, better and more efficient methods and solutions, and enhance the core competitiveness of the enterprise

Overmolding

Overmolding is a process that creates chemically bonded multi-material components by adding a layer of injection-molded material onto an existing part. After the first injection molding process, the product is removed once it has cooled and is then placed into a second mold for a second injection. This causes the two plastic parts to be encapsulated together. It can be used to build layered components or to add a durable outer layer to existing plastic parts. This method is more cost-effective than separately manufacturing and assembling the parts.

Stamping Processes

Stamping processes involve using a punch press and dies to process metal sheets to achieve complex shapes and functions. These include:Punching,Embossing and Engraving,Flanging

5 Axis Precision Machining

5-axis CNC machining is a precise and efficient technology that can process complex parts with curved or intricate profiles in multiple directions at once. It completes most operations in a single setup, reducing repositioning and enhancing accuracy. Our Germany DMG MORI 5-axis machine meets high requirements for parts and is widely used in aerospace, automotive, medical prototyping, and other fields.

CNC turning

CNC turning is a precision process using a CNC lathe to shape parts by cutting bar or tube materials. It creates external geometries, internal holes, and threads. Brightstar offers comprehensive CNC lathe services for various materials like aluminium, steel, stainless steel, brass, and copper alloy, meeting diverse customer needs for cylindrical metal and plastic parts.

Demolding and Removing Prototype

After curing, open the silicone mold and remove the prototype. Then proceed with post-processing operations, such as deburring, painting, or others. Repeat this process to obtain more parts.
