If you’re trying to bring a new product idea to market, there may be more than one manufacturing method that will suit your needs. Each of these processes used at Star Rapid has advantages for lead time, precision, start-up costs, volume and more.

Plastic Injection Molding

• 1~4 weeks to make injection vowin.cn/en/News/news1251.html' target='_blank'>vowin.cn/' target='_blank'>molding tools and dies
• Able to process thousands of thermoforming resins
• Requires careful attention to best design practices for making tools
• High reliability and repeatability
• Higher initial tooling cost, relatively low unit price
• Best suited for high volumes of mass-produced commercial and industrial parts

CNC Machining

• No hard tooling necessary
• Most accurate and precise method for close tolerances
• Hundreds of metal alloys and hard plastics to choose from
• Cutting programs can be easily and quickly modified
• Suitable for rapid prototypes and production
• Fast set-up and turnaround times
• No limitations of volume
• Best for angled / beveled faces, flat surfaces, turned parts, tapped and threaded parts

Vacuum Casting

• Silicone mold tools are inexpensive
• Surface finish quality is excellent
• Many casting resins available that mimic plastic injection molded parts
• Requires a master pattern for forming molds
• Suitable for prototyping or end-use parts in small volumes
• Best for quick turnaround plastic parts with production quality look and feel

Pressure Die Casting

• Requires tools and dies
• Aluminum, magnesium, zinc
• Excellent dimensional stability and surface quality
• Best for large volumes of metal cases, enclosures and housings

Metal 3D Printing

• No tooling necessary
• Programming and set-up is relatively fast
• Most parts require post-machining and finishing to achieve final dimensions
• Low volume, high-value parts
• Best suited for lightweight, strong, highly complex metal shapes that cannot be made conventionally
