What is Plastic Rapid Prototyping?

Plastic rapid prototyping is a product development method that uses advanced manufacturing techniques to quickly produce plastic components for testing and evaluation. It allows engineers and designers to create multiple iterations of a part in a short time, facilitating hands-on review and refinement before moving to production. The process is characterized by its speed, affordability, and ability to mitigate risks by eliminating financial and time constraints associated with traditional manufacturing.

Rapid prototyping provides critical insights into design performance, helping engineers make informed decisions. Unlike final products, prototypes may not have the same durability or finish but are essential for validating form, fit, and function. Common processes include 3D printing, CNC machining, silicone molding (vacuum casting), and rapid injection molding.

Benefits of Plastic Rapid Prototyping

Plastic rapid prototyping offers numerous advantages for product development:

  • Speed: Prototypes can be produced in 1-7 days, accelerating design cycles.
  • Cost Efficiency: Low-cost processes reduce financial risks during testing.
  • Design Flexibility: Test multiple designs and materials simultaneously.
  • Risk Mitigation: Identify and address design flaws early.
  • Material Versatility: Choose from a wide range of plastics like ABS, PEEK, and Nylon.
  • Improved Product Quality: Iterative testing leads to better final products.

Applications of Plastic Rapid Prototyping

Our plastic rapid prototyping services support a variety of industries and applications, including:

  • Automotive: Interior components, dashboard parts, and functional prototypes.
  • Medical: Device housings, surgical tool prototypes, and biocompatible parts.
  • Electronics: Enclosures, connectors, and consumer device components.
  • Consumer Goods: Product casings, packaging prototypes, and aesthetic models.

Our Plastic Rapid Prototyping Processes

Kesu Hardware offers a range of rapid prototyping processes to meet diverse project requirements. Each method is optimized for speed, precision, and cost-effectiveness, allowing us to deliver high-quality plastic prototypes tailored to your needs.

Silicone Molding (Vacuum Casting)

Silicone molding, also known as vacuum casting, is a cost-effective and fast method for producing small batches of plastic prototypes. It involves creating a silicone mold from a master prototype and injecting liquid plastic to form parts with excellent surface finish and detail.

  • Process:
    1. Create a master prototype (e.g., via CNC machining using ABS).
    2. Produce a silicone mold around the master (dries in ~8 hours).
    3. Inject liquid plastic into the mold and cure.
    4. Remove the part; each mold supports ~20 parts.
  • Materials: ABS, PP, PC, PMMA, POM, soft rubber, silicone rubber, heat-resistant materials.
  • Lead Time: 3-7 days.
  • Advantages: Low cost, high accuracy, suitable for small batches.

CNC Machining

CNC machining is a versatile process for plastic rapid prototyping, offering high precision and excellent surface quality. Our advanced 4-axis and 5-axis CNC machines ensure accurate replication of complex geometries, making it ideal for functional prototypes.

4-Axis CNC Machines20AutoCamD600 x L1200 mm
3-Axis CNC Machines50-1500 x 800 mm
  • Tolerances: ±0.01 mm for linear dimensions, ±0.02 mm for holes.
  • Lead Time: 3-5 days.
  • Advantages: High accuracy, excellent surface finish, suitable for complex designs.

3D Printing

3D printing is a popular choice for plastic rapid prototyping due to its speed and affordability. We offer multiple 3D printing technologies to suit different project needs:

  • Stereolithography (SLA): High-resolution parts with smooth surfaces.
  • Selective Laser Sintering (SLS): Durable nylon prototypes with complex geometries.
  • Multi Jet Fusion (MJF): High-strength parts with fine details.
  • Digital Light Processing (DLP): Fast production of small, detailed parts.

MJFNylon2-4 days
DLPResin1-3 days

Plastic Injection Molding

Plastic injection molding is ideal for producing high-quality prototypes that closely resemble final production parts. While typically used for mass production, we offer rapid injection molding for prototyping with quick turnaround.

  • Process: Inject molten plastic into a mold using an injection molding machine.
  • Materials: ABS, PP, PC, PMMA, POM, Nylon.
  • Lead Time: 7-14 days (including mold creation).
  • Advantages: High repeatability, suitable for complex shapes.
