Synthetic Sketches: The Role of Plastic Prototypes in Design

Rapid injection molding is crucial in prototyping projects that involve identical plastic parts. It enables product designers and engineers to test their designs in real-world situations to verify usability, safety, aesthetics, long-term feasibility, and performance. Essentially, prototyping is a crucial stage in product development where ideas are brought to life, and injection molding can help boost productivity at this point while mitigating issues around safety, functionality, and costs.

Injection molding is a cost-effective manufacturing solution for making a low volume of plastic prototypes. It’s quick and ensures consistent results for producing up to 100,000 parts. Moreover, it requires a minimal investment that helps designers save money.

How it works

Various stages are involved in rapid injection molding for prototyping:

• An idea for a part or product is shared with the manufacturer.
• Manufacturers will work closely with designers and engineers to visualize the design with 2D sketches and 3D models.
• After finalizing the design, the manufacturer makes a custom plastic injection mold based on the drawings and models. This mold is usually made of stainless steel or aluminum.
• Plastic injection molding commences to produce the parts.
• The prototypes are tested and set for approval.
• If there are no changes, the same mold and materials can be used for end-use production.

How Plastic Prototypes Benefit Design

Rapid injection molding simplifies prototyping by delivering custom single-unit orders for quality validation and testing. This helps identify flaws sooner rather than later so designers can improve their design and the finished product’s safety, aesthetics, and performance.

Additionally, plastic prototypes made with injection molding help customers make accurate estimates of manufacturing timings, production costs, and staffing for the product’s full run in the future. In turn, the customer can plan their budget and timelines.

Service providers work closely with engineers and designers to ensure injection molding is best for their projects. They can check which machines and injection molding techniques are suitable for the design and conduct test runs before committing to the entire order. Quality control and testing can be part of the project from the start, allowing designers to make improvements sooner to prevent small mistakes from becoming major issues.
