Industries Commonly Use Prototype Assembly

Creating high-quality prototypes to demonstrate your product’s design is essential for your success. But when looking for a prototype manufacturing company to work with, it’s important to find one that offers specialized services and capabilities that will help you achieve your product development goals. Depending on your needs, these capabilities may include 3D printing, CNC machining, injection molding, assembly, finishing and more.

A prototyping company must be able to offer a variety of technologies and methods to accommodate different requirements, from quick proof-of-concept models to detailed engineering prototypes for production-ready designs. The type of prototype you need will depend on the stage of product validation and testing you’re in. For example, you might need a prototype that looks like the finished product for visual evaluations, or an engineering-quality model to test for manufacturability and durability.

The manufacturing process can be complicated, and you’ll want a partner with the experience and expertise to deliver on your project goals. Look for a prototype fabrication shop with an in-house engineering team and the ability to provide preproduction assistance, including validating your bill of materials, verifying component details for manufacturability, functionality and regulatory requirements, and design engineering.

To ensure that your engineering model is a accurate representation of the final product, it must be durable enough to withstand repeated use and handling. High-fidelity prototyping processes such as multi-jet fusion can create rugged parts that are suitable for functional testing, short-run production and other applications. For instance, a simple plastic prototype could be made with injection molds whereas a complex mechanical prototype may require specialized 3D printers or CNC machines to fabricate custom parts and ensure accurate performance.

What Types of Industries Commonly Use Prototype Assembly?

Injection molding is a popular technology for producing functional prototypes and end-use parts, particularly when the final product must be made from plastic. This method is commonly used in the consumer electronics, medical and automotive industries for functional prototypes and end-use parts that are designed to be highly detailed.

For complex products with mechanical and electrical components, you may need to make a works-like prototype that emphasizes the functional features of your product without necessarily mimicking its final appearance. This type of prototype is ideal for testing and evaluating the product’s mechanical, electrical or software aspects.

Moreover, the repairability of prototypes is significantly influenced by the availability of resources and expertise. In research and development settings where rapid iteration is crucial, having in-house capabilities for repair can be invaluable. This might include access to a range of materials, adhesives, and repair tools, as well as personnel skilled in various aspects of prototype construction and repair. Conversely, in settings where such resources are limited, outsourcing repair tasks or creating a new prototype might be more practical solutions.

An additional consideration is the cost associated with repairs. Repairing a prototype assembly can sometimes be more expensive than creating a new one, especially if the damage is extensive or if specialized components need to be sourced. This cost-benefit analysis often dictates the decision-making process in prototype development. Companies must weigh the costs of repair against the time and expense involved in producing a new prototype, considering factors such as the stage of development and the urgency of the testing phase.
