Process selection for prototype production

Product development involves getting a concept into a form that could be manufactured. This process requires various decisions to be made regarding the manufacturing method that can affect the outcome significantly. The right process is equivalent to constructing a strong foundation of a high rise building; doing so guarantees firmness and sets pace for what is ahead.Get more news about Custom Keyboard,you can vist our website!

（1）Understanding Prototype Production

Before proceeding with process selection, it is vital to understand what prototype production entails. Prototyping connects an idea with its expression in reality, enabling refinement and design validation. Irrespective of whether it’s a physical product or software application, prototypes help stakeholders visualize, test, and iterate.

（2）Factors Influencing Process Selection

Several factors come into play in selecting the right manufacturing process:

1.Material Compatibility: Different materials need specific technologies of production application. For instance, the chosen method must support different properties of metal, plastic or composite.

2.Cost Considerations: The budget determines which technique should be used. While some may work well in terms of precision and speed, they might cost more. Striking the right balance between quality and affordability is crucial.

3.Time-to-Market: In today’s fast-paced business environment, time is money. Fast prototyping approaches like 3D printing have quick turnaround times making them ideal for meeting deadlines.

4.Complexity of Design: Complicated designs may afford sophisticated techniques like CNC machining or injection molding while simple ones would require less complex means.

5.Volume Requirements: The selected process will depend on how much goods are expected to be produced. Injection molding falls within such scaleable technologies mostly used in mass production as additive manufacturing caters for low volume needs only.

（3）Common Manufacturing Processes

1.Rapid Prototyping (3D Printing): 3D printing creates three-dimensional solid objects by depositing layers of material iteratively as opposed to conventional machining methods where part is created by removal of material from solid block which are then built up layer by layer. This method is flexible, cheap for small amounts and allows for more design freedom.

2.CNC Machining: CNC machining basically means removing material from solid blocks using computer aided control systems to get the intended shape. It’s precise, versatile, as well as permits complex geometry.

3.Injection Molding: Injection molding which involves injecting molten material into a mold cavity is commonly used in mass production. It’s efficient, provides high repeatability and ensures consistency across large volumes.

4.Vacuum Casting: By making use of silicone molds and resin casting, this technique can replicate parts. This technology suits low to medium volume production runs because of its outstanding surface finish and ability to reproduce minute details accurately.
