Top 3 Reasons to Use Vacuum Casting for Rapid Prototyping

Are you looking for a cost-effective way to create production-quality parts fast? Vacuum casting may be for you. Also known as cast urethane, it is a great solution that can deliver production-quality parts without the typical lead time or the costs associated with production tooling. You merely have to partner with the right service provider that can provide a vast selection of materials and for your project. It’s possible to cast parts of any size, from headphones to lengthy car bumpers.

But is vacuum casting the best for your prototyping requirements? Mentioned below are three reasons to choose it:

1. Get high-quality production-grade prototypes

You may be building prototypes for now. However, if you want to analyze them better, they have to be sound in quality. Cast urethane parts are production-quality and detailed, no matter their size. That said, it’s essential to ensure the master model’s quality by verifying its high-resolution features and good surface finish.

2. More material options

Vacuum casting allows you to make prototypes from many different materials such as polymer resins, flexible elastomers, and stiff plastics. The parts can be transparent or self-colored, depending on your design. There is a good selection of curable and castable resins, which are as good as thermoplastics like PP and ABS. That means cast urethane parts can have similar mechanical and aesthetic properties to final, mass-produced products made of PE or ABS.

3. Save time

Vacuum casting saves a lot of time and helps speed up product development. Silicone molds are quick and easy to create and the cast urethane parts can be produced quickly in succession with one mold. You can get the parts quickly and hence you can start with functional testing and validation right away. It also lets you conduct quality assurance at the prototyping stage to determine if the parts are viable for certain applications before they go into final production.

Tips On Choosing The Right Prototypes Plastic Parts For Your Need

  Are you building a  prototype plastic part ? It's crucial to pick asuitable material, but that process can become intimidating as different plastics vary in durability, aesthetics, and strength. Even when prototyping, you’ll want to produce a production-grade prototype that lets you evaluate your product's performance in the real world. Here are some tips to reduce your guesswork in choosing plastics for your prototype.   Consider these critical factors.   Know the purpose of your part and its mechanical functions. You should also consider your manufacturing processes, such as CNC machining, injection molding, or 3D printing. Moreover, determine the quantity, the cost, and the lead times.   Explore commonly used plastics   Reputable manufacturers constantly update their selection of plastics, but these are the most common types you can consider for your  prototype plastic part :   ·         Acrylonitrile butadiene styrene (ABS): This is a strong material w

Rapid Tooling: A Perfect Speed to Market Product Development Solution

One of the greatest challenges that product manufacturers and designers face today is finding ways to speed up time to market. With consumer demands leaning toward rapid product development, manufacturers and product designers feel the pressure of having to churn out products in the fastest time possible. Just the same, new product development still requires a prototyping stage in order to ensure the feasibility of the product design, including its general shape and form, assembly, and functionality. Thanks to new technology, rapid tooling methods are becoming increasingly commonplace, enabling manufacturers to reap the benefits of much faster methods to create prototypes, which in turn speeds up product testing, final production, as well as its release into the market at large. Rapid tooling offers faster lead times of mere days instead of weeks or months, just like conventional manufacturing ways. Five to ten days is already a stretch when trying to get at least 50 prototype

Different Types of 3D Printing Prototypes

Additive manufacturing lets you build three-dimensional objects based on your digital drawing model. It creates a custom   3D printing prototype  by adding materials one layer at a time or by sintering or fusing powdered materials, depending on the method you use.   Technologies have come a long way and introduced more 3D printing methods to help you make prototypes quickly, accurately, and cost-effectively. Here are the most common types you may want to know. Stereolithography SLA 3D printing is among the oldest and most versatile additive manufacturing technologies. It builds the object layer by layer using a photocurable resin cured with an intense UV laser in the build platform. The result is a  3D printing prototype  with a good surface finish and optimum accuracy to the CAD. The process involves support structures to keep the material in place while printing, but these are removed afterward. This technology is ideal for making aesthetic models and bespoke or low-volume pr
