One of WayKen’s specialties is vacuum casting technology. But is this product right for your design idea? There are actually many applications for vacuum casting and plenty of reasons why you might choose to use this particular method of prototyping and production. Here are a few facts about the technology that you should consider before choosing this method.

Vacuum castings are the metal parts that are produced by the vacuum casting method. They are different than typical investment castings due to the technique that is used to create these metal parts. The process begins by placing a two-piece mold in a vacuum chamber. The vacuum then draws the molten metal into the mold. Finally, the casting is solidified in an oven and the mold is removed in order to release the final product.

What are the ways in which you can use a urethane cast part or product? Market testing, clinical trials, pre-production focus groups or even low volume production runs are all great uses of this technology. Customers who are looking for an edge that helps speed them through product design and functionality tests should look into vacuum casting technology. These castings also offer excellent optical clarity, high impact strength and flame redundancy.

Vacuum casting is widely used to create urethane casting parts or finished products. This procedure closely simulates final injection-molded parts or finished products in a way that is both inexpensive and fast compared to metal tooling. Parts can be delivered in days. Short runs can be completed in only a few weeks.

Some of the most common ways our customers take advantage of these castings are through short run productions, particularly with industrial design models. But these kinds of casting also work well with visual and aesthetic models. You can present this to a focus group with great results. If you want to study color and texture, this could be your best technology. Sales samples and other market study models are also possible.

Here is a question that designers need to focus on: How could designers improve their CAD files to make their vacuum cast prototype more successful? The wall thickness of a part is crucial, especially with vacuum casting. They should be the same thickness as the final part or product is intended to be. Keeping undercuts to a minimum is very important in vacuum casting. Large undercuts can create issues when removing them from the mould. While this is manageable it can be problematic and give unsatisfactory results. Having the correct tolerances for interlocking parts is vital. If, for example, one part of the part or product has a hole with a tolerance of 10, the part meant to fit inside the hole must have a tolerance of 9.9 so that it fits. It may seem obvious, but it’s quite common for both parts to have the same tolerance.

Vacuum Casting is known for its fast production of high-quality prototypes or end-use products. Silicone molding results in high-quality parts comparable to injection-molded components. This makes vacuum casted models especially suitable for fit and function testing, marketing purposes or a series of final parts in limited quantities.Vacuum Casting also lends itself well to a variety of finishing degrees, and we can match the finish you need for your parts.

The WayKen advantage offers a wealth of experience and depth of expertise. More than two decades of experience assures your company the highest quality and reliability for your short run or a mold. Castings can be created to accurately match your specified colors. We can create drilled, tapped insert moulded and over moulded parts. Our standardized procedures ensure that your part replication is accurate and consistent.
