Vacuum Casting Precess
Vacuum casting (also known as urethane casting) is an economical alternative to low-volume injection molding of plastic parts and can be used to closely simulate final molded parts or finished products. Generally, molds are made from silicone rubber and use CNC machining or SLA part as a master pattern. These molds duplicate intricate details and textures and give consistent finishes from one part to the next. You can get production-like results including mechanical traits, wall thickness, colors, and surface finishes.




Company Profile








About DDPROTOTYPE
At DDPROTOTYPE, our focus is on providing you with the finest services in rapid prototyping, rapid tooling and low-volume manufacturing. Our international team of engineers and technicians are dedicated to making your custom parts using the most advanced equipment and techniques including multi-axis CNC machining , vacuum casting, sheet metal fabrication, plastic injection molding. We’re here to turn your ideas into reality quickly, accurately and at a great price.




Vacuum Casting Materials
Urethane resins are polymers with a wide range of properties and use. DDPROTOTYPE offers various urethane materials to meet your applications, including Hei-Cast from Japan and Axson from France. Materials with certain properties are similar to engineering production plastics, such as ABS, PMMA, PC, PP, PA, and so on. Casting parts can be varied from transparent, translucent to colored, and from soft rubber to hard plastic. Various materials contain those impact-resistant, high-temperature resistant (120℃) or fire-resistant (UL94-V0), glass-filled resins, and different hardness silicone.


Vacuum Casting Parts


Vacuum Casting - Urethane Casting
DDPROTOTYPE is fully capable of handling your vacuum casting and silicone molding needs. With years of expertise in the field, we can fabricate your plastic parts to the highest standard, as well as cost-efficient and with fast turnarounds.Vacuum casting is a great method to make rigid or flexible parts, and is ideal for high quality prototypes, function testing, concept proofing and display demos. Urethane casting parts can be made from a few to hundreds as required.

FAQ


What makes DDPROTOTYPE ’s vacuum casting service unique?

Our vacuum casting service is noted for its exceptional quality and speed. Our skilled technicians combine decades of experience with the latest technologies to produce exceptional prototypes and engineering models quickly. We can also further enhance your parts with a suite of finishing services including machining, media blasting, printing, painting and more.

Can DDPROTOTYPE provide design services, industrial design support or product development support as an extension of its vacuum casting services?

Yes. To supplement our vacuum casting services, we offer an expanded service geared for design-for-manufacturing support. While we once reserved this service only for approved orders, we now provide it to all incoming RFQs. We also offer light assembly services to meet your needs.

What are DDPROTOTYPE ’s quality standards for its vacuum casting services?

To ensure the highest standard of quality for all of your finished parts, our team adheres to a strict quality control process. This starts with the verification and testing of all materials. During production, we meticulously control temperature, humidity and other processing conditions to maintain the highest degree of consistency in your parts.

How do I get a quote for DDPROTOTYPE ’s vacuum casting services?

We make it easy to get a fast quotation. Simply upload your CAD files and product details and we’ll send you a free quotation within 24 hrs. or less.

What are the limitations of vacuum casting?

There are some limitations to the vacuum casting process. Developers need to use good design practices to ensure enough draft so the part can be released. For the same reason, avoid undercuts, deep ribs, bosses and other features that will destroy the relatively soft silicone mold when it opens.

What keeps the mold together in vacuum casting?

When our technicians cut the mold open to remove the master pattern, they make a sawtooth pattern on the cutline that acts like a key. This helps the mold to be resealed in the correct orientation for pouring resin. The mold merely needs to be taped and stapled shut to avoid any leakage during the pour.

Why would I choose vacuum casting over injection molding?

Vacuum casting is a more affordable alternative to IM, especially in low volumes. It also offers unique advantages like an excellent surface finish.

Can I make production-quality parts using vacuum casting?

Vacuum casting is best for making visually impressive prototypes, but it can also be used for non-mechanical end-use parts like cases and covers.

What happens to the silicone mold(s)? Can I keep them?

The silicone molds used in vacuum casting have a short lifespan, typically around 20 moldings, so we dispose of them after use.

If you wish to keep the 3D printed or CNC machined master model, talk to us directly.
