A Quick Introduction to Vacuum Casting

There are many ways to build a prototype these days, but not all of them may be economical for you. If you need production-like parts for low volume production or prototyping with a low upfront investment, you might want to consider vacuum casting in China. The process is also known as urethane casting, and it will deliver production-quality parts without the usual lead times and costs associated with production tooling. With the right service provider, any part regardless of size can be created. That also makes the process versatile for creating many different types of products, from car bumpers to headphones.

 

Know how it works

 

Reputable rapid prototyping and manufacturing specialists offer a wide range of materials that can be used for vacuum casting in China. No matter your project, urethane casting follows three stages:

 

Stage 1: Master model – This is either SLA or SLS 3D printed or CNC machined

Stage 2: Silicone tool – At this stage, liquid silicone is poured around a master model and left for curing. Once it is dry, the master is taken from the mould, leaving a cavity.

Stage 3: Casting – Resin is poured into the cavity, and the production-like replica is made.

 

Benefits of vacuum casting

 

This technique will produce self-coloured parts and rubber-like parts for low volume prototyping and manufacturing requirements. You will get production-like parts, which can be practical when understanding how your product works or functions during the prototype stage. Vacuum casting in China makes it possible to recreate tens of parts quickly for in-house testing, as well as for market.

 

High precision results

 

Silicone ensures that the end product is highly detailed and exact to your specifications. Thus, the final product is similar to the original one, which means you get high-quality results. Moreover, the use of resin gives you freedom to pick the best material for use in making the final product. This way, you have more options in terms of hardness, rigidity, and flexibility!

Advantages of Direct Metal Laser Sintering in Rapid Prototyping

Image
Most people associate 3D printing with making plastic parts for prototyping or end-use purposes. But with advancements in additive manufacturing technologies, it is now possible to 3D-print metal parts using the direct metal laser sintering process. Known as DMLS for short, direct metal laser sintering is a well-known industrial additive manufacturing technology similar to selective laser sintering (SLS) . However, it builds parts one layer at a time by fusing metal-based powders with a high-power laser. As such, it can realize complex designs that would otherwise be difficult to make with machining and other manufacturing technologies. Plus, it can build parts without support structures, so you spend less time post-processing. DMLS 3D printing can benefit your prototyping process in many ways. Given its speed, reliability, and cost-efficiency, it can speed up your product development and time to market to get ahead of your competition. Besides that, direct metal laser sintering c

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

Understanding the Advantages of Rapid Injection Molding

When you need prototypes or parts fast, consider having them done via rapid injection molding. The manufacturing method is particularly useful for low to mid volume production where rapid tooling might be inefficient or incapable of producing the exact results you want. Chinese injection molding companies are trusted by discerning manufacturing companies with tight deadlines and the need to test a new product in the market. With rapid injection molding, you can get the parts done quickly and efficiently using real materials. Rapid injection molding used to be reserved for mass production, where large companies would turn to manufacturers in China for an injection mold . However, it can actually also be flexible for creating high-quality prototypes. Moreover, it can be done as injection molded parts. Rapid tooling or bridge tooling is capable of delivering quality parts for low volume production requirements of up to 100,000 pieces from product resins. Think of it as an end-use
