X Rapid Technologies, an expert silicone prototyping company, offers a vacuum casting service that is high in efficiency, accuracy, and consistency.

What is Vacuum Casting and how does it work?

X Rapid Technologies is the best silicone molding company that develops high-quality silicone prototyping parts out of vacuum casting to provide accurate part replicas and consistent mechanical properties.

Nowadays, silicone molding company are offering high-quality silicone prototyping parts out of vacuum casting to provide accurate replicas of different models. Silicone prototyping is the silicone mold best from the product prototype using vacuum casting to produce the same replica. Vacuum casting uses similar materials such as ABS, PU, transparent PU to make the same parts in the vacuum environment. Silicone prototyping parts using vacuum casting can produce the same strength and hardness as mass production products and with the same colors as well. X Rapid Technologies is the top silicone molding company that offers various high-quality silicone prototyping parts with vacuum casting.

What Is Vacuum Casting?

It is a casting process that uses a vacuum to extract liquid materials and turn them into mold. Usually, if the air entrapment is having a problem with the mold, then this method is used. Also, if there are any intricate details and undercuts on the mold, you can use this method to fix it. Silicone molding company use rapid prototyping where the plastic sheets are preheated. This is why it's often called thermoforming. The preheated materials get dropped in an automated vacuum casting machine to make them soft and pliable.

How does a silicone molding company use vacuum casting to make silicone prototyping parts?

Silicon molding company follow the following steps to make silicone prototyping parts or rubber parts:

Step 1) Making master designs:

First, you need to create a master model of your CAD designs. The master will be a 3D model made by CNC machining or with 3D Printing. After that, the next move is to make a silicone mold of the model.

Step 2) Make the mold:

In this step, Casting molds are made from liquid silicone. Here, casting boxes are half-filled with silicone, and then the box gets heated up until the silicone is completely cured. Leave the cure inside an oven for 16 hours. Take it out and let it dry. After that, cut the mod in half and remove the master.

Step 3) Make the parts:

Lastly, pour the casting resins into the empty cavity and make an accurate replica of the master model. You can create more than 20 replicas with ease.

Why choose Vacuum Casting?

Silicon prototyping parts are much better in quality compared to injection-molded components. That's why vacuum casted models are perfect for testing and marketing purposes or to decide upon the final product.

The best silicone molding company helps to

create more innovative designs with fine details.

What are the applications of vacuum casting?

Silicone molding company produces and sells high-quality silicone prototyping parts to various industries. Such as

1)Consumer product manufacturers use vacuum casting to produce pens, sunglasses, and other sanitary products. Some cosmetic packages, hairbrushes, and combs are also made using this process.

2)Food and beverage industries also use this process to make food packages, bottles, food containers, cans, mugs, cutleries, and glasses.

3)Electronic industry uses silicone prototyping parts to make different electronic devices and their outer parts.

Which silicone molding company should you choose?

X Rapid Technologies has the best silicone prototyping technicians who carefully control the full process, from mixing, de-bubbling, stirring, preheating, injection to the solidification of the PU resin and rubber. That's why we are the best silicone molding company that guarantees minimal shrinkage and fine details.

Based on the silicone mold made from a product prototype, vacuum casting produces the same parts in the vacuum environment using materials similar to ABS, PU, transparent PU, and so on. The parts possess exactly the same strength and hardness as mass production products, even with the colors as required.

Our silicone prototyping technicians carefully control all operational parameters: from mixing, de-bubbling, stirring, preheating, injection, to the solidification of the PU resin and rubber, thus guaranteeing minimal shrinkage and fine details. At X Rapid Technologies, silicone prototyping parts made by vacuum casting show accurate part replication and consistent mechanical properties.

What is SLA Printing?

SLA printing service or stereolithography printing is a part of the active manufacturing technologies popularly known as vat photopolymerization or Resin 3D Printing. The printing machines are built around a similar principle that involves using a source of light like a projector or laser to cure and mold the liquid resin to give the shape of hardened plastic. The only difference between SLA printing technology and the others depends entirely on how the core components are arranged, like the build platform, the source of light, and the resin stored tank.

How does the CNC prototype work?

CNC machines are referred to as electro-mechanical devices that manipulate tools all over a changing number of axes having high precision. At the same time, it follows instructions from the computer program. The way of transforming a stock piece of material into a CNC prototype or CNC plastic prototype  is referred to as machining. Computer software like CAD and CAM are used by engineers for building models using models that are design-based like Solidworks and Fusion 360 degree. A digital model is built with the help of software that is converted into G-Code and is sent to the CNC machine for the production of a CNC machining prototype.

What is Custom CNC Machining Service?

Custom CNC Machining Service entails making parts for a specific purpose or to a customer\\'s specifications. It uses both manual and advanced machining equipment to create high-quality parts.

What is sheet metal rapid prototyping?

Sheet metal Rapid prototyping is the process of forming metals and turning them into desired shape or structure using different techniques such as assembling, folding, punching, bending, and cutting. It is a widely used method in industrial design prototyping.

Why create a plastic prototype?

While engineering prototype, manufacturers give special attention to the designs, purpose of the product, and complex drawings so that the feasibility prototype can reflect the actual product and you can do the necessary changes if there are any. A plastic prototype allows you to test the design and functionality of the actual product, and by engineering prototype, you will be able to be sure about the model, structure and features of the product before investing in the manufacturing tools. In short, a feasibility prototype is a sample of your actual product that you can modify. You can modify your plastic prototype as you need before mass production of the product. Because if anyhow, you need to do any changes in the product after producing that in a mass quantity, it will cost you millions of bucks. A plastic prototype makes sure that your product matches your expectations and you can release a product that you have thought about. 

What is a CNC machining prototype?

CNC machining prototype is a process that is operated with the help of a computer as pre numerical data has been put in the machine. CNC machining prototype is very flexible and diverse, and it is known to be one of the best CNC systems methods to craft prototypes. CNC rapid prototypes are a must for verifying the R&D work.
