1. What Are the Main Reasons for the Popularity of Vacuum Casting?
The popularity of vacuum casting manufacturing technology is dependent on several factors. Similarly, vacuum casting has been used in China for a long time by Chinese manufacturers and suppliers.
One of the main reasons behind the popularity of vacuum casting at such a level is its faster production and greater work accuracy.
· Highly Précised Process
Precision is also the key factor that gives the vacuum casting technology an upper hand over the other manufacturing technologies used in China. The prototype created using vacuum casting technology does not look like a prototype. Instead, it looks like an actual product that contains a lot of details.
This capability of adding a lot of details to the prototype makes the vacuum casting technology much popular among the suppliers and manufacturers of China.
Price is something that is always considered by manufacturers before manufacturing any product. If we talk about the charges, everyone wants to get the best quality manufacturing service at the least possible price.
Here the good news is that by using vacuum casting technology, you won’t be charged much higher for manufacturing as compared to the other technologies in the market of China and the rest parts of the world. The reason for the low cost of vacuum casting technology is that this process uses silicon for the production of their molds. Most of the other manufacturing technologies use expensive metals for their manufacturing. On the other hand, if we talk about Silicon, so it is much more affordable than the other metals that are normally used.
Vacuum casting technology is considered to be this much popular by today because it allows you to use diversified types of materials in manufacturing. This kind of flexibility is a great way to manufacture the products with perfect quality using the best and high-quality materials.
Whether you use plastic as a whole in the manufacturing process or make use of some metal with plastic, you will always get the perfect prototype having a rigid shape and structure.
One of the main factors that make the people of China like vacuum casting is that this is always a speedy process. With vacuum casting technology, you can easily manufacture a large number of products in the least amount of time. Those products that require waiting for several weeks can be easily manufactured in only a few days if you use vacuum casting technology. Such faster working with greater effectiveness makes vacuum casting to be one of the highly liked technology by the manufacturers and suppliers of China.
Vacuum casting technology is useful for the manufacturing of different types of plastic products that may range from plastic bottles to packing materials. Some of the main products that are usually manufactured using this technology in China are given as under.
Generally, the food packing materials are manufactured using this technology by the manufacturers of China. The reason for using this technology for food packing is that it has higher production in speed. Therefore, proves very beneficial to produce bulk packing items easily.
There are a lot of other commercial items that are manufactured using vacuum casting technology. Among them, the products that are used highly include mobile covers, glasses, watches, and key chains, etc.
This helps the small business owners to sell these items, along with their primary business.
Generally, the products that are usually manufactured by playing with the powder are also manufactured using vacuum casting technology. Among them, some of them include detergents, soups, and cosmetics substances.
Some people call the vacuum casting technology “Urethane Casting technology.” The main reason behind this is that their mold is made from urethane material. In some cases, it is also made up of other materials, but still, most of the time, it is manufactured using Urethane, that had made people call it Urethane Casting.
The process of vacuum casting is simple, as injecting a liquefied material into the mold of a particular shape and structure. Once the liquid acquires its shape, it is then passed through other processes to create a final product or a prototype of a substance.
If we talk about plastic casting using vacuum technology, so that can be manufactured in the best way using the vacuum casting technology. The following are some of the main steps by which material passes to become a regular prototype or a final product.
The first step for the manufacturing of a product using vacuum casting technology is the creation of a model. The model is created in the 3-dimensional form of the final product that we expect from the vacuum casting machinery to manufacture. After the creation of the model, it is scanned by a high technological laser scanner so that any faults that are present in the model could be spotted and hence removed.
After the successful creation of the 3D model of the product, the next step is to create a design pattern that allows a manufacturer to prepare a mold for that particular pattern. Normally, this pattern is created using CAD software and then given a physical form to it.
This pattern is also called the master pattern, as it is considered to be the core resource for the production of the final product using vacuum casting technology.
By using the silicone and the master pattern, a rubber mold is created. The master pattern is inserted into a vacuum space around which the area is filled up with silicone. After further actions on the silicone, the mold is created. After its creation, it is kept inside an oven for about 12 hours.
After 12 hours, the mold is ready, and the manufacturer can use it to manufacture the final product.
After the mold gets successfully created, then the desired material that manufacturers want to use is injected into the mold. If a manufacturer wants to produce a plastic product, he has to insert the liquefied plastic in the mold.
Mostly, the material that is added for the manufacturing of ordinary prototypes is polyurethane resin.
When the liquid is added to the mold, the mold is inserted into the vacuum in the machinery. After further processing on the liquid inside the mold, the product becomes ready, and one can then separate the product from the mold.
5. What Can Materials Be Used In Vacuum Casting?
There are several different types of materials that you can use in vacuum casting technology for the manufacturing of your products. Choosing the right type of material in manufacturing can be highly rewarding in terms of providing you the best possible results.
Some of the most suitable materials that can be used in vacuum casting machinery include rubbers, plastic, and resins. You can also make use of other materials like glass for manufacturing your products, but that will not give you such a best result just as the above-mentioned materials.
Vacuum casting is an old manufacturing technology that doesn’t allow much diversification in selecting the best suitable material. However, if you want to manufacture small-sized products in a large quantity, then vacuum casting technology may be the perfect option for you.
6. What Are The Properties Of The Products Manufactured Using Vacuum Casting Technology?
The products that are manufactured using vacuum casting technology are rigid and flexible. According to some experienced manufacturers and suppliers of China, vacuum casting products show greater resistance to heat and fire. The following are some of the other properties of the vacuum casting products.
The products manufactured using vacuum casting technology are harder and rigid in their structure. Some manufacturer has witnessed that this technology is not much beneficial for creating a sharp design.
This is due to the reason that the sharp designs wear out during the manufacturing process due to pressure on the semi-solid material. But once the product is manufactured, it has a hard and rigid structure.
Heat resistance is something that needs greater attention during the product manufacturing process. A product that does not show much resistance to heat can easily get damaged when exposed to greater temperature.
Using vacuum casting technology, you can easily manufacture products that provide greater resistance to heat.
· Fire Resistant
Apart from being resistant to heat, the vacuum casting products are also resistant to fire. If in case these products are exposed to fire, they won’t easily catch fire. This property makes vacuum casting products to be the best ones.
