If you are looking for the most economical way to make any prototype, vacuum casting can be the best choice for you. It is known for the fast production of top-quality prototypes or end-user products. In vacuum casting, you will need the optimum temperature to cure the materials. For resin, you’ll need 30 degrees Celsius to minimize the shrinkage at 5 min vacuum pressure and a mold temperature of 60 degrees Celsius. It works just like duplication using a silicon mold. Plastic vacuum casting using silicone mold can be traced to the 1960s in German universities.
Why vacuum casting
Silicon molding results in the most amazing quality parts comparable to injection model components. It makes vacuum-casted models perfect for fit and function testing, marketing needs, or a series of final parts in limited quantities.
Where the vacuum casting can be used
Food and beverages
Vacuum casting is used in the food and beverage industry for the packaging of their final product. It is used to make plastic bottles and packaging tins.
This process is also used to manufacture commercial products that are used for protection such as mobile cases, food and drink packaging, sunglasses, etc.
Some household products are also created using the vacuum casting process. Products like detergent, food processing, and cosmetics are some examples of it.
Benefits of vacuum casting
High precision and details in the finished products
When you use silicon as a mold for your products, it ensures that the final product has the most precise details. It makes it look just like the original product. You get every detail, no matter how complex geometry the original product has.
The products which are produced using vacuum casting are of high quality. The use of resin allows you to choose the right material for making the final product. You can choose from the various level of flexibility, hardness, and rigidity of your final product. It plays a significant role in the appearance of the product.
Reduces the production cost
By using vacuum casting, your product can be much more economical. It’s because the process uses silicon to create the molds and it is an affordable material compared to aluminum and steel. So the material allows you to produce more from the mold and makes the process much more inexpensive compared to 3D printing.
Best for meeting a deadline
It is a fast method and takes very less time in creating the finished product. You can make approx 50 functioning prototype parts in 7 to 10 days. It is best when you are making a lot of products and working to meet a deadline.
Vacuum casting is much more economical as compared to 3D printing or molding injection. It allows you to produce more products without investing much. If you are curious to know more about prototyping in China, don’t hesitate to connect with our experts.
