Oct 13, 2025 by wbrum.org 20 views

Introduction

The development of a prototype is a crucial step in the product development process, and it is especially important when creating a vacuum chamber for making Mold Silicone Rubber RTV 683. A prototype is designed to enable users and makers to make the necessary changes before entering into mass production. In this context, the technology used is Lost Wax Casting, where the mold material used is Silicone Rubber RTV 683. To ensure the resulting mold is free from air cavities, an efficient degassing process is needed, which will be helped by the presence of a vacuum chamber.

The Importance of Vacuum Chamber in Degassing Process

A vacuum chamber plays a vital role in creating a vacuum condition needed in the degassing process. The vacuum chamber tube has a significant influence on the performance of this process, especially related to the volume and resistance of the tube material in holding vacuum pressure between -0.6 to -0.8 bar. In the design of a vacuum chamber tube, the material used is stainless steel 304 with a composition of 18% chromium and 8% nickel. The process of calculating the thickness of the tube is based on the pressure, volume, and permitted voltage, and the calculation shows that the nominal thickness required is 0.696 mm. However, due to difficulties in the procurement of materials with the thickness, finally, the thickness of 1 mm was chosen.

Design and Manufacture of Vacuum Chamber Tube

The design and manufacture of a vacuum chamber tube require careful consideration of several factors, including the material used, the thickness of the tube, and the volume of the chamber. The material used for the vacuum chamber tube is stainless steel 304, which is known for its high strength, corrosion resistance, and ability to withstand high temperatures. The thickness of the tube is critical in determining the performance of the vacuum chamber, and it is calculated based on the pressure, volume, and permitted voltage. In this case, the nominal thickness required is 0.696 mm, but due to difficulties in procurement, the thickness of 1 mm was chosen.

Degassing Process and Its Importance

The degassing process is a critical step in the production of Mold Silicone Rubber RTV 683, and it is essential to ensure that the resulting mold is free from air cavities. The test results show that the optimum time for the gas removal process is for 120 seconds, with a stable vacuum strength in the range of -0.6 to -0.8 bar. The volume of the mold used in this experiment is 20 cm³ with a width of 5 cm and a thickness of 2 cm. Thus, the vacuum chamber designed not only serves to minimize defects in the product but also provides efficiency in the time and production process.

Conclusion

From this whole process, it can be concluded that the development of the right vacuum chamber will have a big impact on the quality of the final product. Innovation in the design and manufacture of a vacuum chamber tube is very important to ensure the process of making Mold Silicone Rubber runs optimally. Success in designing and producing this tool will also open up opportunities for the use of Lost Wax Casting techniques in various other industrial fields, creating high-quality products that meet user standards and expectations.

Future Work

Future work in this area could involve further optimization of the vacuum chamber design, including the use of more advanced materials and manufacturing techniques. Additionally, the development of a more efficient degassing process could be explored, potentially using new technologies or techniques. Finally, the application of Lost Wax Casting techniques in various other industrial fields could be investigated, with a focus on creating high-quality products that meet user standards and expectations.
