What are the specific processes for vacuum casting?

Vacuum casting is similar to injection molding in that it requires a tool with a cavity with the final shape of the component. The main difference lies in the use of "soft" molds made of silicone for vacuum casting, while "hard" metal molds processed by CNC are used for injection molding. Therefore, the disadvantage of vacuum casting is that the mold wears out faster. However, for small batch prototype plastic components that require production grade...

The difference between vacuum casting and Reaction Injection Moulding for prototyping method

Vacuum casting and Reaction Injection Moulding are common methods for hand board processing, and their principles may appear similar on the surface. The original can be made through CNC machining or 3D printing. For more complex structures, the original can be made through 3D printing, and then a silicone mold can be made using the original. Then, batch replication can be carried out using this silicone mold. However, there are still some differences...

Common problem solutions for vacuum casting

 1、 Dimensional deviation and product deformationCause and solution: It is closely related to the production process of re molding, especially the temperature control of the mold. Other reasons such as the scaling ratio of the prototype and material shrinkage should also be well controlled. Products with a length exceeding 1.5 meters need to be made using reinforced molds2、 The products produced cannot be assembledCause and solution: The drawings...

Vacuum casting: a time-saving and labor-saving way to produce small batch parts

 Vacuum casting,also known as Urethane Casting or Silicon Mold, is a process carried out in a vacuum environment. It involves defoaming, stirring, preheating, and injection molding of the castable, followed by secondary solidification molding in a constant temperature box. Through this method, the produced plastic parts can achieve similar strength and hardness requirements as ABS and other raw materials.This process is mainly applied in the...

Vacuum Casting VS 3D Printing

Perhaps people may wonder: why do 3D printing products still need to be vacuum replicated after production?The current mainstream processes for 3D printing are SLA (light curing) and SLS (selective laser sintering). The surface of products produced by SLA technology is smooth and delicate, but the strength is low and the toughness is poor; The products produced by SLS technology have good performance in terms of strength and toughness, but their...

Vacuum Casting VS CNC machining

 1. Low cost and relatively short product production cycle. There is less waste, and the processing cost is much lower than CNC machining. Due to its fast speed and low cost, it effectively solves the cycle and cost of new product development for enterprises.2. Suitable for small batch product processing and production, once an original version is made, it can be copied based on the original version, while CNC machining requires machine tools...

Benefits of Urethane Casting

 SpeedThe process of urethane casting is quicker because the silicone molds utilize to manufacture parts through this process are created very rapidly, particularly contrasted with the hard tooling utilized in injection molding. For low-volume production, it is perfect, when amounts do not explain investment in tooling of the injection mold.If the strategy is to injection mold a huge amount of parts; however some are required instantly, at that...
