What is the formation of the reaction?

Reaction pressing is the production process of the machine parts and product components. The process of forming the reaction varies from a normal injection molding in one important way - the material used in the forming process requires a curing phase, while the material is still in the form. The forming material used in the reaction injection molding process offers specific advantages over the materials used in normal shaping. On the other hand, injection of the reaction requires more time and expensive forming materials.

Injection is a common manufacturing process. In most cases, the liquid agent is powered to the Hlozská reservoir, where it is heated and mixed. The agent is then forced to a pre -made cavity called the mold, where it cools and harden. The mold is made using a separate machining process and is often removable, allowing one injection machine to create multiple items. The hard object is removed and placed in an area where it heals and further solidifies.

In response of injection molding machines there is another phase after it isagent injected into the machine. During this phase, the agent heals while still inside the mold. There are different ways to achieve this, but the common method is through a secondary chemical reactant that is injected together with the agent. Other methods include heat or various forms of radiation.

The curing phase separates the pressing of the reaction from the normal process and gives it a specific set of advantages and disadvantages. The biggest advantage lies in the injected agent itself. The time substances used for the reaction pressing process are thinner and have lower viscosity than the agents used in the standard process. This allows the agent to fill small spaces and thin areas.

The cure process in the form improves this basic function. When the part comes out of the machine, it is already cured and almost in the final shape. This means that small areas and thin spaces have an even less chance of breaking. As a result, the reactive process is urye when the mold contains very fine sections.

There are two main disadvantages to press the reaction; Time and money. Because the material needs to be cured in a forming machine, it means that fewer parts are produced at the moment. The standard machine can complete several forms and let them all be cured at the same time. In addition, the agents are used in the process very specialized - they are usually more expensive than the materials used in the normal forming process.
