When you are making your own parts for motors and other machinery, you may have come across the words D Sol Injection and D Stroke. Perhaps you didn't understand what these two terms mean, and you thought that it meant interchangeable parts. Many do not realize the difference in the construction of these parts. Some are made from a single solid piece of steel, and others are made of several pieces of steel all welded together. It is a bit confusing, but if you learn more about injection systems, you will find it easier to understand the difference.
Solids held together using force are called solids. When a force is applied to a solid, the atoms and molecules separate and the solid becomes one of many gases. Injection systems provide controlled, uniform distribution of gas into the workpiece. This process occurs because the parts are pressurized. Pressurized means gas is forced into a small opening.
How does D Solving work?
The process begins by directing a stream of pressurized gas (usually nitrogen) into a die. The design of this die will depend on what the part is to be made of. The part to be manufactured can be alloyed or forged. The die will allow the metal to be positioned inside the confines of the die.
A tool then cuts the desired metal piece to the precise size and shape, and the area where the part fits is sealed off. With this method, the pressure is evenly distributed over the entire part. This is done so that there is a low-pressure zone near the edges of the part, and a high-pressure zone near the center. The high-pressure zone helps to draw in the gas with low pressure and allows the metal to be drawn into the injector. The injector is tube-shaped like a large needle, and it is located directly beneath the part.
Solids are injected into the injector by the use of a large syringe. The solids allow the injector to push the gas through the injection path. When complete, the tube emerges from the other end as a flexible rubber hose. This hose is used to discharge the metal into the parts that need it. As the solids cool, they harden and form into the final shape that was desired.
How is the D Sol Injection method used in production parts?
Many injection mold manufacturers have begun using this type of molding for high-volume production parts. Because of the pressure used during this process, some manufacturers have found that parts can be processed faster than with other types of manufacturing methods. Because of the high-quality parts that can be created with this injection method, it has become one of the preferred manufacturing processes for many different industries.
How are parts formed under the D Solver concept?
Through the use of a computer program that controls the machine...the parts are formed under a great deal of pressure. When the parts cool, they form in exactly the way that the user wants them to, creating a professional-looking part with a perfect finish.
Why is D Sol Injection better than other types of injection molding?
D Sol Injection requires lower overall pressures than other manufacturing processes. Because of the pressure used, the parts form faster than other methods. By using lower overall pressure, this type of operation is also quieter.
How are the parts formed under the pressure?
After the material is heated, it is injected into the cavities of the mold. The cavities are designed to create metal grains as the liquid metal passes through. In order to keep the metal from cooling too quickly after the metal is molded, the injection process is performed in a feed-forward fashion...into the metal.
What are the pros and cons of using this method of metal injection?
The pros of this process include faster production times, higher precision, and less waste. The cons of using this process are that it can be more expensive, especially when multiple parts need to be made. Another problem that can occur is if the temperature outside the mold is greater than the inside temperature of the metal being molded. This can result in the metal melting and the injection process will be stopped.
If you are interested in using D Sol Injection in your next project, you may want to contact a metalworking shop to discuss your options. There are many variables that can affect the price of the metal that you want to be molded. The materials, processes, and the type of metal being used will all have an impact on the price of your project. Before you select this method of creating parts, you should compare prices from different shops in your area to ensure you get the best deal possible.
