Batch production is a method whereby the components of an item are produced in separate stages on separate machines to create different batches of products. Using CNC machines for batch production can streamline the workflow because of the reliability, accuracy, and speed of CNC-based manufacturing.
A computer numerical control (CNC) router is a computer-controlled cutting machine related to the hand-held router used for cutting various hard materials, such as wood, composites, aluminium, steel, plastics, glass, and foams. Automation and precision are the key benefits of CNC router tables.
There are basically five different types of CNC machines:
- CNC Plasma Cutting Machine.
- CNC Laser Cutting Machine.
- CNC Milling Machine.
- CNC Router Machine.
- CNC Lathe Machine.
Injection molding is a manufacturing process in which parts are produced by injecting material in liquid form into a mold. It is most commonly performed with thermoplastic polymers, but can be used with a variety of other materials to include metals and glass.
Injection molding machines are able to process two or more different plastics at the same time. The initial creation of a mold can be expensive. For this reason, large production runs using plastic machining can cost up to 25 times more than plastic injection molding.
The pressure on the face of the injection screw or ram when injecting material into the mold, usually expressed in PSI.
There are two primary types of plastics: thermosets and thermoplastics. The main difference between these two types of plastics is that thermosets permanently cure.
A wide variety of finishes are available for vacuum castings. Pigments/tints in the resins, bead blast, painting, surface textures, vacuum metalising, electroplating.
Short batch production, or when both aesthetics and functionality are required. Clear parts and also rubbers of varying Shore A harnesses can be produced using this process. There is no need for hard tooling with this process, so huge cost savings can be achieved if the quantities are suitable.
There are three main types of lasers used in laser cutting. The CO2 laser is suited for cutting, boring, and engraving. The neodymium (ND) and neodymium yttrium-aluminum-garnet (ND-YAG) lasers are identical in style and differ only in application. ND is used for boring and where high energy but low repetition are required. The ND-YAG laser is used where very high power is needed and for boring and engraving. Both CO2 and ND/ ND-YAG lasers can be used for welding.
