Injection molding machines are machines used in the manufacturing industry to mold plastics and other materials into a specific shape. These machines work by injecting molten plastic into a mold, which is then cured and removed to create the finished part. Injection molding machines can be built in different sizes and configurations to produce a variety of parts in different sizes and shapes. The machines consist of an injection unit that injects the molten plastic into the mold and a clamping unit that holds the mold together and stabilizes it during the injection process. There are also injection molding machines with multiple injection nozzles and molds capable of producing multiple parts simultaneously. Injection molding machines are used in many industries, including automotive, medical, electronics and consumer products. The machines require special attention to safety as they operate at high temperatures and pressures. It is important that they are maintained and operated according to local safety regulations to prevent accidents or injuries.
