The first injection molding machine was developed by John Wesley Hyatt in the late 1800s. Hyatt developed the machine to produce celluloid billiard balls, which were in high demand at the time. The machine worked by injecting a small amount of celluloid into a mold, which was then cooled and removed from the mold.
Hyatt's machine was the first of its kind and paved the way for the development of the modern injection molding industry. Today, injection molding is a widely used manufacturing process for producing a variety of plastic parts and products. Injection molding machines are used in a variety of industries, including automotive, medical, and consumer products.
The first servo injection molding machine was developed by the Japanese company Niigata Machine Techno Co., Ltd. in the 1970s. The company's MD-S series of injection molding machines were the first to use electric servo motors to drive the injection and clamping systems.
Prior to the development of servo injection molding machines, most injection molding machines used hydraulic or pneumatic systems to drive the injection and clamping systems. These machines had several disadvantages, including high energy consumption, maintenance requirements, and noise levels.
Servo injection molding machines have several advantages over hydraulic and pneumatic machines, including energy efficiency, improved accuracy and repeatability, and reduced maintenance requirements. Today, servo injection molding machines are widely used in a variety of industries, including automotive, medical, and consumer products.
