What is the injection molding machine?

shaping of liquid plastic resins into solid, usable objects and parts is a modern science that is commonly performed using a injection molding machine. Machines come in different sizes with the size of the machine designed by the required dimensions of the finished product. Invented in 1872, the Injection process was revolutionized by the plastic industry. Currently, it is more billions of dollars, which produces about 32% of the weight of all world plastics. Its popularity is attributed to the injection and machine process that creates millions of consumer products and production parts and components that are affordable, yet strong and long -term. The machine consists of six basic parts. The main components of the machine include hoppers where raw materials, barrels that transmo materials to the heating unit, heating for liquid materials, a pumping nozzle, a clamping unit for reinforcement and ejector to exclude the finished product.

To create an injected product, liquid resin is poured into the injection molding machine, followed by dyes or shades. Gravity attracts resin to the barrel and the heating process melts the resin into a smooth liquid. The injection mechanism, usually a reciprocation screw or RAM, push the liquid into the mold. If a small amount of resin is required in the form, the reciprocal screw is used, as only 5% of the entire amount can be accumulated into the hopper. The RAM injector is used when at least 20% of the total amount in the hopper must be forced into the mold.

The

form determines the shape of the finished product and cools the liquid into the solid. While cooling is in the process, the mold plates are held by Together by mechanical or hydraulic force. This clamping procedure determines the final shape of the finished product. Because different resins have different decreasing values, forms are designed with respect to specific resinse.

Injection machine problems are usually uncomplicated and easy to solve. Burned or sung parts can be prevented by lowering the hopper temperature or shortening the processing time. Warpage is usually solved by adjusting the surface temperature of the mold or adjusting the mold thickness. Impersions on the product surface can be repaired by temperature treatment, humidity or pressure levels.
