What Is a Blow Moulding Machine?
Molded into solid objects and liquids can be used in plastic resins is a kind of modern science, which is commonly used implementation of theblow moulding machine.The machines come in various sizes, with the size of the machine determined by the desired dimensions of the finished product. Invented in 1872, the blow moulding process revolutionized the plastics industry. It is currently a multi-billion dollar business that produces about 32% by weight of all the world's plastics. Its popularity is credited to the blow moulding process, and the blow moulding machines that make millions of consumer products and blow moulding machinery parts and components that are affordable, yet strong and long-lasting.
Blow molding machine of the construction and operation is very simple. The machine is composed by the six basic components. The major components of the machine include a hopper where the raw materials are inserted, a barrel to carry the materials to the heating unit, a heater to break down the materials into liquid, a nozzle to pump the liquid into the mold, a clamping unit to solidify the shape, and an ejector to expel the finished product.
To produce an blow molded product, liquid resin is poured into the blow mold machine hopper, followed by dyes or tints. Gravity draws the resin into the barrel, and the heating process melts the resin into a smooth liquid. An blow mechanism, usually a reciprocating screw or ram injector, forces the liquid into the mold. If small amounts of the resin are desired in the mold, the reciprocating screw is used as it can inject as little as 5% of the entire amount in the hopper. The ram injector is used when at least 20% of the total amount in the hopper needs to be forced into the mold.
Mold determines the shape of the final product, the cooling liquid into a solid. While the cooling is in process, the plates of the mold are held together by either mechanical or hydraulic force. This clamping procedure determines the final shape of the finished product. Since different resins have different shrinking values, molds are designed with specific resins in mind.
Problems with blow moulding machine performance are normally uncomplicated and easily solved. Burned or singed parts can be avoided by lowering the hopper temperature or reducing processing time. Solution by adjusting the die warpage is usually the surface temperature or adjust the thickness of the mold. Surface defects in products, can be corrected by adjusting the mold temperature, humidity or pressure.
