What is rotational molding? Rotational Molding, also known as rotational molding or rotational injection molding, is a plastic processing technology used to manufacture hollow plastic products, such as liquid storage tanks, large containers, toys, amusement equipment, boat hulls and other large or Complex parts. Rotational molding is a very flexible process that allows parts to be manufactured in a variety of different shapes and sizes and is particularly suitable for manufacturing large parts and hollow structures. Here is the basic working principle of rotational molding: 1. Mold loading: First, plastic powder or granules are placed in the mold of the rotational molding machine. This mold usually consists of two or more parts and helps form the desired part shape. 2. Mold heating: The mold is heated, usually in a furnace or using a heating element, to cause the plastic powder to melt and adhere to the inner walls of the mold. The rotation and heating process of the mold causes the plastic to be evenly distributed within the mold. 3. Rotation: Once the plastic is evenly distributed within the mold, the mold begins to rotate, usually on a horizontal or vertical axis. This rotating process results in a uniform coating of the plastic block along the inner walls of the mold. 4. Cooling: While rotating, the mold is usually cooled, allowing the plastic block to gradually solidify and solidify. 5. Mold removal: Once the plastic has completely cooled and solidified, the mold stops rotating and can be opened to remove the finished part. Key features of rotational molding include the ability to create large, hollow, complex-shaped parts without the use of pressure or injection equipment, the ability to process a variety of different types of plastic materials, and the ability to produce hollow structures without seams or welds.

What is compression molding? Compression Molding is a plastic processing process used to manufacture plastic parts with complex geometries, often involving hard materials such as thermoset plastics and composites. The main feature of this process is that heated plastic material is placed in an open mold and then pressure is applied to allow it to fill the mold and solidify into the desired shape. Compression molding is generally suitable for low-volume production and the manufacture of parts that require high precision. The following is the basic working principle of compression molding: 1. Prepare the mold: First, you need to prepare a pair of molds, usually made of metal, to make parts of the desired shape. These molds include a fixed upper mold and a movable lower mold. The internal shape of the mold matches the shape of the desired part. 2. Melt plastic: Heat the desired plastic pellets or pellets to a molten state. Typically, this is done by placing the plastic in a mold and heating the entire mold. 3. Loading: Once the plastic reaches a sufficient molten state, the molten plastic material is placed in the lower mold. 4. Close the mold: The lower mold moves and closes, extruding the plastic into the shape of the upper mold. This can also cause too much-molten plastic to be squeezed out of the mold. 5. Apply pressure: By applying pressure, usually hydraulic pressure, the upper and lower molds are held closed, ensuring that the plastic fills the mold and fits tightly against the mold walls. 6. Cooling and solidification: Under the conditions of heating and pressure, the plastic material will cool and solidify into the desired shape. This usually takes a while to ensure the plastic is fully cured. 7. Open the mold: Once the plastic solidifies, the upper and lower molds separate, allowing the finished part to be removed. Compression molding is generally suitable for manufacturing high-quality parts such as electronic casings, electrical insulation components, engineering plastic parts, composite products, etc. Compression molding has several advantages over other plastics processing processes, including the ability to manufacture complex geometries, no need for special injection or extrusion equipment, suitability for a wide range of hard materials, and availability for low-volume production.

What is extrusion molding? Extrusion Molding is a plastic processing technology used to manufacture continuous plastic profiles, such as pipes, plates, rods, films, ropes, profiles, etc. The process involves heating, compressing and extruding plastic pellets or pellets through an extruder to form the desired cross-sectional shape, which is then cooled and solidified. Extrusion is a process that is efficient and suitable for mass production and is therefore widely used in construction, packaging, automotive, electronics, food processing and other fields. The following is the basic working principle of extrusion molding: 1. Melting plastic: First, solid plastic pellets or pellets are heated and melted, usually through a screw extruder. The screw heats the plastic to a molten state. 2. Extrusion: Once the plastic reaches a sufficiently molten state, it is pushed through a screw into a mold or extrusion head. The extrusion head usually has a specific cross-sectional shape through which the molten plastic passes to obtain the desired cross-sectional shape. 3. Cooling and solidification: Once the plastic is extruded, it is cooled through a cooling system (such as a water channel) to allow it to solidify and solidify into the desired shape. 4. Cutting and coiling: The extruded plastic profiles are cut to the required length by cutting equipment and can then be coiled, packaged or further processed into final products. Key features of extrusion include high production efficiency, the ability to create continuous profiles, lower labor costs and less material waste.

The following is the basic working principle of blow molding: 1. Melting plastic: First, solid plastic pellets or pellets are heated and melted. This is usually done in a special blow molding machine, where the molten plastic is pushed into a heated area by a screw or plunger. 2. Form the blow molding blank: Once the plastic reaches a sufficiently molten state, it is extruded or injected into the mold to form a hollow plastic blank that is similar in shape to the desired final product. 3. Blow molding: The formed blank is placed in a mold, which usually contains two halves. One mold half is held in place while the other mold half is pushed against the mold wall by injecting air or nitrogen into the blank. The blank conforms to the inner walls of the mold and takes on the desired shape. 4. Cooling and solidification: Once the plastic blank takes the desired shape, cooling air or nitrogen is used to cool the plastic and solidify it. 5. Mold separation: Once the plastic is completely cooled and solidified, the mold will separate, allowing the finished hollow plastic product to be removed. Blow molding is generally divided into two main types: 1. Extrusion blow molding: In extrusion blow molding, the molten plastic is passed through an extruder to extrude the blank and then blown into the desired shape through a mold. This method is suitable for making hollow objects such as bottles. 2. Injection blow molding: Injection blow molding combines the principles of injection molding and blow molding. First, molten plastic is injected into a mold to form a blank, which is then blown into a hollow product.
