Mardon Cylinder Specifications Plastic Injection Machine
The Mardon cylinder is one of the plastic injection devices that plays an important role in the development of the plastic industry. Today, plastic products account for a huge part of production and are still considered as one of the most demanding needs in the market. In this regard, various devices and methods for producing plastic parts have been marketed, and the Mardon cylinder is one of these methods. The Mardon cylinder is a key element in plastic injection and extruder machines, which has a direct impact on the efficiency and quality of manufactured products. The Mardon cylinder melts the materials by using heaters and guides them forward by rotating the spiral. to enter the mold. As one of the reliable suppliers of cylinders and cylinders in Mashhad, we provide the possibility of purchasing these products with expert advice and detailed examination.
The Mardon or spiral cylinder plays an important role in the preparation of raw materials for the plastic industry for the plastic injection machine. In this method, raw materials enter the cylinder and become powder. Then, by combining and adjusting the temperature, they reach the melting point and are directed from the outlet of the cylinder to the molding machine. The structure of the Mardon cylinder is similar to a meat grinder, inside which there is a spiral tube, which stirs the ingredients uniformly. The output of this cylinder is molten plastic materials that are prepared for molding.
Cylinder and spiral are widely used tools in injection and extruder machines and can determine the quality of manufactured products. These devices were added to old devices from the 1950s to the 1960s in Europe and the United States, and they brought a significant improvement in the quality of the products. Uniform structure and uniform distribution of temperature throughout the sections are the important tasks of Mardon cylinders, which cause a uniform and clean structure in plastic products and produce quality products.
Mardon cylinder
- Designing and manufacturing all kinds of cylinders and spirals for injection, extruder, and pneumatic machines
- Designing and manufacturing specialized spirals for silicone and rubber machines
- Manufacturing extruders (Deleri) in the form of granules and Wire for pipe welding in the water and sewage industry
Spiral cylinder has an important task in the plastic parts production machine. These cylinders and spirals are parts of extruders or plastic injection machines that produce plastic parts by melting and directing polymers towards the mold. The cylinder is a chamber in which the spiral is placed and, using heat, melts and liquefies the solid polymer grains. Spiral or Mardon is a metal piece and a screw that has the task of guiding the plastic material inside the cylinder towards the mold of the extruder machine.
Various types of extruder cylinders and spirals in Iran produce plastic and rubber parts with a uniform production method. These cylinders and spirals are used to produce all kinds of pipes, sheets, granules, films, tires, hoses, cable covers, etc. with special designs for each type of material.
The extruder machine has two main areas; The first area that creates the driving force and the second area that is the process area and includes the spiral and the cylinder. A spiral is a rotating cylindrical part that may consist of one piece or several parts. The design created on the spiral creates angled channels, and the value of this angle indicates the amount of melt pump or melt transfer inward. The cylinder is also a chamber where the melt is placed between the spiral and the cylinder, and during the heating process, it withstands the high pressure caused by the compression of the melt.
Mardon extruder cylinder is a type of cylinder that is used to produce products with a specific cross-section and a continuous and cylindrical shape. This cylinder has two main types, single spiral and double spiral, and its length to diameter ratio is equal to 2/3 of injection devices. Mardon Extruder cylinder has more flexibility and tolerance to moisture. According to the type of use and product, the cylinder and spiral are made of two or more parts and have different designs for each type of polymer material. For example, the cylinder and spiral of polyethylene pipe production lines are different from the cylinder and spiral of PVC production lines.
Mardon cylinder components injection machine
The Mardon cylinder of the injection machine is made quite similar to a meat grinder. This device consists of two main parts, namely spiral cylinder and spiral, and three areas:
Nutrition Area During the cylinder:
The first half of the spiral cylinder that forms the injection device receives the raw materials, i.e. the granules. Usually, the feed enters through a cylindrical funnel at the top of the cylinder.
Transfer area during the cylinder:
In this part, which is the next 25% of the length of the Mardon cylinder of the injection machine, the materials are combined and melted.
Measurement area during the cylinder:
In this part, which includes the last 25% of the length of the cylinder, the molten plastics are directed to the exit with pressure and to the determined size.
Cylinder and Mardon:
The material of the cylinder and cylinder body is usually made of steel and can withstand temperatures up to 500 degrees Celsius. The best steel for use in cylinders and mandrels is nitrogen alloy steel that maintains its mechanical properties at high temperatures. Due to the increase in temperature in the middle part of the cylinder, steel with nitrogen alloy can be one of the best choices for cylinder and mardon production.
