Types of molding process:

Blow molding is a popular process for producing hollow plastic parts, such as bottles and containers. In this process, a molten tube of polyethylene 3840 is extruded and clamped between two mold halves. Compressed air is then blown into the tube, causing it to expand and conform to the shape of the mold cavity.

Injection molding is another common process used with polyethylene 3840. In this process, the resin is melted and injected into a mold cavity under high pressure. The mold is then cooled and opened, allowing the part to be ejected.

Film extrusion is a process used to produce thin, flexible sheets of polyethylene 3840. In this process, the resin is melted and extruded through a die, which shapes the material into a thin film. The film is then cooled and wound onto a roll.

Thermoforming is a process used to produce parts from flat sheets of polyethylene 3840. In this process, the sheet is heated until it becomes pliable, then formed over a mold using vacuum pressure or mechanical force.

Rotational molding is a process used to produce large, hollow parts, such as tanks and containers. In this process, a mold is filled with a measured amount of polyethylene 3840 powder. The mold is then heated and rotated, causing the powder to melt and coat the inside of the mold cavity. The mold is then cooled and opened, allowing the part to be removed.

In conclusion, there are several different types of molding processes that can be used with polyethylene 3840, including blow molding, injection molding, film extrusion, thermoforming, and rotational molding. Each process has its advantages and disadvantages, and the choice of process will depend on the specific application and requirements of the part being produced.

Rotational molding:

Rotational molding, also known as rotomolding, is a process used to produce large, hollow parts from thermoplastic materials such as polyethylene 3840. This process involves heating a mold that is filled with a measured amount of powdered resin, which is then rotated on multiple axes until the material has melted and coated the inside of the mold cavity. The mold is then cooled and opened, allowing the part to be removed.

The rotational molding process was first developed in the 1940s for producing hollow toys. Since then, it has evolved to become a popular method for producing a wide range of large, complex parts such as tanks, containers, and playground equipment. One of the advantages of rotational molding is that it can produce parts with uniform wall thickness and intricate shapes that would be difficult or impossible to achieve with other molding processes.

The rotational molding process starts with a mold that is typically made of aluminum or steel. The mold is designed to have one or more openings for filling and venting, as well as for attaching any necessary hardware or fittings. The mold is then loaded with a measured amount of powdered polyethylene 3840 resin.

The mold is then heated in an oven or furnace while it is rotated on multiple axes. The heat causes the resin to melt and coat the inside of the mold cavity, creating a uniform layer of material. The rotation helps to ensure that the material coats the entire surface of the mold, resulting in a part with consistent wall thickness.

Once the material has melted and coated the inside of the mold, it is cooled using air or water. The cooling process can take several minutes to several hours, depending on the size and complexity of the part. Once the part has cooled sufficiently, the mold is opened and the part is removed.

One of the advantages of rotational molding is that it can produce parts with complex shapes and features without the need for additional assembly or welding. This can result in parts that are stronger and more durable than those produced using other molding processes.

Additionally, rotational molding is a relatively low-pressure process, which means that it can be used with a wide range of materials, including those that are not suitable for high-pressure injection molding.

In conclusion, rotational molding is a versatile and effective method for producing large, hollow parts from thermoplastic materials such as polyethylene 3840. This process offers several advantages over other molding processes, including the ability to produce parts with complex shapes and features, and the ability to use a wide range of materials. While there are some limitations to the process, such as longer cycle times and higher tooling costs, rotational molding remains a popular choice for producing a wide range of industrial and consumer products.

First stage of rotational molding:

A hollow metal mold is filled with a predetermined and calculated amount of powder or liquid raw material, proportional to the weight of the sample. The size and amount of materials used depend on the surface area of the mold, the thickness of the piece, and the density of the plastic used. Another important advantage of rotational molding is the absence of waste in plastic materials, as all plastic used in making the product is consumed.

Second stage of rotational molding:

After the mold is closed and positioned correctly, it is rotated in two directions in a heated environment. This heating can be done by various methods such as displacement and electricity, infrared, flame, or oil.

It is important to note that the rotation speed of the mold in the rotational molding process is relatively low (usually up to 12 rotations per minute). Therefore, the process should not be confused with centrifugation, which is done at high speeds.

Although high-speed rotation of the mold in centrifugation may seem attractive at first because it increases production speed, it will create problems in creating products with complex shapes. In rotational molding, plastic is placed at the bottom of the mold and with the rotation of the heated mold, the entire surface of the mold is coated with the powder and lifts the melted plastic. By changing the speed of the perpendicular rotation axes, the thickness of the product can be controlled. Areas that require a higher thickness should be more regularly filled with powder pools.

Third stage of rotational molding for plastics:

In the third stage, the heated mold is separated from the heating elements or heating elements and the cooling cycle begins. The rotation and rotation of the mold continues in this stage. Cooling is usually done with high-speed air or sometimes with water spray to solidify and harden the sample. If too much water is used in the cooling process and this water is added too quickly to the cycle, it may cause damage, shrinkage, and product deformation.

When the material cools, it changes from a viscous and fluid state to a semi-solid state and at the end of the cooling stage, it becomes a hard solid. When the cooling is sufficient and completed, the mold can be opened.

Fourth stage of rotational molding for plastics:

The final product is removed from the cooled mold and the process is ready for producing a new product and the next cycle.

Advantages:

  • A seamless, hollow piece can be made in one piece.
  • The final product will necessarily be stress-free. (There is no waste stress in this process.)
  • Molds are relatively inexpensive.
  • Mold making time is relatively short.
  • There will be no waste material as all material is used in making the piece.
  • It is possible to make multi-layered parts.
  • Various types of parts can be produced simultaneously on one molding machine. (Multiple molds on one rotating device)
  • Inserting is relatively easy.
  • Various products can be produced in complex shapes and dimensions.
  • The wall thickness is uniform throughout all parts.
