Custom rotomolding is a versatile manufacturing process that enables the production of large, hollow, and complex-shaped parts. This process involves loading a plastic resin into a mold cavity which is rotated on two axes. As the plastic melts and fuses, it evenly coats the mold cavity, creating a part with uniform thickness and in some cases intricate details. In this article, we will discuss the key aspects of custom rotomolding, including its cost, mold production, and design guidelines.
Custom rotomolding is a process used to produce both small and large hollow plastic products with complex geometry. The manufacturing process begins with a 2D drawing or 3D model which is used to design and manufacture an aluminum mold. The mold is then mounted on a machine and rotated on 2 perpendicular axes. The molding stage of the process can be broken down into 3 phases; heating, cooling and demolding. Once the part is demolded it then goes through a secondary trimming process which is either manual or automated. Custom rotomolding can produce a wide range of products, including water tanks, battery boxes, and other industrial components.
How Much Does it Cost to Rotomold a Product?
The cost of custom rotomolding can vary depending on several factors, including the size and complexity of the part, the material used, and the type of tooling used. As one of the best roto molding companies in the USA, Roto Dynamics offers competitive pricing and can provide a custom tailored solution based on your specific project requirements.
How Much Does a Mold Cost in Rotational Molding?
The cost of a mold in rotational molding can also vary depending on several factors. The size, complexity and type of aluminum mold. Generally speaking the more pieces a mold has the more complexity there is and the higher the cost. CNC machined molds also tend to cost more than cast aluminum or fabricated molds. For a 6” cube you could expect to pay $4000 for a mold and $15 for a part. Whether you choose a CNC or fabricated aluminum mold, Roto Dynamics can provide a customized solution based on your specific mold requirements.
How Do You Make a Rotational Molding Tool?
The process of making a rotational molding tool involves several steps, 3D part modeling, mold design and mold fabrication. Part design involves creating a detailed 3D model of the desired part or product that is then used to design the mold. The mold can be CNC machined, Cast from Aluminum or Fabricated. It is then framed and textured to provide the proper machine mounting solution and surface appearance.
How Do You Make a Rotationally Molded Part?
In order to make a rotationally molded part, you need to take the following steps. One, create a 3D drawing of the part you want to manufacture. Two produce a mold cavity which can be used to on a rotational molding machine. Three, run a part on a rotational molding machine. Four, complete any secondary operations or assembly that the part requires.
What Are the Design Guidelines for Rotational Molding?
When designing a part for rotational molding, it is essential to consider several factors, including draft angles, wall thickness, and surface finish. Draft angles are used to enable the part to be easily removed from the mold, while wall thickness ensures that the part is structurally sound. Surface finish can be adjusted depending on the desired final product appearance. Roto molded water tanks and oil tanks are two common applications of rotational molding, providing durable and cost-effective solutions for various industries.
