General
This was a new product development project for an existing customer in Israel. The same customer had previously ordered ABS injection-molded trays and PVC extrusion profiles from us.
For this project, we developed a new mould and produced LLDPE rotational moulded water tanks for an industrial storage application.
For OEM projects involving rotational moulded products together with injection-molded parts, PVC profiles, rubber components, metal fittings, fasteners, or assembled industrial systems, explore our broader custom industrial parts manufacturing capabilities.
Custom Rotational Moulded Water Tanks
This project involves the manufacturing of custom rotational moulded plastic water tanks supplied to a client in Israel. Rotational moulding is a widely used process for producing durable hollow plastic products such as tanks and containers.
During the rotational moulding process, plastic material is heated and rotated inside a mould to form a uniform wall thickness and seamless structure. This process allows the production of strong, corrosion-resistant tanks suitable for industrial and storage applications.
Rotational moulded water tanks are commonly used in industrial systems, water storage, and equipment installations where durability and chemical resistance are required.
Yutung Industrial provides customized plastic manufacturing solutions including rotational moulding and injection moulding based on client drawings and project requirements.
Picture
Quantity
After the new mould was completed, two samples were produced for customer evaluation and approval.
The confirmed batch quantity was 400 pieces. Due to the urgent delivery schedule, 50 tanks were shipped by air, while the remaining 350 pieces were arranged for ocean transportation.
Material
The tanks were manufactured from LLDPE, or linear low-density polyethylene, according to the customer’s confirmed material and application requirements.
The selected grade, color, wall requirements, and moulding parameters were reviewed before sample and batch production.
Surface
The tank surface was produced with a fine sand-textured finish according to the approved sample and appearance requirements.
Process
The water tanks were manufactured by rotational moulding, also known as rotomoulding. This process is suitable for producing hollow plastic components with enclosed shapes, seamless structures, and relatively consistent wall distribution.
The production scope included mould development, sample production, rotational moulding, surface finishing, inspection, and batch manufacturing according to the customer’s approved design.
During rotational moulding, plastic material is heated while the mould rotates around multiple axes, allowing the material to coat the internal mould surface and form a hollow, seamless component.
The process is commonly used for tanks, containers, housings, and other large hollow plastic components requiring one-piece construction.
To compare rotational moulding with plastic injection moulding, extrusion, compression moulding, casting, machining, and other production methods, explore our complete custom manufacturing processes.
