The rotational molding process is a high-temperature, low-pressure plastic-forming process that uses heat and biaxial rotation to produce hollow, one-piece parts. Manufacturing large, hollow parts such as oil tanks is much easier by rotational molding than any other method. Rotational molds are significantly cheaper than other types of mold. Very little material is wasted using this process, and excess material can often be re-used, making it a very economically and environmentally viable manufacturing process.

Shanghai Sourcing provides custom plastics solutions for a variety of industries. We use the latest rotomolding technology, tooling and equipment to provide practical, innovative products for our valued customers.

Advantages:
1. Commitment to finding a workable, cost-effective solution for our customer
2. Knowledgeable design & engineering staff to help satisfy your unique requirements
3. Totally customizable solutions, including colors, graphics, inserts and mold treatments
4. Complete conception-to-delivery production capabilities
5. Lightweight, durable products that are exceptionally cost-effective in any environment
6. Strict quality control

Cost Advantage:
1. Tooling for rotational molding is less expensive when compared to injection and blow molding
2. Rotational molding lends itself to short runs of 15+ parts.
3. Existing part designs e.g. Cold Air Intake systems can be converted from a costly metal design to a cheaper high quality plastic part.
4. Recycled material can be used in some applications making the product cheaper and greener.

Time Advantage:
1. The time taken to manufacture a mold is short.
2. Short production runs can be carried out and rotationally molded part can be shipped out virtually the same day.

Design Advantage:
1. Inserts are easy to mold in.
2. Under cuts are easy to mold into a part.
3. Special Graphics can be molded in.
4. Depending on the design, the final product is relatively stress free.
Different types of resins in different colors, and glow properties.
