Why Use Rotomolding to Create Plastic Lampshades?

Made of polyethylene resin as a one-piece product by rotomolding process, plastic lampshades are durable because of the watertight and airtight features, excellent impact and chemical resistant properties.

An overview of rotomolding

Rotomolding, rotational molding, or rotocasting is a manufacturing process to create hollow parts of limitless design at a relatively low production cost. A measured amount of resins are added into a mold, which is heated and rotated slowly, simultaneously, both vertically and horizontally. The simultaneous heating and rotation distributes and fuses the resin on the interior surfaces of the mold. The rotomolded product is a seamless uniform structure.

Benefits to use rotomolding to create plastic lampshades

Plastic lampshades can be made in different ways. However, rotomolding provides the following benefits.

Low tooling cost

When compared to injection and blow moulding, tooling costs are relatively low. Normally, rotomolding tooling cost is 10% to 20% of injection.

Short production lea time

Production lead time is also significantly short in comparison to other construction methods. Wall thickness can be changed easily at any stage of the process without tooling modification.This gives more flexibility to change the product over time, allowing for saving extra time and expense that other plastic manufacturing processes would normally demand.

Durability

Rotomolded plastic lamp shape is one-piece construction that is visually seamless. The material of choice for plastic lampshade manufacturing is 100% recyclable high density polyethylene. They are highly durable and ready to stand up to the elements because of the excellent features of airtight, waterproof, resistant to UV, impact and chemical resistant properties. In addition to this, the rotomolding offers the design flexibility to create complicated shape and size. The plastic lampshades are also popular to be specified for coastal and pool furniture, commercially rated for restaurant dining chair and tables, and designed as illuminated night club furniture.

Efficient light diffuser

Crafted by rotomolding process, plastic lampshades have consistent wall thickness with smooth and fine surface, making the light emit equally, softly and transparently. They are perfect for the ambiance and accent lighting for special events.
