RD Mould

What is RD Mould? – Description:

RD Mould (short for Rotational Design Mould or Rotational Development Mould, depending on the industry) typically refers to a type of rotational mould used in rotomoulding (rotational moulding) processes. It is employed to produce hollow plastic components by heating powdered resin inside a rotating mould.

Where RD Moulds Are Used:

Agriculture – water tanks, pesticide containers, drums
Industrial Storage – chemical tanks, industrial bins
Sanitary & Septic – toilet cabins, septic tanks
Household Items – dustbins, water tubs, garden planters
Children’s Toys – playhouses, rocking toys
Outdoor Products – boats, traffic barriers, fuel containers
Safety & Firefighting – cone bases, fire extinguisher cases
Office & Institutional Use – plastic furniture, waste management bins

Common Uses of RD Moulds:

Manufacturing hollow and seamless plastic components
Creating large containers with uniform wall thickness
Producing custom or niche plastic parts at low-to-medium volumes
Designing durable outdoor or water-resistant products
Efficient multi-cavity moulding with complex shapes

Importance of RD Mould in Plastic

Allows economical production of large, hollow parts
Ensures product strength without joints or welds
Ideal for small production runs or prototype parts
Supports uniform heating and cooling for consistent quality
Compatible with a wide variety of resins, including eco-friendly plastics
Speeds up product development and custom part creation
Enables design flexibility with complex geometries

Significance of RD Moulds in Industry:

RD Moulds play a critical role in the growth of plastic rotational moulding, especially in sectors where custom, durable, hollow plastic parts are essential. In India, particularly Gujarat and Ahmedabad, RD Mould manufacturers are helping industries scale faster with innovative mould designs and reliable production capabilities.
