Rotary Platens & Secondary Injection Unit Suppliers

Rotary platens and secondary injection units are commonly used in the plastics industry to improve the efficiency and flexibility of injection moulding processes.

Rotary platens are designed to rotate moulds between two or more injection units, allowing for faster production of multi-component parts. By rotating the mould, different areas of the part can be injected with different materials, such as hard and soft plastics, in a single moulding cycle. This reduces production time and costs, while improving product quality and consistency.

Secondary injection units are used to inject additional materials, such as over-moulding or insert moulding, onto a part that has already been moulded in a primary moulding machine. This allows for the creation of complex parts with different colours or materials in a single moulding cycle. Secondary injection units can be integrated into the primary moulding machine or used as a separate machine, depending on the needs of the manufacturing process.

Overall, the use of rotary platens and secondary injection units in plastic manufacturing processes provides greater flexibility, efficiency, and quality control, helping manufacturers to meet the demands of an ever-changing market. Their use has become increasingly important as the need for more complex and diverse plastic products continues to grow.
