Injection Moulding Automation

RNA Robotic Automation in Plastic Injection Moulding

Robotic Part Handling

RNA design and develop robotic systems for part handling. Robots are programmed to remove finished parts from the mould, place them in storage, or conduct post-processing tasks like trimming or assembling components.

The robots are equipped with sensors and end-of-arm tooling to handle parts of different shapes and sizes without causing damage.

Robotic Insert Moulding

In insert moulding, pre-fabricated components (inserts) are placed into the mould before plastic is injected to form a composite part. RNA integrate robotic systems into this process by using them to precisely position these inserts in the mould.

Robotic systems ensure that inserts are consistently placed in the correct position in an accurate time, improving the quality and reliability of the final product. This is particularly important in industries like automotive or electronics, where small errors in placement or changes in cycle time can lead to defective or unsafe parts.

Robotic Two Shot Moulding

Two shot overmoulding involves moulding a layer of plastic over an existing part, often made of a different material. RNA integrate robots in this complex process by handling both the initial part and the overmoulded layer, ensuring precision and alignment between the two components.

In the production of multi-material products, robotic systems can handle the transition from one moulding cycle to the next, transferring the initial component from one mould to another for the overmoulding step.

Post-Processing and Assembly

In addition to the core injection moulding process, RNA integrate robotic system in post-processing tasks, such as trimming excess plastic, finishing, and assembly of components.

After a part is ejected from the mould, robotic arms equipped with end of arm tooling can take the product to a cutting/deburring station to trim off any excess material known as “flash,” or remove a sprue ensuring the part meets the required dimensions.

RNA robotic systems are also used in the assembly process, where they can combine multiple moulded components into a final product. This is especially useful in industries that require complex, multi-part assemblies, such as automotive or consumer electronics.

RNA can take the finished products and put them through many after moulding processes such as height measurement, vison inspection, electrical testing, laser marking, etc.

The Basics of Plastic Injection Moulding

Plastic injection moulding is a manufacturing process in which molten plastic is injected into a mould, cooled, and ejected as a finished part. This process is widely used to manufacture plastic parts and components across various industries, from automotive and electronics to consumer goods and medical devices.
