secondary operations
Post-processing for moulded parts
Technical characteristics cannot always be achieved during moulding and often require additional operations. Some of our secondary operations include:
Assembly
We provide in-house parts assembly alongside our injection moulding, delivering finished, ready-to-use products. From simple fits to complex assemblies, we ensure consistent quality, reduced lead times, and lower overall costs.
Turning
We can turn your products to achieve precise cylindrical features, such as threads, grooves, or smooth finishes on round components. It’s typically applied when tight tolerances or fine surface finishes are required that can’t be achieved through moulding alone. This process ensures accuracy and consistency, especially for parts that need to interface with other mechanical components.
CNC Operations
NC (Numerical Control) milling is used as a secondary operation in injection moulded products to achieve high-precision modifications and complex geometries with excellent repeatability. Controlled by programmed instructions, NC milling allows for consistent, accurate machining of features like slots, contours, or holes that require tighter tolerances than moulding alone can provide. It's especially valuable for refining parts or adding intricate details in a cost-effective and scalable way.
Printing
Printing is often applied as a secondary operation to add logos, instructions, part numbers, or decorative details to injection moulded parts. It provides a professional finish and can be customized to meet branding or functional requirements, enhancing both appearance and usability.
Heat staking & setting
Heat staking is used to join plastic parts to other materials, such as metal inserts, by using heat to soften the plastic and form a secure mechanical bond. It’s commonly used for embedding threaded inserts or creating permanent, tamper-resistant joints.
Heat setting is a process used to embed components—like metal inserts—into moulded parts by heating the insert and allowing it to be pressed into the plastic. As the material cools, it solidifies around the insert, creating a strong, durable hold that’s ideal for threaded or load-bearing connections.

Exemplar piece
This in an example of a component produced using multiple manufacturing processes, starting with injection moulding to create the base substrate. The part is then overmoulded with a secondary material to add functional features such as grip or sealing. After moulding, selected areas are precision milled to achieve tight tolerances or specific surface features. The component is then finished with a soft-touch spray coating to improve feel and user interaction, while the upper section is painted with a high-gloss finish for visual contrast. Finally, pad printing is applied to add logos, symbols, or product information, resulting in a high-quality, fully finished part ready for use.
