Finishing & Assembly of Plastic Parts

A plastic part is often not finished after injection moulding. Depending on the application, parts may need to be assembled, joined with other components, inspected, labelled or packaged. Silac handles these steps in-house, reducing interfaces and simplifying coordination between production, assembly, packaging and logistics. The result is finished parts, assemblies or packaging units ready for further processing or direct shipment.

Silac offers a range of processes for the further processing of plastic parts and assemblies. These include automated assembly, manual operations and project-specific solutions for both small and large production runs.

Where additional surface treatments are required, Silac works with selected partners. These services include painting, metallisation and electroplating of plastic components.

Silac joins plastic parts with other plastic or metal components to create assemblies that can be processed further, stored or shipped directly.

Plastic parts can be individually packaged, labelled or prepared for sale. This is particularly suitable for products that need to reach the customer clean, sorted and ready for use.

Plastic parts can be permanently joined using ultrasonic welding or adhesive bonding. The appropriate method depends on the material, function and mechanical requirements of the product.

Silac prints, marks and decorates plastic parts in-house using processes tailored to the material and specific requirements. Depending on the application, these include pad printing, screen printing, digital printing, hot foil stamping and laser marking.

These printing services are also available for externally supplied parts, regardless of whether the customer has an injection moulding order with Silac.
