Plastic Injection Moulding

Custom Injection Moulding

Short and long-run injection moulding in a wide range of thermoplastics. We work from your design or collaborate from scratch.

In-House Toolroom

We manufacture, service and modify new and existing injection moulds in-house, supporting production efficiency and consistent quality.

Prototype & Short Run

Small-batch production for testing, validation, or low-volume requirements — without sacrificing precision.

Overmoulding & Insert Moulding

Combining multiple materials or embedding inserts into a single moulded component — reduced assembly, stronger parts.

Engineering Support

Design-for-manufacturability reviews, material selection and tooling coordination, supported by our in-house toolroom.

Secondary Operations

In-house assembly, ultrasonic welding, printing, and finishing to deliver components ready for use.
