Our Manufacturing Process
Material Cutting
Raw polyester, polycarbonate and adhesive sheets are cut to the required size, ready for printing.
Screen Exposing
Artwork is transferred onto screens through exposure, creating precise stencils for every colour and layer.
Screen Printing
High-precision screen printing applies graphics, inks and conductive layers with consistent, durable results.
Digital Printing
Digital printing delivers fine detail, multi-colour graphics and quick turnaround for low-volume or custom jobs.
Embossing, Punching & Finishing
Embossing, die punching, lamination, laser cutting, pick & place and oven baking shape the part and build the functional layers.
Final Assembly & Inspection
Each unit is assembled and inspected before dispatch to make sure it meets specifications.
