Manufacturing Process
From drawing to packed profile
Drawing
2D drawing, 3D file, sketch or an existing sample.
Material
PC or PMMA, single-colour or two-colour, selected for optics, impact and UV stability.
Tooling
In-house die design and die manufacturing.
Extrusion
Trial run and parameter setting on a matched extrusion line.
Cutting
Cut to length, mitring, notching, drilling and CNC machining.
Inspection
Dimensional, appearance and optical checks against the approved sample.
Packaging
Protective film, sleeving, cartons and pallets to your requirement.
Quality Control
How the profile is checked
- Incoming resin inspection and batch traceability
- First-piece approval against the approved sample or drawing
- In-process dimensional checks on profile width, height and wall thickness
- Light transmission and haze measurement on optical grades
- Appearance inspection under standard lighting conditions
- Final random inspection before packing and palletising
