A decking board is primarily made by Plastic Extrusion. Plastic extrusion melts polymer and pushes it through a die into a continuous profile, pipe, tube, sheet or film that is cooled and cut to length. Below is the full route to make a decking board, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a decking board is made
The usual route, raw material to finished part. The amber step is where the decking board gets its basic shape.
Material
Select the polymer grade and colourant for the decking board and dry the pellets.
Plastic Extrusion
Melt the plastic and push it through the die as a continuous profile to make the decking board.
Tooling Low to medium Tolerance ±0.1 to 0.5mm Lead 3 to 8 weeks
Trim
Cool, pull and cut the profile to length.
Secondary
Where the decking board needs them, add inserts, printed graphics or machined details.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Assembly
Where the decking board joins other parts, snap-fit, weld or bond it into the finished product.
Tooling Low Tolerance good Lead immediate
Inspection
Check fit, finish and any functional dimensions.

Cost
What a decking board should cost
Pipe, profile, sheet of constant section; cheap die, priced by weight/length. High-volume continuous.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a decking board at your volume, in your currency, are in the dossier.
