Deck rails have been integral to skateboarding since the 1980s, aiding in smoother slides on various surfaces and protecting board graphics. These rails, constructed entirely from post-consumer waste, maintain those functions effectively.

Upon purchasing my mold, expect delivery within approximately 4 weeks.
If you opt for my mold design or create your own, you will receive the digital file. You then have two choices for fabrication:
- Manufacture it yourself.
- Send the file to a professional:
- A local CNC machinist.
- A nearby mold maker.

Buy or Build an Injection Machine
While an extruder may be more suitable for this product, budget constraints necessitate the use of a V3 injection machine. Feedback on making rails with an extruder is welcome.

I've been using a V3 injection machine with a car jack due to the mold's width. The rail mold requires approximately 80 grams (2.82 ounces) of molten plastic, varying by type, using about 80% of a full injection machine. I preheat the mold for 15 minutes at 250°F (121°C) to enhance melt flow.

Instructions for Attaching Rails to a Skateboard
To attach the rails to the bottom of a skateboard, order screws compatible with both the rails and decks.
Recommended Screw Options:
- Order from this link: McMaster-Carr
- If McMaster-Carr is unavailable, use screws that match the provided [image].
For assembly, it is advisable to use a manual Phillips head screwdriver to prevent stripping the wood, though a cautious approach with an electric drill is also feasible.
