SKATE RAILS: how 2 make / use recycled skate rails
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.

Steps
Step 1: Order / Make the Mold
You can purchase my mold or its design from my website (link below), or create your own version.
Step 2: Having the Mold Made!
Upon purchasing my mold, you can expect delivery within approximately four weeks.
If you purchase or create the mold design, you will receive a digital file. You will then need to have the mold fabricated, for which you have two options:
- Fabricate it yourself.
- Send the file to a fabricator:
- A local CNC machinist.
- The nearest available mold maker.
Step 3: Reycled Used Plastic
Collect plastic for shredding or purchase pre-shredded plastic. For durability, type #2 HDPE is recommended.
Step 4: Get Injection Machine
Purchase or Construct an Injection Machine
For detailed instructions, refer to this video guide.
If you have insights or experience in producing rails with an extruder, your feedback would be valuable.
Step 5: Plastic Education!
Learn to use your injection machine and mold with this guide (link below). For any queries, please email preciousplasticpasadena@gmail.com.
Step 6: Inject!
I've been using an injection machine with a carjack, as the mold is too wide to attach directly.
The rail mold requires approximately 80 grams (2.8 ounces) of molten plastic, depending on the plastic type. This amount uses about 80% of a fully filled injection machine.
I pre-heat the mold for 15 minutes at 250°F (121°C) to ensure optimal melt-flow when the molten plastic is injected.
Step 7: Screws!
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.
Step 8: SKATE & DESTORY
Create custom rails or other items using injection molds to your specifications.
