Gather Resources: Collect resin, latex, and silica for plastic production in Sky Factory 4
In Sky Factory 4, plastic is a versatile material essential for crafting advanced machinery, storage solutions, and decorative items. To produce plastic, you’ll need three key resources: resin, latex, and silica. Each of these materials serves a specific role in the production process, and understanding where and how to gather them efficiently is crucial for scaling your plastic production.
Resin is the backbone of plastic production, acting as the primary binding agent. It’s obtained by harvesting rubberwood logs, which can be found in the mystical grove or grown in your own tree farm. To maximize resin yield, use a treetap on rubberwood logs, ensuring you have a sustainable source by replanting saplings. A single rubberwood log yields 2-4 resin, so plan your farming layout to accommodate large-scale production. Pro tip: Automate the harvesting process with a tree farm and an automated treetap system using pipes and item conduits for seamless collection.
Latex, another critical component, is derived from the same rubberwood trees but requires a different extraction method. By processing rubberwood logs in a fluid press, you’ll obtain latex fluid, which can then be converted into latex pellets for plastic crafting. Each log produces 200-400 millibuckets of latex fluid, so pair your fluid press with a storage system like tanks or barrels to avoid overflow. For efficiency, integrate this process into your tree farm automation, ensuring a steady supply of latex without manual intervention.
Silica, the final ingredient, is sourced from sand or gravel, which are abundant in the early game but require refinement. Use a thermal centrifuge to process sand into silica dust, with a 1:1 ratio of sand to silica. Alternatively, gravel can yield silica pearls, which are more efficient but require additional processing steps. For large-scale production, set up a dedicated sand or gravel mining operation with automated sieves and centrifuges. Silica is also a byproduct of slag processing, so consider integrating slag recycling into your resource loop for added efficiency.
Balancing the collection of resin, latex, and silica is key to maintaining a steady plastic production line. While resin and latex rely on renewable rubberwood trees, silica requires non-renewable resources like sand or gravel, making it the bottleneck in long-term production. To mitigate this, invest in early-game sand or gravel collection and storage, or explore alternative silica sources like slag. By optimizing your resource gathering and automating the process, you’ll ensure a consistent supply of materials for all your plastic needs in Sky Factory 4.

Set Up Machines: Build extruders, compressors, and molds for efficient plastic crafting
To craft plastic efficiently in Sky Factory 4, setting up specialized machines is crucial. The extruder, compressor, and mold form the backbone of your plastic production line. Each machine serves a distinct purpose, and their synergy ensures a streamlined workflow. Start by constructing an extruder, which melts raw materials into a moldable state. Pair it with a compressor to apply the necessary pressure for shaping, and finish with a mold to achieve the desired plastic form. This trio of machines transforms basic resources into versatile plastic components, essential for advanced crafting.
Consider the extruder as the heart of your operation. It requires a steady supply of energy and raw materials like rubber or latex. Use a Thermal Expansion machine or similar mod-compatible device to heat and liquefy the input. Ensure the extruder is connected to a power source capable of sustaining high temperatures, such as a Steam Dynamo or Energy Cube. For optimal efficiency, automate material input using item conduits or pipes, reducing manual intervention. Remember, the extruder’s output rate depends on its power supply, so balance energy consumption with production needs.
Next, the compressor plays a pivotal role in shaping the extruded material. It applies pressure to the molten plastic, preparing it for molding. Integrate a compressor into your setup by linking it directly to the extruder’s output. Use a Pneumatic Craft compressor or similar mod-compatible machine for this task. Calibrate the pressure settings based on the plastic’s intended use—higher pressure yields denser, more durable products. Automate the process by connecting the compressor to a redstone signal or control system, ensuring seamless operation without bottlenecks.
Molds are the final piece of the puzzle, determining the plastic’s shape and functionality. Design or acquire molds tailored to your crafting goals, whether for pipes, sheets, or custom components. Place the mold adjacent to the compressor’s output, ensuring the molten plastic flows directly into it. For precision, use a Molding Press from Immersive Engineering or a similar mod to apply uniform pressure and heat. Regularly inspect molds for wear and tear, as damaged molds can produce defective items. Store extra molds in a storage system for quick swaps, maintaining production continuity.
In conclusion, building extruders, compressors, and molds in Sky Factory 4 transforms plastic crafting from a manual chore into an automated, efficient process. Each machine’s role is distinct yet interdependent, requiring careful planning and integration. By automating material flow, optimizing energy use, and maintaining equipment, you’ll establish a robust plastic production line. This setup not only saves time but also unlocks advanced crafting possibilities, making it a cornerstone of any successful Sky Factory 4 base.

Automate Processes: Use item ducts and controllers to streamline plastic production workflows
In Sky Factory 4, automating plastic production is a game-changer for efficiency, and item ducts and controllers are the backbone of this process. These tools allow you to create a seamless workflow, ensuring that raw materials are transported, processed, and stored without manual intervention. By integrating item ducts with controllers like the Item Filter and Item Router, you can dictate exactly where and when items move, preventing bottlenecks and maximizing output. For instance, routing saplings to a Planter and directing wood to a Sawmill automates the early stages of plastic production, freeing you to focus on more complex tasks.
Consider the setup: start by connecting your sapling farm to an item duct system, using an Item Filter to ensure only saplings pass through. Route these to a Planter, where they grow into wood logs. From there, another duct system transports the logs to a Sawmill, converting them into planks. The beauty of this system lies in its scalability—as your production needs grow, simply extend the duct network to include additional machines like the Compresser or Extruder. Each step is interconnected, creating a self-sustaining loop that minimizes downtime and resource wastage.
One common pitfall is overloading the system, which can lead to item loss or inefficiency. To avoid this, use Item Routers to distribute items evenly across multiple machines. For example, if you have three Sawmills, configure the Router to send wood logs to each one in a round-robin fashion. Additionally, incorporate Storage Drawers or Item Barrels at key points to buffer excess materials, ensuring the system doesn’t stall due to full inventories. This balance between production and storage is critical for maintaining a smooth workflow.
Persuasively, the investment in item ducts and controllers pays dividends in the long run.
