Marine world injection moulds
Marine world injection moulds
Set of 6 stainless‑steel moulds for injection machines
The Marine World collection includes six stainless‑steel injection moulds inspired by ocean animals. They are ideal for producing recycled‑plastic keychains, educational items and small decorative pieces.
All moulds are made from AISI 304 stainless steel and are fully compatible with the Mediterranean Series. If you already own any mould from that series, you do not need to purchase the Top or Bottom Plate again, reducing costs.
- Each design is supplied as a Middle Plate (150 × 150 mm, 2 mm thick) that fits between the standard Top and Bottom Plates.
Moulds Included
- Dolphin Injection Mould — 150 × 150 mm, thickness 2 mm
- Shark Injection Mould — 150 × 150 mm, thickness 2 mm
- Crab Injection Mould — 150 × 150 mm, thickness 2 mm

Stainless Steel A2 (AISI 304) bolts and nuts system for quick opening and closing
Special design of the slotted screw holes for faster assembly/disassembly
Not suitable for use with the extruder.
We recommend using one or more support points under the down plate to extend the life of the mould.
🔩 Top and Down Plates (Optional)

For new customers, we offer:
Down Plate — 150 × 150 mm, 6 mm thick

Both plates include stainless‑steel screws and butterfly nuts.
Designed for high durability and full compatibility across all moulds in the series.
📏 Dimensions & Compatibility
The Mediterranean Series is designed as a modular system, allowing you to interchange components and reduce production costs.
All moulds share:
150 × 150 mm format
Universal Top and Bottom Plates
Optional Standard Inlet (8 mm) or Conic Drill Inlet
🧪 Approximate Plastic Amount
We provide an estimated amount of plastic (in grams) required to fill each mould, depending on the density of the material used.
Example: PP (Polypropylene) density ranges from 1.3 to 1.58 g/cm³, which affects the total amount needed.
Note: Estimates do not include the material inside the nozzle. PVC is excluded due to health and environmental risks.
🛠️ Tips
Plastic Inlet
Precious Plastic Capi Spain, recommends the Conic Drill plastic inlet option.
According to feedback from our clients and friends, using threaded inlets requires more time and effort. The plastic that remains in the threads cools down and solidifies, making it very difficult to remove before the next molding operation.
Support Points
Precious Plastic Capi Spain recommends the use of several support points under the Down Plate.
It will extend the life of your moulds. The force exerted on the Down Plate by the pressure of the plastic will be distributed among the support points.
