Unleash Your Creativity with INARI
"INARI P35" is a Pneumatic injection molding machine driven by an air cylinder. The concept of making injection molding easy is the same as the manual "INARI", but we aimed to achieve more stable molding quality and support a wider range of materials.
With simple handle operation and a single switch, anyone can perform high-quality molding. With a pressure capacity of approximately 2 tons and a heating temperature of up to 320°C, it can also mold engineering plastics including polycarbonate. From prototyping in research and development, to molding tests of new materials, to small-scale production of products, it expands all possibilities of manufacturing.
Features
Easy to use and simple to operate
The operation of the "INARI P35" is extremely simple. Just insert the pellets, set the mold, tilt the handle towards you, and press the switch. No complicated operations are required, and anyone can produce stable, high-quality molding.
Large mold setting table with preheating function
Although it is a compact tabletop machine, the table has a mold installation area of 400mm x 183mm x 80mm. Large molded products can be produced, greatly expanding the range of designs. In addition, it is equipped with a mold preheating function, and detailed molding conditions can be set, allowing for high-quality molding.
We also handle a wide range of engineering plastic moldings.
The "INARI P35" has a pressure capacity of approximately 2 tons and a maximum heating temperature of 320°C. It is capable of molding engineering plastics including polycarbonate, and is compatible with manufacturing using a wide range of materials.
Simple structure that allows easy introduction of new materials
The structure is simpler than that of a typical large injection molding machine, so there is no need to worry about major problems when feeding materials. You can easily feed in a variety of materials, from materials containing fillers to waste plastics such as PET bottle caps. It is also ideal for molding tests of new materials.
Designed to enable molding with resin molds
In a typical injection molding machine, the material is injected while the cylinder is pressed against the mold. With this method, the force pushing the press shaft is transmitted directly to the mold via the cylinder, increasing the possibility of deformation or damage to the mold.
"INARI P35" inherits the structure of the conventional "INARI" series, which separates the "force to press the mold" from the "force to press the material". This unique structure realizes high pressure capacity while minimizing the burden on the mold. It is also possible to mold with resin molds made by 3D printers, making molding easier.

Specifications for each cylinder size
The heating cylinder of the "INARI P35" is replaceable and is available in three sizes: Φ10, Φ15, and Φ20. Please use the appropriate size cylinder depending on the material used and the size of the molded product.
Φ10 (Maximum extrusion amount: 8cc)
The smaller the maximum extrusion volume, the higher the pressure capacity per area. It is suitable for molding materials with extremely low fluidity, such as polycarbonate (PC).
Φ15 (Maximum extrusion amount: 20cc)
This cylinder size has a good balance of extrusion volume and pressure capacity, and is highly versatile. Although it is difficult to mold polycarbonate (PC), most other materials can be molded.
Φ20 (Maximum extrusion volume: 35cc)
The larger the maximum extrusion volume, the lower the pressure capacity per unit area. It is suitable for making large molded products using highly fluid materials such as polypropylene (PP), polyethylene (PE), and elastomers (TPE).

Molding using a mold with a sprue bush attached
1. Connecting the air compressor
Connect the "INARI P35" to the air compressor with an air hose. After connecting, turn on the air compressor and fill the tank with air. Once filled with air, open the valve of the air compressor to send air into the "INARI P35".
Precautions when using an air compressor
Please use an air compressor with a maximum pressure of 1.0MPa. The INARI P35 operates within a pressure range of 0.2MPa to 1.0MPa, but for safety reasons we recommend using it within a range of 0.2MPa to 0.6MPa.
2. Heating the cylinder and table
Plug the "INARI P35" into an outlet and turn it on. Set the target temperatures for the cylinder and table, then start heating. The cylinder temperature controller is on the right and the table temperature controller is on the left.
3. Filling with pellets
Pull out the pellet supply port and insert the pellets.
4. Adjusting the injection pressure
The injection pressure is adjusted according to the size of the molded product, the shape of the mold, and the material used.
5. Place the mold on the table
When the cylinder temperature reaches the set temperature and the material comes out of the nozzle, molding is complete. Remove the molten material and place the mold on the table so that the injection port is directly under the nozzle.
How to adjust the table height
The height of the table can be raised or lowered by turning the adjustment screw under the table. Adjust the height so that the nozzle and the injection port of the mold are in close contact when the handle is pulled toward you.
6. Injection
Pull the handle towards you and press the left and right switches at the same time to inject the material. The resin is forced into the mold, and when the injection operation stops, keep pressing the switch for a few seconds to hold the pressure. After a few seconds, release the switch, return the handle to its original position, and then remove the mold.
7. Completion
Remove the molded product from the mold and it's complete.
