Plunger Lubricants
The use of a small amount produces high performance and factory environment improvement
In die casting, plunger lubricant is essential for the lubrication of the sleeves and tips that are used to force the molten metal material into the molds.
The "NEOCASTER" plunger lubricant is used in the forming of aluminum for items such as automobile and motorcycle parts and mobile phones.
Water-soluble white type
These are water soluble and do not contain any graphite, so there is less soiling of the machine. These can also improve the casting surface on the product.

| CF-W2 | 30 | 7.7 | 0.98 | Light yellow emulsion | A non-wax type that can reduce the soiling of the machinery. |  |
| SP-70 | 40 | 9.9 | 0.99 | White dispersing liquid | The good attachment inside the sleeve and the excellent spreading properties produce a good lubrication film. | |
| P-1200N | 600 | 9.0 | 0.99 | White dispersing liquid | The blend is one that generates little gas and a strong lubrication film is formed inside the sleeve, so it shows excellent lubricating performance and prevents erosion and wear. |
Water-soluble black type
The lubricating performance of graphite means that the lubricating performance of this type is in no way inferior to that of oil-based types.

| PW-60 | 1800 | 1.00 | Dark gray emulsion | This product shows good lubricating performance, so it has many proven results in use on medium and large-sized machines and can be used in a wide range of applications. | |
| PW-100 | 830 | 1.00 | Gray emulsion | For large-sized machines of 1,000 t or higher. This has excellent spreading and adhesion properties inside the sleeve and good lubricating performance. | |
| AQ-G | 1800 | 0.99 | Dark gray emulsion | This is a non-wax type that can reduce pipe clogging and dirt accumulation around the machinery. | |
W/O white type
This is a special lubricant type with performance that combines the "lubricating performance" merit of oil-based lubricants with the "safety, environmental performance and pin hole reduction" merits of water-soluble lubricants.

| RE-76 | 1400 | 0.96 | Milky white emulsion | This is suitable for large-sized machines. The heat resistance has been improved from RE-77 and it exhibits excellent lubricating performance. | |
| RE-77 | 720 | 0.96 | Milky white emulsion | This is suitable for small- and medium-sized machines and it can be expected that there will be an improvement of the internal quality and a reduction of soot compared with the conventional oil-based type. | |
Oil-based non-pigment type
This is a yellow oil lubricant that is highly versatile.

| P-100 | 100 | 0.90 | Light yellow liquid | Oil-based non-pigment type. This contributes to an improvement of the working environment and machine maintainability (for small- and medium-sized machines). | |
| P-400 | 400 | 0.90 | Light yellow liquid | Oil-based non-pigment type. This contributes to an improvement of the working environment and machine maintainability (for small- and medium-sized machines). | |
| P-800 | 800 | 0.90 | Light yellow liquid | Oil-based non-pigment type. This contributes to an improvement of the working environment and machine maintainability (for small- and medium-sized machines). |
Oil-based white type
This is blended with white solid lubricants. It has excellent lubricating performance that means it can even be used on large-sized die casting machines and it helps extend the service life of tips and sleeves.

| BW-150 | 3000 | 0.93 | Brown liquid | This is suitable for medium-sized machines. It also has many proven results in magnesium casting. | |
| NW-11 | 1600 | 0.94 | Brown liquid | This is a low-viscosity white oil-based type. It is effective for the beautification of the work environment and has a moderate ability to maintain an oil film on the tip. | |
| PWS-850 | 1200 | 0.98 | Light yellowish brown liquid | This is a plunger lubricant that has white solid lubricant dispersed in the oil. It has good metal surface wettability and also displays stable lubricating performance in the high temperature range. | |
| PWS-900 | 1200 | 1.00 | Light yellowish brown liquid | This has the best lubricating performance of the white oil-based types. The performance is exhibited with just a small amount applied and it can improve the environment and suppress the generation of gas. |
Oil-based black type
This is a graphite type oil-based plunger lubricant that has natural graphite blended into refined mineral oil.

Granule lubricants
These suppress the generation of fire and smoke and improve the factory environment, including as a measure to keep the area around the molten metal supply port clean.

| DL-520 | 0.60 | White granules | For medium-and large-sized machines. These suppress the generation of fire and smoke and improve the factory environment, including as a measure to keep the area around the molten metal supply port clean. | |
| MCN-20 | 0.60 | Black granules | These are applied inside the sleeve from a dedicated supply device and then the temperature in the sleeve causes them to melt and form a lubricant film. There is less scattering at the time of application than when using the conventional oil-based and water-soluble plunger lubricants, so the problem of soiling around the sleeve is solved. |
Powder lubricants
The molten metal surfacing mechanism of the insulating gas suppresses the contact between the molten metal and the sleeve, prevents the generation of a solidified layer and promotes the fluidity of the molten metal.
