Mould Releasing Agent
A release agent is an interface coating used on two surfaces that tend to stick to each other to make the surface easy to release, smooth and clean.
Mold release agents are used in a wide variety of molding operations including metal die casting, polyurethane foams and elastomers, glass fiber reinforced plastics, injection molded thermoplastics, vacuum foamed sheets and extruded profiles. In molding, sometimes other plastic fillers such as plasticizers will seep into the interface, and a surface remover is needed to remove it.
| Specification | Graphite I75L is a powder made on the basis of graphite and other carbon and mineral materials. |
| Application | Graphite I75L is used as an immerse product (dip-product) applied with the foundry of brass after the techniques of manual, mechanical and low pressure. Suitable for heated metal molds. |
| Treatment | ◆ Graphite I75L is mixed in distilled water or deionization water in the proportion of 1:10 and is at once ready for use. ◆ The proportion can be changed according to the weight and thickness of the sides. ◆ Heat the mold to at least 120℃ before using I75L. ◆ It is recommendable to keep the whole liquid in motion by appropriate device (stirring apparatus). |
Mould Releasing Agent I75L
Our standard mould releasing agent is named I75L. It is a powder made on the basis of graphite and other carbon and mineral materials.
I75L is used as an immerse product (dip-product) applied with the foundry of brass after the techniques of manual, mechanical and low pressure. It is also suitable for lead-free brass casting.
Benefit of using I75L
longer durability of the die, uniform surface of the castings, less subsequent after work of the casting.
Due to its layered structure, graphite exhibits excellent lubricating and parting properties which are maintained even under pressure or at high temperatures.
The single flakes are very thin and can easily position themselves between two surfaces in reciprocal motion generating a situation of three-body wear (surface-graphite-surface) with very low coefficients of friction.
This makes graphite a proven, environmentally friendly and indispensable component, for example in parting agents for metal processing or the production of high-performance lubricating grease.
Graphite is most effective for lubricants in stamping, rolling, metal, forging and general industry for processing of hot metal under pressure.
Graphite lubricant provides a lubricating layer of the following properties: resistance, minimal deposition, no biological fermentation, adhesion to the surface moisture resistance, thermal stability.
The main effect of the use of graphite in casting steel grades
(including the manufacture of seamless pipes and metal forging, stamping and rolling product):
- Reduced energy costs
- Reduction of emissions and the use of pure natural raw materials
- Savings in production costs
- Reduction of tool wear
- Improved workpiece surfaces
- Increase in productivity
- Reducing the number of defects
