The evolution of release agents in Masterbatch
Moldfree creates a lubricating layer between the mold and the injected part, drastically lowering the coefficient of friction.
This allows for improved ejection of parts from the mold in a clean and efficient way, without the need to use silicone or stop production to apply it manually.
Proven Results
In conducted studies, the number of ejected parts increased by 20% compared to virgin resin and silicone spray.
Key Benefits in Production
Injection Cycle Reduced
Improves the flow of the polymer, allowing injection at low temperatures. This reduces the cooling time in the mold, meaning a significant reduction in cycle time.
Antiwarping
The lubricating layer prevents stress on the piece during injection. In many cases, it drastically reduces buckling and warping of the pieces, saving material and reducing rejects.
Removes Marks from Dumpers
By migrating onto the mold surface in a microscopic layer, it prevents wear and increases durability, even on older or hard-to-polish molds. Eliminates ejector pin marks.
Perfect Finishes
Avoid flow lines, especially in pearl colors, as it creates an internal lubricating layer that results in an impeccable and homogeneous surface on the final product.
