Die lubricants

Die lubricants

Our die lubricants are designed to improve your processes, helping you work more efficiently. They ensure excellent release and protect the die/solder with improved wetting. They aid in metal flow, rapidly cool die surfaces, and keep a consistent die temperature. This results in quicker cycle times and a longer die life.

Common Problems Solved with this Solution

1) Porosity

Die casting often faces the challenge of porosity, characterized by small pores within castings that affect their strength. Gas porosity, driven by high metal injection speeds and external factors like water, and shrinkage porosity, caused by density variations during solidification, are the main concerns.

Chem-Trend’s die lubricants address these issues by minimizing direct contributions to gas porosity, managing cooling characteristics to prevent hot spots and shrinkage pores, and reducing over-spray to enhance vent effectiveness. In summary, Chem-Trend’s die lubricants play a pivotal role in improving casting quality by effectively tackling both types of porosity.

2) Cold Shut

In metal casting, both cold shut and porosity are common challenges, but Chem-Trend has effective solutions to tackle these issues and keep your metal casting equipment in top shape. Cold shut, where two streams don’t unite, leading to a break in the casting, often results from insufficient cleaning or the end of a cast’s life cycle.

Chem-Trend’s remedies are designed to address cold shut problems and extend the lifespan of your casting equipment. Porosity, characterized by small pores in the casting, comes in two main types: gas porosity and shrinkage porosity. Gas porosity, caused by factors like high injection velocities or water on the die, can be improved with die lubricants that enhance vent effectiveness and reduce overspray. Shrinkage porosity, stemming from the lower density of metals in liquid form, benefits from die lubricants that manage cooling characteristics, control hot spots, and enhance casting quality.

Chem-Trend’s tailored die lubricants work to minimize both cold shut and porosity issues, ensuring efficient and high-quality metal castings.

3) In-Cavity Buildup

Residues adhere to the mold, resulting in a disorderly and suboptimal operational state, denoted as “In-Cavity Buildup.” This accumulation encompasses remnants of the molding material or residuals from the molding process, impeding the mold’s efficiency. The root cause stems from either an excessive application of the release agent (which prevents adhesion) or the inadequacy of the release agent for the specific task.

Enter Die Lubricants, the paragons of mold assistance. These specialized solutions systematically address the issue by ensuring an optimal balance of release agent quantity and quality. Consequently, undesired adhesion is thwarted, preserving the cleanliness of molds and ensuring their seamless functionality. It’s akin to having a superhero dedicated to molds, ensuring that every creation emerges flawlessly.

4) Soldering

Soldering, a problematic issue in die casting, arises from the undesirable sticking of molten alloy to tool steel. This is often accelerated by high temperatures, erosion, and specific die areas susceptible to this reaction. Certain alloys heighten the risk of soldering.

To combat soldering, a crucial solution is the application of a barrier coating between molten metal and tool steel. Chem-Trend’s Die Cast Laboratory experts have innovated advanced die lubricants designed to function optimally across various temperature ranges and with different alloys. Their proprietary polymers excel in high-temperature scenarios, while silicone-free alternatives cater to cooler die surfaces.

5) Fish Eyes

Porosity in coatings is like having invisible craters that disrupt the finish, similar to the visible “fish eyes” defect. This issue arises when the coating doesn’t adhere properly, leaving small gaps. The problem often stems from not removing release agents, which act like a non-stick spray, before painting or plating.

Die lubricants serve as the cleaning crew for this problem. They enhance surface tension, ensuring the coating sticks well without creating hidden gaps. Comparable to using the right soap to clean off a non-stick spray in the kitchen, die lubricants smooth out the surface, allowing for a flawless finish. Choosing the appropriate lubricant and applying it correctly is key to addressing porosity and achieving a perfect coating.
