World Leader in Value Adding Solutions to Die Casting Challenges
Die casting is a process in which molten metal is injected into a precisely dimensioned and reusable steel mold very quickly under high pressure. Die casting has progressed over time from its use to form relatively small parts made from zinc and other lower melting metals and alloys, to the casting of very large and often complex parts, such as engine blocks, which is done today. Currently, parts are most frequently made from relatively high melting alloys of aluminum or magnesium and are cast at very high pressures to ensure complete cavity fill and minimum porosity from entrained gases.
As die casting conditions grow more severe in temperature, pressure and increased part size, the need arises for lubricants and related ancillary products to enhance the process. For over fifty years Chem-Trend has developed innovative solutions to help Die Casters continue to advance their operational efficiency and lower their production costs, even as the industry has faced increasing challenges for more part complexity and greater throughput.
In a die casting system, unique process aid requirements arise because of the thermal stresses experienced as a result of the exposure to molten metal. These include:
- Die lubricants that are applied to the die to enable production of good castings.
- Plunger lubricants that perform at the interface of the plunger tip and shot sleeve.
- Ancillary products that facilitate the smooth operation of the die casting machine and related processes.
All materials must function under extreme pressure and molten metal exposure. At Chem-Trend, we understand the unique requirements of the die casting operation and we have developed a broad portfolio of products to address the challenges found in today’s die casting operations.
The function of a die lubricant is to facilitate production of high quality castings productively while minimizing the environmental impact in the work place and in the effluent stream. From our years of working shoulder-to-shoulder with our customers on their shop floors, we have developed an extensive knowledge of the problems you face in your die cast operations. Problems such as:
- In-Cavity Buildup/Carbon
- Cold Shut
- Fish Eye
- Environmental Challenges
We have utilized this experience to develop products and expertise that help you overcome these challenges.
In high-pressure die casting the molten metal is injected into the die cavity through a cylindrical sleeve by a piston (or plunger) that forces the molten metal through a narrow orifice at high speed and pressure. Proper lubrication of the plunger is essential to provide smooth filling of the cavity, reduce energy consumption during the shot and extend the life of the plunger tip and sleeve. Chem-Trend makes a wide range of products to protect the shot-end components and assist in the production of high quality castings, while minimizing any adverse environmental effects.
Die casting is a complex process with intricate machines and a number of processing steps. Since these can have an impact on the quality of the product and the overall productivity of the plant, Chem-Trend has developed a complete range of offerings to serve the specialized needs of many of these stages.
