Slurry Mixer & Slurry Pot System: The Backbone of Investment Casting Quality

At Laxminarayan Tech., improving your investment castings begins with you-consistently preparing slurries to precise specifications. Therefore, Slurry Mixers & Slurry Pot Systems provide consistency in the construction of shells as well as the quality of the resulting castings. Lastly, Laxminarayan Technologies has designed these systems serviceable to all global foundries since its inception; therefore eliminating or effectively reducing variability and waste; enabling all manufacturers of investment castings to produce consistent high integrity product on a consistent basis.

Why Slurry Consistency Defines Casting Success

Nevertheless, the first line of defence in investment casting is the ceramic shell; any variety in the viscosity, density, and/or management of the slurry could cause: cracks in the shell, you can cause penetration into the shell from the molten metal and/or create defects on the surface of the part being produced from that shell. Based on this need, our slurry management solutions are designed to produce perfect suspension of the refractory particles, so each wax cluster is uniformly coated without flaws.

Engineered for Performance: The Laxminarayan Advantage

The Slurry Pots manufactured by IC-Machines provide high-quality construction for today’s modern foundry processes by utilizing high-quality materials and effective designs that can withstand the rigors of daily operations.

Our Slurry Pots are constructed using stainless steel 304 drum that rotates and are made with an easy to clean and replaceable polypropylene lining that provides extended life.

In addition, each slurry pot has continuous agitation through a U-shaped repair baffle that prevents the refractory material from settling within the pot. Each slurry pot contains an AC reduction gear motor driven by a belt drive which allows for smoother and more precise adjustments to the RPMs while operating the slurry pot.

The base frame for each slurry pot is built of heavy gauge steel with vibration-less bearing assemblies and has a powder coated safety cover to protect the operator from injury while operating the slurry pot.

Our slurry pot diameters range from 600mm to 1800mm so they can easily be converted from a prototype shop to an aerospace high volume production line without having to change the slurry pot hardware.

How Our System Solves Real Foundry Challenges

Challenge: Refractory Settling & Viscosity Drift However,

Our Solution: In order to uniformly suspend solids, low shear hydraulic agitation is utilized. In addition, combined with routine viscosity tests using flow cups, operators can ensure tight process control without the use of guesswork.

Challenge: Downtime for Cleaning And Maintenance

Our Solution: Removable polypropylene lining allows for quick and chemical-resistant cleaning. This reduces downtime, increases uptime, and increases production throughput.

Challenge: Energy And Labor Costs

Our Solution: Motor efficiency is optimized, while automated stirring protocols deliver up to 50% savings in power cost associated with shell-building processes. Lastly, a durable, low-maintenance design decreases labor costs by approximately 40%.

Trusted by Foundries Worldwide

Laxminarayan Technologies partners with foundries all over the world, including aerospace turbine companies in Israel and precision parts manufacturers in Afghanistan. Due to our slurry systems being manufactured with ISO 9001 certification, our customers know they are receiving reliable and high performance solutions backed by on-site technical training from our qualified engineers

Integrating Slurry Systems Into Your Workflow

To that end, when using a well-designed slurry pot, they must work together (not separately). In addition, ic-machines.com provides a comprehensive set of solutions:

• Secondary Slurry Mixers for the primary / secondary coat application process;

• Slurry Transfer Pumps that provide a means to transfer materials without interruption;

• Rain or Fluidised Bed Stucco Applicators for the next stages of shell building;

• Turnkey project support from plant design through on-site training.

Starting with the manufacturing of your slurry system to the commissioning and operation, this holistic solution is designed to allow for seamless integration of your slurry system with your Wax Injection, Dewaxing and Firing Processes so that you have an efficient production line.

Best Practices for Better Slurry Management

However, no matter how reliable the machinery is, it must be used properly. For this, the following recommended practices are useful:

• Check the viscosity of a product at each shift change and whenever new material is added

• Maintain temperatures of the slurry within their designated ranges

• Quarterly inspection of the polypropylene linings for wear;

• Documenting all adjustments, both for tracking and for improvement purposes; By creating a new routine with these simple practices combined with Laxminarayan Technologies durable hardware, you will have built a basis for producing zero defect shell packs.

Conclusion: Quality Starts with the Right Foundation

You can't substitute good metal in place of weak shell in investment casting. That's where the Slurry Mixer & Slurry Pot System is born, and this is where Laxminarayan Technologies provides unequalled value. Laxminarayan has over 40 years of R & D Experience, coupled with installations around the world and an emphasis on energy efficiency and low maintenance, which supports the foundries that we serve to be confident in their casting processes.  So, take the time to review all of our investment casting equipment at ic-machines.com or contact our engineering staff for assistance in creating a custom slurry solution and help achieve your production objectives. When your slurries are just right, your castings will speak for themselves.

FAQs

What sizes of slurry pots are available from Laxminarayan Technologies?

We can manufacture a slurry pot in 600mm, 750mm, 1000mm, 1200mm, 1500mm, and 1800mm diameter, and we can also manufacture custom configurations for your specific needs.

2. How does having the removable Polypropylene lining help with maintenance?

The Polypropylene lining is resistant to chemical attack and makes it easier to clean out the pot to maintain its life. In addition, it helps extend the useful life of the pot reducing cost of ownership over the long term.

3. Are your systems compatible with automated shell lines?

Yes! We design our slurry pots to interface with rainfall stucco coater, transfer pumps, and PLC controlled shell-building systems for complete automation.

4. After your systems are installed, do you provide
