Guide: Pressurized Furnaces vs. Electromagnetic Pumps in Low-Pressure Casting Systems
Read our guide to learn about the differences between sealed and unsealed low-pressure casting systems – and determine whether a pressurized furnace or electromagnetic (EM) pump is right for your foundry
Compared to gravity die casting and high-pressure casting, low-pressure casting systems are capable of producing more precise, more complex parts, and typically generate less scrap. One of two systems may be used to cast metal using the low-pressure method: sealed or unsealed.
Our latest guide, Pressurized Furnaces vs. Electromagnetic Pumps in Low-Pressure Casting Systems, details the differences between and pros and cons of sealed systems – which use a pressurized furnace – and unsealed systems – which use an open furnace and electromagnetic (EM) pump.
The Difference Between Sealed & Unsealed Low-Pressure Casting Systems
Sealed and unsealed low-pressure systems are not created equally. While both are well suited to produce complex or critical parts, the degree of control they offer, overall metal quality, amount of maintenance needed, and operational costs differ.
To help foundries compare the two options, the guide outlines the differences between pressurized furnaces and EM pumps by comprehensively analyzing the following factors:
- Casting controllability
- Maintenance and labor
- Downtime
- Cost
- Temperature control
- Metal quality
How to Decide Whether an EM Pump or Pressurized Furnace is Right for Your Foundry
If your foundry is ready to adopt a low-pressure casting system but isn’t sure whether to invest in a pressurized furnace or EM pump, read the guide. In addition to offering a comprehensive overview of the two systems, it offers guidance about how to select the system that is best suited to your casting application.
Automate Casting with CMI Novacast
Since its founding in 1981, CMI Novacast has helped foundries automate their casting process with EM pumps and related systems (including heated launders, preheat ovens and control systems).
