Engineering & Casting Design Services

Seneca Foundry embraces modern advancements in technology and combines them with time-tested methods to improve our iron casting methods. We use 3D scanning machines, and SolidWorks 3D modeling software. These modern leaps forward in technology assist us in maintaining strict quality control for our customers while improving the efficiency of our production. The results of using this technology are faster completion times, a better product, and reduced costs to our customers.

Working Together, Partnership Approach

Low volume runs, rapid prototyping, custom cast iron, reliable delivery, our partnership approach, and being flexible to the customers' needs are what make Seneca the best Iowa foundry. We strive to work with customers early on in their casting design process so that we can deliver quality castings at a competitive price.

We understand the need for and work with customers to help reduce their costs of receiving, inspection, and handling. We do this by meeting specifications on packaging, boxes/containers, lot quantities, and just-in-time deliveries. We can handle your complete casting job from start to finish.

Converting Weldments to Castings

When considering manufacturing components, many businesses choose weldments. However, in many cases, converting these weldments to iron castings can offer significant advantages. Seneca Foundry’s iron castings provide exceptional strength, durability, and precision, making them ideal for replacing weldments in various applications. Some benefits of castings over weldment include:

  • Better Quality: Castings are less likely to have defects like missing welds, porosity, and pin holes that can compromise strength and be visually unappealing.
  • More Consistency: Castings are produced using the same tooling each time, which results in more consistent parts with a uniform surface finish.
  • Reduced Cost: Castings are less expensive to produce than weldments, which can reduce the cost per part.
  • Design Flexibility: Castings can be designed with unique shapes and features that are difficult and expensive to recreate with weldments.
  • Reduced Labor Costs: The casting process requires less labor than welding since it doesn't require skilled welders.

Reduced Material usage: Castings can be designed to use material only where it's needed.

The Highest Quality Iron Castings

We understand your need for consistent, high-quality castings. We use a Total Quality Management system that relies on skilled personnel trained in the latest QC procedures, modern testing equipment, and comprehensive process control. This ensures standards, processes, and procedures are in place and working to provide high-quality castings to our customers from start to finish.
