Customers might not ask how a foundry keeps production running without interruption—but they notice when orders arrive on time and pricing stays steady.
That consistency doesn’t happen by chance. It’s the result of systems designed to keep operations moving even when equipment needs repair or maintenance.
Redundant assets like backup machines, alternative production lines, and overlapping capabilities are the quiet safeguard behind dependable lead times and competitive costs. They’re about preparedness, ensuring work continues seamlessly no matter what challenges arise.
Redundancy in action
From facility layout to the smallest operational details, Greg Whitman, President of Spuncast, says redundancy in their operations is critical to the commitments they’ve made to their customers.
“We have two foundries on site, two machine shops, two heat treat departments, and maintenance facilities throughout to support them. That way, if the primary method was to go down, production doesn’t stop.”
The concept extends well into the details of every area. Each department is equipped with multiple pieces of critical equipment—seven or eight furnaces for heat treat, multiple turning and boring machines in the machine shop, and several casting machines in the foundry.
“We don’t just have one backup machine,” Whitman says. “We have two or three. And we’re constantly upgrading to newer technology so that if we have to pivot, we can do it without missing a beat.”
This redundancy allows Spuncast to:
- Shift production instantly if a machine goes down
- Customize production runs based on batch size, temperature, or diameter
- Keep bottlenecks from slowing the entire workflow
For high-volume parts, such as hydraulic cylinder bodies for off-highway mining trucks, this flexibility is essential. These components are produced in quantities of 100–300 per month, and any interruption could impact a truck builder’s production schedule.
Where it matters most
Every department gains from redundancy, but Whitman points to one area as especially critical: maintenance.
“When a maintenance problem happens, how fast you respond is imperative,” he explained. “Our ability to move a job to another piece of equipment if needed keeps us on schedule, regardless of how long the repair takes.”
Redundancy in maintenance solves problems quickly, but preventing production slowdowns in the first place requires smart design and tooling.
That’s where permanent molds come in. Thousands of permanent molds of a variety of diameters and lengths offer multiple backups per part, keeping production moving even if a single mold is damaged.
And because the molds required for most specifications are already available, customers avoid the time and expense of reproducing tooling for repeat orders, resulting in faster turnarounds.
The customer benefit: Reliable delivery and costs
Redundant assets are a major contributor to cost efficiency too. It’s backup that allows the foundry to maintain full production capacity in most situations. Instead of pausing operations or paying rush fees to outsource, production can simply shift to a backup line. This keeps cycle times consistent and prevents bottlenecks that often drive up costs.
For customers, that stability translates into predictable pricing and fewer surprises in their own scheduling. In industries like steel mills, mining, and energy—where downtime can cost thousands of dollars per hour—knowing your casting supplier can deliver on time ensures not only convenience but a competitive advantage.
But, redundancy offers more than just disruption prevention and cost savings on parts; it also benefits customers by reducing their need for large “just in case” inventories. This frees up their capital while still protecting their operations from supply interruptions.
Additionally, according to Whitman, Spuncast takes the extra step to improve cost-efficiency by cross-training operators to run multiple machines, which multiplies output without increasing labor costs. The results speak for themselves: machine product lead times have held steady between six and eight weeks for over five years.
“If one person can run two machines, that’s 200% of the work,” he said. “If they can run four, you’ve doubled efficiency again. That keeps costs down for our customers.”
Planning ahead
Integrating redundancy isn’t a last-minute decision—it’s the result of long-term capacity planning, equipment lifecycle tracking, and historical demand analysis.
Foundries that adopt this approach often maintain detailed records on machine utilization rates, wear patterns, and lead times for replacement parts, allowing them to forecast when additional equipment or updated models will be needed.
At Spuncast, new equipment is added regularly to address bottlenecks. The team works to standardize brands and controls across the facility, which cuts back on retraining and allows for shared replacement parts.
“The technology improves every year,” said Whitman. “Our job is to get it in here fast enough to be a benefit—before the next round of new technology comes out.”
This forward-looking mindset helps align equipment availability with customer demand spikes, seasonal cycles, and planned product launches. It also creates opportunities to trial new tooling or process improvements without risking a production backlog.
By anticipating both routine and outlier scenarios, the foundry ensures its operations—and by extension, its customers’ supply chains—stay resilient even in the face of market fluctuations or raw material delays.
The unseen advantage
In the centrifugal casting industry, building redundancy into operations reflects a deeper commitment to engineering discipline and customer success.
It’s the result of anticipating challenges before they occur, designing processes that maintain momentum under pressure, and continually investing in the tools and talent that keep production moving. This approach doesn’t just protect schedules—it shapes a supply chain customers can count on, no matter the complexity or urgency of the job.
Customers may never notice all the backup systems in place, but they do notice the results: consistent quality, on-time delivery, and competitive pricing.
