At Cast7’s Minnesota-based foundry, we specialize in producing high-performance stainless steel and wear components with precision and consistency. From concept to completion, we offer end-to-end solutions supported by advanced processes, environmental friendly technologies, and experienced craftsmanship.
Tool & Pattern Making
We provide full tooling support, including:
On-site pattern design coordination
3D CAD modeling and simulation
Fast turnaround for prototyping or production runs
Tooling built using CNC machined accuracy
Whether you’re developing a new part or converting from another process, our team ensures optimal pattern design for casting success.
Molding & Casting Process
Environmentally Friendly Molding with Ceramic Sand & Sodium Silicate.
Our primary molding process uses ceramic sand bonded with sodium silicate, providing:
Superior dimensional accuracy
Excellent surface finish
Zero harmful chemical binders
Reduced waste and environmental impact
We utilize highly automated vertical & horizontal molding lines
Melting process
We have two one-ton coreless induction furnaces.
We utilize batch melting to meet customer-designated product specifications.
This clean, efficient process is ideal for stainless steel and alloy applications requiring precision and performance.
Heat Resistant Stainless Steel Alloys Poured
We pour a wide range of stainless steel and specialty alloys, including:
HD, HH, HI, HK, HL, HP
Wear Component Alloys
Chrome Irons
Ni-hard
Custom Alloys – Poured to meet specific wear, heat, or corrosion requirements based on customer specifications.
We work closely with customers to select the right alloy for the application—balancing durability, machinability, and cost.
Machining & Heat Treating
We offer integrated post-casting services through trusted partners and in-house coordination:
Machining – on-site precision CNC or manual machining to your print
Heat Treating – Stress relief, solution annealing, and hardening to meet your mechanical property needs
Finishing
Multiple robotic grinding cells
Waterjet-dual head
Quality Control Methods
Spectrographic analysis for alloy verification
In-process verification during molding, pouring, and cooling
Hardness testing
Visual and dimensional inspections on every casting
Final documentation and certifications available upon request
