Your Trusted Castings
Partner
Yamaha’s select network of world-class facilities is your go-to, turnkey resource, backed by decades of globally recognized manufacturing excellence.
A Modern Smart Factory Specializing in Investment Casting
YPPI—a division of Yamaha Marine Systems Company, Inc.—is one of the most advanced investment casting facilities in the U.S., guided by the company’s legacy of investment, staffing, and quality. We offer full data traceability, real-time digital monitoring, and in-house tooling, die fabrication, and finishing through a concurrent engineering approach. Our high-capacity shelling system, typically a foundry bottleneck, is available for sublease—allowing qualified partners to operate as if it were their own. With domestically sourced materials and long-term contract options, YPPI provides a secure, scalable alternative to offshore sourcing—ideal for companies seeking tariff protection and reliable onshore production.
Our Core Capabilities
From design and wax forming to casting, machining, and finishing—YPPI controls every stage of the investment casting process to ensure precision, scalability, and consistency.
In-House CAD & Simulation Services
We use SolidWorks® and CREO for precise CAD/CAM modeling and wax mold design, backed by SOLIDCast metal flow simulation. This allows us to optimize castings before production—reducing risk, improving yield, and speeding up development.
Optimizes castings before production—reducing risk, improving yield, and speeding up development.
Pattern Molding Solutions
We offer in-house mold construction and a range of wax injection machines, including high-tonnage options. Our composite wax molds enable complex, customizable shapes, and we support rapid prototyping with 3D printed patterns—delivering test-ready designs in as little as two weeks.

Automated Shelling System
Our automated shelling system handles both high-volume part trees and large mono-shells up to 1000lbs. With capacity for up to 60,000 stacks per year, we support complex, large-scale castings with consistency and efficiency.
Shelling capacity up to 60,000 stacks per year supports consistent, large-scale casting production.
Automated Casting Processes
Our automated pouring system handles castings up to 300 lbs with consistent precision. Post-pour, stainless steel and Al₂O₃ media blasting prepare parts of various sizes for finishing—ensuring optimal surface quality and corrosion resistance at scale.
Ensures optimal surface quality and corrosion resistance at scale.
Automated De-Gating & Grinding
A robotic grinding cell provides consistent, repeatable finishing for parts up to 150 lbs. Multiple wheel sizes and speeds support complex shapes while improving throughput and surface uniformity.
Delivers consistent surface finish and throughput for complex shapes.
Advanced Post-Cast Capabilities
We offer full post-cast processing with 3-, 4-, and 5-axis CNC machining, mirror-finish vibratory and drag polishing, and certified TIG, MIG, and ARC welding for precision assemblies and intricate final shapes.
Supports mirror-finish polishing and complex welded assemblies to final spec.
Our Key Equipment
Specialized machinery enabling precision shelling, finishing, and post-cast operations at scale.
