NEW MOLD CONSTRUCTION
Precision Mold Manufacturing
MSI delivers complete, end-to-end mold manufacturing capabilities — 250-6,600 tons — combining advanced technology, skilled craftsmanship, and proven processes to build high-performance tooling for a wide range of applications. From initial engineering release through final validation, every mold is built with precision, durability, and long-term performance in mind.
Our mold-making capabilities include the full spectrum of in-house operations required to produce complex tooling. This includes high-speed CNC machining, deep-hole drilling, EDM (both sinker and wire), precision grinding, and expert benching and assembly. Each phase is supported by rigorous quality control processes to ensure every component meets exact specifications and seamlessly integrates into the final tool.
MSI’s team brings deep experience in building molds for a variety of processes, including injection molding, structural foam, gas assist, blow molding, and other specialized applications. This breadth of expertise allows us to tailor each tool to the specific performance, material, and production requirements of the program.
Large Tonnage Mold Expertise
A key differentiator is MSI’s capability and experience in large tonnage molds. We are equipped to design, build, and manage complex, large-scale tooling programs that demand robust construction, tight tolerances, and precise coordination across multiple systems. Our facility, equipment, and team are structured to handle the size, weight, and complexity of these molds, while maintaining the same level of accuracy and attention to detail expected in smaller tools.
Large tonnage mold capabilities include:
Engineering and structural design for high-pressure, large-part applications
Machining and handling of large mold bases and components
Advanced cooling, gating, and flow strategies for consistent part quality
Integration of complex actions, slides, and lifter systems
Thorough validation through in-house sampling and tryout
Whether building standard or large-scale molds, MSI focuses on delivering tools that run efficiently, produce consistent quality parts, and stand up to the demands of production environments. Our commitment to craftsmanship, combined with advanced manufacturing capabilities, ensures every mold is built right the first time and ready to perform from day one.
