The Partner Companies (TPC) is a global portfolio of specialty manufacturers offering comprehensive solutions across diverse industries. This article showcases the world of metal fabrication, diving into the exceptional capabilities of two key TPC advanced manufacturing facilities: L&T Precision and Pinnacle Precision.
Excellence In Metal Fabrication
Companies like L&T and Pinnacle make the intricate metal components that power our world, keep us healthy, or ensure our safety. Each company leverages decades of experience, the latest technology, and unmatched expertise to push the boundaries of what’s possible.
Both L&T and Pinnacle are well-versed in serving industry-leading manufacturing companies across many of the most essential sectors, including aerospace, defense, renewable energy, and medical.
The companies feature the highest certifications, including AS9100, ITAR, and ISO9001:2015.
Understanding Metal Fabrication
Metal fabrication is a complex and versatile manufacturing process that transforms raw metal sheets into the intricate components that shape our world. This process encompasses a variety of techniques, combining both traditional craftsmanship and modern technology.
This process is vital for countless industries, from the delicate instruments used in medical procedures to the powerful electronics in defense systems.
At its core, metal fabrication consists of three main stages:
- Engineering
- Fabrication
- Finishing
Our advanced manufacturing centers work with engineers and designers to perfect their CAD plans, ensuring the final product meets all functional requirements and the strictest quality standards.
The fabrication experts at L&T and Pinnacle bring those engineering plans to life, utilizing CNC machines to shape and form sheet metal and fabricate metal parts to the tightest tolerances.
The teams are experts in:
Cutting: Severing metal using various methods, such as lasers, punches, and photochemical etching, to shape the material. Each technique offers different levels of precision and material compatibility.
Bending: Forming the metal into specific shapes using specialized brakes and presses. This process is crucial for creating angles, channels, and boxes.
Machining: The process of removing material from a solid piece of metal to create precise cuts, holes, and shapes using tools like CNC machines, mills, and lathes
Welding: A process that combines separate metal pieces using intense heat to create a permanent bond. Different metals require different welding techniques.
Forming: Shape metal into specific profiles or contours by applying pressure or force.
Punching: Use a punch press equipped with a specialized tool and corresponding dies to create holes in flat metal sheets.
Finishing: Preparing the product for use and enhancing its appearance and durability by deburring, grinding, sanding, powder coating, painting, or plating.
Bringing it Together
L&T and Pinnacle perform value-added services such as contract manufacturing or total assembly to serve their customers better.
The Assembly teams at both locations are experts in integrating hardware, wiring, components, and insulation into the parts they manufacture. They boast a comprehensive process that meticulously joins and integrates metal parts, machined components, and wire harnesses into accurate, functional, and seamless electro-mechanical assemblies.
Our team considers every aspect of the final product, including everything connected or attached to it, to meet the highest functional standards. We match material tolerances and component alignments to ensure that every piece fits together flawlessly and performs its intended function with utmost efficiency and durability.
Pinnacle Precision: A Legacy of Excellence
With a rich history stretching back over 50 years, Pinnacle Precision has established itself as a sheet metal fabrication and total solutions provider. Since 1973, when Don Wright and Ed Randolph opened D&E Precision Sheet Metal, it aimed to provide exceptional prototyping, CNC machining, welding, assembly, painting, and silk screen printing services for the aerospace, audio/visual, medical, and energy sectors — and a core team with over 30 years of expertise.
In 2008, they transformed into Pinnacle Precision Sheet Metal. Since then, they have focused on delivering high-quality parts and working with companies that shape our future in the medical, communications & technology, renewable energy, aerospace, and defense industries. Pinnacle specializes in:
- Precision sheet metal fabrication
- Precision CNC machining
- Finishing
- Total assembly
- Quality Assurance
Their 73,000-square-foot facility in Anaheim, California, boasts multi-axis machining technology, cutting-edge shearing, punching, forming, bending machines, line grainers, and welding stations. This powerhouse equipment fuels efficient prototyping and production runs, delivering exceptional accuracy and cost savings for both individual parts and large-scale projects.
Pinnacle’s commitment to excellence is evident in its focus on safety and investment in employee development. The team is always willing to find innovative solutions for clients without compromising quality control. It ensures that all components comply with ITAR, ISO9001:2015, RoHS certifications, and the AS9100D — one of the most demanding certifications in the aerospace industry.
TPC acquired the company in May 2022. Their partnership helped expand its reach into new service offerings and markets. TPC contributed to Pinnacle’s growth by investing in the latest technologies and machinery, enabling the company to handle larger-scale projects with accuracy and exceptional turnaround times.
L&T Precision: Innovative Solutions in Machining
Located in Poway, California, L&T Precision has evolved from a small shop founded in 1984 by the Nguyen family to a powerhouse of cutting-edge technologies with a more than 50,000-square-foot footprint across North America.
Their state-of-the-art facility offers advanced machining and sheet metal fabrication services for the aerospace, defense, healthcare/medical device, and commercial industries.
L&T Precision emphasizes a culture of solving challenges and – most importantly – making a meaningful impact. Leveraging technology to deliver problem-solving fabrication solutions, they specialize in:
- Contract manufacturing
- Sheet metal fabrication
- Finishing
- Custom manufacturing
- Welding
TPC acquired L&T in December of 2020. Their partnership has allowed L&T to stay at the forefront of modern technology by continuously investing in innovation.
In early 2024, L&T opened a new 50,000-square-foot production facility in Tijuana, Mexico. The expansion reduces customer lead times and freight costs while allowing large-scale production runs of precision sheet metal components and assemblies for the industrial equipment and medical technology industries.
Recently, TPC supported L&T by investing in several new manufacturing machines, including a high-capability Vertical Machining Center and a 3-axis CNC milling machine, to increase its capabilities and service the growing aerospace, defense, and satellite communications markets.
