Every flawless plastic component tells a story of engineering discipline, material mastery and seamless execution. In industries where consistency and speed can make or break a product line, behind-the-scenes manufacturers play a pivotal role in shaping success. Allied General Industries LLC is that partner, powering supply chains with precision-driven plastic injection molding that leaves no room for error.

Built on 50 years of expertise and experience, Allied has helped companies across North America turn ideas into tangible, production-ready components. The company offers custom-engineered solutions, developing and building specialized assembly equipment in close collaboration with clients to meet high-volume production goals. With advanced tools like multi-cavity molds, it delivers high-volume, defect-free parts at competitive costs, all backed by expert craftsmanship, strict quality control, and full compliance with all required permits and local regulations.

“Clients are at the heart of what we do. We take the time to understand their vision, treat each project as one-of-a- kind and go the extra mile to help them succeed,” says Luiz Gastaldo Filho, product development.

Allied supports a diverse clientele, including mid-to-large medical, defense, consumer goods and automotive companies across the U.S., Canada and Latin America. It also supports new ventures and startups throughout the process, from initial sketches to fully realized in-house mold design. Backed by a highly experienced in-house team, the company meticulously oversees mold adjustments and production setup, ensuring every detail meets the highest standards.

Over the past decade, Allied replaced its legacy machines with a cutting-edge fleet of brand-new injection molding machines ranging from 120 to 780 tons. These machines produce components ranging from as small as one gram to as large as four feet long and six pounds. They can now scale production from thousands to millions of units and have even manufactured over 50 million parts for a single client.

This advanced manufacturing capability enables the company to focus on producing various plastic components for clients, either using existing molds or creating new ones. If a client already has molds, the process is even faster: Allied simply transfers them to its facility in Pembroke Pines and begins manufacturing right away. In addition, its 70,000-square-foot facility features ample storage capacity for up to 3,000 pallets, giving clients the convenience of storing their finished products and arranging shipments as needed.

Apart from standard injection molding, the company also offers insert molding, over-molding, ultrasonic welding, hot stamping and direct printing on the manufactured items. It maintains a dedicated quality control department that diligently inspects every lot, keeping thorough records of its findings. Each record helps Allied meet the stringent guidelines often demanded by industries.

Allied’s impeccable facilities and personalized approach fuel its reputation, attracting more clients who value custom-built solutions and individual care. Many prospective clients tour the Allied facility, see firsthand how every project receives custom attention and eventually choose to collaborate with the company—even when the price is the same elsewhere. The longevity of its client relationships speaks volumes, with many clients having been with the company for over 15 years and maintaining a steady cadence of weekly orders.

That’s because the company doesn’t just build plastic units; it builds trust, delivers precisely what’s needed and treats every client like a partner. This rare blend of cutting-edge technology, real expertise and genuine collaboration makes Allied the first call for plastic injection molding solutions—today and into the future.
