Plastic Injection Molding Tooling: Precision, Low Cost & 0 PPM Quality

At HRB Industries Corporation, we are dedicated to crafting the highest quality plastic injection molding tooling. In the plastic injection molding business, the quality of the mold is the single most critical factor determining the success of the entire production process—affecting part consistency, cycle times, scrap rates, and overall profitability. We understand this responsibility and are completely committed to creating molds that set the standard for precision, durability, and performance.

Our process begins with a thorough consultation with each client. We meet to learn the specific requirements of their project—including part geometry, material selection, production volume, tolerance expectations, and budget constraints. This collaborative discovery phase ensures that we fully understand the application and can develop a tooling solution that meets both technical and commercial goals. Once we receive the criteria, we draw on our many years of experience in CNC machining and metal fabrication to design and produce molds that are as affordable as they are strong and precise.

Our modern manufacturing plant is equipped with the most advanced technology available for mold making—including high-speed CNC milling, EDM (electrical discharge machining), precision grinding, and wire cutting. These capabilities allow us to achieve extremely tight tolerances and complex geometries with exceptional repeatability. Every aspect of the molds we build is optimized to create maximum value for our customers, from gate design and cooling channel layout to ejection systems and wear-resistant coatings.

We owe much of our success to our team of highly skilled engineers, many of whom have trained at some of the world's best educational institutions. Their expertise in material science, thermal dynamics, and mechanical design ensures that every mold we produce performs reliably over millions of cycles. Quality is deeply embedded in our culture, and it is evident in every stage of our operations. Our Black Belt Quality Assurance team implements comprehensive quality control protocols—from raw material verification and in-process inspections to final dimensional and functional testing—ensuring that every product is truly Quality Insured. At HRB Industries, plastic injection molding tooling is not just a product; it is a promise of excellence.
