Two companies. One sixty-year reputation.
Modern Alpha Plastics was formed in 1996 when two of Kansas City's most
respected custom molders merged into a single shop with sixty combined years of
precision injection experience. We've been engineering and molding parts for
America's top manufacturers ever since.

until you're satisfied
Today, Modern Alpha Plastics is led by Anthony C. Gross, President and Chief Engineer.
Anthony brings the design background of a working engineer and the operating discipline of an owner-operator. Most quotes pass across his desk. Most molds get a second look from him before the first shot. That's not a marketing line — it's how a 23-press shop with a 60-year reputation actually runs.
Anthony took the helm following the retirement of the previous Chairman, continuing the operating philosophy that has defined the company since its founding: engineer-led, customer-first, and relentlessly hands-on.

1965 — Modern Plastics Molding founded
Modern Plastics Molding, Inc. begins operations in Independence, Missouri, building a reputation for difficult dimensional plastic parts and tight customer relationships.
1989 — Modern Plastics Molding acquired
The first ownership transition that would lead to the eventual merger.
1991 — Alpha Plastics acquired
Alpha Plastics, Inc. — a Kansas City, Missouri custom molder founded in the early 1960s — is acquired by the same ownership group.
1996 — Modern Alpha Plastics formed
Modern Plastics Molding (31 years in operation) and Alpha Plastics (27 years in operation) merge into Modern Alpha Plastics, Inc., consolidating combined annual sales of approximately $7 million and a reputation for high-quality custom injection molding.
Today — Engineer-led and growing
Anthony C. Gross leads the company as President and Chief Engineer, with two in-house design engineers, 21 active presses, and specialty practices in drone components, legacy OEM re-engineering, and metals-to-plastics conversion.

Our facility at 7200 NE Birmingham Road sits in the Kansas City metro — the geographic center of US logistics. From here, we ship to anywhere in the continental United States by truck, rail, or air with cost and lead-time advantages that coastal molders simply cannot match.
Twenty-one presses share one floor under one roof. Engineering, tooling, production, QC, and shipping all operate within line of sight. When something goes wrong on a press, the engineer who designed the tool can be standing next to it in 90 seconds. That matters when you're chasing a problem at 4:30 on a Friday.

Two generations on the same floor.
Employee longevity is the foundation of how we operate. Several families are represented here by two generations — fathers, sons, and daughters running parts side by side. Operators with twenty- and thirty-year tenures are common. The same operator who started a job at 7 a.m. is often the one who signs off the last carton before it ships.
That kind of continuity is rare in modern manufacturing, and it's a deliberate choice. Tribal knowledge — what a press sounds like when something is wrong, what a resin lot looks like before it's a problem — is the kind of thing you cannot document and cannot buy. You can only earn it over decades of treating the people on your floor like they're worth keeping.
