M&M Tool And Mold

What M&M Tool And Mold does

M&M Tool And Mold LLC is a privately held US custom mold manufacturer founded in 1995 and headquartered at 3300 Commodity Lane in Green Bay, Wisconsin. The firm specializes in small-to-medium-sized injection molds rated up to 500 tons of injection pressure, serving plastics injection molders across medical, automotive, and consumer goods verticals. Adjacent capabilities include die cast tooling for aluminum, zinc, and magnesium, hot runner systems, multi-shot molding, insert molding, auto-unscrewing tools, and rotary platen configurations, alongside prototype tooling (proof-of-concept and proof-of-process).

The shop is built around conventional precision manufacturing technology rather than proprietary platforms: CNC machining, EDM (Electrical Discharge Machining), high-speed milling on Roeders DGM600 and RXP600DSH 3-axis and 5-axis machines, Zeiss Duramax CMM inspection, and System 3R Macro Combi Pallets with a robotic electrode changer for an integrated electrode machining cell. Engineering workflow runs on PTC Pro/Engineer CREO with Pro-Man and Pro-Mold, which links part design, mold design, and NC tool path creation without data translation. An internal E2 project tracking system provides dashboard visibility into time, hours, and dollars per job. Lights-out automation is deployed to extend unattended machining capacity.

Revenue is generated on a project-based, custom-quotation model with no public pricing tiers; quotes are typically returned within two business days. The GTM motion is direct B2B enterprise field sales, with customers submitting RFQs through the company website or downloadable form and M&M's engineering team collaborating on part review and design before build. Ancillary recurring service lines include mold repair, Engineering Change Notices (ECNs), and a Downtime Prevention preventative maintenance program. The customer base is concentrated among a small set of named enterprise accounts (Engineering Industries, Cast Products, Tsubaki KabelSchlepp America, Master Lock Company), with relationships measured in 8-15+ years. Certifications include ITAR (CAGE Code #95324), Q-MED, and AMBA, and the firm has been recognized multiple times as a Leadtime Leader award winner by MoldMaking Technology Magazine.

Products and services

• Custom Injection Mold Building Expertly crafted small-to-medium-sized custom injection molds up to 500 tons injection pressure, serving plastics injection molders in automotive, medical, consumer goods, and industrial end markets.
• Hot Runner Molding Hot runner tool molding that reduces or eliminates plastic usage associated with conventional cold runner tools, lowering costly plastic scrap despite higher initial investment.
• Die Cast Tooling Single and multi-cavity tooling for the die cast industry using aluminum and zinc with Techmire and Dynacast insert sets, plus dedicated tooling for magnesium molders.
• Multi-Shot Injection Molding Molds that produce multiple layers of plastic to form completed parts with different colors, materials, permanent markings, clear windows, or flexible sealing areas.
• Insert Molding Molds that encapsulate non-molded components such as threaded inserts, electrical contacts, or wired sensors within the molded plastic part.
• Prototype Tooling (Proof of Concept and Proof of Process) Rapid tool build proof of concept tooling that molds parts nearly identical to the proposed final molded part, and complete single-cavity proof of process tooling that matches the proposed production tool features so molders can prove their molding process and shrinkage.
• Conventional Plastic Injection Molds Standard molds ranging from open-and-shut tooling with flat parting lines to complex parting line transitions with multiple mechanical or hydraulic actions.
• Mold Repair Services Full mold repair options ranging from broken ejector pins to damaged manifold systems, including complete inspection and costing proposal prior to repairs.
• Engineering Change Notice (ECN) Services Complete ECN quotation and tooling services for modifications to existing molds, with dedicated staff committed to meeting customer requirements and lead times.
• Downtime Prevention Program Proactive maintenance program including mold disassembly, thorough cleaning, burr removal, and detailed inspection reports with pictures of worn items and repair estimates.
• Concurrent Engineering Services Collaborative engineering approach in which M&M's engineering and design team works with the customer to design and plan the most effective means of producing the highest quality parts, with progress reports provided throughout the tool build.
• Reverse Engineering Services Reverse engineering capabilities to design and build molds from existing parts when 3D CAD or 2D drawings are unavailable, using CMM to verify the new design against actual steel.
