Precision Sheet Metal Forming
MJM Manufacturing operates nine Amada CNC press brakes and forming machines plus three Knuth plate rollers — an all-Amada forming department bending everything from thin-gauge aluminum to 240-ton, 14-foot heavy plate for aerospace, defense, robotics, OEM and industrial customers, all under one roof in Miami Gardens, Florida.
Overview
Why MJM Precision Forming
Precision forming is where flat, laser-cut blanks become real parts — and accuracy at the brake decides whether holes line up, flanges meet, and assemblies bolt together the first time. A part can be cut perfectly and still fail at assembly if the bends are off by half a degree. That is why MJM treats forming as a precision discipline in its own right, not an afterthought to cutting.
MJM Manufacturing runs an all-Amada forming department: six Amada RG 80 CNC press brakes (80-ton), two Amada EG 4010 servo-electric machines for the tightest-tolerance work, and a 240-ton Amada HRB 2204 with a 14-foot bed for long parts and heavy-gauge material. Three Knuth plate rollers in 3-, 4- and 7-foot widths add cylindrical and curved forming to the department.
Every job is programmed offline with 3D bend simulation before the first part is ever bent — setups are faster, first articles come out right, and production runs stay repeatable. Common Amada tooling across the entire line means any job can move to any machine without re-engineering, so scheduling stays flexible and lead times stay short. We have been forming sheet metal in South Florida since 1979, and forming runs in-line with laser cutting, punching, welding, hardware insertion and finishing — one building, one purchase order, one point of accountability.
Advantages
The Benefits for Your Parts
CNC-controlled Amada brakes with offline programming hold consistent bend angles across the whole run — part 1 and part 1,000 match.
Servo-electric EG 4010 machines form the most precise parts without hydraulic drift — ideal for aerospace and robotics work.
A 240-ton, 14-foot Amada HRB 2204 forms long chassis, panels and heavy-gauge plate most local shops can’t touch.
Three Knuth plate rollers in 3-, 4- and 7-foot widths roll cylinders, sleeves and radiused panels.
3D bend simulation catches collisions and layout issues before the first bend — fewer surprises, faster first articles.
Forming runs alongside laser cutting, punching, hardware, welding and finishing — no freight between processes.
The Process
How We Form a Part
Flat pattern & bend deductions: Before anything is bent, we develop an accurate flat pattern using real bend deductions for the exact tooling and material — so the finished dimensions match your drawing, not a generic approximation.
Offline programming & 3D simulation: The bend sequence is programmed and simulated in 3D away from the machine. Collisions, tool interference and unreachable bends show up on screen, so the first physical part is right instead of a test piece.
Tooling selection: We choose punch and die combinations for your material, thickness and radius — and because our tooling is common across the Amada line, the job can run on whichever machine fits the schedule.
First-article verification: The first formed part is checked against your print before the run continues, with angles and critical dimensions confirmed on our CMM and optical inspection equipment.
Production & in-line handoff: Once the setup is proven, the run is formed to the same standard start to finish, then moves straight into welding, hardware insertion or finishing — no freight, no waiting on an outside vendor’s queue.
Applications
What We Form
Aerospace & defense components: Brackets, chassis details and structural parts formed to drawing with full lot traceability — AS9100 certified, ITAR registered, MIL-I-45208A compliant inspection.
Enclosures & housings: NEMA boxes, electronics enclosures, server and kiosk panels formed square and hardware-ready, feeding straight into our welding and finishing departments.
Precision brackets & chassis: Robotics and OEM assemblies — including chassis and power supply enclosures — where hole-to-bend accuracy decides fit. Servo-electric precision on the tightest work.
Rolled & curved shapes: Cylinders, sleeves and curved panels rolled on Knuth plate rollers up to 7 feet wide.
Panels, covers & skins: Formed returns, hemmed edges, offsets and stiffening ribs on cosmetic and functional panels that have to look right and stay flat.
Materials
Materials We Form
Different metals behave very differently at the brake — grain direction, springback and minimum radius all change with the alloy and temper. We form the full range of production sheet and plate, and account for each material’s behavior in the flat pattern and tooling.
Aluminum (5052, 6061, 3003), cold-rolled and hot-rolled steel, stainless steel (304, 316, 316L), galvanized and galvannealed steel, copper, brass, beryllium copper and titanium — from thin decorative gauge up to heavy plate on the 240-ton brake. When a material choice or radius will fight the forming process, our design-for-manufacturability review flags it before production, so you avoid cracked bends and costly revisions.
Certified Quality
Forming Credentials
MJM’s forming department runs under the same quality system as the rest of the shop: AS9100 certified, ISO 9001 certified, ITAR registered, MIL-I-45208A compliant inspection, and full lot traceability from raw material to finished part. An all-Amada line — consistent tooling, offline programming and 3D bend simulation — operated since 1979 from our 44,000 sq ft facility in Miami Gardens, Florida. Whether you need one first article or a repeating production run, the same discipline and documentation apply. View our full certifications.
FAQ
Precision Forming FAQ
What press brake capacity does MJM have?
Nine Amada machines: six RG 80 80-ton CNC press brakes, two EG 4010 servo-electric forming machines, and one HRB 2204 hydraulic brake with 240 tons over a 14-foot bed — plus three Knuth plate rollers in 3-, 4- and 7-foot widths.
How does MJM ensure bend accuracy?
Every job is programmed offline with 3D bend simulation before the first part is bent, so collisions and layout problems surface on screen, not on your material. CNC control and servo-electric machines hold angles consistently across the entire run, and first articles are verified on CMM and optical inspection.
Can you form long or heavy-gauge parts?
Yes. The Amada HRB 2204 delivers 240 tons across a 14-foot bending length — long chassis, large panels and heavy-gauge plate that exceed most local shops’ capacity.
What materials can MJM form?
Aluminum, cold-rolled and stainless steel, galvanized and galvannealed steel, copper, brass, beryllium copper and titanium — from thin gauge up to heavy plate on the 240-ton brake, with each material’s springback and grain direction accounted for in the flat pattern.
Do you handle cutting and forming together?
Always. Blanks come off our five Amada fiber lasers or CNC turret punch and go straight to the forming department — then on to hardware, welding and finishing — all in one Miami Gardens facility, on one purchase order.
