Stamping. Welding. Sub-assembly. Tool & die.
Value-added, all in-house.
Clover Group is a Canadian custom metal stamping, metal forming, robotic welding and sub-assembly supplier — serving automotive, brake systems (disc and drum), heavy-duty truck, commercial-vehicle and industrial programs from Concord (GTA / Toronto) and Breslau (Waterloo region). Progressive, transfer and hand-transfer stamping, robotic welder cells and finished sub-assemblies, plus full in-house tool & die build. Every program from RFQ to SOP managed on one APQP workflow.
Metal Stamping & Forming
Progressive-die, mechanical-transfer and hand-transfer metal stamping and forming — 80 to 1,650 tons.
A 30+ press fleet running customer programs from prototype to production. Small fine-blank jobs on 80- and 200-ton lines; mid-volume transfer work on 500–800-ton presses; heavy stamping on the 1,650-ton line for chassis, body and commercial-vehicle components. In-die staking, tapping and nut welding eliminate downstream steps and keep piece price competitive. Custom metal stamping for automotive, heavy-duty truck, brake systems and industrial programs.

Welding
Robotic welders, projection, spot and specialty welding — cell-ready for high-mix programs.
Twelve robotic MIG welder cells run alongside 15+ projection welders and three spot welders. Specialty welding on a Flexfast nut-and-stud welder and a Norton bushing install cell. Every welded part is traceable to its coil. Robotic welding cells deployed across automotive, brake systems, commercial-vehicle and heavy-duty truck programs.

Sub-Assembly
Mechanical automation and manual lines for finished sub-assemblies and modules.
Multi-station assembly lines combining mechanical automation with skilled manual work. Staking, clinching, tapping, grinding and final pack — often integrated directly with the upstream stamping or welding cell for one-piece flow. Kits and sequenced shipments for module integrators and OEMs.

Tool & Die Build
Full in-house tool and die shop — Clover started here in 1979 and never stopped.
Clover Tool was founded as a tool and die shop and remains a full-service tool builder today. We design and build progressive dies, mechanical-transfer dies, hand-transfer dies, prototype tooling and weld fixtures in-house. We build for our own presses and, when timing helps a program, for customer production lines. Rapid try-out on the same press the production tool will run on. Calibrated CMM and scanning-arm inspection on every die. The tool room handles repair, retro-fit and engineering changes for tools that have been in service for decades.

Asked on most first calls.
The questions buyers and program engineers usually open with. Anything else, ask us directly.
What press tonnage range does Clover Group run?
Our press fleet spans 80 to 1,650 tons across 30+ presses, covering progressive-die, mechanical-transfer and hand-transfer stamping. The 1,650-ton line handles heavy chassis and body components; small-tonnage lines run high-volume hardware.
Do you design and build your own tooling?
Yes. Clover started as a tool and die shop in 1979 and still designs and builds progressive dies, mechanical-transfer dies, hand-transfer dies, prototype tooling and weld fixtures in-house, with wire EDM and tool-room CNC. Try-out happens on the same production press the tool will run on.
What production volumes can you support?
From prototype and low-volume runs to several million parts per year. Dedicated progressive lines run high-volume programs around the clock, while transfer and hand-transfer presses cover mid- and low-volume work.
What materials do you stamp and form?
Low-carbon steel, HSLA, advanced high-strength steel (AHSS), stainless steel, aluminum, and brass and copper alloys. Heavy-gauge material up to .500" (13 mm) runs at our Ultramet facility.
What quality certifications do you hold?
Our Business Management System conforms to IATF 16949:2016, ISO 9001:2015 and ISO 14001:2015. Every program runs the five-phase APQP workflow with customer-approved PPAP, and every part is traceable from coil to shipment.
Where are your facilities located?
Two Ontario plants: Clover Tool Mfg. in Concord (Greater Toronto Area, minutes from the 400/407) and Ultramet Industries in Breslau (Waterloo Region, near Kitchener-Waterloo and Cambridge).
How quickly do you respond to an RFQ?
