IDO Technology worked on a base sheet stamping die project for an international home appliance manufacturer in Mexico. The tooling covered five operations: piercing, cutting, embossing, bending, hole flanging and flattening.
The project combined the forming sequence with die guidance, plate connections, scrap discharge and sensor installation. A key part of the work was reviewing the customer’s initial die structure before recommending an alternative arrangement.
The large tooling dimensions presented a challenge for the customer’s initial proposal. During the design review, IDO identified significant risks to die stability and structural strength.
These concerns prompted IDO to recommend an alternative structural design. The focus was on meeting the structural requirements of the large die assembly while accommodating the base sheet forming sequence.
The base sheet required five stamping operations:
|

OP10 |
Piercing / Cutting / Embossing |

OP20 |

The feeding height was 375 mm, and the die shut height was 620 mm. Including the base plates, the OP10–OP30 section weighed 11,400 kg, while the OP40–OP50 section weighed 6,000 kg.

The individual upper and lower die weights exclude the base plates. The two section totals include the base plates.
Die guidance and plate connections
IDO selected MISUMI guide pillars, drawing on experience with similar guide arrangements. The engineering assessment found their strength sufficient for the proposed structure.
The plate assembly combined welded connections with M16 screw fastening at the upper and lower interfaces.
Scrap discharge
Conveyor belts and scrap chutes provided a route for carrying scrap directly outside the press. This arrangement addressed scrap removal alongside the forming operations.
Sensor installation
The illustrated die arrangement included four sensors at designated mounting positions.
The review established a clear recommendation: use an alternative die structure to address the stability and strength risks identified in the customer’s initial proposal.
For this project, IDO’s contribution extended beyond arranging the stamping operations. It included evaluating the customer’s concept and developing a tooling configuration with defined installation dimensions, die guidance, plate connections and scrap discharge provisions.
