What are the recommended types and models of crimping dies or fixtures? Is it mandatory to use a specific type of die?

For crimping terminals, we recommend using the specific crimp tooling that matches the terminal part number and crimp geometry. In practice, this means selecting the correct die set / crimping inserts and the right tooling configuration (press type, locator, anvil, and positioner), rather than using an arbitrary “universal” die.

Recommended tooling type Crimp die set for the given terminal size (conductor barrel and, if applicable, insulation barrel forming) Correct locator/positioner to ensure consistent terminal presentation and die alignment Anvil / shuttle / nest tooling (if your machine uses an anvil concept) to support the terminal body without deformation For insulated terminals, a die set that provides the required conductor crimp formation and insulation strain-relief coverage. Does it have to match a specific type/model? Yes—generally it must match the terminal’s crimp spec, but not necessarily the exact same brand or machine model.

The critical requirement is that the tooling produces crimp dimensions (e.g., crimp height/width or indent depth) within the terminal datasheet tolerance. Tooling must match the terminal part number, wire size, and crimp type (conductor-only vs conductor+insulation crimp). If the terminal uses a distinct crimp profile (e.g., F-crimp, C-crimp, serrated vs round barrel), the die profile must be correct to avoid issues like loose crimp, strand cutting, or low pull-out strength. What we can provide The recommended die set/inserts part numbers (or tooling reference) for your terminal P/N. Crimp machine compatibility guidance (e.g., whether your machine requires a specific die housing style, stroke setting, or locator configuration). Tooling qualification support: gauge checks and a short validation run to confirm CTQs (crimp dimensions, pull-out strength, and electrical continuity/resistance if required). To confirm the exact tooling recommendation, please share terminal part number target wire size (AWG/mm²) and insulation OD your crimp machine model (or tooling system type) and whether it is open-die or closed-die style any existing tooling you want to reuse (if applicable) Once we have these, we can confirm whether the tooling needs an exact die-set or whether a cross-compatible equivalent is acceptable, and we will define the verification steps to ensure compliance.
