1. Introduction
This manual provides instructions for the proper use and maintenance of the haisstronica Crimping Die for Non-Insulated Terminals, designed for wire sizes ranging from AWG 22 to 8. This die is intended for use with compatible crimping tools, such as the haisstronica HS-8327, to create secure electrical connections.
2. Safety Information
Always observe basic safety precautions when working with electrical tools and components. Failure to do so may result in injury or damage to equipment.
- Wear appropriate personal protective equipment, including safety glasses, to protect against flying debris.
- Ensure the crimping tool is clean and in good working condition before use.
- Disconnect power from any electrical circuits before performing crimping operations.
- Keep hands and fingers clear of the crimping jaws during operation.
- Use the correct die for the specific terminal and wire gauge to prevent improper crimps.
3. Product Overview
The haisstronica Crimping Die is engineered for precision and durability. It is specifically designed for non-insulated wire terminals across a wide range of American Wire Gauges (AWG).

Key Features:
- Wire Compatibility: Designed for non-insulated wire terminals from AWG 22 to AWG 8.
- Durable Construction: The die surface features chromium plating for corrosion resistance and strength.
- Interchangeable Design: Allows for quick swapping with other dies, eliminating the need for multiple fixed-die tools.
- Compatibility: Intended for use with haisstronica crimping tools, such as model HS-8327 (sold separately).
4. Installation
To install the crimping die into a compatible haisstronica crimping tool:
- Ensure the crimping tool is open and disengaged.
- Locate the two screws on the crimping tool that secure the existing dies.
- Using an appropriate screwdriver, loosen and remove these screws.
- Carefully remove the old dies (if any) and position the haisstronica Crimping Die (Model HS1578/HX1578) into the designated slots. Ensure the die is oriented correctly with the AWG markings visible and facing outwards.
- Insert the two provided screws and tighten them securely. Do not overtighten.
- Test the die by closing and opening the tool to ensure smooth operation and proper alignment.
5. Operation
Follow these steps to perform a crimp using the haisstronica Crimping Die:

- Prepare the Wire: Strip the insulation from the end of the wire to the appropriate length for your non-insulated terminal. Ensure the stripped wire strands are clean and untwisted.
- Select the Correct Terminal: Choose a non-insulated terminal that matches the wire gauge (AWG 22-8) and the application requirements.
- Insert Terminal into Die: Place the non-insulated terminal into the correct slot on the crimping die that corresponds to its size.
- Insert Wire into Terminal: Insert the stripped end of the wire fully into the terminal. Ensure no stray strands are outside the terminal barrel.
- Perform the Crimp: Squeeze the handles of the crimping tool firmly and steadily. The tool's ratchet mechanism will engage and prevent the handles from opening until a complete crimp is achieved. Continue squeezing until the ratchet automatically releases.
- Inspect the Crimp: After the crimp is complete, remove the terminal and inspect it. The crimp should be tight and secure, with no loose wire strands. Perform a gentle tug test to ensure the wire is firmly held within the terminal.
6. Maintenance
Proper maintenance ensures the longevity and performance of your crimping die.
- Cleaning: After each use, wipe the crimping die with a clean, dry cloth to remove any debris or residue.
- Lubrication: Periodically apply a light coat of machine oil to the moving parts of the crimping tool and the die to ensure smooth operation and prevent rust.
- Storage: Store the crimping die in a dry environment to prevent corrosion. If removed from the tool, store it in its original packaging or a protective case.
- Inspection: Regularly inspect the die for any signs of wear, damage, or deformation. Replace the die if any damage is observed to ensure consistent and reliable crimps.
7. Troubleshooting
If you encounter issues during operation, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Crimp is loose or weak | Incorrect die size for terminal/wire; Insufficient pressure applied; Damaged die. | Ensure correct die slot is used for the wire and terminal size. Apply full pressure until ratchet releases. Inspect die for damage and replace if necessary. |
| Wire pulls out of terminal | Incomplete crimp; Wire not fully inserted; Incorrect terminal size. | Ensure the wire is fully inserted into the terminal barrel before crimping. Complete the crimp cycle until the ratchet releases. Verify terminal and wire gauge compatibility. |
| Die does not close properly | Obstruction in jaws; Die not correctly installed. | Inspect jaws for debris and clean. Re-install the die, ensuring screws are tightened and it sits flush. |
| Die shows signs of rust | Improper storage; Lack of lubrication. | Store in a dry environment. Apply a light coat of machine oil periodically. |
