The Danfoss FT1330 Crimp Machine is a specialized hydraulic crimping device designed for assembling hose fittings. It is available in two models, A and B, each with distinct capabilities and specifications.
Function Description:
The primary function of the Danfoss FT1330 Crimp Machine is to securely crimp hose fittings onto various types of hoses, creating reliable hose assemblies. The machine uses a hydraulic cylinder to apply pressure, deforming the fitting around the hose to create a tight, leak-proof connection. It is designed for both field and factory crimping applications.

- FT1330-1-2-6: Motor 1 HP, 220 Volt, 50/60 Hz, 1 ph
- Crimp Die: One Crimp Die Cage per setup (eight dies included in one cage assembly).
Usage Features:
- Ease of Installation: The machine is delivered fully plumbed and wired, with the reservoir filled with 10 weight hydraulic oil. It requires installation on a solid bench capable of holding 245 pounds, with a recommended height of 36". Secure anchoring to the bench is required using four 5/16 inch bolts.
- Simple Operation: The machine is operated by a toggle switch on the front of the cabinet and a foot switch for crimping. The jog reverse button allows for cylinder retraction.
- Die Cage System: Crimp dies are contained in pre-assembled die cages, which can be easily inserted into the machine, eliminating the need for individual die insertion and reducing the risk of inter-mixing dies.
- Digital Encoder: The machine features a digital encoder for precise crimp diameter settings, allowing for accurate and repeatable crimps.
- Crimp Diameter Chart: Users should refer to the Danfoss PowerSource Crimp Spec Tool (danfoss.com/crimp) for specific crimp details, including the proper die cage part number and crimp diameter settings for various hose series, sizes, and fitting styles.
- Adjustable Return Stroke: For repetitive crimping tasks, the return stroke of the cylinder can be shortened by using the jog reverse button, which helps to reduce machine cycle time.
- Hose Preparation: The manual provides detailed instructions for hose preparation, including cutting to length and skiving (if required for flat factory crimp).
- Fitting Locator: The machine includes a fitting locator to ensure proper positioning of the fitting within the dies for consistent crimps. For certain hose styles (e.g., Teflon, Thermoplastic, Factory Crimp Style), a positive backstop feature can be engaged by placing a locator collar in a specific recess, preventing fitting movement during crimping.
- Crimping Procedures: Step-by-step instructions are provided for various crimping styles, including Factory Crimp Style (2-piece fitting), Thermoplastic Style (1-piece fitting), Flat Field Crimp Style (1-piece fitting), and Barrel Field Crimp Style Hose Assemblies. Each procedure covers hose preparation, machine setup, die cage insertion, digital encoder setting, fitting positioning, crimping, and checking the crimp.
Maintenance Features:
- Cleanliness: Sliding surfaces must be kept free of dirt and abrasive materials to ensure smooth operation and prevent wear.
- Lubrication: Crimp dies and the crimp ring surfaces that make metal-to-metal contact should be lubricated with high-efficiency PTFE grease (Danfoss part number T-400-G) at the start of each production run, or at least once per 25 crimps (more often for larger hoses).
- Corrosion Prevention: All exposed black metal surfaces should be coated occasionally with a light film of oil to prevent corrosion.
- Hydraulic Oil Level Check: The fluid reservoir's oil level should be checked periodically and maintained at one inch below the top of the reservoir. SAE 10 weight hydraulic oil should be added as necessary, ensuring the crimp die cage is fully retracted during the check.
- Troubleshooting Checklist: A comprehensive troubleshooting guide is included to address common issues such as the motor stalling during crimping, inconsistent crimp diameters, and machine not cycling. This includes checks for electrical supply, hydraulic pressure, transducer function, and control board issues.
- Calibration Procedure: Detailed steps are provided for machine calibration, including transducer adjustment, digital encoder setting, and span screw adjustment, to ensure accurate crimp diameters.
- Die Cage Assembly Instructions: Instructions are provided for assembling the die cage, emphasizing cleanliness, proper lubrication of components, and correct installation of springs, roll pins, and crimp dies.
