JMK tube marking and terminal crimping machines automate the preparation of identified wires for switchgear, electrical control cabinets and power distribution equipment. The system combines wire cutting, stripping, laser marking, number tube insertion, heat shrinking and multi-station terminal crimping within one production line.
Designed for secondary wiring applications, the equipment produces cut-to-length wires with clearly marked sleeves and crimped terminals. This reduces the need to transfer wires between separate cutting, marking, threading and crimping workstations.
Secondary wiring preparation traditionally requires several independent operations. An operator cuts the wire, strips both ends, prints the identification sleeve, threads the sleeve onto the correct wire and then crimps the specified terminal.
A fully automatic tube marking insertion crimping machine coordinates these operations through one programmed workflow:
Select the required wire color
Feed the wire to the programmed length
Cut and strip one or both ends
Laser-mark the identification information
Cut the number tube to length
Insert the marked tube onto the wire
Position and shrink the tube
Feed the specified terminal
Crimp one or both wire ends
Check the configured process conditions
Collect the completed wire
Combining these operations helps reduce manual sorting and avoids repeated handling of partially processed wires.
Clear wire identification is important when a control cabinet or switchgear assembly contains many visually similar wires. Incorrect or unclear labels can slow installation and make later maintenance more difficult.
The JM-201U uses an industrial laser marking system to apply identification information to the number tube. Laser marking does not require ink or printing ribbon, reducing dependence on printing consumables.
The system can coordinate:
Number tube feeding
Laser marking
Tube cutting
Single-end or double-end tube insertion
Tube positioning
Heat shrinking
Wire and marking sequence control
The appropriate tube material, diameter, length and marking contrast should be tested before production.
Different wires within the same control cabinet may require different terminals. Stopping the machine for frequent applicator changes can reduce output and increase setup errors.
The JM-201U is equipped with four terminal crimping stations as its stated standard configuration. This allows the machine to process several terminal specifications within the same production system.
Its multi-station design supports:
Up to four terminal crimping stations
Programmable selection of the required crimping station
Single-end or double-end terminal processing
Different terminal combinations
Automatic switching between production specifications
Reduced manual terminal and die changeovers
Terminal compatibility must be confirmed using the actual terminal, applicator and crimp specification.
Secondary wiring systems often use different wire colors to distinguish circuits, voltage levels or functions. The JM-201U supports up to 10 wire colors in its stated configuration.
The control system selects the required wire according to the stored production program before cutting, marking and crimping.
Multi-color wire feeding is useful for:
Control cabinet wiring
Switchgear wiring
Power distribution cabinet wiring
Electrical panel assemblies
Industrial automation cabinets
Equipment internal wiring
Wire color selection should follow the customer’s electrical design and production list rather than relying on a fixed general sequence.
The JM-201U is designed for small and medium secondary wires rather than large high-voltage power cables.

Actual output depends on the wire length, number tube process, terminal combination and inspection configuration.
The machine can be configured for different finished-wire structures, including:
Single-end stripping and crimping
Double-end stripping
Double-end number tube insertion
Double-end terminal crimping
Different terminals at each wire end
Marking and heat shrinking at one or both ends
Multiple wire colors within the same production order
A double-ended tube marking insertion crimping machine is suitable when both wire ends require identification and terminal installation before cabinet assembly.
Accurate cutting and stripping are necessary before sleeve insertion and terminal crimping. Incorrect wire length can interfere with cabinet routing, while conductor damage can reduce the reliability of the crimped connection.
The machine allows the required cutting and stripping dimensions to be stored with the corresponding wire color, marking data and terminal selection.
Processing parameters should be validated for:
Wire cross-section
Insulation thickness
Insulation hardness
Required finished length
Front stripping length
Rear stripping length
Full-strip or partial-strip requirements
Terminal barrel dimensions
Processed samples should be checked after every change in wire or terminal specification.
Selected configurations can be equipped with optional crimp force monitoring and CCD visual inspection.
Crimp force monitoring compares the force curve generated during terminal crimping with the established process range. It can help detect conditions such as missing wire, abnormal terminal feeding or significant changes in the crimping process.
CCD visual inspection can be configured for selected visible characteristics, depending on the wire, terminal and inspection position.
Available detection functions may include:
Air-pressure monitoring
No-wire detection
No-terminal detection
Wire cutting length detection
Optional crimp force monitoring
Optional CCD visual inspection
Processing fault alarms
These functions support in-process quality control but do not replace scheduled pull-force testing or crimp cross-section analysis.
A number tube marking insertion crimping machine is suitable for preparing identified wires used in:
High- and low-voltage electrical cabinets
Power distribution cabinets
Switchgear
PLC control cabinets
Industrial automation panels
Machine control systems
Electrical equipment assemblies
Power system secondary circuits
Rail and transportation control cabinets
Renewable energy control equipment
The machine prepares the individual wires used inside these systems; it does not perform the final cabinet wiring or electrical installation.
Please provide the following information before selecting or configuring the equipment:
Wire cross-section
Wire insulation material
Required wire colors
Cutting length range
Front and rear stripping lengths
Terminal drawings and samples
Required terminal combinations
Number tube material
Tube diameter and length
Required marking content
Single-end or double-end processing
Target production capacity
Inspection requirements
Finished-wire samples or drawings
A production list showing the relationship between wire color, wire length, marking content and terminal type is especially useful for evaluating the workflow.
JMK develops integrated wire processing systems that combine several traditionally separate operations. For secondary wiring applications, this means coordinating wire selection, cutting, stripping, marking, tube insertion, heat shrinking and terminal crimping through one control system.
We support material evaluation, sample testing, applicator configuration, marking verification, machine commissioning and operator training. The equipment is configured around the actual wire list and finished lead requirements rather than a single generic specification.
It cuts and strips the wire, marks an identification tube, inserts and heat-shrinks the tube, and crimps the required terminal onto one or both wire ends.
The JM-201U uses laser marking. It does not require ink or thermal-transfer ribbon for the stated marking process.
The stated standard range is 0.3–2.5 mm². Other specifications require technical evaluation and customization.
The JM-201U supports up to 10 wire colors in its stated configuration.
Yes. The standard machine uses four terminal crimping stations, allowing several compatible terminal configurations to be included in the production program.
Yes. It supports single- or double-end stripping, double-end number tube insertion and multi-station terminal crimping according to the configured process.
No. CCD visual inspection and crimp force monitoring are listed as optional functions. Air-pressure, no-wire, no-terminal and cutting-length detection are included in the stated detection configuration.
MES connectivity is not listed in the current JM-201U specifications. If required, the communication protocol and production data requirements should be evaluated separately.
