CORTJ-RL23 Shoelace Hot Melt Head Machine

The CREDIT OCEAN CORTJ-RL23 is an automatic shoelace tipping machine that uses heat to form cord ends without tipping film or adhesive. PLC control supports parameter setting and automatic counting. Send your cord sample and required end shape to confirm material suitability and tooling.

Finished Shoelace Tip Reference

Reference samples show the transition from flat lace to a narrow tip. Send your own lace and target tip dimensions to confirm the finish on CORTJ-RL23.

Main Features

• Five pieces formed per cycle.

• PLC parameter setting and automatic counting.

• Replaceable molds selected by cord thickness and end shape.

• Square, round, flat and oval shapes, depending on tooling.

• Custom tooling and logo requirements can be discussed with a sample or drawing.

Materials and Applications

Applications include nylon cord, PP cord, elastic tape, printed tape and twisted rope, subject to sample testing. For blended yarns or coated cords, provide the full composition: the outer fibers and coating affect the thermal forming result.

Formed ends can be prepared for subsequent adhesive application, injection molding or fitting end accessories. Confirm the next process and required end dimensions during sample testing.

Choose the Mold for Your Cord End

For a round cord, measure its diameter. For a flat lace, measure both width and thickness. Specify the finished tip length and cross-section so we can match the mold to the sample. Square, round, flat and oval profiles are listed options. If the tip must pass through an eyelet or fit a buckle, include the opening dimensions.

Buyer Questions

Does CORTJ-RL23 require acetate tipping film?
No. The thermal forming process does not require tipping film or adhesive.

What should I check on a trial sample?
Check that the tip fits the eyelet or accessory, matches the required length and shape, and holds together when the lace is handled.

What utilities are required?
The listed electrical supply is 220 V with 3.2 kW power. Compressed air pressure must be at least 0.6 MPa.

Can the ends be used for further molding?
Formed ends can be prepared for injection molding, adhesive application or fitting end accessories. Confirm the required dimensions and next process with a sample.

Request a Sample Test and Quotation

Send the cord material, diameter or width, required tip shape and length, target output, voltage and sample photos. Include any logo or subsequent molding requirements. CREDIT OCEAN can then confirm the tooling and machine specification.
