ZJ-5K-8K-10K-Y Double-Head Hydraulic HF Welding Machine

The ZJ-5K-8K-10K-Y is a double-head hydraulic high-frequency welding machine from Zhenjia Machine, a manufacturer of high-frequency (HF) welding equipment. The recorded configuration combines a 5 kW-10 kW power band, a 27.12 MHz working frequency, an oil-hydraulic drive, a 380 V power supply and 1.5 T pressure in a double-head design that is listed for shoe upper and canvas embossing. This page records what is confirmed for the model, what still has to be checked against your own sample and tooling, and what to prepare before a quotation is issued.

HF welding results depend on the material stack, the electrode or tooling geometry and how the head is set up, so the model code alone does not fix output, cycle time or the acceptable material range. Those points are settled with a physical sample and the production tooling before an order is released.

Key Configuration at a Glance

• Double-head design – two welding heads on one hydraulic frame, as recorded for this model.
• Power band: 5 kW-10 kW.
• Frequency: 27.12 MHz.
• Drive: oil-hydraulic.
• Power supply: 380 V.
• Pressure: 1.5 T.
• Listed applications: shoe upper and canvas embossing.
• Output, dimensions and certification scope: not specified – confirm before quotation.

Specifications and Electrical Configuration

The power band spans 5 kW to 10 kW, so the exact rating for a given machine is confirmed on the quotation. The recorded supply is 380 V; frequency, phase and the plug or terminal arrangement are confirmed against the site before shipment.

Double-Head Design and 1.5 T Pressure on the Production Floor

Two welding heads sit on a single oil-hydraulic press frame. For footwear upper work and canvas embossing, that arrangement allows one machine to carry two tooling positions or two related operations, which suits workshops that switch between articles rather than running one dedicated single-purpose press. Head spacing, table dimensions and the usable tooling envelope are not fixed in the current record and are confirmed from your drawing.

The 1.5 T figure is the recorded clamping pressure of the hydraulic system. Whether 1.5 T suits a given part depends on the contact area of the electrode, the compressibility of the material stack and the depth of emboss required, so the production pressure setting is established on your sample rather than assumed from the catalogue value.

What Has to Be Confirmed with Tooling

• Electrode or die size and the working area it needs.
• Head spacing and the part envelope for double-head operation.
• Whether both heads run identical tooling or two different tools.
• Clamping pressure setting validated on the actual material stack.
• Jig or fixture design for repeatable part location.

Material and Application Compatibility

Shoe upper and canvas embossing are the applications listed for this model. The wider material set – which shells, cards, films, coated fabrics or PVC-containing stacks can be run – is not fixed in the current record. Send the actual material, its thickness and any lining or laminate together with a drawing or a finished part, and the compatibility check is run on that sample with the production tooling. Materials that look similar can behave differently at 27.12 MHz, so a sample trial is the only reliable basis for a compatibility answer.

For buyers in Malaysia, Indonesia and Vietnam the sequence is the same: confirm tooling, material samples and site voltage first, then quotation.

Configuration Check Before Quotation

1. Material and sample drawing, including thickness and any lining.
2. Tooling and working envelope, including head spacing for two-head operation.
3. Target output and shift pattern.
4. Site voltage, frequency and hydraulic or air supply available.
5. Destination country and certification scope.

Supplying all five points in one message usually removes at least one round of questions and lets the quotation cover tooling as well as the machine.

Installation Notes for Malaysia, Indonesia and Vietnam

The recorded supply is 380 V. Confirm frequency, plug or terminal standard and the actual site voltage before shipment, and check the proposed installation point rather than the nominal factory figure.

• Voltage stability: confirm whether a stabiliser is required for the site.
• Humidity and heat: plan ventilation and moisture control around the cabinet, particularly in coastal or un-airconditioned buildings.
• Grounding: verify the factory earth before commissioning.
• Hydraulic system: confirm oil grade, top-up procedure and cooling requirement from the machine manual.
• Certification: check SIRIM, SNI, QCVN/TCVN or CE scope for this exact model with your importer; no certificate is claimed on this page.

Safety and Routine Maintenance

CRITICAL SAFETY NOTICE: Before changing tooling, clearing a jam or opening any guard, isolate the main power, lock it out and bleed residual hydraulic pressure. Adjustment of the sealing head or the electrical cabinet is for trained personnel only; other operators should not open the cabinet. Confirm the lockout procedure and the pressure values in the machine manual.

• At each shift start, verify the emergency stop and guard interlocks.
• Inspect hydraulic lines, fittings and seals for leaks and weepage.
• Keep the electrode, sealing head and platen clean and free of material build-up.
• Follow the manufacturer schedule for lubrication, filter replacement and electrical inspection.

Selection FAQ

What is the ZJ-5K-8K-10K-Y used for?
It is a double-head hydraulic HF welding machine listed for shoe upper and canvas embossing; confirm the material and tooling with a sample.

How to Request a Quotation

Send material samples or a finished part, a drawing of the part and the tooling you expect, your target output and shift pattern, the site voltage and the destination country. Zhenjia Machine will reply with the confirmed configuration, the items that still have to be fixed for this model, and the tooling requirement.

double-head hydraulic HF welding machine: selection and next steps

When comparing a double-head hydraulic HF welding machine, confirm the material, tooling, cycle time and site voltage before quotation. A double-head hydraulic HF welding machine should be matched to the actual product, output target and operator model, not only to the machine size.
