HIPOWER HR-25KW-2QT Automatic Car Floor Mat Welding Machine: All-In-One Hydraulic Thermal Fusion Solution for Multi-Vehicle Interior Mats

Manufacturers producing automotive full-surround mats, coil floor liners, threshold pads and heel wear-resistant pads face multiple challenges. Various vehicle designs split into LHD and RHD versions, standard machines cannot fit all sizes; thick multi-layer TPE/PVC mats suffer weak welding and peeling; material shifts cause high reject rates; frequent model changes lead to long downtime for parameter adjustment. To solve these pain points, DONGGUAN HIPOWER LTD launches HR-25KW-2QT automatic car mat HF welding machine. Hydraulic stable output and intelligent program control enable universal welding for all car models. It supports stable mass production and flexible multi-item changeover, with comprehensive non-standard customization available.

Core Technical Features of the HR-25KW-2QT

1. Stable 25KW HF Output with Multi-Stage Auto Compensation for Consistent Welding

Equipped with 25KW HF generator and premium 8T25RA electron tube running on 27.12MHz industrial frequency. Multi-level automatic high-frequency compensation circuit adjusts energy output automatically according to mat thickness and layers. Thin coil mats and thick composite mats achieve uniform firm welding lines. Welding quality remains consistent during long-time continuous production without cold joints or uneven fusion.

2. Auto Mold Recognition & Recipe Storage Speed Up Multi-Model Changeover

Built-in automatic mold identification quickly matches parameters when replacing dies for different car models. Hundreds of process recipes can be saved for all LHD/RHD mat styles, including power, hydraulic pressure and welding duration. Operators call saved data directly without repeated testing, greatly cutting model change downtime and supporting flexible small-batch production for auto accessory factories.

3. Vacuum Adsorption Fixes Materials to Prevent Position Deviation

Professional vacuum positioning system locks mat materials tightly on the worktable, avoiding sliding and stretching during hydraulic pressing. Edges of full-surround mats and irregular threshold pads are precisely fused, lowering reject rate and trimming labor cost caused by material misalignment.

4. Auto Pressure Tracking Enables Multi-Directional Welding for LHD & RHD Vehicles

Real-time pressure tracking system automatically switches welding modes for flat surface and wrapped side edges. Multi-angle welding fits both domestic left-hand-drive cars and overseas right-hand-drive vehicles. Exporters only need one machine to cover all mainstream global car models without purchasing separate equipment.

5. 2T~5T Hydraulic Pressure Delivers Steady Heavy Force for Thick Materials

Hydraulic driving provides stronger and more uniform pressure than pneumatic machines within the range of 2 tons to 5 tons. It ensures deep reliable fusion for thick rubber, TPR and TPE composite mats with enhanced water resistance and abrasion resistance. Higher hydraulic pressure can be customized for extra-thick special interior pads.

6. European Oscillation Cabinet & Advanced RF Shielding for Safety

European standard square oscillation cabinet features solid circuit structure with stable HF output and low failure rate. Advanced high-frequency radiation shielding meets international safety standards, reducing RF exposure and protecting operators during long daily shifts.

7. Full Customization & Complete ODM/OEM Support

Worktable electrode size, machine frame dimension, hydraulic limit and electrode stroke are all freely customizable. Power options cover 15KW/25KW/35KW, with private-label ODM & OEM available. We extend table size, add automatic sliding tables or feeding robots according to mat dimension and workshop layout to build exclusive production lines.

Frequently Asked Questions

Can HR-25KW-2QT weld oversized full mats for RV and large SUV?

Yes. Worktable size has no fixed maximum limit. We customize extended wide-length tables to fit extra-large floor mats for vans, RVs and big SUVs.

Do factories need two separate machines for LHD and RHD mats?

No. Multi-angle welding allows users to switch between LHD and RHD production simply by changing molds. Saved recipes streamline product changeover efficiently.

Can hydraulic pressure be upgraded for ultra-thick multi-layer rubber mats?

Hydraulic pressure can be customized above 5 tons to meet high-intensity welding requirements of heavy thick composite materials.

Can we add auto sliding tables to connect assembly lines for automation upgrade?

Electric sliding tables and automatic loading/unloading devices are customizable. The machine can connect to assembly lines to build low-labor automated workshops.

What is the warranty policy for customized machines?

1-year full machine warranty plus lifelong remote technical support. Engineers offer on-site installation, commissioning and operator training. All technical inquiries get response within 24 hours.
