HIPOWER HR-10KW-20T Automotive Interior HF Welding Machine: Custom One-Stop Solution for Interior Parts Welding & Cutting

Manufacturers of automotive interior parts such as sun visors, window shades, trunk tonneau covers, pollen filters, sound insulation cotton and AC filter bags face common challenges. Standard machines have fixed pressure levels and cannot flexibly adapt to interior parts of different thicknesses and materials. PVC, composite fabric and filter cotton materials easily suffer from weak welding, delamination and burrs after cutting. Single-station machines waste time on loading/unloading with low productivity. Interior parts vary in size across vehicle models, and standard machines can hardly meet customized production demands.

To solve these pain points, DONGGUAN HIPOWER LTD launches HR-10KW-20T high frequency welding machine for automotive interior trims. Equipped with a stable high-Q oscillation system, it supports customizable cutting force from 1T to 20T, offers pneumatic-hydraulic and full hydraulic press modes, and optional single-side auto sliding table. One machine covers welding and cutting of various automotive interior parts, with full non-standard customization available.

Core Technical Features of the HR-10KW-20T

1. Stable 10KW High-Q Oscillation Tube for Multi-Material Welding

Equipped with 10KW HF power and premium E3069 electron tube running on 27.12MHz industrial frequency, the high-Q oscillation circuit delivers uniform and stable energy output. The energy is optimized for automotive interior materials such as PVC fabric, composite textiles, filter cotton and non-woven fabrics, creating firm weld seams and clean cut edges without burrs. No secondary trimming is required, meeting high-quality processing standards for automotive interiors.

2. Customizable Cutting Force 1T–20T with Robust Structure

The cutting force can be customized over a wide range from 1T to 20T. Pressure parameters are configured individually based on material thickness, layers and die size. The machine features a robust structure with stable and reliable output. It delivers consistent welding and cutting results for both thin sun visor fabrics and thick sound insulation cotton or multi-layer filter bags, with low deformation and smooth cutting surfaces.

3. Optional Press Modes for Flexible Process Matching

Two press modes are available: pneumatic-hydraulic and full hydraulic. Customers can select the best solution based on interior part process and material thickness. Pneumatic-hydraulic mode offers fast response and high efficiency for regular interior parts welding and cutting. Full hydraulic mode delivers heavy and stable pressure for thick materials, multi-layer composite parts and large die cutting.

4. Optional Single-Side Auto Sliding Table for Safety & Efficiency

Customizable single-side automatic sliding table is available, with separate welding and loading zones for safer operation. The sliding table runs alternately under preset program. While one station is welding, the other allows loading and unloading at the same time, eliminating idle waiting time and effectively improving productivity for mass production of automotive interior parts.

5. High-Sensitivity Anti-Flash Protection for Mould Safety

Optional high-sensitivity 557 anti-flash system cuts HF power within milliseconds when abnormal flash occurs. It effectively protects welding moulds, cutting dies and internal core components, reducing mould maintenance cost during frequent product changeover and supporting long-time continuous production.

6. Full Customization & Complete ODM/OEM Support

Electrode size, worktable dimension, cutting force, sliding structure and power rating can all be customized. Special fixtures, automatic positioning structures and multi-station rotary designs can be tailored for specific vehicle interior parts. Private-label ODM & OEM service is provided to build exclusive automotive interior welding production lines based on customer workshop layout and product features.
