The Fashion KPU Shoes Upper Making Machine targets the footwear sector, shaping and stitching synthetic uppers. All listed items are industrial‑grade units intended for batch or semi‑automatic production lines.

Product Range and Specialties of Dongguan Yongjia Machinery Equipment Co., Ltd.

The catalogue’s HF welding machines typically operate in a frequency band of 2  -  30 MHz with power ratings from 500 W to 5 kW, allowing weld depths of 0.2 mm to 2.0 mm on PVC or PU fabrics. Buyers often specify a welding speed of 5  -  30 m/min and a water‑resistance test of 200 mm water column for raincoat applications. For leather embossing, standard pressure ranges are 0.5  -  2 MPa and temperature settings of 120 °C  -  200 °C, compatible with vegetable‑tanned leather and PU‑coated sheets. KPU footwear upper machines usually handle material thicknesses of 0.8 mm  -  1.5 mm and include stitching modules that meet ISO 13935 for sewing strength. Industry practice also calls for CE marking, ISO 9001 quality management and, where required by the destination market, UL or EN compliance for electrical safety.

Trade and Export Information - Dongguan Yongjia Machinery Equipment Co., Ltd.

China is a leading exporter of high‑frequency welding and textile processing equipment, with major import demand from Southeast Asia, the European Union and North America. HS chapter 84, subheading 8462 covers welding and plastic‑welding machines and is the typical customs classification for the supplier’s products. Importers commonly request CE certification, ISO 9001 quality system documentation and, for the EU, the EU‑type examination certificate. Standard export packaging includes heavy‑duty wooden crates, palletized units and moisture‑proof wrapping, loaded into 20‑ft or 40‑ft containers under FOB or CIF Incoterms. Chinese export regulations require a commercial invoice, packing list and, for electronic equipment, a SAR (Special Administrative Region) declaration, which most buyers arrange with their freight forwarder.

Sourcing from Dongguan Yongjia Machinery Equipment Co., Ltd. - Buyer Guidance

When evaluating a quotation, request the machine’s technical data sheet that lists frequency range, power consumption, voltage requirements and safety certifications. Ask for a CE test report or UL listing to confirm compliance with the target market’s electrical standards, and verify that the supplier can provide a factory acceptance test (FAT) video or on‑site inspection report. Samples of welded fabric panels or embossed leather pieces are useful to assess seam strength, water‑proof rating and embossing clarity before committing to volume orders. Confirm the minimum order quantity (often one unit for pilot runs) and lead time, which typically ranges from 30 to 60 days depending on configuration and optional accessories.

What types of high‑frequency welding machines are listed in the catalogue?

The supplier offers a High Frequency Chest Wader Welding Machine, High Frequency Waterproof Plastic Welder, Automatic Hot Press Welding Machine, Raincoat High Frequency Welding Machine, PVC Fabric High Frequency Welding Machine, High Frequency Banner Welder, HF Poncho Making Machine, Chest Wader Making Machine and Waterproof Garment Making Machine.

Which materials can be processed with these welding machines?

The machines are designed for PVC, PU, KPU and other coated waterproof fabrics, as well as thin plastic sheets used in rainwear and outdoor garments. They can also handle laminated textile panels for banners and ponchos.

What certifications should a buyer verify for these machines?

Buyers should request CE marking documentation, an ISO 9001 quality system certificate and, where required, UL or EN compliance for electrical safety. Test reports for frequency accuracy and water‑proof performance are also common requirements.

What is the typical packaging and container size for shipping?

Units are usually crated in reinforced wooden boxes, palletized and wrapped in moisture‑resistant film. Standard shipments fit into a 20‑foot or 40‑foot container, depending on the machine dimensions and quantity.
