Additional machines such as the Curved Plywood Hot Press, HF Wood Bending Press, and various RF‑driven jointing and edge gluing units address specialized woodworking operations. The supplier also provides a High Frequency (Radio Frequency) Generator that powers the drying and shaping equipment. For office equipment, the catalogue includes an HP2500 Color Laserjet Printer, representing the computer printers segment. Together, these items cover key processes from raw lumber conditioning to finished product assembly.

Product Range and Specialties of Shijiazhuang Duotian Machinery Co., Ltd.

Shijiazhuang Duotian Machinery’s catalogue contains sixteen distinct machines, primarily high‑frequency (HF) or radio‑frequency (RF) wood processing units and a single color laser printer. The HF wood dryer and timber drying kiln operate at frequencies around 40 MHz, delivering power levels up to 10 kW to achieve moisture contents below 8 % for hardwoods within 8‑12 hours, depending on wood thickness. The board jointing and edge gluing machines are equipped with belt‑driven presses delivering clamping forces of 150 - 250 kN and precision alignment tolerances of ±0.2 mm. The Curved Plywood Hot Press and Bending Wood Press provide temperature control up to 220 °C and pressure ranges of 1.5 - 3 MPa, suitable for multi‑layer veneer forming. The HP2500 Color Laserjet Printer offers a print speed of 20 pages per minute and a resolution of 1200 dpi, typical for office‑grade laser devices.

In the wood‑working machinery sector, buyers commonly specify drying kilns with moisture measurement accuracy of ±0.2 % and RF generators certified to IEC 61846 for electromagnetic compatibility. Jointing machines are often required to meet ISO 9001 quality management and to provide CNC‑controlled feed rates between 1‑5 m min⁻¹. Hot press units are evaluated against ASTM D2033 for temperature uniformity and pressure distribution. For laser printers, CE marking and compliance with ISO 12647‑2 for colour management are standard expectations. Exporters from China typically package these machines in wooden crates or steel frames, loading them into 20‑ft or 40‑ft containers with a gross weight limit of 22‑24 t per container.

Trade and Export Information - Shijiazhuang Duotian Machinery Co., Ltd.

China is a major exporter of wood‑processing machinery, with the majority of shipments destined for North America, Western Europe, and Southeast Asian markets. The HS‑code 8465 00 (machinery for working wood) and 8429 90 (other woodworking machinery) cover most of the HF drying and press equipment listed by Duotian, while HS‑code 8471 30 applies to the HP2500 laser printer. Buyers in these regions usually request CE conformity, ISO 9001 certification, and test reports demonstrating compliance with IEC 61846 (RF safety) and ISO 14001 (environmental management).

Typical export logistics involve FOB shipping from ports such as Tianjin or Qingdao, with containers sealed under the buyer’s supervision. Freight forwarders often use 20‑ft containers for single units or 40‑ft containers for multiple smaller machines, employing wooden dunnage and shrink‑wrap to protect delicate components. Import regulations may require pre‑shipment inspection under China’s AQSIQ or the importing country’s customs authority, especially for equipment exceeding 1 t. Buyers frequently ask for a Packing List, Commercial Invoice, and Certificate of Origin to facilitate customs clearance.

Sourcing from Shijiazhuang Duotian Machinery Co., Ltd. - Buyer Guidance

Prospective buyers should request the supplier’s CE Declaration of Conformity, ISO 9001 certificate, and detailed performance data for each HF drying or press machine, including power consumption, drying curves, and pressure‑temperature charts. For the RF generator, an EMC test report confirming compliance with IEC 61846 is essential before integration into a production line. Sample units are generally offered on a paid basis, allowing verification of drying uniformity, clamping precision, and printer output quality.

Before placing an order, verify the machine dimensions and weight against container loading plans to ensure efficient packing. Confirm the standard lead time, which for most of the listed equipment ranges from 30 to 60 days after receipt of a pro‑forma invoice, and negotiate the Incoterm (FOB or CIF) that matches the buyer’s logistics strategy. Request a warranty document covering at least 12 months for mechanical parts and 6 months for electronic components, together with a spare‑parts catalogue.

What types of wood‑processing machinery does Duotian offer?

The catalogue includes high‑frequency wood dryers, timber drying kilns, RF board jointing machines, edge gluing units, curved plywood hot presses, bending wood presses, and a single RF generator that powers these systems.

Which certifications should a buyer request for the HF drying equipment?

Buyers should ask for CE marking, an IEC 61846 EMC test report, and the supplier’s ISO 9001 quality‑management certificate to confirm safety and performance compliance.

What are the typical technical specifications for the HF wood dryer?
