Main frame. Adopting an integral frame or column structure, bearing 400 tons of pressure and the machine weight. The frame is stress-relieved to eliminate internal stress, ensuring no deformation over long-term use.

Stainless steel hot plates. Total of 11 plates (10 openings require 11 hot plates). Manufactured from high-quality high-temperature resistant stainless steel, with surfaces precision-ground for high flatness. Optimized internal channels are designed for uniform thermal oil circulation and temperature distribution. The stainless steel material offers excellent corrosion resistance and high-temperature oxidation resistance, will not rust, and will not contaminate the boards.

Moving platen. Connects the main cylinder and the hot plate stack, transmitting pressure to each layer of boards. The platen is reinforced to minimize deflection under 400 tons of pressure.

Main cylinder. A high-precision plunger cylinder providing stable 400 tons of pressure, with good sealing performance and long service life.

Hydraulic power unit. Consists of hydraulic pumps, oil tank, motor, proportional valves, pressure sensors, safety valves, and other components, responsible for supplying and precisely controlling hydraulic pressure.

Thermal oil heating system. Includes a thermal oil boiler or electric heating device, circulation pump, piping, valves, expansion tank, and temperature controllers, heating the thermal oil and circulating it through the stainless steel hot plates.

Control system. Uses a PLC controller with a touchscreen human-machine interface, enabling setting and automatic control of parameters such as temperature, pressure, holding time, and pressing curve. Supports storage and recall of multiple process recipes.

Safety protection devices. Includes safety light curtains, emergency stop buttons, hydraulic overpressure relief valves, hot plate overtemperature sensors, leak detection devices, and more.

High-end furniture panels. Wardrobe panels, cabinet panels, TV stand panels, and other products requiring high surface cleanliness. The stainless steel heating plates cause no rust contamination, allowing direct application of decorative surfaces.

Film-faced plywood. Film-faced panels for concrete formwork and high-quality formwork panels requiring a clean board surface to ensure film adhesion.

Eco-boards. Paint-free eco-boards require a high-quality appearance, as any surface contamination will affect the final product look.

Food-grade packaging panels. Plywood used for packaging that comes into contact with food, requiring non-toxic and contamination-free boards.

Export eco-friendly plywood. Export products with strict requirements for heavy metal content and surface cleanliness.

Multi-layer solid wood flooring substrate. Requires dimensional stability and high internal bond strength.

General plywood. Suitable for the production of all types of standard plywood.

Question one: What are the advantages of stainless steel hot plates compared to ordinary carbon steel hot plates?

Answer: Stainless steel hot plates will not rust, oxidize, or flake off under high-temperature and high-humidity environments. The surface remains smooth and clean over long-term use, and no rust contamination will occur on the board surface. Additionally, stainless steel offers better corrosion resistance and stronger tolerance to acidic substances in the thermal oil. The internal channels of the hot plate are less prone to blockage, and the service life is significantly longer than that of carbon steel hot plates.

Question two: What types of boards can this hot press produce?

Answer: It is mainly suitable for plywood, film-faced concrete formwork, eco-boards, high-end furniture panels, multi-layer solid wood flooring substrates, and more. It is especially suitable for board products that have strict requirements for surface cleanliness.

Question three: What is the production capacity of the 10-layer 400-ton configuration?

Answer: Each cycle can press 10 plywood sheets simultaneously. Taking a typical 15-millimeter plywood as an example, the complete cycle time including loading, pressing, holding and curing, and unloading is approximately 8 to 12 minutes, allowing 5 to 7 cycles per hour. This corresponds to an hourly output of approximately 50 to 70 boards, depending on board thickness and adhesive type.

Question four: Can electric heating be selected as the heating method?

Answer: Yes. Thermal oil heating is the standard configuration. If the customer site does not have boiler conditions or has high environmental requirements, electric heating can be selected. Electric heating offers more precise temperature control but has higher operating electricity costs. We will recommend the most suitable solution based on the customer's actual situation.

Question five: What installation space is required for the machine?

Answer: The machine itself is approximately 6.5 meters long, 3.2 meters wide, and 3.0 meters high. Considering operation and maintenance space as well as upstream and downstream conveying equipment, we recommend reserving an installation area of no less than 8 meters in length, 5 meters in width, and 4.5 meters in height.

Question six: Do stainless steel hot plates require special maintenance?

Answer: No. Stainless steel hot plates are simpler to maintain than carbon steel hot plates. Only regular cleaning of residual glue from the surface is needed, with no concern about rust prevention. We recommend using wooden or plastic scrapers for cleaning, avoiding metal tools that could scratch the surface.

Question seven: Do you provide overseas installation and commissioning services?

Answer: Yes. We can send engineers to overseas customer sites for installation guidance, commissioning, and operator training. We also provide long-term free remote video technical support.

Question eight: What is the warranty period for the equipment?

Answer: The complete machine is warranted for 12 months from the date the equipment arrives at the customer's site. Thanks to the excellent material quality, the stainless steel hot plates themselves have a service life far exceeding the warranty period under normal use. Wear parts such as seals are not covered under warranty but can be supplied at cost long term.
