What are the specifications of plywood hot press machines
Plywood hot press machine is the core equipment for furniture manufacturing and construction template production, and its specifications directly affect production capacity, product accuracy, and applicability. How to choose a suitable hot press machine for your own needs when facing the dazzling array of models on the market? This article starts with key parameters such as the size, number of layers, pressure, and heating method of the pressure plate, and combines real cases to analyze the applicable scenarios of different specifications.
1、 Pressure plate size: determines the processing range of the plate
The size of the hot pressed board is a fundamental parameter of the equipment, which directly affects the specifications of the plywood that can be produced. For example, the size of the three-layer hot press plate is 2500 × 1300 × 42mm, which is suitable for producing 1.3-meter-wide plates; The HY214X8/6A-15 model of Hanwei Machinery has a pressure plate size of 2700 × 1370 × 42mm, which can cover 4 × 8 feet (1220 × 2440mm) standard plates and meet the requirements of export orders. Some manufacturers provide customized services, such as the 1320 dual station hot press machine supporting ecological board veneer function and flexible adjustment of pressure plate size.
2、 Layers and Opening: Balancing Production Capacity and Thickness Technique
The more layers, the higher the single hot pressing capacity. The number of layers for mainstream models ranges from 3 to 20:
Small equipment: single-layer splicing hot press machine, suitable for small batch customized production, with a hot press plate interval of 100mm, capable of pressing 100mm thick plates;
Multi layer equipment: 15 layer hot press machine (HY214X8/6A-15) can press 15 sheets of board at a time, with an opening of 70mm, suitable for producing 3-20mm thick plywood;
Ultra high rise equipment: Some manufacturers provide 20 layer hot press machines with an opening of up to 150mm, which meet the needs of thick plates such as building templates and container bottom plates.
3、 Pressure system: a leap from light to super heavy
The total pressure (tonnage) determines the applicable scenarios of the equipment:
Light equipment (40-200 tons): Yaodeli MH3248 rated pressure of 160 tons, suitable for furniture factories to produce thin plywood;
Medium sized equipment (400-600 tons): Hanwei Machinery HY214X8/8B-10 model has a pressure of 800 tons and a unit pressure of 25MPa, which can press high-density marine plywood;
Ultra heavy equipment (over 800 tons): Some manufacturers customize ultra heavy hot press machines with a unit pressure of 150-200 kilograms per square centimeter, suitable for special materials such as aviation plywood and bulletproof board.
4、 Heating method: the game between efficiency and cost
The heating system directly affects the efficiency and energy consumption of hot pressing:
Electric heating: Zhejiang New Century NM-JH-5 adopts an electric heating water boiler with precise temperature control (± 1 ℃), suitable for small batch high-end sheet metal production;
Thermal oil heating: Hanwei machinery models are equipped with coal-fired thermal oil boilers ranging from 200000 to 1.2 million kcal, which provide uniform heating and low cost, making them suitable for large-scale continuous production;
Mixed heating: Some equipment integrates a jet drying device, which quickly removes moisture from the veneer during the pretreatment stage and shortens the hot pressing cycle to 25 minutes (traditional models require 40 minutes).
5、 Automated Configuration: Upgrading from Manual to Intelligent
The degree of automation determines labor costs and production stability:
Basic models: such as Hebei Jianye JY-2, which requires manual loading and unloading of boards and is suitable for small workshops;
Semi automatic model: equipped with friction wheel conveying and vacuum suction cup positioning, reducing manual intervention;
Fully automatic production line: Hanwei Machinery integrates cutting, dust removal, and drying modules, and controls 5 stages of pressure and 6 working modes through PLC, increasing single shift production capacity by 300%.
Purchase suggestion: Match according to needs, avoid "big horse pulling small car"
Furniture factory: prioritize selecting equipment with 3-8 floors and 160-400 tons, such as Yaodeli MH3248, while considering flexibility and cost;
Construction template factory: requires equipment with more than 10 floors and 600-800 tons, such as Hanwei Machinery HY214X8/6A-15, to ensure the uniformity of thick plates;
Export oriented enterprises: Choose models that support customized pressure plate sizes and are equipped with German Siemens PLC control to meet international standards.
The selection of specifications for plywood hot press machines should take into account factors such as production capacity, board thickness, and automation requirements. Suggest conducting on-site inspections of equipment operation cases, with a focus on core indicators such as flatness of the pressure plate (≤ 0.05mm/㎡) and closing speed (≥ 4m/min), to ensure maximum return on investment.
